Objective: The present study aimed to compare the isometric strength and endurance of shoulder abduction and internal and external rotation between operated shoulders and nonoperated, contralateral shoulders of patients who underwent reverse shoulder replacement due to unilateral rotator cuff tear arthropathy. Patients and methods: With a diagnosis of cuff tear arthropathy, 41 consecutive patients (mean age of 70.8 years; age range, 57 to 84; 36 females, 5 males) who underwent unilateral reverse shoulder arthroplasty were reviewed based on functional and radiological data. In all cases, cuff tear arthropathy was unilateral and contralateral shoulder was asymptomatic, with normal shoulder function. The average length of follow-up was 34 months (range of 12e67). To assess patients' functional level, the Constant score and the Disabilities of the Arm, Shoulder, and Hand (the Quick-DASH) outcome measure were used preoperatively and at the final examination. The primary outcomes of the present study were measurement of isokinetic strength and endurance of shoulder abduction and internal and external rotation using an isokinetic evaluator. Results: Patients exhibited marked improvement in functional level as reflected by a significant increase in the mean Constant score from 38 preoperatively to 65 at the final follow-up (p ¼ 0.03). The functional improvement was supported by a decrease in the mean Quick-DASH from 64 preoperatively to 26 at the final follow-up (p ¼ 0.018). In the comparison of the isokinetic strength and endurance of shoulder abduction, no statistical difference was observed between operated shoulders and contralateral shoulders (p > 0.05). However; the strength and endurance of internal and external rotation were lower in operated shoulders than in contralateral shoulders (p < 0.05). Similarly, there was no statistically significant difference in comparisons of the durability of abduction (p > 0.05); however, the durability of internal and external rotation were significantly lower in operated shoulders (p < 0.05). Conclusion: In terms of durability and strength of abduction, similar results with the unaffected shoulder may be accomplished; nonetheless, the surgeon should be aware that durability and strength of rotation would be weak. Level of evidence: Level III, Therapeutic Study

Objective: This study aimed to investigate whether isokinetic strength decrease significantly after using volar plating for distal radius fractures and evaluate the pronator quadratus muscle regarding atrophy. Methods: This study took place between 2011 and 2015 and included 18 distal radius fracture patients (group 1) who were treated via volar plating at least one year prior and 14 healthy controls (group 2). All participants were tested isokinetically. Grip strength, radiological evaluation, wrist range of motion, disabilities of the arm, shoulder, and hand and visual analog scale scores were assessed for clinical and functional outcomes. Ultrasonography evaluated the pronator quadratus muscle thicknesses. Results: The peak supination torque (PT) and supination work per repetition (WPT) strength values significantly decreased (p:0.039, p:0.025, respectively). Although we determined an 11% pronation PT deficit and a 19% pronation WPT deficit, neither were significant. In group 1, the pronator quadratus muscle thickness decreased 5.9% ± 13.3 in the radial area and 9.7% ± 10.5 in the interosseous area according with ultrasonography; these results were not statistically significant compared to group 2. All clinical and functional outcomes were not statistically significant between the groups. Conclusion: The use of volar plating after distal radius fractures is a safe method regarding isokinetic strength and pronator quadratus muscle atrophy.

Objectives: This study aims to understand the effectiveness of whole-body vibration (WBV) exercises performed with home exercise program in patients with post-polio syndrome (PPS) in terms of muscle strength, fatigue, the quality of life, and laboratory parameters. Patients and methods: Between October 2015 and March 2016, a total of 14 patients (7 males, 7 females; mean age: 45.1±6.6 years; range, 34 to 57 years) who were diagnosed with PPS were included in the study. The patients were randomized into two groups: the first group received WBV, home exercise program and patient education while the second (control) group received home exercise program and patient education. The patients were evaluated by knee isometric and isokinetic peak torque, Fatigue Severity Scale (FSS), Fatigue Impact Scale (FIS), Nottingham Health Profile (NHP), serum creatine kinase, aspartate aminotransferase, and alanine aminotransferase at baseline and at the end of the treatment. Results: At the end of the treatment, the exercise program administered to the patients was found to be effective in increasing knee muscle strength in PPS patients (p<0.05). This difference was more apparent on the sequela side, isometric extension peak torque in the group with WBV. There was no significant change in the markers of muscle damage or NHP in both groups. Conclusion: Inclusion of WBV in home exercise program in PPS patients does not seem to be superior, except for reducing the effect of fatigue on the patient's life.

Perturbation training is commonly applied; however, its effects on the peroneal muscle remain underexplored in the female basketball player population. This study aimed to investigate the effects of perturbation-based neuromuscular training (PNT) on dynamic balance, peroneal muscle strength, endurance, and functional performance in young female basketball players. A randomized controlled trial was conducted with forty young female basketball players. The players were assigned to either a perturbation-based neuromuscular training group (PG) (n=20) or a control group (CG) (n=20) by simple random allocation. PG received an 8-week neuromuscular training program (two sessions/wk) in addition to routine basketball training, while CG attended routine training only. Dynamic balance, peroneal muscle eccentric strength, endurance, vertical jump (VJ), and side hop (SH) tests were evaluated. Dynamic balance was evaluated with the Y balance test, and peroneal muscle eccentric strength and endurance were evaluated with the Cybex dynamometer. PG demonstrated significant improvements in dynamic balance (p=0.000), VJ (p=0.0049), and SH performance (p=0.010) after the training program, analyzed with analysis of variance. Peroneal eccentric strength significantly increased in PG (p=0.001 right, p=0.020 left). Both groups showed improvements in peroneal muscle endurance parameters; however, the PG group improved significantly (p=0.004 right, p=0.025 left). An 8-week PNT significantly enhances dynamic balance, eccentric eversion strength, and jump performance while contributing to reduced peroneal muscular fatigue in young female basketball players.

Background Fibromyalgia syndrome (FMS) is a chronic disease characterized by diffuse pain, fatigue, sleep disturbance, cognitive impairment, and other physical symptoms that adversely affect physical and sensory functions and impair quality of life. Nowadays, in the treatment of FMS, low intensity aerobic exercises and exercise programs combined with other treatment methods are recommended. Objectives The aim of this study was to evaluate the effects of aerobic and balance-proprioception exercises on the symptoms of Fibromyalgia (FMS) and the superiority of the two exercise models. Methods 51 female patients who adhere to the inclusion criteria were divided into two groups randomly. Aerobic Exercise Group (AEG; n=26) and Balance-Proprioceptive Exercise Group (BPEG; n=25) was applied to the exercise laboratory under the supervision of physiotherapist in Istanbul Medical Faculty, Department of Sports Medicine 3 days a week for 6 weeks. Before and after the program Pain (VAS), functional status (FIQ), postural stability (Biodex balance system), knee joint proprioception (Cybex isokinetic dynamometer) were evaluated. Cognitive status was assessed by Standardized Mini Mental State Examination (SMMSE) only before program. Results There wasnt statistically significant difference between demographic (age, weigh, BMI etc.) and clinic (VAS, FIO, Biodex, Cybex, SMMSE) features of the groups at the beginning (p>0.05). Parameters measured in both groups after exercise programs showed progress compared to initial levels (p0.05). Recovery is found to be superior at BPEG in balance parameters (eyes open overall stability index (EOOSI) and eyes open anterioposterior stability index (EOAPSI)) and some parameters that belongs to proprioception (p<0.05). Conclusion It is determined that aerobic exercise and balance-proprioception exercise programs at/in FMS are effective -in positive way- methods for functionality, pain, proprioception and balance parameter recovery of the patients. Except EOOSI and EOAPSI balance parameter values; according to other parameters it is found that aerobic exercise and balance-proprioception exercises are equal to each other. It is found out that balance-proprioception exercises are superior to aerobic exercises for improving EOOSI and EOAPSI. It is revealed that balance proprioception exercises are more effective for curing proprioception. It is observed that patients with FMS had deterioration in cognitive functions.
