To summarize and systematically analyze the efficacy of laser acupuncture (LA) interventions in reducing pain scores in patients suffering from chronic low back pain (LBP). PubMed, EMBASE, and Scopus databases were searched for randomized controlled trials, published in peer-reviewed journals, and reporting LA interventions in patients with chronic LBP. All included studies had a comparison group of patients, receiving placebo treatment, sham intervention, conventional therapy, or no treatment. The outcome of interest was the pain intensity score. Pooled effect estimates were calculated using random-effects models and reported as weighted mean difference (WMD) with 95% confidence intervals (CI). A total of 20 studies were included. Compared to the control group, patients who underwent LA experienced a significant reduction in reported pain scores immediately after completing the treatment (WMD –1.14, 95% CI: –1.68 to –0.61). High dose of LA was associated with a more significant decrease in the pain scores (WMD –1.40, 95% CI: –1.94 to –0.85; N = 15, I 2 = 81.0%). However, reported pain scores of patients who received LA were statistically similar to those of the control group at short-term (4-8 weeks after the treatment) and long-term (12 months) follow-ups. In patients with chronic LBP, LA may help in alleviating pain immediately after the treatment. However, this effect does not appear to be sustained on later follow-up assessments. Consequently, patients should be informed about the potential limitations of the treatment in providing lasting pain relief. [ABSTRACT FROM AUTHOR]

Acupuncture has shown promise as a therapeutic option in temporomandibular disorders (TMD). Its benefits include pain relief, reduction of muscle tension and improvement of jaw function. Several alternative approaches, including dry needling and laser acupuncture, were also reported to improve TMD symptoms. This review aims to summarise the most recent studies available on these alternative therapies for TMD. An electronic literature search was conducted in 3 databases, PubMed, Web of Science, and Scopus, in order to identify articles on acupuncture, dry needling, or laser acupuncture. Search development, process, and two-step article selection were conducted by independent researchers. Data was extracted regarding study characteristics, population characteristics, acupuncture points or techniques used, and assessment methods for diagnosis and effects. Out of 431 identified results, 20 were selected for inclusion. We identified 11 studies on acupuncture, 3 studies on laser acupuncture and 6 studies on dry needling. Most studies showed improvement of TMD symptoms post-intervention, assessed by pain scales and maximum mouth opening. Overall, most studies showed promising results for acupuncture as an alternative, minimally invasive treatment method for TMD. When compared to controls or placebo, acupuncture, and related techniques result in significant relief of TMD symptoms. [ABSTRACT FROM AUTHOR]

Abstract Background Laser acupuncture is a proven non-invasive treatment with effects comparable to traditional acupuncture in different types of headaches, but there is still insufficient evidence for chronic migraine (CM) in adults. We aim to investigate the efficacy and safety of laser acupuncture (LA) as an add-on preventive therapy on CM. Methods A single-blind randomized controlled trial was conducted from January 2022 to November 2023. CM patients with unsatisfactory pharmacological effects were randomly assigned in a 1:1 ratio to receive either LA or sham treatment over a course of 8 sessions spanning 4 weeks. The co-primary outcomes were changes in monthly migraine days (MMD) and acute headache medications usage days per month from baseline. Evaluations were taken at baseline (12 weeks before randomization), at 4th week (treatment completed), 8th week and 12th week from baseline. Results A total of 60 patients (30 in each group) were included in the intention-to-treat analyses. Baseline headache characteristics between trial groups were similar. Compared with the sham group, the LA group had a significant reduction in MMD (5.2 vs. 1.5 days at 8th week, p = 0.015; 7.3 vs. 1.8 days at 12th week, p = 0.001), and acute headache medications usage days per month (3.1 vs. 0.4 days at 4th week, p = 0.007; 3.2 vs. 0.0 days at 8th week, p = 0.005; 3.9 vs. 0.0 days at 12th week, p

No serious adverse event was observed in both groups. Conclusions: Laser acupuncture was effective in reducing MMD and acute headache medications usage with promising safety. Specifically, the efficacy of LA exhibited a progressively more pronounced effect within the follow-up period. We suggested that LA is a promising add-on preventive therapy for CM, and trials focused on investigating the mechanism of LA's effect and its long-term effects on CM prevention are justified.

To study the laser acupuncture (LA) effects on postmenopausal obese women's metabolic syndrome. Randomized controlled trial. Benha university hospital. Thirty postmenopausal women were randomized into two equal groups. Group A received a diet regimen and Group B received LA treatment for 30 min three times a week for two months beside the diet regimen. Included weight (W), body mass index (BMI), waist (WC), hip (HC), waist-hip ratio (WHR), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum level of total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), fasting blood glucose (FBG), fasting blood insulin (FBI), homeostatic model assessment-insulin resistance (HOMA-IR) before and after the end of treatment. The study's findings showed that both groups experienced a highly statistically significant decrease in the post-testing mean value of W, BMI, WC, HC, WHR, SBP, DBP, TC, TG, LDL, FBG, FBI, and HOMA-IR, while both groups experienced a significant increase in the post-treatment mean value of HDL (p 0.0001). The posttreatment SBP, DBP, TC, TG, LDL, FBS, FBI and insulin resistance were significantly lower while HDL was significantly higher in women who received combined LA and diet regimen compared to those who received dietary regimen only. LA beside the nutritional intervention is a physical therapy technique that may be used safely, easily, and effectively to minimize metabolic syndrome features during menopause.

Objective: To explore the clinical effect of laser acupuncture combined with Schroth therapy on adolescent idiopathic scoliosis (AIS). Method: This was a retrospective study. Eighty AIS patients were admitted to The Second People's Hospital of Dalian from March 2021 to March 2022 and divided into control group and experimental group according to the treatment method, with 40 cases in each group. The control group received Schroth therapy, and the experimental group received Schroth therapy and laser acupuncture therapy (MLS® laser). All treatments are performed five times a week for four consecutive weeks we compared the clinical effects of the two groups before treatment, six months and 12 months after treatment, and compared the improvement of Cobb angle, axial trunk rotation (ATR), musculoskeletal stiffness(The PulStarG3 system), and gait evaluation (Micro-Electro-Mechanical System(MEMS) between the two groups of patients. Result: After four weeks of treatment, the spinal condition of both groups of patients improved. After treatment, the experimental group showed greater improvement in Cobb angle, ATR, spinal range of motion, gait parameters, and clinical efficacy compared to the control group (p<0.05). Conclusion: Laser acupuncture combined with Schroth therapy is safe and effective in the treatment of AIS, and is more effective in correcting scoliosis and related problems of AIS.

Purpose of Review: Laser acupuncture (LA) demonstrates promising results in the treatment of musculoskeletal disorders. However, its effects on temporomandibular disorder (TMD) are not yet fully understood. Thus, the aim of this systematic review and network meta-analysis was to assess the effectiveness of LA on pain intensity and maximum mouth opening range (MMO) related to TMD. A search was carried out in 11 electronic databases and references of included studies to locate randomized clinical trials (RCTs) that evaluated LA as a primary treatment for TMD. The risk of bias was assessed using the RoB 2 tool. Network meta-analysis was conducted on the MetaInsight platform, considering the pain intensity and counseling (C) as the outcome of reference. The GRADE system was used to assess the certainty of the evidence. Recent Findings: Five studies evaluated pain intensity, four with a high risk of bias and one with a low risk. Two studies evaluated pain intensity on palpation (one with high and one with low risk of bias), and one study with high risk of bias evaluated MMO. Laser parameters were: 690–810 nm, 40–150 mW, and 7.5–112.5 J/cm2. Occlusal splint (OS) [− 2.47; CI 95% − 3.64, − 1.30] and Physiotherapy (PT) [–2.64; CI 95% − 3.94, − 1.34] reduced pain intensity compared to C. The ranking of treatments in order of effectiveness was PT > OS > LA > C > CR (craniopuncture). The certainty of the evidence was very low or low. Summary: The data do not support the indication of LA for the treatment of TMDs and new placebo-controlled RCTs must be conducted to demonstrate its effectiveness more precisely.

Background: Obesity is a global concern, driving the search for alternative treatments beyond lifestyle changes and medications. Laser acupuncture (LA) shows promise in obesity management, yet few studies compare it with FDA-approved medications. This study aimed to assess and compare LA's impact with liraglutide on weight reduction in obese individuals. Methods: Data from the Chang Gung Research Database (CGRD) (2013–2018) were analyzed. Primary outcomes included changes in body weight and BMI within 180 days, with secondary outcomes measuring the proportion achieving 5%, 10%, and 15% weight loss. Adverse events were also assessed. Results: Of 745 subjects (173 LA users, 572 liraglutide users), LA users lost more weight by day 180 (5.82 ± 4.39 vs. 2.38 ± 5.75 kg; p < 0.001) and had a greater BMI reduction (−2.27 ± 1.73 vs. −0.93 ± 2.25 kg/m2; p < 0.001). More LA users achieved 5% and 10% weight loss compared to liraglutide users (64.2% vs. 22.7%, 26.6% vs. 4.2%; all p < 0.001). After balancing baseline differences, LA's benefits remained significant. No adverse events were reported with LA. Conclusions: LA may offer superior weight reduction compared to liraglutide. Future studies should explore LA alone or in combination with liraglutide for obesity management. [ABSTRACT FROM AUTHOR]

Introduction: Electroacupuncture (EA) has been applied in dysmenorrhea and has shown good efficacy. The mechanisms of EA are associated with autonomic nervous system adjustments and neuroendocrine regulation. Laser acupuncture (LA), however, has been widely investigated for its noninvasiveness. However, it remains uncertain whether LA is as effective as EA. This study aimed to compare EA and LA head to head in dysmenorrhea. Methods: A crossover, randomized clinical trial was conducted. EA or LA was applied to selected acupuncture points. Participants were randomized into two sequence treatment groups who received either EA or LA twice per week in luteal phase for 3 months followed by 2-month washout, then shifted to other groups (sequence 1: EA > LA; sequence 2: LA > EA). Outcome measures were heart rate variability (HRV), prostaglandins (PGs), pain, and quality-of-life (QoL) assessment (QoL-SF12). We also compared the effect of EA and LA in low and high LF/HF (low frequency/high frequency) status. Results: Totally, 43 participants completed all treatments. Both EA and LA significantly improved HRV activity and were effective in reducing pain (Visual Analog Scale [VAS]; EA: p < 0.001 and LA: p = 0.010) and improving QoL (SF12: EA: p < 0.001, LA, p = 0.017); although without intergroup difference. EA reduced PGs significantly (p < 0.001; δ p = 0.068). In low LF/HF, EA had stronger effects than LA in increasing parasympathetic tone in respect of percentage of successive RR intervals that differ by more than 50 ms (pNN50; p = 0.053) and very low-frequency band (VLF; p = 0.035). Conclusion: There is no significant difference between EA and LA in improving autonomic nervous system dysfunction, pain, and QoL in dysmenorrhea. EA is prominent in PGs changing and preserving vagus tone in low LF/HF; yet LA is noninvasive for those who have needle phobia. Whether LA is equivalent with EA and the mechanism warrants further study. Clinical trial identification number: NCT04178226. [ABSTRACT FROM AUTHOR]

Background : : Olfactory dysfunction is a common COVID-19 symptom, posing treatment challenges.Objectives: We aimed to investigate the efficacy of frequency-controlled ear acupuncture in treating COVID-19-related olfactory dysfunction.Methods : : A randomized, participant-blind clinical trial occurred at the Rasoul Akram Hospital (IRCT20210311050671N1). Forty patients were recruited, and 20 patients were randomly assigned to either the experimental or control group. The primary outcome was the improvement in patients’ quality of smell. The olfactory dysfunction was confirmed using the Smell Identification Test. The intervention group received two sessions of acupuncture treatment according to auricular frequency treatment, with a one-week interval, while the control group received an equal number of switched-off laser sessions. Both groups were instructed to use nasal betamethasone drops. The patients were asked to rank their ability to smell before and after each intervention on a 10-point visual analog scale. Secondary outcomes were related side effects.Results : : Covariance analysis revealed a significant difference in adjusted scores between the groups (F [37, 1] = 37.463; p = 0.000, Eta2 = 0.503). The smell quality improved from 2.80 ± 1.76 to 5.22 ± 3.40 after treatment in the intervention group (p = 0.007), while the control group showed no significant change (p = 0.184). Three patients reported short and transient side effects, such as nausea, headache, and dizziness, in the first hours after the intervention.Conclusion : : Frequency-controlled ear acupuncture is an effective option for treating COVID-19-related olfactory dysfunction. The study highlights the potential of alternative therapies in the treatment of this condition, and further research is warranted to investigate its long-term effects.

Background : Obesity is a global health challenge. Traditional approaches, including increased physical activity, dietary interventions, and medical therapy, often yield limited success, propelling some patients toward costly and invasive procedures like bariatric surgery. Laser acupuncture has been suggested as a complementary therapeutic approach to overcome this challenge. The present study investigated the effectiveness of laser acupuncture treatment in weight loss and abdominal subcutaneous fat reduction. Methods : A randomized, blinded, sham-controlled clinical trial was conducted, with 30 subjects each in the intervention and control groups. Patients in the intervention group underwent 12 sessions of laser acupuncture treatment within a month (three sessions/week), whereas those in the control group received sham laser treatment on identical acupoints. The patients were instructed not to alter their physical activity levels or dietary regimens. All parameters were evaluated before and after the treatment. Results : Significant reductions in weight, body mass index, and waist circumference were noted in both intervention and control groups. Further analysis revealed a more significant decrease in the laser acupuncture group. Abdominal sonography revealed a marked decrease in periumbilical fat thickness in the intervention group. Conversely, laboratory evaluations showed no significant difference between the two groups. Conclusion : Laser acupuncture is an effective method for weight loss in patients with periumbilical abdominal fat. The observed impact on subcutaneous fat suggests its potential as a non-invasive intervention for individuals seeking weight management alternatives. Further research is warranted to validate these findings and explore the underlying mechanisms of laser acupuncture in adipose tissue modulation.

To investigate the efficacy of laser acupuncture and photobiomodulation therapy in alleviating symptoms among patients diagnosed with Bell's palsy with duration of greater than 8 weeks. The randomized controlled trial has been performed from May 2021 to April 2023. Patients were eligible who had Bell's palsy with duration of greater than 8 weeks on out-patient Department of Otorhinolaryngology in Beijing Tongren Hospital. The laser acupuncture group received class IV laser treatment for 3 times per weeks, a total of 72 times. The control group received the same treatment procedure except the laser parameter. The primary outcome measures comprised House–Brackmann facial nerve grading system and electroneurography. Secondary outcome measures comprised Sunnybrook facial grading system, electromyography, and the blink reflex. A total of 84 participants were included (42 control group, 42 laser acupuncture group). After treatment, House–Brackmann facial nerve grading system (OR, 0.11; 95% CI, 0.04–0.30; P < 0.001), and the pathologic numbers of electroneuronography were statistically different between the laser acupuncture group and control group, including orbicularis oculi (OR,0.08; 95% CI, 0.02–0.21; P < 0.001), Frontalis muscle (OR,0.14; 95% CI, 0.05–0.39; P < 0.001), Orbicularis oris (OR,0.13; 95% CI, 0.04–0.36; P < 0.001), Ala nasi muscle (OR,0.06; 95% CI, 0.02–0.18; P < 0.001). In secondary outcomes, Sunnybrook facial grading system, has significant difference between the two groups (20.26; 95% CI, 14.69 to 25.83; P < 0.01). Latency by ENoG, include orbicularis oculi (-0.61; 95% CI, -0.43 to -0.09; P < 0.001), frontalis muscle (-0.12; 95% CI, -0.21 to -0.03; P < 0.01), orbicularis oris (-0.28; 95% CI, -0.41 to -0.16; P < 0.001), and ala nasi muscle (-0.26; 95% CI, -0.38 to -0.16; P < 0.001). All amplitudes of MUAPs and durations by electromyography (EMG) showed statistically significant differences compared with the control group after treatment. For the frontalis muscle, the amplitude of MUAPs was -64.23 (95% CI, -80.89 to -47.56; P < 0.001) and duration was -1.18 (95% CI, -1.49 to -0.87; P < 0.001). For orbicularis oris, amplitude of MUAPs was -29.82 (95% CI, -55.03 to -4.62; P = 0.02) and duration was -0.57 (95% CI, -0.94 to -0.20; P < 0.001). For depressor angulli oris, amplitude of MUAPs was -47.06 (95% CI, -62.15 to -31.97; P < 0.001) and duration was -2.21 (95% CI, -2.69 to -1.72; P < 0.001). Blink reflex, including R1 (OR, 0.03; 95% CI, 0.01–0.16; P <.001), R2 (OR, 0.04; 95% CI, 0.004–0.29; P <.001), and R2 latency differences (OR, 0.15; 95% CI, 0.05–0.51; P <.001), have significant difference between the two groups, respectively. The findings suggest that laser acupuncture relieve symptoms for patients with Bell's palsy with a duration of greater than 8 weeks. Trial registration: ClinicalTrials.gov Identifier: NCT05846217.

Background and aim: Nocturnal enuresis (NE) is prevalent in children and adolescents and affects their social life later. Therefore, the objective of this study was to ascertain laser acupuncture (LA) therapy's effect on NE in adolescent females. Methods: Sixty adolescent females diagnosed with chronic monosymptomatic nocturnal enuresis (MNE) were randomly divided into two equal groups: The intervention group (received LA and desmopressin) and the control group (received desmopressin only) (n = 30 each). Treatment was delivered and LA was used three times a week for 12 successive weeks. Abdominal ultrasonography and voiding calendar were used to assess bladder capacity and maximum voiding volume (MVV), respectively. The frequency of bed wetness was assessed throughout the trial period in a diary. Results: Statistically significant differences were reported in the intervention group. Bladder capacity significantly increased in the intervention group (LA and desmopressin) than in the control group. Conclusions: The results of this study suggest the beneficial influences of LA on MNE, despite the very poor quality of the literature's available evidence. [ABSTRACT FROM AUTHOR]

Currently, the prevention, assessment, and management of procedural pain in neonates continues to challenge clinicians and researchers. Objective. To investigate the analgesic effect of low-level laser therapy (LLLT) during heel lance compared to breast milk (BM) feeding in healthy term neonates. In this randomized controlled trial, healthy term neonates who underwent heel lance were randomly assigned to an LLLT or a BM group. The LLLT group received laser therapy to the heel lance site for 20 s before heel lance. The BM group received 5 mL expressed BM via a syringe before heel lance. The primary outcomes were behavioral responses. The secondary outcomes were physiological responses and levels of salivary cortisol and α-amylase. A total of 125 neonates were included, of whom 55 in the LLLT group and 59 in the BM group completed the study. There were no significant differences in latency to first cry and cry duration between the two groups. The squeeze time was significantly shorter in the LLLT group than in the BM group (p = 0.047). There were no significant differences in pain scores, heart rate, respiratory rate, oxygen saturation, and blood pressure before and after heel lance between the two groups. There were no significant differences in salivary cortisol and α-amylase levels in the LLLT group before and after heel lance; however, the differences were significant in the BM group. These findings suggest that the analgesic effect of LLLT is similar to that of BM during heel lance in healthy term neonates. LLLT has potential as an analgesic treatment. [ABSTRACT FROM AUTHOR]

Background: Obesity is a global concern, driving the search for alternative treatments beyond lifestyle changes and medications. Laser acupuncture (LA) shows promise in obesity management, yet few studies compare it with FDA-approved medications. This study aimed to assess and compare LA’s impact with liraglutide on weight reduction in obese individuals. Methods: Data from the Chang Gung Research Database (CGRD) (2013–2018) were analyzed. Primary outcomes included changes in body weight and BMI within 180 days, with secondary outcomes measuring the proportion achieving 5%, 10%, and 15% weight loss. Adverse events were also assessed. Results: Of 745 subjects (173 LA users, 572 liraglutide users), LA users lost more weight by day 180 (5.82 ± 4.39 vs. 2.38 ± 5.75 kg; p < 0.001) and had a greater BMI reduction (−2.27 ± 1.73 vs. −0.93 ± 2.25 kg/m2; p < 0.001). More LA users achieved 5% and 10% weight loss compared to liraglutide users (64.2% vs. 22.7%, 26.6% vs. 4.2%; all p < 0.001). After balancing baseline differences, LA’s benefits remained significant. No adverse events were reported with LA. Conclusions: LA may offer superior weight reduction compared to liraglutide. Future studies should explore LA alone or in combination with liraglutide for obesity management.

To evaluate current studies to establish and compare the efficacy of traditional and laser acupuncture in reducing the signs and symptoms of temporomandibular disorders (TMD). PubMed, Cochrane, Scopus, and Web of Science databases were searched. Clinical, controlled, and randomized trials written in English and having used traditional or laser acupuncture as therapy for TMD and RDC/TMD or DC/TMD as a diagnostic criterion for TMD were included. Six studies that evaluated the intensity of pain and the level of mouth opening of the patients submitted to acupuncture were selected, and all showed improvement. However, similar results were also observed in the groups treated with occlusal splint and placebo acupuncture. Only one study evaluated laser acupuncture and showed a higher proportion of patients with remission of symptoms in the experimental group. The traditional acupuncture seems to relieve the signs and symptoms of TMD, as well as laser acupuncture when associated with occlusal splint. However, more rigorous and high-quality clinical trials are needed. [ABSTRACT FROM AUTHOR]

Previous studies indicated that laser acupuncture (LA) may effectively treat various medical conditions. However, brain responses associated with LA intervention have not been fully investigated. This study is focused on the effect of LA with different energy density (ED) in brain using resting-state functional magnetic resonance imaging (fMRI). We hypothesized that different ED would elicit various brain responses. We enrolled healthy adults participants and selected bilateral PC6 (Neiguan) as the intervention points. LA was applied, respectively, with ED of 0, 7.96, or 23.87 J/cm². Two 500-s resting-state fMRI scans were acquired before and after intervention, respectively. The functional connectivity (FC) was calculated between autonomic nerve system-regulation associated brainstem structures and other brain regions. Compared to other dosages, the FC between rostral ventrolateral medulla and orbitofrontal cortex has more enhanced; the FC between caudal ventrolateral medulla, nucleus of the solitary tract/nucleus ambiguus, and dorsal motor nucleus of the vagus and somatosensory area has more weakened when ED was 23.87 J/cm². Different dosages of LA have demonstrated varied regions of FC changes between regions of interest and other brain areas, which indicated that variations in EDs might influence the clinical efficacy and subsequent impacts through distinct neural pathways within the brain.

The purpose was to compare the effects of diet and exercise and laser interference and maneuver on anthropometric parameters and blood effects of object agents. The study was a randomized controlled longitudinal study. It included 45 adolescents from both sexes who were divided randomly into two groups: one group was treated with low calorie diet and exercise as group A and group B was treated with low calorie diet, exercise, and laser acupuncture. All parameters and blood samples were done before and after the interventions. Group A showed a highly significant reduction post intervention in anthropometric parameters: triceps skin fold thickness (SFT), biceps SFT, subscapular SFT, suprailiac SFT, abdominal SFT, mid-upper arm circumference (MUAC), waist C, and hip C, except for waste/hip (W/H) ratio which showed no significant difference,p > 0.05 and some lipid profiles (cholesterol, LDL) with p < 0.001 Whereas, a significant decrease in TG was observed (p < 0.05). On the other hand, a significant increase in HDL was observed (p < 0.05). Group B (LCD + exercise + LA) showed a highly significant reduction post intervention in anthropometric parameters: triceps SFT, biceps SFT, subscapular SFT, suprailiac SFT, abdominal SFT, MUAC, waist C, and Hip C, except for W/H ratio which showed no significant difference,p > 0.05 and lipid profile: cholesterol, LDL, and TG with (p < 0.001), whereas a highly significant increase in HDL was observed (p < 0.001). The current study revealed a significant difference between group A and group B regarding the percentage of change, where the highest values were found in group B compared to group A, in anthropometric parameters (weight, BMI, subscapular SFT, MUAC, waist circumference) and some lipid profiles (LDL and HDL) with p < 0.05. Laser acupuncture was a safe, easy, and more effective tool with extra effect in management of obesity when added to diet and exercise on anthropometric parameters and lipid profile.

In sports events, the rapid recovery after high-intensity training or sport competition performance is very important for athletes' performance and health. The aim of this study is to evaluate the effect of laser acupuncture and electrical stimulation on the recovery from exercise fatigue, using mice with swimming fatigue as experimental model and the electromyography (EMG) and the Raman spectroscopy of blood as evaluation indicators. Root mean square (RMS) and mean power frequency (MPF) of EMG were analyzed after laser acupuncture and electrical stimulation. The amplitude frequency combined analysis (JASA) showed that the proportion of muscles in the fatigue recovery area of the control group, the laser acupuncture group, the multi-channel laser acupuncture group and the laser combined with electrical stimulation group were 34.78%, 39.13%, 39.13% and 43.48%, respectively. Raman spectroscopy of the mice blood during fatigue recovery showed there is a significant difference between the multi-channel laser acupuncture group and the laser combined with electric stimulation group compared with the recovery period and fatigue period (P < 0. 0 5) at the peak of 997 cm − 1 and the laser combined electrical stimulation group had a statistical difference in the recovery period compared with the fatigue period (P < 0. 0 5) at the peak of 1561 cm − 1 . The results showed that laser acupuncture combined with electrical stimulation was beneficial to fatigue recovery in mice, and had the potential value in sports fatigue recovery.

Acupuncture is the use of a small needle to treat numerous diseases in traditional Chinese medicine. It has been performed on domestic and non-domestic animals as a main, alternate, or multimodal treatment that synergizes with other therapies. Currently, ferrets have become more popular in various countries, including Thailand. Spinal cord injury is one of the common diseases observed in ferrets. According to this presenting ferret, she visited Panalai Veterinary Hospital with posterior paresis after falling from the 8th floor of a building 3 days ago. The physical and neurological examination results showed normal vital signs except for posterior paresis grade 3. The radiograph and abdominal ultrasound results were unremarkable. The differential diagnosis included spinal cord injury from trauma or Spinal Qi/Blood Stagnation and Kidney Qi Deficiency as the traditional Chinese veterinary medicine diagnosis. Laser acupuncture treatment is the primary treatment for this case. Each acupoint was treated with laser therapy (M-Vet, MLS ® ) in Laserpuncture mode. The parameter of laser acupuncture was 611 Hz, intensity 1%, total time 5 seconds, 4.44 J/cm² and repeating 3 times per point. Treatment sessions were twice a week for 3 treatments, then once a week for 9 treatments. As a result, the patient achieved complete recovery in two months after 12 therapies. This successful treatment enabled the patient to regain the ability to walk normally, even on slippery surfaces. This case report describes the effectiveness of laser acupuncture treatment in a ferret with posterior paresis resulting from a spinal cord injury. [ABSTRACT FROM AUTHOR]

Background: “Corona virus disease 2019 or COVID-19” causes significant respiratory, internal, physical, and psychological problems affecting quality of life [QoL]. Pedometer-based walking and laser acupuncture may improve the health of patients with COVID-19 but more research is needed.Aim of the Work: This study aimed to investigate the effect of pedometer-based walking alone or combined with laser acupuncture on QoL in post-COVID patients.Patients and Methods: Sixty post-COVID-19 patients of both genders with ages ranging from 35-48 years old were recruited from the Chest-disease outpatient clinic of El Khankah Central Hospital and divided equally to Group A & B. Group A underwent laser acupuncture 3 session per week, with pedometer-based walking [3000 steps] for 4 weeks. Patients of Group B received daily pedometer-based walking [3000 steps] for 4 weeks. They were evaluated regarding C-reactive protein, white blood cells, lymphocytes, neutrophils, six-minute walk test, fatigue assessment, and short form 36.Results: There were significant improvements in all outcomes [P-value < 0.05] after both treatments that were significantly higher in group A.Conclusion: Combining laser acupuncture and pedometer-based walking is better than pedometer-based walking alone in improving QoL in post COVID-19 patients. However, both treatments were effective. Program of management of patients with post COVID-19 syndrome should include pedometer-based walking and laser acupuncture.

Currently, the prevention, assessment, and management of procedural pain in neonates continues to challenge clinicians and researchers. Objective. To investigate the analgesic effect of low-level laser therapy (LLLT) during heel lance compared to breast milk (BM) feeding in healthy term neonates. In this randomized controlled trial, healthy term neonates who underwent heel lance were randomly assigned to an LLLT or a BM group. The LLLT group received laser therapy to the heel lance site for 20 s before heel lance. The BM group received 5 mL expressed BM via a syringe before heel lance. The primary outcomes were behavioral responses. The secondary outcomes were physiological responses and levels of salivary cortisol and α-amylase. A total of 125 neonates were included, of whom 55 in the LLLT group and 59 in the BM group completed the study. There were no significant differences in latency to first cry and cry duration between the two groups. The squeeze time was significantly shorter in the LLLT group than in the BM group (p = 0.047). There were no significant differences in pain scores, heart rate, respiratory rate, oxygen saturation, and blood pressure before and after heel lance between the two groups. There were no significant differences in salivary cortisol and α-amylase levels in the LLLT group before and after heel lance; however, the differences were significant in the BM group. These findings suggest that the analgesic effect of LLLT is similar to that of BM during heel lance in healthy term neonates. LLLT has potential as an analgesic treatment.

Carpal tunnel syndrome (CTS) is disease that gives burdens for many countries, with a few choices for the management such as drugs or surgery, each has side effects that decrease the quality of life. Acupuncture is proven to be an effective treatment for pain and can restore nerve functions, and laser acupuncture is one of the modalities. This study aims to assess the effectiveness of laser acupuncture with total sample of 3 patients (6 wrists) mostly with tingling sensations and the outcomes are Boston questionnaire (BCTQ), visual analogue scale (VAS), Tinel sign, Phalen sign, and parameters of nerve conduction study (NCS). Acupuncture points used here are PC6, PC7, EXUE9, and LI4. The results show a decrease in NCS grades for 3 wrists, all wrists have BCTQ score improvements, a decrease in VAS, but no significant improvement in Tinel and Phalen signs. It is concluded that laser acupuncture can be used as a treatment option for the management of carpal tunnel syndrome.

Background: Peripheral artery disease (PAD) receives little attention despite its clinical consequences. Intermittent claudication is the most disturbing symptom of the disease resulting in marked limitations to functional walking performance. Treadmill walking exercise is the first-line non-pharmacological treatment in PAD; however, older patients may be unable to exercise because of the functional disability of the disease itself or deconditioning. Objective: In an attempt to seek an alternative intervention, this study aimed to assess the effect of laser acupuncture on patient-reported claudication symptoms and walk performance in PAD. Methods: Thirty male patients with PAD were assigned randomly to a control group ([Formula: see text], [Formula: see text] years old, [Formula: see text][Formula: see text]kg/m2) or a study group ([Formula: see text], [Formula: see text] years old, [Formula: see text][Formula: see text]kg/m2). Inclusion criteria were mild-to-moderate PAD, Fontaine stage II, unilateral or bilateral claudications, and older men. Exclusion criteria were asymptomatic PAD, resting pain, severe or critical limb ischemia, ischemic ulcers, and patients contraindicated for laser therapy. Both groups received pharmacological treatment, but only the study group received gallium aluminum arsenide (GaAlAs) laser therapy at nine acupuncture points, namely, Liver 2 (LV2), Stomach 41 (ST41), Urinary bladder 40 (UB40), UB60, UB61, Gall bladder 30 (GB30), GB34, GB38, and GB40 for 2 days/week and five consecutive weeks. A pen-type laser device was used at a wavelength of [Formula: see text][Formula: see text]nm, with a power output of [Formula: see text][Formula: see text]mW, a spot size of 0.08[Formula: see text]cm2, and an energy density of 2[Formula: see text]J/cm2, for 60[Formula: see text]s/point. The Edinburgh Claudication Questionnaire (ECQ) and the 6-min walk distance (6-MWD) were the endpoints of the study. The McNemar–Bowker Test and Generalized Estimating Equations Ordinal Logistic Regression Model were used for the within- and between-group statistical analyses of the categorical data of ECQ, respectively; and a mixed model MANOVA was used for the within- and between-group analyses of the 6-MWD data. Results: There was a significant improvement in patients’ response to ECQ only in the study group compared to the baseline ([Formula: see text]) and the controls ([Formula: see text]) after the intervention. The 6-MWD increased significantly in the study group compared to the baseline ([Formula: see text][Formula: see text]m versus [Formula: see text][Formula: see text]m, [Formula: see text]). Conclusion: The GaAlAs laser acupuncture applied at selected acupoints may be a promising intervention complementary to drug therapy that could help relieve claudication symptoms and improve physical functional performance in older men with PAD (Fontaine stage II). Trials were conducted under the Trial Registration No. PACTR201912698539774.

Laser acupuncture can be used to treat neurosensory alterations and motor disorders caused by dental treatments. This study aimed to review the existing literature on the effects of laser acupuncture on neuropathies in the context of dentistry and to search for treatment modalities in which this technique is used. This systematic review was conducted in accordance with the Cochrane Collaboration guidelines and the PICOS strategy. Randomized clinical trials that evaluated laser acupuncture as a primary intervention for facial neuropathy were included. We searched the database for relevant studies and manually searched the gray literature until April 2022, and finally included four studies. The study was considered eligible if it included patients with paresthesia, facial paralysis, or neuralgia, neuropathies within dentistry, and referred to the application of laser acupuncture as a treatment method. The risk of bias was assessed using the RoB 2 tool. It was observed that the recommended wavelengths ranged from 790 nm to 810 nm, with a frequency of at least two applications per week, and to a greater or lesser degree, all evaluated studies obtained an improvement in sensory or motor recovery of the facial nerves. The use of laser acupuncture presented itself as a viable alternative in dentistry for the treatment of paresthesia and facial paralysis due to its therapeutic potential in neuropathic treatment (CRD42022344339).

Functional chronic constipation (FCC) is a disorder caused by low fiber consumption, lack of fluid intake, lack of mobility, or side effects of medications. The objective of this study was to compare the effects of laser acupuncture and the commonly used osmotic laxative, lactulose (as the control), both combined with behavioral therapy and dietary modification, on children with FCC in a randomized controlled trial (RCT). Forty children were randomly chosen, aged 5–15 years with FCC, and randomized into two equal groups (gender ratio (50% male; 50% female), mean ± SD weight (24.2 ± 6.27 kg and 25.7 ± 7.47 kg for groups A and B, respectively)). Study group (group A): used laser acupuncture (650 nm), 30 mW, 0.15 cm2 spot size, 90 s per acupuncture point (ST25, ST36, ST37, BL25, and LI11). Control group (group B): lactulose syrup (1 to 3 mL/kg/day) orally, in divided doses 3 times weekly for 4 weeks, and behavioral training for both groups. Evaluations were conducted before and after the study to assess the efficacy of the therapy. Median value frequency significantly increased in groups A and B post-treatment (4 (6.75–3) and 3 (3.75–2), respectively) compared to pre-treatment (2 (2–1) and 2 (2–0.25), respectively) (p = 0.0001), in favor of group A (p = 0.01). Significant improvement of stool consistency according to Bristol stool scale (BSS) in groups A and B (p = 0.0001), (p = 0.002) respectively in favor of group A (p = 0.03). T-test, Fisher, and Wilcoxon signed rank tests were conducted to compare groups. Non-invasive, painless laser acupuncture therapy can be considered as an alternative therapy for patients with FCC.

One of the most common diseases that is the reason of severe neurological disability is Cerebral Palsy (CP). CP worldwide prevalence is average 1-4 per 1000 live births. The purpose of study was to confirm the impact of laser acupuncture therapy in improvement of immunity indices in children with spastic CP by rising NK cells count. From the pediatric outpatient clinic of the National Institute of Laser Enhanced Sciences (NILES) and the physical therapy outpatient clinic at Benha Fever Hospital, 40 children with spastic CP aged 1 to 3 years of both genders were recruited. They were split into two groups of equal number at random: The physical therapy sessions for Group A (the control group) consisted of one hour each session, three times each week, for a total of 12 weeks. In addition to their regular physical treatment, participants in Group B (the study group) also underwent 780 nm Diode laser acupuncture with an output power of 50 mw three times weekly for a total of 12 sessions. All children in both groups had their NK cells (CD16 CD56) measured by flow cytometry using “BD Facscalibur” with two different colors before and after treatment. Statistical tests were performed on the data. Counts of NK cells (CD16, CD56) differed significantly between group A and group B after treatment, with group B having a higher total. The results of this study showed that the number of NK cells in the children with spastic CP increased after they had laser acupuncture treatment. [ABSTRACT FROM AUTHOR]

Introduction: The coronavirus disease (COVID-19) was extended to the entire population in China and around the world, and its mortality rate was about 3.4%. The impact of laser therapy on chronic respiratory diseases has been shown in previous studies. This study was aimed at examining the effects of laser acupuncture (LA) on patients with severe COVID-19. Methods: In the present study, 60 patients with a positive reverse transcription-polymerase chain reaction (RT-PCR) test were assigned to the intervention and control groups (30 patients in each group). The intervention group was treated with LA, that is, laser light with low energy on acupuncture points, once a day for five consecutive days. Results: The participants' mean age in the intervention and control groups was 48.96 ± 12.65 and 53.16 ± 12.28 respectively; 70% of the patients were male and 30% of them were female. IL6 had a significant reduction in the intervention group (P value = 0.038) in comparison with the control group (P value = 0.535). Furthermore, the mean admission time in the control group was significantly higher than that in the intervention group (P value = 0.047). However, the mortality rate in the intervention group was zero, but three patients in the control group died. Conclusion: Our study showed that LA can be used as supportive therapy for routine treatment in patients with severe COVID-19. Moreover, due to LA safety and it's low cost, it could be recommended as an adjuvant to conventional therapy in patients interested in treating their disease with such a method.

Introduction: The objective of this study was to assess the effectiveness and safety of photobiomodulation (PBM) in the treatment of male infertility. Methods: We searched Google Scholar, PubMed, and the reference sections of relevant papers published from January 1, 2000 to September 23, 2022. We retrieved all publications related to the impact of PBM on male infertility. After reviewing the titles, abstracts, and full texts, we included fifteen papers in the research. The studies involved 477 semen samples (in vitro studies) and 70 male participants (randomized clinical trials). Results: All 14 in vitro studies that evaluated effectiveness reported that PBM was successful in increasing the proportion of progressive sperms in semen samples. Various methods were used to evaluate the safety. One study with a sample size of 58 concluded that PBM was not a safe treatment, whereas the other ten studies confirmed its safety. Only one clinical trial evaluated the effect of laser acupuncture on male infertility and found improvements in sperm progressive motility without any serious adverse effects. Conclusion: All 15 studies evaluating effectiveness reported that the low-level laser was effective for increasing the proportion of progressive sperm in semen samples and that it was safe to use. However, due to the heterogeneity of population characteristics, source characteristics, duration of exposure, sample size, and instruments for measuring safety and efficacy, we cannot conclude that the positive results obtained from the reviewed studies are solely attributable to the low-level laser on the sperm samples.

• Electroacupuncture provides superior benefits for improving stress urinary incontinence in women compared with sham electroacupuncture. • Electroacupuncture combined with pelvic floor muscle training is beneficial for improving stress urinary incontinence in women compared with medications. • Body, electro,- and laser acupuncture are effective for improving the number of urge accidents in women with overactive bladder however, the evidence for these interventions is limited to single studies. Evidence regarding the efficacy of various forms of acupuncture for the treatment of urinary incontinence (UI) in women is outdated and inconclusive. This review aims to determine the efficacy of different forms of acupuncture for the treatment of UI in women. Multiple databases were searched from inception to June 2020. Randomized controlled trials that compared various forms of acupuncture to control were included. Ten trials were included in this review. The pooled analysis demonstrated that an increased proportion of women with stress UI (SUI) reported fewer UI episodes (1.73 [95% CI 1.46, 2.04]; p < 0.00001) in the electroacupuncture group than in the sham group. The meta-analysis also revealed a significantly increased number of women who reported the complete cure of SUI in the electroacupuncture combined with pelvic floor muscle training group than in the medication group (RR 2.67 [95% CI 1.51, 4.71]; p = 0.0007). Body and laser acupuncture caused significant decreases in the number of urge accidents (-2.70 [95% CI -4.86, -0.54]; p = 0.01) and the occurrence of urgency symptoms (-3.60[95% CI -5.34, -1.86]; p < 0.0001), compared with sham acupuncture. Based on the findings of this review, electroacupuncture may be able to improve SUI in women in clinical settings. This review also identified evidence supporting the use of body, electro,- and laser acupuncture for the treatment of urge UI; however, these results were obtained from single studies, and further research remains necessary to confirm the effects of these interventions on the treatment of urge UI in women.

Laser acupuncture (LA) has been more applicated in the clinical practice with good responses, but the dosage and parameter settings are still inconsistent with the arguments. This study is focused on the effect of LA on heart rate variability (HRV) with different energy density (ED). Based on the Arndt–Schulz law, we hypothesized that the effective range should fall within 0.01 to 10 J/cm2 of ED, and settings above 10 J/cm2 would perform opposite or inhibitory results. We recruited healthy adults in both sexes as subjects and choose bilateral PC6 (Neiguan) as the intervention points to observe the HRV indexes changes by an external wrist autonomic nerve system (ANS) watch on the left forearm. The data from the ANS watch, including heart rate, blood pressure, and ANS activity indexes, such as low frequency (LF), high frequency (HF), LF%, HF%, LF/HF ratio, and so on, were analyzed by the one-way ANOVA method to test the possible effect. In this study, every subject received all three different EDs of LA in a randomized order. After analyzing the data of 20 subjects, the index of HF% was upward and LF/HF ratio was downward when the ED was 7.96 J/cm2. Otherwise, the strongest ED 23.87 J/cm2 performed the opposite reaction. Appropriately, LA intervention could affect the ANS activities, with the tendency to increase the ratio of parasympathetic and decrease the ratio of sympathetic nerve system activities with statistically significant results, and different ED interventions are consistent with Arndt–Schulz law with opposite performance below and above 10 J/cm2.

Abstract Background Nonspecific neck pain is a multifactorial and very common condition in adult individuals, traditional acupuncture (TA) and laser acupuncture (LA) may be treatment options for certain individuals in such a condition. However, no reports were found in the literature comparing the effectiveness of TA and LA in cases of chronic nonspecific neck pain. Therefore, the aim of the present study is to investigate the effectiveness of TA and LA therapies in individuals with chronic nonspecific neck pain, noting which one is more efficient for this condition. The result of this research will have direct implications for pain management and, consequently, may benefit individuals suffering from nonspecific chronic neck pain. Methods/design This will be a controlled and randomized clinical trial. Eighty-four individuals will be recruited and distributed equally and randomly into 3 groups: TA (which will receive the acupuncture treatment with needles), LA (which will receive the laser acupuncture treatment), and Sham (who will receive the placebo intervention). The acupuncture points (Tianzhu, Fengchi, Jianjing, and Jianzhongshu) will be stimulated bilaterally. The primary outcome will be pain intensity, determined using the Numerical Rating Scale. The secondary outcomes will be pressure pain threshold, temporal summation of pain, conditioned pain modulation, use of analgesic medicines after treatment, and the global perceived effect scale. The assessments will be performed immediately before and after the treatment, which will be a single session, at the follow-up and 1 month after the end of the treatments; evaluation will be made of the pain intensity and the global perceived effect. Statistical analysis of the data obtained will consider a significance level of p < 0.05. Discussion This study will provide evidence concerning the effects of LA treatment, in comparison with TA and sham intervention, leading to benefits for individuals suffering from chronic nonspecific neck pain.

Quality of life was reported using the Short Form (SF)-12v2. Results: The experimental group showed a significant decrease in heroin use (p

BackgroundWe aim to obtain clinical trial data regarding the safety, efficacy, and usefulness of invasive laser acupuncture (ILA) for non-specific chronic low back pain (NSCLBP) through a randomized placebo-controlled trial.MethodsOur clinical trial will be an assessor- and patient-blinded, prospective, parallel-arm, multi-center, randomized placebo-controlled clinical trial. One hundred and six participants with NSCLBP will be allocated evenly to the 650 ILA or control group. All participants will receive education on exercise and self-management. The 650 ILA group will undergo 650 nm ILA for 10 min, and the control group will undergo sham ILA for 10 min per visit, twice a week for 4 weeks, at bilateral GB30, BL23, BL24, and BL25. The primary outcome will be the proportion of responders (≥30% reduction in pain visual analogue scale [VAS] without increased use of painkillers) at 3 days after the intervention ends. The secondary outcomes will include changes in the scores of the VAS, European Quality of Life Five Dimension Five Level scale, and Korean version of the Oswestry Disability Index at 3 days after the intervention ends and 8 weeks after the intervention ends.DiscussionsThe results of our study will provide clinical evidence concerning the safety and efficacy of 650 nm ILA for the management of NSCLBP.Clinical trial registrationhttps://cris.nih.go.kr/cris/search/detailSearch.do?search_lang=E&focus=reset_12&search_page=M&pageSize=10&page=undefined&seq=21591&status=5&seq_group=21591, identifier KCT0007167.

This study aims to evaluate the therapeutic effects of laser acupuncture (LA) on articular cartilage degradation at the early stage of postmenopausal osteoarthritis (PMOA) by an ultrasound biomicroscopic technology. Twenty-one healthy female Sprague-Dawley rats were randomly and evenly divided into three groups - sham, ovariectomized (OVX) and OVX ​+ ​LA groups. Only the peri-ovarian fatty tissue of the sham rats was exteriorized. The animals in the OVX and OVX ​+ ​LA groups underwent bilateral ovariectomy to create a menopause model. On day 8 after the ovariectomy, the 2-week LA therapy at acupoints Guanyuan (CV-4), Sanyinjiao (SP-6), and Zusanli (ST-36) was performed in the OVX ​+ ​LA group, while the sham and OVX groups had a sham treatment. All the animals were sacrificed on day 22. The cartilage tissues in the left knee joint were examined by ultrasound and histology. Compared with the sham group, the significantly degenerate alterations (p ​

Background: Laser acupuncture regulates energy flow and restores body fluid metabolism. Objective: To evaluate the effects of the laser acupuncture protocol (LAP) on hepatic and renal metabolism in sedentary people. Methods: Longitudinal, double-blind, and randomized clinical trial with 29 participants, adults, both sexes, sedentary, without pre-existing metabolic diseases, subdivided into control and laser groups. Based on the STandards for Reporting Interventions in Clinical Trials of Acupuncture 2010 guidelines, 10 laser applications (660 nm ±10 nm wavelength, 100 mW power. The irradiation tip has a diameter of 5 mm, which corresponds to an area of 0.19 cm 2 , totaling a power density of 0.52 W/cm 2 and considering the irradiation time of 90 s, the energy density applied was 47.3 J/cm 2 ) were performed on the acupoints of metabolic functions (LR3, SP6, ST36, and LI4) and blood samples were collected for fasting glycemia, lipid profile (HDL, LDL, total cholesterol, and triglycerides), liver function (AST/GOT and ALT/GPT), and renal function (serum creatinine and urea). A repeated measures analysis of variance (ANOVA) with Bonferroni corrected post hoc comparisons was applied to compare statistical differences between groups and times, adopting p < 0.05 as the null hypothesis. Results: The laser stimulated changes in serum lipid profile values and renal and hepatic functions. There was a significant ( p = 0.014) reduction in LDL ("bad" cholesterol) from 105.75 ± 32.83 pre- to 84.32 ± 18.38 mg/dL postintervention, associated with cardioprotective function. Positive significant ( p = 0.035) impacts were also observed in the reduction of creatinine (0.86 ± 0.12 mg/dL to 0.75 ± 0.12 mg/dL) and the enzyme AST/GOT (33.73 ± 12.95 U/L to 20.80 ± 4.99 U/L, p = 0.002). Conclusion: LAP applied to basal metabolism acupoints promoted positive metabolic changes in the lipid profile (LDL), and in main markers of the liver (AST/GOT) and kidney (creatinine) functions, contributing to risk control of cardiovascular diseases.

Introduction: Neck pain is the fourth leading cause of disability worldwide. This study aims to investigate the effects of Electro Acupuncture (EA) versus Laser Acupuncture (LA) on symptoms of women with chronic cervical myofascial pain syndrome. Materials and Methods: This is a single-blind randomized controlled clinical trial. Thirty women with chronic cervical myofascial pain syndrome were randomly divided into three groups: EA, LA, and sham. The EA group received electrical stimulation through needles at standard acupuncture points, while the LA group received low-intensity laser irradiation at the same points. The passive laser probe was applied for the sham group. The outcome measures were neck pain pressure threshold, neck pain severity, neck disability, and cervical range of motion Results: The pain severity and disability were significantly lower in the EA group than in the other two groups. The neck range of motion (cervical lateral flexion and rotation) and pain pressure threshold increased significantly in the EA group immediately and one week after the intervention. Conclusion: Both EA and LA interventions may be effective in alleviating the symptoms of cervical myofascial pain syndrome, but the EA can be more effective in reducing neck pain and disability in women with cervical myofascial pain syndrome.

Background: The efficacy of different forms of acupuncture for the treatment of nocturnal enuresis in children is not known.Objective: To determine the efficacy of different forms of acupuncture, such as manual acupuncture, laser/electroacupuncture, acupoint injection, and moxibustion, for the treatment of nocturnal enuresis.Methods: A literature search was conducted on Medline, EMBASE, Web of Science, CINAHL, PubMed, Physiotherapy Evidence Database, and Scopus from database inception to September 2020. The Cochrane risk of bias tool was utilised to evaluate the risk of bias in each included study. The quality of the evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation tool.Results: Thirteen trials (n = 890) were included. Meta-analyses revealed significantly greater numbers of children reporting improved nocturnal enuresis in the moxibustion (p = 0.004), acupoint injection (p = 0.020), and laser acupuncture (p = 0.001) groups than in the control groups. Meta-analyses showed no significant differences in the numbers of children reporting the complete cure of nocturnal enuresis between laser acupuncture and desmopressin (p = 0.57).Conclusions: The review identified moxibustion, acupoint injections, and laser acupuncture as effective treatments for nocturnal enuresis in children. However, the evidence for these interventions is limited and of very-low-grade quality. The effects of laser acupuncture compared with desmopressin remain inconclusive. [ABSTRACT FROM AUTHOR]

The primary outcome was the treatment efficacy for pain. The secondary outcomes included the comparison of disability, functional impairment, and dropout rate between LA and sham treatment, as well as the effect of sham treatment for pain. The results from included studies were synthesized with the random effects model.Results: In total, 20 articles comprising 568 patients receiving LA and 534 patients receiving sham treatment were included in the current study. Our analysis showed LA significantly reduced pain (g=0.88, 95% confidence interval [CI]=0.35 to 1.42, p=0.001), disability (g=0.68, 95% CI=0.29 to 1.08, p< 0.001), and functional impairment (g=0.67, 95% CI=0.32 to 1.03, p< 0.001). Through meta-regression analysis, we found these effects were not moderated by mean age, the percentage of females, or treatment duration. Additionally, there was no significant difference between the two groups in dropout rate (risk ratio=0.73, p=0.08), and the sham treatment significantly reduced only pain intensity (g=0.54, 95% CI=0.32 to 0.77, p< 0.001).Conclusion: Our findings supported that LA significantly reduced pain, disability, and functional impairment in patients with musculoskeletal disorders. Further researches are required to determine the optimal therapeutic parameters and the suitable patients for receiving LA.Protocol Registration: CRD42020190919.Keywords: laser acupuncture, meta-analysis, pain, randomized controlled trial, traditional Chinese medicine

Introduction: Neck pain is the fourth leading cause of disability worldwide. This study aims to investigate the effects of Electro Acupuncture (EA) versus Laser Acupuncture (LA) on symptoms of women with chronic cervical myofascial pain syndrome. Materials and Methods: This is a single-blind randomized controlled clinical trial. Thirty women with chronic cervical myofascial pain syndrome were randomly divided into three groups: EA, LA, and sham. The EA group received electrical stimulation through needles at standard acupuncture points, while the LA group received low-intensity laser irradiation at the same points. The passive laser probe was applied for the sham group. The outcome measures were neck pain pressure threshold, neck pain severity, neck disability, and cervical range of motion Results: The pain severity and disability were significantly lower in the EA group than in the other two groups. The neck range of motion (cervical lateral flexion and rotation) and pain pressure threshold increased significantly in the EA group immediately and one week after the intervention. Conclusion: Both EA and LA interventions may be effective in alleviating the symptoms of cervical myofascial pain syndrome, but the EA can be more effective in reducing neck pain and disability in women with cervical myofascial pain syndrome.

Low-level laser therapy including laser acupuncture has been widely used for non-specific chronic low back pain in primary Korean medical clinics. However, there is no critically appraised data regarding which treatment conditions are most effective. A systematic review and meta-analysis was conducted to determine effective treatment conditions using 12 databases (PubMed, Ovid, CENTRAL, KoreaMed, KMBASE, KISS, NDSL, KISTI, OASIS, CNKI, CiNII, and J-STAGE). There were 1,019 studies retrieved and 13 studies included in this review. It was determined that when the power output was ≥ 50 mW, the beam size was increased to ≥ 1 cm2, the energy dose was increased to ≥ 4 J per point, the treatment interval was increased to ≥ 3 times a week, and the number of treatment sessions was increased to ≥ 10 treatments, these conditions appeared to increased treatment effectiveness.

Background : Diabetes mellitus (DM) is a chronic metabolic disease characterized by increased blood sugar levels. The current management of DM to date has a target of controlling blood glucose, but the therapy cannot be separated from long-term drug side effects. Acupuncture can be an option as an adjunct therapy for DM. Objectives: The purpose of this study was to compare the effectiveness between manual acupuncture and laser acupuncture. Methods : This study was a randomized control experimental study with a pretest and posttest design using 24 male Sprague-Dawley rats divided into 4 groups: a normal group, a diabetes group, an acupuncture group, and a laser group. Manual acupuncture and laser acupuncture were performed 6 times in two weeks. Fasting blood glucose (FBG) levels, the cell density of Langerhans islets, and side effects were assessed and compared among the 4 groups. Results : The highest mean cell density of Langerhans islets was found in the laser and acupuncture group, and the lowest was found in the diabetes group. In the post hoc analysis, the normal, acupuncture, and the laser groups had a significantly higher mean cell density than the diabetes group. The lowest mean FBG level was in the laser group, followed by the acupuncture group, and the highest was in the diabetes group, but this difference was not significant. There were no serious side effects from the use of manual acupuncture or laser acupuncture. Conclusion : Both manual acupuncture and laser acupuncture can improve the histological findings of Langerhans islets in type 2 diabetic rats, and both are safe to use.

Background: Nonspecific neck pain is a multifactorial and very common condition in adult individuals, traditional acupuncture (TA) and laser acupuncture (LA) may be treatment options for certain individuals in such a condition. However, no reports were found in the literature comparing the effectiveness of TA and LA in cases of chronic nonspecific neck pain. Therefore, the aim of the present study is to investigate the effectiveness of TA and LA therapies in individuals with chronic nonspecific neck pain, noting which one is more efficient for this condition. The result of this research will have direct implications for pain management and, consequently, may benefit individuals suffering from nonspecific chronic neck pain.Methods/design: This will be a controlled and randomized clinical trial. Eighty-four individuals will be recruited and distributed equally and randomly into 3 groups: TA (which will receive the acupuncture treatment with needles), LA (which will receive the laser acupuncture treatment), and Sham (who will receive the placebo intervention). The acupuncture points (Tianzhu, Fengchi, Jianjing, and Jianzhongshu) will be stimulated bilaterally. The primary outcome will be pain intensity, determined using the Numerical Rating Scale. The secondary outcomes will be pressure pain threshold, temporal summation of pain, conditioned pain modulation, use of analgesic medicines after treatment, and the global perceived effect scale. The assessments will be performed immediately before and after the treatment, which will be a single session, at the follow-up and 1 month after the end of the treatments; evaluation will be made of the pain intensity and the global perceived effect. Statistical analysis of the data obtained will consider a significance level of p < 0.05.Discussion: This study will provide evidence concerning the effects of LA treatment, in comparison with TA and sham intervention, leading to benefits for individuals suffering from chronic nonspecific neck pain.Trial Registration: Brazilian Registry of Clinical Trials - ReBEC RBR-7vbw5gd . Date of registration: August 06th, 2021.
