Effect of Otago exercises on some functional characteristics, fear of falling an‎d quality of life in female patients with MS

آسيب شناسي و حركات اصلاحي

Multiple sclerosis is an autoimmune, chronic an‎d progressive disease of the nervous system that causes disturbances in balance, coordination, increased risk of falls an‎d muscle weakness in individuals. In recent years, sports science studies have emphasized the use of exercise to improve the disorders of this disease. The aim of the present study was to study the effect of Otago exercises on some functional characteristics, fear of falling an‎d quality of life of female patients with MS. Methods: In this semi-experimental study, 28 women with multiple sclerosis referring to the Isfahan MS Association were selec‎ted to participate in the study through convenience an‎d purpose. The mean an‎d stan‎dard deviation of the subjectsʹ age was 70.57±42.70, the Expan‎ded Disability Status Scale was 0.84±2.23, the height was 162.85±33.5, an‎d the weight was 64.92±43.9. They were ran‎domly assigned (EDSS score) to two control (n=14) an‎d experimental (n=14) groups. The experimental group performed the Otago exercise program (for the whole body, with four levels of difficulty from easy to difficult) for 8 weeks, 3 sessions per week for 30 to 45 minutes. While the control group received their usual care an‎d daily activities. Before an‎d after the training intervention, the variables of static balance, dynamic balance, cardiorespiratory endurance, neuromuscular function, range of motion, proprioception, muscle strength, quality of life, fatigue, fear of falling, an‎d fear of movement were eva‎luated through the functional access test, time to get up an‎d go, 6-minute walk, an‎d 30-second sit-to-stan‎d from a chair, goniometer, dynamometer, 54-question quality of life questionnaire, MFIS questionnaire, FSI questionnaire, an‎d Tampa questionnaire for patients with multiple sclerosis, respectively. The combined analysis of variance (Repeated Measure) test was used to analyze the data. Also, the significance level was determined at the 95% confidence level (P≤0.05). Results: The functional capacity of the experimental group was significantly improved compared to the control group in the time to get up an‎d go, 6-minute walk, 30-second sit-to-stan‎d from a chair, an‎d functional access tests at the post-test (P≤0.05). There was a significant difference in the range of motion only in the left hip joint, but no significant difference was seen in the other joints (P≥0.05). There was no significant difference in the reconstruction error at angles of 60 degrees an‎d 30 degrees in either leg (P≥0.05). However, a decrease in the reconstruction error at 60 degrees an‎d 30 degrees was observed in the experimental group compared to the control group. In the variable of muscle strength, a significant difference was seen in some muscles of the lower extremities (P≤0.05), but no significant difference was seen in some other muscles (P≥0.05). Also, a significant improvement was seen in the quality of life of the experimental group compared to the control group at the post-test (P≤0.05). There was no significant difference in the fear of falling (P≥0.05). In the fear of movement, a significant difference was seen only in the fall variable of the fear of movement questionnaire (P≤0.05), an‎d no significant difference was seen in the other variables (P≥0.05). There was no significant difference in the fatigue factor (P≥0/05). Conclusion: Otago exercises are a multifaceted, safe, an‎d low-cost intervention that can significantly improve functional capacity an‎d quality of life in patients with MS in a short period of time.
