RESUMEN

BACKGROUND: Despite advances in hand therapy and surgery, functional deficits persist after flexor tendon repair especially in zone I-III. This suggests that methods applied may be insufficient. Electromyographic (EMG) biofeedback may provide an effective tendon gliding through visual and auditory feedback. PURPOSE: The purpose of this study was to investigate the effect of EMG biofeedback training applied in addition to early passive motion protocol on functional status in zone I-III flexor tendon injuries. METHODS: Patients were randomly assigned into two groups, each consisted of 11 patients. In addition to early passive motion method, EMG biofeedback training was applied in the first group. The second group was followed only with early passive motion protocol. Joint range of motion (ROM), Michigan Hand Outcomes Questionnaire (MHQ) and grip strength were evaluated. RESULTS: There were no significant differences between the groups in terms of the ROM, MHQ scores and grip strength (p ≥ .087). However, there were clinically important differences in the results of the 12th week ROM (effect size = 0.70), 24th week activity of daily living (ADL) score in MHQ (effect size = 0.68), 12th week gross, tip pinch and lateral grip strength (effect sizes = 0.59, 0.52, 0.81, respectively) and 24th week gross, tip pinch and lateral grip strength (effect sizes = 0.69, 0.73, 0.69, respectively) between the two groups. CONCLUSIONS: EMG biofeedback training was clinically but not statistically superior to early passive motion method in terms of the effect on functional status.

RESUMEN

Introduction Hand dexterity is not addressed in patients with distal radius fracture (DRF) accompanied with ulnar styloid fracture (USF) in literature. This study aimed to determine whether an associated USF following a DRF has any effect on hand dexterity. Materials and Methods Patients diagnosed with DRF were included in the study and were divided into two groups according to the USF presence (USF group and non-USF group). Pain, range of motion, Quick-DASH (Quick-Disabilities of the Arm, Shoulder, and Hand), handgrip and pinch strength, Purdue Pegboard test, and Jebsen Taylor Hand Function test were measured in the sixth month. Results A total of 125 patients, 68 females (54.4%) and 57 males (45.6%) were included in the study. The mean age of the patients was 47.15 ± 13.41 (18-65) years. There were 60 patients (48%) in the USF group and 65 patients (52%) in the non-USF group. No significant difference was found in pain, range of motion, Quick-DASH and handgrip and pinch strength between the groups ( p > 0.05). The hand dexterity tests showed no statistically significant difference between the groups in the sixth month ( p > 0.05). Discussion Hand function can be determined more accurately by assessing hand dexterity. In this study, it is emphasized that concomitant USF does not lead to poorer hand dexterity.

RESUMEN

OBJECTIVE: The aim of the study was to investigate the relation between health-related quality of life and risk of falling, fear of falling, and functional status in patients with hip arthroplasty. METHODS: In this cross-sectional study, 48 hips of 45 patients who aged between 33 and 79 (53.56 ± 12.50) years and had cementless total hip arthroplasty between 2010 and 2014 were evaluated. Twenty-seven of the patients participated in the study were female (60.0%) and 18 were male (40.0%). Health-related quality of life with Nottingham Health Profile, function of the hip joint with Harris Hip Score, risk of falling with Performance-Oriented Motion Assessment I, and fear of falling with Falls Efficacy Scale were assessed. In addition, chair stand test, 40-m walk test, stair-climb test, and single leg stance test were carried out. In analysing the relationships between these parameters, Pearson correlation analysis was employed. The level of significance was considered as p < 0.05. RESULTS: Among the cases, who were evaluated 87.10 ± 45.22 (22.43-214.71) weeks after the operation, a significant correlation was found between health-related quality of life and risk of falling, function of hip joint, and functional tests (p < 0.05). CONCLUSION: The evaluation of the factors related to health-related quality of life in hip arthroplasty patients may help identify patient needs and guide the rehabilitation process.

RESUMEN

The purpose of this study is to investigate the disability level, leisure satisfaction, and quality of life in employees who were disabled. Six hundred twenty-seven employees who were disabled were included in this study and classified according to age, gender and disability level. In quality of life, there was significant difference between genders and age groups (p <  .05). There was no significant difference neither in leisure satisfaction nor in disability level between groups (p > .05). In disability assessment, males were better and there was a significant difference in leisure satisfaction (p <  .05). Age, gender, and disability level were important factors affecting disability, leisure satisfaction, and quality of life among employees who were disabled.

RESUMEN

OBJECTIVE: The aim of this study was to investigate the effect of scapular muscle endurance on chronic shoulder pain in textile workers. METHODS: In total, 91 textile workers were divided into two groups based on the presence (n=43) or absence (n=48) of chronic shoulder pain, as assessed using the Nordic Musculoskeletal Questionnaire (NMQ). The endurance of the serratus anterior and trapezius muscles was assessed using the Scapular Muscle Endurance (SME) test. RESULTS: In the group with chronic shoulder pain, mean scapular muscle endurance was significantly lower than that in the pain-free group (t-test, p< 0.05). There was a significant negative correlation between rest - activity pain intensity and SME (Pearson correlation analysis, p< 0.01). CONCLUSIONS: Scapular muscle endurance has an effect on the development of shoulder pain in textile workers.
