Context: Muscle weakness and sensory deficits cause impaired balance and walking abilities that are prerequisites for independent activity of daily living in people with multiple sclerosis (MS). Recent physical exercises tailored to improve the activity of daily living people with MS have focused on the functional training. Objective: To investigate the effect of total body resistance exercise suspension training on mobility, proprioception, and muscle strength of the knee in people with MS. Design: Single-blind pretest and posttest control group design. Setting: Referral Center of Multiple Sclerosis Society. Participants: Thirty-four women with relapsing–remitting MS were participated in this study. The mean (SD) of their age was 36.44 (4.88) years, and the Expanded Disability Status Scale was 2.35 (0.94). The participants were divided into 2 groups: control group (n = 15) and training group (n = 19). Intervention: The training group performed the total body resistance exercise program for 8 weeks, 3 sessions per week. The control group received their usual care and daily activities. Outcomes were measured presessions and postsessions. Main Outcome Measures: Mobility was assessed with Timed Up and Go test, 10-m walk maximum test, 2 minute walk test, and 5-time sit-to-stand test. Knee proprioception absolute error and isometric strength of knee flexor and extensor muscles were measured by using a biodex isokinetic dynamometer. Results: In the training group, mobility (P = .001), maximal voluntary isometric contraction of knee flexor and extensor muscles in both legs (P > .05), and the knee proprioception absolute error in nondominant leg at 60° knee flexion (P = .02) improved significantly compared with the control group. Conclusion: Total body resistance exercise is a functional and safe intervention that can improve the mobility and muscles strength of the knee in a short period in people with MS.
Purpose: Firefighters require a high level of functional fitness to operate safely, effectively, and efficiently. The authors studied the distribution of functional movement screen (FMS) scores in firefighters and examined whether an 8-week corrective exercise program based on National Academy of Sport Medicine guidelines could improve them. Methods: All 524 active firefighters of a city completed the baseline FMS testing. Those who obtained a score of 14 or less, a sign of movement dysfunction, and volunteered to continue their participation were randomly assigned to either an experimental (n = 51) or a control (n = 45) group. Both groups participated in an 8-week training program. The control group used their own usual training routine, but the experimental group used the specific protocol designed for the study. Results: The FMS scores of 43% of the population were less than 14. Repeated-measures analysis of variance revealed a significant interaction between FMS scores of the groups (F1,94 =165, P < .001). The experimental group showed a 69% improvement from pretest (10.6) to posttest (17.8), whereas the control group showed only a 3% improvement from pretest (11.8) to posttest (12.1). Conclusions: Preceding studies have shown that FMS scores less than 14 increase the injury risk. The findings showed that using our proposed training protocol, low FMS scores could be improved to 14 and higher. Considering the high injury rate of firefighters, the authors suggest administering FMS periodically and to use a training protocol such as ours, to increase functional fitness and reduce injury risk.
The results of this study confirmed that rebound therapy could reinforce the static stability of SCI individuals during motionless standing. It suggests that rebound exercise is a useful sports rehabilitation method for patients with SCI and other wheelchair-bound individuals.
Background: Patients with chronic renal failure suffer physical and physiological constraints as a result of the hemodialysis process and lack of mobility. The aim of this study was to investigate the effects of selected core stability exercises on the pain, fatigue and physical performance in elderly hemodialysis patients.Methods: In this quasi-experimental study, 30 hemodialysis man patients with a mean age (62.246.51 years), history of dialysis (29.418.44 months) and dialysis three times a week were selected by available manner and randomly were divided into exercise (n=15) and control group (n=15). Pain, fatigue and physical performance of the patients was measured before and after the training program with VAS questionnaire, FSS questionnaire and two minute walk tests. Patient in the experimental group were done modified core stabilization exercises for 6 weeks, 45minute three sessions in week. To analyze the data, variance analysis was used to measure the repeated values at the significance level (p0.05).Results: The results indicated that the changes and interactions of the two variables of pain (F=24.61, P=0.001), Fatigue (F=41.03, P=0.001) and the physical function (F=83.07, P=0.001) were significant in the experimental group after exercise. Also in the experimental group, showed significant improvement in the pain, fatigue and physical performance (p<0/05), compared to the control group. Conclusion:According to mobility constraints and aggravation of patients' problems in sport strategies based on lower extremity, the selected core stability exercises were an effective and suitable option for elderly hemodialysis in reducing the pain, fatigue and improving physical function, this type of exercise can be used as a non-pharmaceutical strategy by therapists and care staff.
Background and Objectives: The elderly individuals undergoing hemodialysis have lower quality of life compared to their healthy counterparts due to the complications associated with treatment and sedentary lifestyle. The present study aimed to investigate the effects of selected core stability exercises on restless legs syndrome and quality of life in the elderly patients undergoing hemodialysis. Methods: In this quasi-experimental study, a total of 30 patients undergoing hemodialysis with the mean age of 62.24±6.51 years and the mean hemodialysis duration of 29.4±18.44 months, were selected using the purposive convenience sampling method and were randomly assigned to two groups of experimental and control (each 15 subjects). To assess the restless legs syndrome and the quality of life, (RLS) and Kidney Disease Quality of Life Short Form (KDQOL-SF) questionnaires, were used. The experimental group performed selected core stability exercises for 6 weeks (three 45-minute sessions per week). Data analysis was carried out using analysis of variance statistical test at the significance level of p<0.05. Results: Changes and interactions in both variables of restless legs syndrome (p<0.001) and quality of life (p<0.001) was significant in the posttest compared to the pretest in the experimental group. Moreover, a significant improvement was observed in the experimental group compared to the control group in the restless legs syndrome and quality of life (p<0/05). Conclusion: Based on the obtained results, the care staff of dialysis centers can recommend the core stability exercises as a safe and functional strategy to improve restless legs syndrome and quality of life in the elderly patients undergoing hemodialysis.
