Morel-Lavallée lesions (MLLs) result from high-energy trauma causing separation of subcutaneous tissue from the underlying tissue, most commonly in the gluteal region or thigh.We report the case of a woman in her 40s with a fluctuant collection of the cervico-thoracic region following trauma. Further imaging identified an MLL. An orthoplastic approach resulted in non-operative management with a spinal brace. Three months from initial injury, the lesion completely resolved. She was symptom free at final follow-up and discharged.We present the only recorded case of MLL developing in the cervico-thoracic region. Management posed difficultly as no literature currently exists. We demonstrated conservative management for cervico-thoracic MLL can be effective.We have described the first documented case of cervico-thoracic MLL. MLL is not exclusive to pelvic injuries and can develop in the cervico-thoracic region. We have shown conservative management is a viable treatment of atypical MLL., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023. No commercial re-use.

Abstract: Basal cell carcinomas and melanoma are common cutaneous malignancies. However, the development of a basomelanocytic tumor that simultaneously includes elements of melanoma and basal cell carcinoma is extremely rare. We present the case of an 84-year-old man who presented with a nonpigmented, nonulcerated pink nodule of his left upper back and discuss the current management recommendations for basomelanocytic tumors., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Schwannoma is a benign tumour of Schwann cells originating from myelin sheath of axons of the nerves. It is usually seen in the vestibular region, very rarely found in extremity regions. Schwannomas are termed 'Giant' when they measure more than five centimetres in a minimum of one dimension. Giant schwannomas in the foot and ankle region are extremely uncommon. Only eight cases of such a condition are reported. This is a case report of a giant schwannoma found arising from the superficial peroneal nerve in the dorsolateral aspect of the foot. This swelling was excised completely and the diagnosis was confirmed by histopathology., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Abstract: Necrotizing infundibular crystalline folliculitis (NICF) is a rare distinct entity that was introduced in 1999. It typically presents with numerous eruptive waxy papules on the forehead and/or the upper back in adults in their fifth to seventh decade of life. The pathogenesis is unknown to date, but yeast and bacterial infection of the follicular ostia seems to contribute to the development. More recently, NICF has occasionally been observed as a side effect of targeted antitumoral therapy. Histopathologically, NICF is characterized by dilated follicular ostia filled with pale filamentous and birefringent material enclosed by parakeratotic columns of the epidermis and accompanied by a mild superficial inflammatory infiltrate of the dermis. This case report is about a 58-year-old male patient presenting with multiple eruptive keratotic papules on his forehead. Histopathology revealed all classic features of NICF. The case represents a classic example of NICF and is compared with previously published cases that are comprehensively summarized in this article., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a “work of the United States Government” for which copyright protection under Title 17 of the United States Code is not available.

Annular lichen planus is a rare clinical variant of the lichen planus presenting with round-oval, red to brown macules and plaques with no central atrophy and slightly raised, nonscaly borders. Histopathological features are indistinguishable from typical lichen planus. Given that the accurate diagnosis relies on both the clinical presentation and typical histological features, it is important to be aware of the clinical spectrum of lichen planus.

Ligamentum flavum hypertrophy (HLF) is the most important component of lumbar spinal canal stenosis (LSCS). Analysis of hypertrophied ligamentum flavum (HLF) samples from patients with LSCS can be an important que. The current study analyzed the surgical samples of HLF samples in patients with LCSC using quantitative and qualitative high performance-liquid chromatography and mass spectrometry. We collected ligamentum flavum (LF) tissue from twelve patients with LSCS and from four patients with lumbar disk herniation (LDH). We defined LF from LSCS patients as HLF and that from LDH patients as non-hypertrophied ligamentum flavum (NHLF). Total lipids were extracted from the LF samples and evaluated for quantity and quality using liquid chromatography and mass spectrometry. The total lipid amount of the HLF group was 3.6 times higher than that of the NHLF group. Phosphatidylcholines (PCs), ceramides (Cers), O-acyl-ω-hydroxy fatty acids (OAHFAs), and triglycerides (TGs) in the HLF group were more than 32 times higher than those of the NHLF group. PC(26:0)+H+, PC(25:0)+H+, and PC(23:0)+H+ increased in all patients in the HLF group compared to the NHLF group. The thickness of the LF correlated significantly with PC(26:0)+H+ in HLF. We identified the enriched specific PCs, Cers, OAHFAs, and TGs in HLF., (© 2021. The Author(s).)

The keystone perforator island flap (KPIF) is popular in reconstructive surgery. However, despite its versatility, its biomechanical effectiveness is unclear. We present our experience of KPIF reconstruction in the human back and evaluate the tension-reducing effect of the KPIF. Between September 2019 and August 2020, 17 patients (51.82 ± 14.72 years) underwent KPIF reconstruction for back defects. In all cases, we measured wound tension at the defect and donor sites before and after KPIF reconstruction using a tensiometer. All defects occurred after complete excision of complicated epidermoid cysts and debridement of surrounding tissues. The defects were successfully covered with Type IIA KPIFs. All flaps survived, and there were no significant postoperative complications. The mean "tension change at the defect after Type I KPIF" and "tension change at the defect after Type II KPIF" were - 2.97 ± 0.22 N and - 5.59 ± 0.41 N, respectively, (P < 0.001). The mean "rate of tension change at the defect after Type I KPIF" and "rate of tension change at the defect after Type II KPIF" were - 36.54 ± 1.89% and - 67.98 ± 1.63%, respectively, (P < 0.001). Our findings confirm the stepwise tension-reducing effect of KPIF and clarify the biomechanics of this flap., (© 2021. The Author(s).)

The outcomes of patients with metastatic melanoma (MM) have significantly improved after the introduction of BRAF-specific inhibitors. Herein is reported a patient with MM and non-V600-BRAF mutation who responded to iBRAF/iMEK therapy. In July 2014, a 63-year-old man presented with a 4.1mm-thick V600E-BRAF wild type melanoma on the back. Metastases were identified in one sentinel node and two of 11 subsequently excised lymph nodes, with no signs of distant metastatic disease. In September 2017, lung metastasis was observed and pembrolizumab was started. Progressive disease was apparent at cycle 10 and therapy was switched to ipilimumab. After four cycles, an asymmetric response was observed. In November 2017, next generation sequencing genomic profiling disclosed a rare L597K-BRAF mutation and vemurafenib plus cobimetinib therapy was initiated in January 2018. Seven days after treatment start, a remarkable clinical improvement was observed. In April 2018, the patient achieved partial response, which was sustained until October 2018. Cases of patients with non-V600-BRAF mutations responding to iBRAF/iMEK therapy have been reported over the last years. To the best of our knowledge, this is the first case reporting response to combined iBRAF/iMEK therapy in a patient with metastatic melanoma harboring L597K mutation.

Subcutaneous fat necrosis of the newborn is a rare lobular panniculitis. It is characteristic of term or post-term neonates with a history of perinatal compromise or maternal gestational pathology. The cutaneous manifestations consist of erythematous and indurated subcutaneous plaques and nodules located over the dorsal region and the shoulders. Diagnosis is clinical and pathological. Histopathological findings include lobular panniculitis with a lymphohistiocytic inflammatory infiltrate with few neutrophils, fatty necrosis, deposition of radial needle-shaped crystals in the adipocytes, and possible calcification and hemorrhage. The cutaneous ultrasound shows hyperechoic and avascular subcutaneous cellular tissue and acoustic shadows may appear corresponding to calcifications. The clinical differential diagnosis includes sclerema neonatorum and post-corticosteroid panniculitis. Histologically crystal-forming panniculitis conditions are in the differential diagnosis. The disease is usually self-limited but complications such as hypercalcemia, hypoglycemia, hypertriglyceridemia, thrombocytopenia, and anemia may occur. Complications should be ruled out and treated at diagnosis and during follow-up. The most important complication is hypercalcemia.La necrosis grasa subcutánea neonatal es una paniculitis lobulillar infrecuente. Es característica de neonatos a término o postérmino con antecedentes de sufrimiento perinatal o patología gestacional materna. Las manifestaciones cutáneas consisten en placas y nódulos subcutáneos eritematosos e indurados localizados preferentemente en la región dorsal y los hombros. El diagnóstico es clínicopatológico. Los hallazgos histopatológicos comprenden una paniculitis lobulillar con un infiltrado inflamatorio linfohistiocitario con escasos neutrófilos, necrosis grasa, depósito de cristales radiados en los adipocitos y posibles focos de calcificación y hemorragia. En la ecografía cutánea se observa hiperecogenicidad y avascularización del tejido celular subcutáneo y pueden aparecer sombras acústicas posteriores que se correspondencon calcificaciones. El diagnóstico diferencial clínico se debe realizar con el escleredema neonatorum y la paniculitis postesteroidea, e histológicamente con las paniculitis con formación de cristales. La enfermedad suele ser autolimitada pero pueden aparecer complicaciones como la hipercalcemia, la hipoglucemia, la hipertrigliceridemia, latrombocitopenia y la anemia. Las complicaciones deben ser descartadas y tratadas en el diagnóstico y durante el seguimiento. La complicación másimportante es la hipercalcemia.

A widespread form of eruptive collagenomas in a 12-year-old man is presented for the impressive iconography, challenging differential diagnosis, and histopathological considerations associated with such rare connective tissue disorders. Syndromic forms should be carefully investigated for the different course and prognosis. Treatment is a major unsolved issue as aesthetic concerns are significant, especially in young adults.

Brachial plexus neuropathy is often seen in the military population, especially due to pressure (backpack palsy, BPP) or idiopathic (neuralgic amyotrophy, NA). We aimed to gain insight in the disease characteristics of soldiers with brachial plexus neuropathies in the Dutch military population and to compare disease characteristics between patients with BPP and NA. In this retrospective chart review study we aimed to include all patients with brachial plexus neuropathy, who presented in the Joint Military Hospital between 1 January, 2011 and 31 December, 2016. We calculated the incidence of NA and BPP and Chi-square tests or Student t tests were performed for differences in patient characteristics between NA and BPP. We included 127 patients, 63 with BPP, 45 with NA, 10 with traumatic brachial plexus neuropathy, and 9 with other plexopathy. The incidence of brachial plexus neuropathy was 50/100 000 person years overall, 25/100 000 person years for BPP, and 18/100 000 person years for NA. Patients in the BPP group differed from the NA with regard to pain (BPP 41% vs NA 93%, P = .000), atrophy (13% BPP vs 29% NA, P = .049), and sensory symptoms (83% BPP vs 44% NA, P = .000). In the BPP group 90% had incomplete recovery and in the NA group 78%. Our study showed a high incidence of BPP and NA in the military population and suggests recovery is not so benevolent as previously thought. Future research is necessary to improve insight and outcome of military patients with brachial plexus neuropathies., (© 2020 The Authors.

A 65-year-old man was found lifeless in his apartment, laying in a peculiar head-down position. His head was on the floor and his neck was over-flexed, with his trunk flexed on his neck. Examination of the body showed intense violet lividity of the head, torso and limbs, according to the position of the body. Moreover, diffuse hemorrhagic spots on the shoulders, upper part of the back and upper arms, along with an intense arch-shaped purple area on the anterior neck were detected at external examination. Suspicions of neck injuries due to strangulation and death due to positional asphyxia arose, but a thorough examination of circumstantial data and autopsy findings enabled a correct identification of cause and manner of death, and excluded strangulation and positional asphyxia as the cause of death. This case raises several issues on differential diagnosis and underlines the importance of a correct combined analysis of the findings provided by on-scene investigation and autopsy.

Complicated epidermoid cysts (ECs) occur commonly on the back, but few reports have described their management. We present our experience in managing patients with ECs on the back using a keystone-design perforator island flap (KDPIF) reconstruction, thereby focusing on reduction and redistribution of wound tension. Altogether, 15 patients (average age, 48.067 ± 14.868 years) underwent KDPIF reconstructions after complete excision of complicated ECs on the back. We retrospectively reviewed the medical records and clinical photographs of all patients. Final scar appearance was evaluated using the Patient and Observer Scar Assessment Scale (POSAS). All patients had ruptured ECs, while 6 patients also had cellulitis of the surrounding tissues. All defects, after complete excision of ECs and debridement of surrounding unhealthy tissues, were successfully covered with KDPIF. The mean 'tension-change' at the defect and donor sites was -4.73 ± 0.21 N and -4.88 ± 0.25 N, respectively (p < 0.001). The mean 'rate of tension-change' at the defect and donor sites was -69.48 ± 1.7% and -71.16 ± 1.33%, respectively (p < 0.001). All flaps survived with no postoperative complications. The mean observer scar assessment scale (OSAS) summary score and patient scar assessment scale (PSAS) total score were 14.467 ± 5.069 and 15.6 ± 6.512, respectively. Overall, we suggest that KDPIF reconstruction is a good surgical modality for the management of complicated ECs on the back.

Background: Quantifying the number of people with and types of disabilities is helpful for medical, policy, and public health planning., Objective/hypothesis: To update prior estimates on types, prevalence, and main causes of disability among U.S. adults using the Survey of Income and Program Participation (SIPP) data., Methods: We used cross-sectional data from the SIPP 2008 Panel Wave 6 interviews collected May-August 2010. Analyses were restricted to non-institutionalized adults ages ≥18 years (n = 66,410). Disability was ascertained via five non-mutually exclusive components: 1) specific activity difficulties, 2) selected impairments, 3) use of an assistive aid, 4) household work limitations, and 5) paid work limitations. Prioritized main cause of disability was established for the 95% of respondents with a disability type eligible for health condition questions. We generated weighted population estimates (number and percentage, with 95% confidence intervals (CIs)), accounting for the complex sample survey design., Results: 50 million U.S. adults (21.8%) experienced a disability in 2010. Mobility-related activity limitations were the most prevalent disabilities across all five components. The most common main causes of disability were arthritis/rheumatism, 9.1 million (19.2%, 95% CI = 18.4-20.0) and back or spine problems, 8.9 million (18.6%, 95% CI = 17.9-19.3)., Conclusions: A growing population with disabilities has the potential to put considerable and unsustainable demand on medical, public health, and senior service systems. Strengthening clinical community linkages and expanding the availability of existing evidence-based public health interventions to prevent, delay, and mitigate the effects of disability could improve health and outcomes for people with disabilities., (Published by Elsevier Inc.)

Background/aim: Verrucous epidermal nevi are cutaneous hamartomas with many clinical variants. Dermoscopic features of verrucous epidermal nevus have rarely been investigated. We aimed to identify dermoscopic findings of the entity which will facilitate the diagnostic process by reducing the use of invasive diagnostic methods., Materials and Methods: The study included the patients with histopathologically approved verrucous epidermal nevus. Clinical, dermoscopic, and histopathological features of the patients were retrospectively reviewed and the findings identified were recorded. Dermoscopic examination was performed with a polarized-light handheld dermoscope with 10-fold magnification., Results: The most common dermoscopic features were thick brown circles, thick brown branched lines, and terminal hairs. The most common vessel pattern was dotted vessels. Branched thick brown lines, brown globules, brown dots forming lines, serpiginous brown dots, white and brown exophytic papillary structures, fine scale, thick adherent scale, and cerebriform structures were the other findings., Conclusion: We observed many vascular and nonvascular dermoscopic findings which were not described previously for the entity. Dermoscopic examination of the verrucous epidermal nevi may lead to more reliable clinical interpretation and thus may reduce the need for histopathological investigation., (This work is licensed under a Creative Commons Attribution 4.0 International License)

Background/objectives: Since a high prevalence of back anomalies has been reported among subjects with crossbite, the aim was to assess the degree of back symmetry among subjects with (crossbite) and without (control) unilateral functional crossbite during the pre-pubertal growth phase., Methods: A group of 70 subjects (36 boys, 34 girls; 6.8 ± 1.2 years) in the primary or mixed dentition phase were included. Clinical assessment of head posture, shoulder, scapula and hip height were performed with the subject standing, and differences between the left and right side greater than 5 mm recorded. Asymmetry of the scapula and trunk prominence greater than 8 mm was recorded along with the prominence of thoracic and lumbar paravertebral musculature during the forward-bending test. Back symmetry was assessed qualitatively and quantitatively on colour deviation maps of superimposed mirrored three-dimensional back scans at a tolerance level of 2 mm., Results: No significant differences were observed between the groups regarding the frequency of clinically assessed back anomalies. The percentage of back symmetry was slightly lower in the crossbite than that in the control group (71.4 ± 13.3% and 79.2 ± 12.1%, respectively). A significant association (P < 0.05) was seen between scapula plane inclination (OR = 3.41) and scapula prominence inequalities (OR = 3.29) and unilateral functional crossbite, while hip height inequalities (OR = 0.94) were more frequent in the control group. No associations were detected between the side of crossbite and side of prominence of back parameters., Limitations: The use of different thresholds for clinical (5-8 mm) and three-dimensional (2 mm) symmetry assessment., Conclusions: Although some degree of back asymmetry was detected in the crossbite group during the pre-pubertal growth phase, this asymmetry does not appear to be clinically relevant., (© The Author(s) 2018.

Syringotropic mycosis fungoides (STMF) is an extremely rare form of cutaneous T‑cell lymphoma with 51 published cases so far. Clinically STMF is manifested similarly to folliculotropic mycosis fungoides (MF), whereby the course of STMF is much milder. Histopathologically, it shows a prominent tropism of the T‑cell lymphocytic infiltrate for the eccrine epithelium. We report the case of a 65-year-old woman with multiple small papules on the feet, shinbones and back.

Lichen planus pigmentosus (LPP) is an uncommon variant of lichen planus of unclear etiology that predominantly affects patients of skin types III to VI. We report a case of LPP of two years duration in a 67-year-old man involving upper extremities, chest, abdomen, and upper back.

Background and Design: Chronic nonspecific low back pain (CNSLBP) has major socioeconomic as well as personal impact in many industrialized and developing countries. Physiotherapy is a common intervention for this group of patients and using anti-pain physical modalities is a common part of the physical therapy. In a randomized controlled trial we investigated the immediate effect of the Diadynamic current in comparison to TENS on reducing the pain in patients suffering from non specific chronic low back pain., Methods: Thirty patients were randomized into the Diadynamic current and TENS groups. Electrical stimulation was applied for 10 min in the Diadynamic group and for 15 min in the TENS group for one session. Pain, on a 100 mm Visual Analog Scale, and Pressure Pain Threshold (PPT), using an Algometer, was measured before the treatment, after the current application, 20 min later and after 48 h., Results: Pain was decreased significantly after 20 min following the current application only in the TENS group, with no improvement at all measurement points in the group receiving Diadynamic current. PPT was increased immediately after current application in both groups but did not last until later measurements., Conclusion: Diadynamic current had no positive effect on prompt relief of pain in patients suffering from recurrent CNSLBP., (Copyright © 2017 Elsevier Ltd.

Introduction: Porokeratosis is a benign hyperkeratotic skin tumour due to a clonal proliferation of keratinocytes and is characterised by a telltale annular threadlike configuration along the border of a skin-colored to erythematous papule that can expand centrifugally., Case Presentation: We are presenting a clinical and dermoscopic case of pigmented disseminated superficial actinic porokeratosis (DSAP) limited to the upper trunk of a white man with sun-damaged skin. Literature Review and Conclusion: A thorough review of PubMed failed to identify any previous reports on the dermoscopic appearance of pigmented porokeratosis. On dermoscopy, the presence of black dots limited to the periphery of the lesions is due to pigment incontinence and melanophages within the superficial papillary dermis limited to the area below the cornoid lamella. Pigmented DSAP is a unique morphological presentation of porokeratosis, and it is essential to be familiar with its clinical and dermoscopic presentation.

Objectives: Characteristics of muscle activity, represented by surface electromyography (EMG), have revealed differences between patients with low back pain (LBP) and healthy adults; how they relate to functional and clinical parameters remains unclear. The purpose of the current study was to examine the correlation between frequency characteristics of EMG (analysed using continuous wavelet transform (CWT) analysis) and patients' self-rated score of disability., Design and Setting: This is a case-control study with 15 patients with mechanical LBP without radicular symptoms. Patients were recruited from the orthopaedic clinic at Charing Cross Hospital. Ten healthy adults were recruited from the staff working in the hospital and associated university. Patients completed the Roland-Morris Disability Questionnaire (RMDQ) and bilateral EMG activity was obtained from erector spinae at vertebral levels L4 and T12. Subjects performed three brief maximal voluntary isometric contractions (MVICs) of the back extensors and the torque was measured using a dynamometer. CWT was applied to the EMG signals of each muscle in a 200 ms window centred around the peak torque obtained during the MVICs. The ratio (low/high frequencies) of the energy, the peak power and the frequency of the peak power were calculated for each recording site, averaged and correlated with the individual's RMDQ score., Results: Patients had lower peak power (T12 and L4) and lower frequency of the peak power (at T12) than the healthy adults. Additionally, RMDQ positively correlated to the average ratio of energy at T12 (r=0.63; p=0.012), that is, greater self-rated disability corresponded to a dominant distribution of energy in the lower frequencies., Conclusion: The current findings reveal alterations in EMG profile and its association with self-related back pain disability, suggesting that spectral characteristics of EMG reflect muscle function., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

We describe the largest reported case of pilomatrixoma in the literature. While pilomatrixomas typically present as small soft-tissue nodules of the head, neck and upper extremities, they can also present as much larger masses in atypical locations. When they present in their usual size, pilomatrixomas have typical imaging features and can be correctly diagnosed with imaging studies before histological confirmation. Their clinical and imaging diagnosis become challenging when they are very large, as in our case. A giant pilomatrixoma should also be considered for paediatric patients presenting with a large subcutaneous soft-tissue mass.

Background: This study examines the clinical characteristics and demographics of teenage boys with horizontal striae distensae of the lower back in an outpatient setting., Methods: Retrospective medical chart reviews and telephone survey studies were completed on an outpatient cohort of 12 boys 11 to 17 years of age with a clinical diagnosis of transverse striae distensae of the lower back at a single-center, university-based, pediatric dermatology practice. We evaluated the clinical features of the striae, participant demographic characteristics, and past medical history. A review of the literature concerning risk factors was conducted using PubMed and Google Scholar., Results: Of the 14 patients we contacted, 12 agreed to participate. The average age of onset for the striae was 14.3 years. All boys were above the 50th percentile in height at the time of onset. Eight (66.7%) reported a significant growth spurt before the appearance of the stretch marks. Most were asymptomatic. None of the boys had a history of unmonitored exogenous steroid use or prior infection with Bartonella henselae or Borrelia burgdorferi. Only one (8.3%) had a chronic medical condition. Eleven (91.7%) had at least one first-degree relative with striae distensae., Conclusion: Our results indicate that horizontal striae distensae of the lower back in adolescent boys is associated with a rapid growth spurt, tall stature, and family history of striae distensae. There is no association between this type of striae distensae and any chronic medical condition, bacterial infection, or exogenous steroid use. Thus a careful review of systems and counseling without further medical testing is reasonable management., (© 2017 Wiley Periodicals, Inc.)

Background: A wide variety of drugs can cause cutaneous vasculitis. Herein we report a case of immune complex vasculitis induced by amiodarone., Patients and Methods: A 57-year-old patient reported a recent history of pruritus associated with large erythematous, inflammatory, necrotic plaques localized on the lower limbs and back. These cutaneous lesions had appeared less than 2 months after initiation of amiodarone for supra-ventricular arrhythmia. Histological and direct immunofluorescence examinations of a skin biopsy sample revealed vasculitis with the presence of IgM and C3 immune complexes in vessels. The remaining laboratory tests were unremarkable (in particular, cryoglobulin and autoantibody tests were negative). The patient himself attributed his symptoms to the recent administration of amiodarone and spontaneously stopped the drug without medical advice. No other therapy was prescribed. Following drug withdrawal, the lesions that had been present for more than 4 months completely disappeared. No recurrence occurred after follow-up of over 6 months. The diagnosis of amiodarone-induced vasculitis was retained., Discussion: Fewer than 10 cases of amiodarone-induced vasculitis have been reported in the medical literature. It is not known whether this entity is rare, under-diagnosed or under-reported., (Copyright © 2017 Elsevier Masson SAS. All rights reserved.)

Objective: The aims of the study were to evaluate the medium-term effects of diadynamic (DD) currents on relieving symptoms/improving physical functionality in patients with chronic low back pain (LBP) and to compare the efficacy of DD versus TENS., Methods: The patients were divided into two groups as the TENS group (n = 26) and the DD group (n = 29). Additional treatment of hot pack + therapeutic ultrasound was applied to all patients. The therapy programs were administered as a total of 10 sessions over a period of 2 weeks. Roland Morris Disability Questionnaire (RDQ), Oswestry Disability Index and Visual Analog Scale (VAS) values were recorded., Results: Both groups showed significant improvements in VAS and RDQ scores after one month of the therapies (all p < 0.05)., Conclusion: Using TENS and DD currents in chronic LBP can lead to reduced pain, and improved physical functions. Hence, DD currents can be used as an adjuvant therapy for rehabilitation of chronic LBP., (Copyright © 2017 Elsevier Ltd. All rights reserved.)
