During dysphagia treatment, direct oral swallowing therapy is applied to some patients temporarily fed via nasogastric tube. However, the risk of aspiration in oral swallowing while nasogastric tube in situ may be disregarded in a standard videofluoroscopic swallowing study performed without a nasogastric tube. To evaluate the diagnostic significance of nasogastric tube in situ videofluoroscopic swallowing study of nectar and pureed diet compared to the standard videofluoroscopic swallowing study without nasogastric tube. Videofluoroscopic swallowing study records of dysphagia patients conducted between June and August 2017 in a university hospital were collected for review. Rosenbek’s penetration-aspiration scale, diagnostic criteria of aspiration were used to define aspiration. videofluoroscopic dysphagia scale for videofluoroscopic swallowing study with or without nasogastric tube were compared for nectar and pureed diet swallowing. Patients had various duration of nasogastric tube feeding. Paired T-test comparing the videofluoroscopic dysphagia scales for videofluoroscopic swallowing study with or without nasogastric tube revealed significant aggravation of swallowing dysfunction in nectar drinking while nasogastric tube in situ. This aggravation was noted in 19% (n=4) of patients who suffered from stroke regardless of nasogastric tube duration. Nasogastric tube in situ videofluoroscopic swallowing study, at least of nectar drinking could be beneficial in selecting a safe candidate for direct oral swallowing therapy in conjunction with the conventional nasogastric tube removed videofluoroscopic swallowing study.

Lower extremity lymphedema (LEL) is a well-known adverse effect related to cervical and endometrial cancer (CEC); however, very few studies have elucidated the clinicopathologic risk factors related to LEL. We investigated the incidence and risk factors in patients who received primary surgery and/or adjuvant radiotherapy (RT) or chemotherapy for CEC.We retrospectively reviewed 2,565 patients who underwent primary surgery following CEC diagnosis between January 2007 and December 2020. LEL diagnosis was based on objective and subjective assessments by experts. We identified important predictors of LEL to construct a nomogram predicting individual risks of LEL. For internal validation of the nomogram, the original data were separated using the split-sample method in a 7:3 ratio of training data and test data.Overall, 858 patients (33.5%) received RT, 586 received external beam RT (EBRT), and 630 received intracavitary RT. During follow-up period, LEL developed in 331 patients, with an overall cumulative 5-year incidence of 13.3%. In multivariate analysis, age at primary treatment, use of docetaxel-based chemotherapy, type of hysterectomy, type of surgical pelvic lymph node (LN) assessment, number of dissected pelvic and para-aortic LNs, and EBRT field were the independent predictors of LEL. We subsequently developed the nomogram showing excellent predictive power for LEL.LEL is associated with various treatment modalities, and their interactions may increase the possibility of occurrences. De-escalation strategies for treatment modalities should be considered to reduce LEL in patients with CEC.

Cervical and upper thoracic spinal cord injury causes impairments in respiratory muscle performance, leading to variable degrees of pulmonary dysfunction and rendering deep breathing difficult for affected individuals. In this retrospective study, we investigated the effects of self-directed respiratory muscle training in this context by assessing pulmonary function relative to spinal cord injury characteristics. A total of 104 spinal cord injury patients (tetraplegia/paraplegia; 65/39, acute/subacute/chronic; 14/42/48) were admitted for short-term (4–8 weeks) in-patient clinical rehabilitation. Initial evaluation revealed a compromised pulmonary function with a percentage of predicted value of 62.0 and 57.5 in forced vital capacity in supine and forced vital capacity in sitting positions, respectively. Tetraplegic patients had more compromised pulmonary function compared with paraplegic patients. At follow-up evaluation, the percentage of predicted value of forced vital capacity in supine and sitting position improved overall on average by 11.7% and 12.7%, respectively. The peak cough flow improved by 22.7%. All assessed pulmonary function parameters improved significantly in all subgroups, with the greatest improvements found in patients with tetraplegia and subacute spinal cord injury. Therefore, short-term self-directed respiratory muscle training should be incorporated into all spinal cord injury rehabilitation regimens, especially for patients with tetraplegia and subacute spinal cord injury, as well as those with chronic spinal cord injury.

Repetitive magnetic stimulation (rMS) has been suggested as a non-invasive treatment for various neurological or psychiatric diseases. Contrary to the application previously used, the purpose of the present study was to elucidate whether low-frequency rMS could suppress tumor progression in in vitro and in vivo neuroblastoma models, and to explore the underlying mechanisms. The results demonstrated that low-frequency rMS treatment significantly suppressed cell proliferation and tumor progression in the models. Moreover, low-frequency rMS treatment downregulated the Wnt/β-catenin signaling pathway and induced apoptosis. The Wnt/β-catenin signaling pathway activator, Wnt agonist, was found to counteract the effect of low-frequency rMS treatment, while the Wnt/β-catenin signaling pathway inhibitor, Wnt antagonist, exhibited a tumor suppression effect, similar to the effect of low-frequency rMS treatment. Taken together, our data demonstrated that low-frequency rMS treatment suppressed neuroblastoma progression by downregulating the Wnt/β-catenin signaling pathway, suggesting that low-frequency rMS treatment may be a potential therapeutic strategy for the tumor suppression.

Background The geriatric population and advanced knee osteoarthritis are rapidly increasing in Korea, and the socioeconomic burden of total knee arthroplasty (TKA) is increasing. This study aimed to analyze the demographic, clinical and socioeconomic characteristics of patients who underwent TKA and to differentiate the factors affecting participation in inpatient-intensive rehabilitation programs after TKA in the Jeju regional rheumatoid and degenerative arthritis center established by the government. Methods This retrospective cohort study included 845 patients (735 females; 72.0 ± 5.8 years) diagnosed with primary osteoarthritis (OA) of the knee who underwent elective unilateral primary TKA between January 2013 and June 2016. Demographic, clinical, and socioeconomic characteristics, including age, body mass index, obesity, length of stay, OA severity, underlying disease, education level, occupation, and location of residence were reviewed. Patients were allocated to the TKA-only group (home discharge) and to the TKA + rehab group (participation in post-TKA rehabilitation). The variables were analyzed and compared before and after the establishment of the center and according to participation in intensive rehabilitation. Results Patients who underwent TKA were mostly female, in the 60 s, and had a high prevalence of comorbidities and obesity. After the rehabilitation center's establishment, the intensive post-TKA participation increased profoundly from 3% to 59.2%. Participants after the center establishment had lower mean BMI and a higher proportion of K-L grade 4 compared to those before the center establishment. The location of residence was the only factor differentiating the participation in the intensive rehabilitation. Conclusion The regional rheumatoid and degenerative arthritis center was appropriate to satisfy the high unmet need for participating in the intensive rehabilitation after TKA and to execute the qualified integrated post-TKA care system. Policy support should ensure the early rehabilitation and a qualified integrated care system and prepare for the increased burden of revision. Future longitudinal studies should be conducted to assess the long-term effect of the integrated post-TKA rehabilitation program on functional outcomes and patient survivorship free from revision.

Cachexia and low muscle mass in motor-complete tetraplegia are associated with poor outcomes. This study aimed to document anthropometric, body composition, and nutritional indices in patients and to assess the effect of a comprehensive rehabilitation nutrition program in cachexia and low muscle mass. For 34 motor-complete tetraplegia in the subacute phase, a comprehensive rehabilitation nutrition program was provided for 8 to 9 weeks. Risk of malnutrition, anthropometric and body composition indices, as well as laboratory tests were assessed upon admission and at discharge. A body mass index of less than 20.2 kg/m2 was used as the cut-off value for obesity. Upon admission, 73.5% of patients were classified as obese, half were at risk of malnutrition, and 29.4% were compatible with cachexia. Compared to the premorbid state, the non-obese group showed greater weight reduction (p < 0.01) and higher prevalence of low muscle mass (p = 0.004) than the obese group. Disease duration was different between groups (p < 0.01). After rehabilitation, malnutrition risk, protein levels, and hemodynamic results improved in both groups (p < 0.05). A significant time × group interaction was observed for muscle mass, skeletal muscle mass, and appendicular lean mass index (p < 0.05). Muscle mass was maintained while fat components increased in both groups. Functional improvement was negatively correlated with an increase in fat components (p < 0.05). A personalized rehabilitation nutrition intervention improved the nutritional status, body composition, and functional outcomes in motor-complete tetraplegia. The increase in muscle mass was associated with functional gain; healthy weight gain or maintenance may improve the level of independence. Further studies to endorse this beneficial evidence of rehabilitation nutrition in the maintenance of muscle component are needed.

Osteoarthritis is a common degenerative disease that most frequently involves the hand. The objective was to compare clinical functional outcome measures including hand grip, pinch strength, and dexterity with various electrophysiological measures in patients of different ages with hand osteoarthritis with or without the presence of carpal tunnel syndrome (CTS). Patients with hand osteoarthritis (208 patients, 404 hands) who underwent hand-function tests and motor and sensory nerve conduction studies (NCS) between June 2015 and June 2016 were enrolled. The patients’ hands were assigned to carpal tunnel syndrome (CTS) (206 hands; mean age, 56.37 ± 10.52; male:female, 46:160) or control groups (198 hands; mean age, 57.88 ± 9.68; male:female, 55:143). The strength of hand grip and lateral pinch, the time required to complete the nine-hole pegboard test (9HPT), and motor and sensory nerve conduction parameters were measured and compared across age groups and between hands with or without CTS. The CTS group showed significantly lower hand grip and lateral pinch strength, and a longer time to complete the 9HPT in comparison with the control group. Female patients showed significantly lower hand grip and lateral pinch strength than male patients. However, there was no difference in the 9HPT completion time between genders. Multivariate regression analysis identified the amplitude of the median compound muscle action potential (CMAP), age, and male gender as independent predictors of grip strength (adjusted R2 = 0.679), and amplitude of median CMAP and male gender as independent predictors of KP strength (adjusted R2 = 0.603). Velocity of median CMAP, amplitude of median sensory nerve action potential, and age were identified as independent predictors of 9HPT time (adjusted R2 = 0.329). Nerve conduction measurements were significantly related to hand-function test results, and CTS induced significant deficits in strength and performance of the affected hand.

Background: Cancer treatment-related lymphedema (CTRL) affects patients physically, psychologically and emotionally, and remains a significant quality of life issue among patients with cancer. Reliable methods to measure changes in lymphedema are required for early detection, acute intensive treatment, and long-term management. Here, we evaluated the use of bioimpedance analysis (BIA) as a tool to measure lymphedema before and after treatment.Patients and Methods: Patients with CTRL who were admitted to a secondary university hospital between October 2017 and July 2018 for complex decongestive therapy (CDT) were eligible for this prospective cohort study. Circumferential measure (CM) and BIA were used to evaluate lymphedema at admission (initial) and before discharge (follow-up, FU). Volume was calculated from the CM using the truncated cone formula. The inter-limb ratios (ILRs) of the circumference, volume, and impedance were also calculated as the unaffected limb to affected limb. Each parameter before and after treatment and correlations between parameters also were analyzed.Results: A total of 29 patients (12 upper- and 17 lower-extremity CTRL) completed were included in this analysis. Absolute value and the ILRs of circumference, volume or impedance, and extracellular water/total body water (ECW/TBW) were significantly improved at FU (p < 0.01, p < 0.05). The initial and FU absolute values, ILRs, ECW/TBW correlated significantly with each other (p < 0.01, p < 0.05). The cutoff values of ECW/TBW for moderate and severe degree of CTRL were 0.3855 and 0.3955, respectively. The changes of ILRs between initial and FU assessments were significantly different among three groups according to lymphedema severity (p < 0.01, p < 0.05).Conclusions: BIA data correlates significantly with clinical measurement, and therefore can be a practical tool in monitoring outcome measure after lymphedema treatment. In addition, BIA is more sensitive to subtle changes in lymphedema, and therefore can be useful for the long-term maintenance of lymphedema.

International audience; OBJECTIVE: The aim of this study was to identify the comprehensive risk factors for lymphedema, thereby enabling a more informed multidisciplinary treatment decision-making. SUMMARY BACKGROUND DATA: Lymphedema is a serious long-term complication in breast cancer patients post-surgery; however, the influence of multimodal therapy on its occurrence remains unclear. METHODS: We retrospectively collected treatment-related data from 5549 breast cancer patients who underwent surgery between 2007 and 2015 at our institution. Individual radiotherapy plans were reviewed for regional nodal irradiation (RNI) field design and fractionation type. We identified lymphedema risk factors and used them to construct nomograms to predict individual risk of lymphedema. Nomograms were validated internally using 100 bootstrap samples and externally using 2 separate datasets of 1877 Asian and 191 Western patients. RESULTS: Six hundred thirty-nine patients developed lymphedema during a median follow-up of 60 months. The 3-year lymphedema incidence was 10.5%; this rate increased with larger irradiation volumes (no RNI vs RNI excluding axilla I-II vs RNI including axilla I-II: 5.7% vs 16.8% vs 24.1%) and when using conventional fractionation instead of hypofractionation (13.5% vs 6.8%). On multivariate analysis, higher body mass index, larger number of dissected nodes, taxane-based regimen, total mastectomy, larger irradiation field, and conventional fractionation were strongly associated with lymphedema (all P < 0.001). Nomograms constructed based on these variables showed good calibration and discrimination internally (concordance index: 0.774) and externally (0.832 for Asian and 0.820 for Western patients). CONCLUSIONS: Trimodality breast cancer treatment factors interact to promote lymphedema. Lymphedema risk can be decreased by deintensifying node dissection, chemotherapy regimen, and field and dose of radiotherapy. Deescalation strategies on a multidisciplinary basis might minimize lymphedema risk. Copyright

Objective To present a new stimulation method based on the use of a head-mounted display (HMD) during pattern reversal visual evoked potential (PR-VEP) testing and to compare variables of HMD to those of conventional cathode ray tube (CRT). Methods Twenty-three normal subjects without visual problems were recruited. PR-VEPs were generated using CRT or HMD stimuli. VEP outcome measures included latencies (N75, P100, and N145) and peak-to-peak amplitudes (N75-P100 and P100-N145). Subjective discomfort associated with HMD was determined using a self- administered questionnaire. Results PR-VEPs generated by HMD stimuli showed typical triphasic waveforms, the components of which were found to be correlated with those obtained using conventional CRT stimuli. Self-administered discomfort questionnaires revealed that HMD was more comfortable in some aspects. It allowed subjects to concentrate better than CRT. Conclusion The described HMD stimulation can be used as an alternative to the standard CRT stimulation for PR- VEPs. PR-VEP testing using HMD has potential applications in clinical practice and visual system research because HMD can be used on a wider range of subjects compared to CRT.

Objectives : To assess the changes of ultrasonographic findings of median nerve according to the change of wrist positionsin normal adults.Methods : We studied 26 normal hands using musculoskeletal ultrasonography. A cross-sectional area, antero-posteriordiameter, transverse diameter and a flattening ratio of median nerve were measured in neutral, in 30 degree of flexion and in30 degree of extension positions of the wrist.Results : The cross-sectional area of median nerve was significantly increased on the wrist flexion (P

OBJECTIVE The aim of this study was to assess whether the effects of a motorized aquatic treadmill exercise program improve the isometric strength of the knee muscles, cardiorespiratory fitness, arterial stiffness, motor function, balance, functional outcomes, and quality of life in subacute stroke patients. DESIGN Thirty-two patients were randomly assigned to 4-wk training sessions of either aquatic therapy (n = 19) or land-based aerobic exercise (n = 18). Isometric strength was measured using an isokinetic dynamometer. Cardiopulmonary fitness was evaluated using a symptom-limited exercise tolerance test and by measuring brachial ankle pulse wave velocity. Moreover, motor function (Fugl-Meyer Assessment [FMA] and FMA-lower limb [FMA-LL]), balance (Berg Balance Scale [BBS]), Activities of daily living (Korean version of the Modified Barthel Index [K-MBI]), and quality of life (EQ-5D index) were examined. RESULTS There were no intergroup differences between demographic and clinical characteristics at baseline (P > 0.05). The results shows significant improvements in peak oxygen consumption (P = 0.02), maximal isometric strength of the bilateral knee extensors (P < 0.01) and paretic knee flexors (P = 0.01), FMA (P = 0.03), FMA-LL (P = 0.01), BBS (P = 0.01), K-MBI (P < 0.01), and EQ-5D index (P = 0.04) after treatment in the aquatic therapy group. However, only significant improvements in maximal isometric strength in the knee extensors (P = 0.03) and flexors (P = 0.04) were found within the aquatic therapy group and control group. CONCLUSIONS Water-based aerobic exercise performed on a motorized aquatic treadmill had beneficial effect on isometric muscle strength in the lower limb.

Background: The aim of this study is to test if adjuvant hydrotherapy with viscosupplement is beneficial on management of pain, stiffness, function, and mental relaxation in knee osteoarthritis (OA). Methods: Nineteen patients with OA were randomly assigned to hydrotherapy or control groups. All patients received viscosupplement injections once a week for 3 weeks. Hydrotherapy group (n=9) had a spa containing green tea, 3 days a week for 2 weeks. The control group (n=10) received only injections. All patients were assessed at baseline and after the third injection. All were assessed for pain (visual analog scale, VAS), pain severity, and functional status (Western Ontario and McMaster Universities osteoarthritis index, WOMAC), emotional status, quality of life (Euro quality of life health-related quality of life inventory five dimension, EQ-5D), and relative spectral power of alpha waves in electroencephalography (EEG). Results: Both groups reported a statistically significant reduction of pain at the end of treatment and detailed assessment of pain, and function in WOMAC and the relative power of alpha in electroencephalogram showed statistical significant difference only in the hydrotherapy group. However, there were no significant intergroup differences, except for VAS score. Conclusion: Adjuvant 2-week hydrotherapy to viscosupplement might have a modest role in the management of pain and functional disability and the mental relaxation in patients with knee OA. Larger, randomized controlled trials with intervention of long term period to determine efficacy in treating knee OA are warranted.

Hemiballism describes involuntary severe, violent, arrhythmic, rotatory and large amplitude movements of limb from proximal joint. We experienced an elderly stroke patient with hemiballism accompanied dysphagia that persisted for several months severity was evaluated by the Universidade Federal de Minas Gerais Sydenham’s chorea rating scale (USCRS) and video fluoroscopic swallowing study (VFSS). In this case, we observed the improvement of hemiballism by conventional rehabilitation therapy and low dose quetiapine. Therefore, we recommend geriatrists considers vthese therapies in elderly patients with hemiballism.

To assess the feasibility and safety of a 6-week course of water walking performed using a motorized aquatic treadmill in individuals with subacute stroke for cardiorespiratory fitness, walking endurance, and activities of daily living.Twenty subacute stroke patents were randomly assigned to aquatic treadmill exercise (ATE) or land-based exercise (LBE). The ATE group (n = 10) performed water-based aerobic exercise on a motorized aquatic treadmill, and the LBE group (n = 10) performed land-based aerobic exercise on a cycle ergometer. Both groups performed aerobic exercise for 30 minutes, 5 times per week for 6 weeks. Primary outcome measures were 6-minute walk test for walking endurance and cardiopulmonary fitness parameters of a symptom-limited exercise tolerance test, and secondary measures were Korean version of the Modified Barthel Index (K-MBI) for activities of daily living. All variables were assessed at baseline and at the end of the intervention.The ATE group showed significant improvements in 6-minute walk test (P = .005), peak oxygen uptake ((Equation is included in full-text article.)O2peak; P = .005), peak heart rate (P = .007), exercise tolerance test duration (P = .005), and K-MBI (P = .008). The LBE group showed a significant improvement only in K-MBI (P = .012). In addition, improvement in (Equation is included in full-text article.)O2peak was greater in the ATE than in the LBE group.This preliminary study showed that a 6-week ATE program improved peak aerobic capacity and walking endurance in patients with subacute stroke. The improvement in (Equation is included in full-text article.)O2peak after an ATE exercise program was greater than that observed after an LBE program. Therefore, ATE effectively improves cardiopulmonary fitness in patients with subacute stroke.

Background: The present study aims to explore the effect of weight bearing exercise on bone mineral density (BMD) and bone growth in children with cerebral palsy (CP). Methods: Twelve children with CP of functional level of gross motor functional classification scale (GMFCS) V and 6 healthy children (control group) were included in the study. Participants underwent a dual-energy X-ray absorptiometry scan to measure the BMD of the femur and full-length anteroposterior radiography to measure the bone length of the femur and tibia at baseline and after 6 months. Patients were randomly divided into 2 groups: group A with programmed standing exercises and assisted standing for more than 2 hours a day, more than 5 days a week; and group B with conventional physiotherapy with a standing program for 20 minutes a day, 2 to 3 days a week. Results: A 6-month follow-up showed significantly increased BMD on the femur neck in the control group. Although the changes in BMD were not significant in both groups, group A demonstrated an increased trend of BMD, whereas group B showed a decreased trend. Bone length was significantly increased in all 3 groups at the 6-month follow-up. Although this increase was not significant, the change in bone length was greatest in the control group. The smallest changes were observed in group B. Conclusions: Weight bearing exercise may play an important role in increasing or maintaining BMD in children with CP and is also expected to promote bone growth. Programmed standing may be used as an effective treatment method to increase BMD in children with CP. However, further studies with a larger cohort and longer follow-up period are required to reveal further information on the benefit of weight bearing exercise and to develop a detailed program.

Department of Psychiatry, Myongji Hospital, Kwandong University College of Medicine, Goyang, KoreaEarly detection and intervention is critical in improving prognosis of developmental disorders. Developmental delay can have many different causes and the clinical features of developmental delay are diverse according to its etiologic causes and severity. The vast and rapid growth of the child’s neurobehavioral repertoire from birth through adolescence requires the physician’s abun-dant experience, knowledge, and understanding of development. Here, we summarize instruments for use in neurodevelopmental assessment of infants and toddlers, focusing on motor development, which is the most frequent complaint listed in the develop-mental clinic.

This article review on physiology, prescription , and program of cardiac rehabilitation and- promotes its safety and importance to clinicians. The network of cardiac rehabilitation, based on regional cardiocerebrovascular center and interdisciplinary team approach should be emphasized.

Objective The purpose of this study was to investigate the feasibility of using real-time high-resolution sonography to guide an injection needle into the intra-articular space within the knee. Methods Eighty-nine patients with radiographically confirmed knee osteoarthritis (Kellgren-Lawrence grade 2 or 3) without an effusion were included. After sonographically guided or blind injection of hyaluronic acid (HA) and contrast dye through a medial patellar portal (MPP) into the knee joint, a radiographic image was made to ascertain whether the injected material had reached the intra-articular space. Result Sonographically guided injections of HA into the knee joint had a significantly greater accuracy rate (95.6%) than blind injections (77.3%; P = .01). Conclusions Intra-articular injections via an MPP using sonographic guidance may raise the accuracy rate in knee joint injections.

Chang WH, Im SH, Ryu JA, Lee SC, Kim JS. The effects of scapulothoracic bursa injections in patients with scapular pain: a pilot study. Objective To assess the effects of steroid plus hyaluronate injections for scapulothoracic bursitis in patients with scapular pain. Design Prospective open-label unicenter trial with a 3-month follow-up. Setting University rehabilitation hospital. Participants Twenty-two cases of suspected scapulothoracic bursitis. Intervention Injections into scapulothoracic bursa were performed with steroid plus hyaluronate. Injections were administered once a week for 3 weeks. Main Outcome Measures Visual analog scale (VAS), Rubin scale, adverse events, and injection-associated complications. Results Mean outcome scores at 3-month follow-up visits showed significant improvements versus baseline (mean VAS increased from 7.8 to 2.2) ( P P Conclusions Scapulothoracic bursitis should be considered when treating patients with perimarginal scapular pain or subscapular pain. Our findings show that steroid plus hyaluronate injections into the scapulothoracic bursa provide an effective means of treating patients with scapulothoracic bursitis.

OBJECTIVE To investigate the energy expenditure (EE) of Korean young adults based on activities refined to a deskbound lifestyle. METHODS Sixty-four healthy office workers aged between 25 and 46 years participated in this study. EE was expressed as metabolic equivalent of task (MET). Participants were evaluated in terms of their EE during physical activities of sleeping (n=22), typing (n=37), folding laundry (n=34), dishwashing (n=32), studying (n=18), mopping (n=35), walking (n=33), stair climbing (n=23), and running (n=29). Volume of oxygen consumption was measured by indirect calorimetry K4b(2) (COSMED). The results were compared to the established Compendium MET. RESULTS The MET of activities were: sleeping, 1.24±0.43; typing, 1.35±0.25; folding laundry, 1.58±0.51; dishwashing, 2.20±0.51; studying, 2.11±0.90; mopping, 2.72±0.69; walking at 4 km/hr, 3.48±0.65; stair climbing of five stories, 6.18±1.08; and running at 8 km/hr, 7.57±0.57. The values of typing and mopping were similar to those in the Compendium, whereas those of sleeping, folding laundry, dishwashing, studying, walking, stair climbing and running were different. CONCLUSION To our knowledge, this estimation of EE in MET during activities of daily living is the first data of young adults in Korea. These data could be used as a reference to modify the guidelines of physical activities for the age group examined in this study.

Objective To compare quantitative muscle activation between erect and slouched sitting postures in the muscles around the scapula, and to investigate the correlation between the angle of thoracic kyphosis and the alteration of muscle activity depending on two different sitting postures. Methods Ten healthy males participated in the study. Unilateral surface electromyography (SEMG) was performed for serratus anterior, middle trapezius (MT), and lower trapezius (LT), which are scapular stabilizer muscles, as well as latissimus dorsi. Participants elevated their shoulders for 3 seconds up to 90° abduction in the scapular plane, tilting 30° anterior in the coronal plane. They were told to hold the position for 10 seconds and voluntary isometric contractions were recorded by SEMG. These movement procedures were conducted for three times each for erect and slouched sitting postures and data were averaged. Results Activities of MT and LT increased significantly more in the slouched sitting posture than in the erect one. There was no significant correlation between kyphotic angle and the area under curve of each muscle. Conclusion Because MT and LT are known as prime movers of scapular rotation, the findings of this study support the notion that slouched sitting posture affects scapular movement. Such scapular dyskinesis during arm elevation leads to scapular stabilizers becoming overactive, and is relevant to muscle fatigue. Thus, slouched sitting posture could be one of the risk factors involved in musculoskeletal pain around scapulae.

The latest National Survey on Persons with Disabilities estimated 2,683,400 persons with disabilities in South Korea, of whom 58% were men and 42% were women. People with physical disability represent approximately 50% of the entire population with disability. Disability-related policies and services to improve the participation of persons with disabilities have been expanded in the last decades, guided by 5-yr plans. The number of physiatrists has increased, although it still varies significantly by location. As part of the comprehensive measures to expand rehabilitation services, several regional rehabilitation centers have been established. In addition, a community-based rehabilitation program has been implemented that comprises Strong Point Public Health Centers, which provide local health promotion programs for persons with disabilities, family support programs, and community participation programs. As the aged population increases, it is predicted that the population of persons with disabilities in South Korea will also increase. A long-term and innovative financial model will be required to meet the corresponding needs. A recent milestone of evidence-based practice is the publication of Clinical Practice Guideline for Stroke Rehabilitation in Korea.

Objective To investigate the serum vitamin D level and its determinant factors in stroke patients. Methods Fifty-one stroke patients who had documented serum level of 25-hydroxyvitamin D(25(OH)D) were included. Patients were divided into subacute (n=23) and chronic groups (n=28). The mean levels of 25(OH)D of the two groups were compared. Correlations between each 25(OH)D level and post-stroke duration were also analyzed. To assess other possible influencing factors, patients were subdivided by ambulation ability and feeding methods for comparison of 25(OH)D level. Results The mean level of 25(OH)D was significantly lower in the chronic group than in the subacute group (12.3 vs. 16.3 ng/mL; p

Objective: Brachial–ankle pulse wave velocity (baPWV) evaluates arterial stiffness and also predicts early outcome in stroke patients. The objectives of this study were to investigate arterial stiffness of subacute nonfunctional ambulatory stroke patients and to compare the effects of robot-assisted gait therapy (RAGT) combined with rehabilitation therapy (RT) on arterial stiffness and functional recovery with those of RT alone.

Objective To correlate voluntary cough and laryngeal cough reflex (LCR) flows in patients with traumatic brain injury (TBI). Design Cross-sectional study. Setting University rehabilitation hospital. Participants Patients with TBI (n=25) and healthy controls (n=48). Interventions Not applicable. Main Outcome Measures Peak cough flows (PCFs) and LCR flows were measured using a peak flow meter at the oral-nasal interface. The largest value of 3 attempts was recorded for PCF and LCR, respectively. LCR was elicited by 20% solution of pharmaceutic-grade citric acid dissolved in sterile .15M NaCl solution that was inhaled from a nebulizer. Results PCF was 447.4±99.0L/min in the control group and 211.7±58.2L/min in the patient group. LCR was 209.2±63.8L/min in the control group and 170.0±59.7L/min in the patient group. Both PCF ( P =.000) and LCR ( P =.013) were significantly reduced in patients with TBI compared to that of the control group. LCR was strongly related to the PCF in both control ( R =.645; P =.000) and patient ( R =.711; P =.000) groups. Conclusions As LCR can be measured as a numerical value and significantly correlates with PCF, LCR can be used to estimate cough ability of patients with TBI who cannot cooperate with PCF measurement.

Rha D-W, Im SH, Kim S-K, Chang WH, Kim KJ, Lee SC. Median nerve conduction study through the carpal tunnel using segmental nerve length measured by ultrasonographic and conventional tape methods. Objective (1) To determine whether a 5-cm segment includes the entire anatomic carpal tunnel in live subjects, and to compare surface, ultrasonographic, and direct measures of the median nerve length in human cadavers. (2) To investigate the actual difference of sensory conduction velocities between the conventional tape method and the ultrasonographic method. Design Cross-sectional study. Setting University rehabilitation hospital. Participants Healthy volunteers (N=40; 20 men, 20 women). Interventions Not applicable. Main Outcome Measures Onset latencies at the palm and wrist, nerve conduction velocity (NCV) in nerve conduction study (NCS), median nerve length measured by ultrasound and tape method. Results A real-time ultrasonographic study revealed that a 5-cm segment included the entire carpal tunnel. In the cadaveric study, the median nerve length measured by ultrasound was closer to the actual nerve length than the conventional surface length. The median nerve length in the wrist-to-palm segment measured by ultrasound was shorter than the surface distance. The sensory NCV using the nerve length measured by ultrasound was slower than that using the surface distance ( P Conclusions The 5-cm segment test included the entire carpal tunnel and might be advantageous in the diagnosis of carpal tunnel syndrome (CTS), especially for early lesions. We expect that ultrasonographic measurement of nerve length might raise the sensitivity of NCSs for the diagnosis of CTS.

Although some studies measured the burden of caregivers and the factors that influenced their feelings of burden, few studies have measured the quality of life (QOL) for primary caregivers of patients with muscular dystrophy (MD). We assessed the QOL for primary caregivers of patients with MD in South Korea and identified factors associated with caregivers' QOL.Ninety dyads of patients with MD and their primary caregivers were enrolled in this study. The QOL of caregivers of patients with MD was assessed subjectively using the World Health Organization Quality of Life Assessment, Life Brief Form. Caregivers' emotional status was assessed using the Beck Depression Inventory (BDI) and family function level was evaluated using the Family APGAR scale. Patients reported their emotional status using the BDI or the Children's Depression Inventory. The functional levels of patients were evaluated by the modified Barthel Index.Caregivers' QOL was statistically associated with family income, family function, emotional status of patients, level of education, and emotional status of caregivers (P0.05). Caregivers who were employed had a significantly higher QOL than those who were not (P0.05). In multiple regression analyses, emotional and employment status of caregivers was strongly associated with caregivers' QOL.Rehabilitation teams should consider not only the physical factors of patients but also the psychological and demographic factors of primary caregivers of patients with MD.

To investigate the ultrasonographic anatomy of the lower leg for safe and accurate needle placement into the tibialis posterior using the anterior approach.Cross-sectional study.University rehabilitation hospital.Healthy volunteers (N=62; 30 men, 32 women).Not applicable.The safety window (the tibia to the neurovascular bundle) and the depth to the midpoint of the safety window (skin to the tibialis posterior) at the upper third and the midpoint of the tibia were measured with a transverse ultrasonographic scan.The safety window at the upper third of the tibia was significantly larger than that at the midpoint (P.01). The safety window ranged from .64 cm to 2.13 cm at the upper third tibialis point and from .32 cm to 1.30 cm at the midpoint. The depth to the tibialis posterior at the upper third of the tibia was significantly deeper than that in the midpoint (P.01). The depth ranged from 2.47 cm to 4.66 cm at the upper third tibias point and from 2.35 cm to 4.28 cm at the midpoint.Ultrasonography is a useful tool in measuring the safety window and the depth to the tibialis posterior using the anterior approach. Considering the safety window, we suggest the needle placement at the upper third point of tibia rather than that at the midpoint.
