مقايسه تأثير دو روش تمريني بر بهبود توانايي عملكرد بيماران مبتلا به مولتيپل‌اسكلروزيس

مقدمه و اهداف امروزه توجه خاصي به اهميت و ضرورت ورزش هوازي در گروه بيماران مبتلا به ام.اس (مولتيپل ­اسكلروزيس) شده است؛ از ­اين ­رو، تحقيق حاضر به بررسي تاثير دو روش تمريني بر توانايي عملكرد (اندام تحتاني، توانايي هماهنگي دست و سر و توانايي عملكرد شناختي) بيماران مبتلا به ام.اس پرداخته است. مواد و روش­ ها در تحقيق حاضر 45 زن 20 تا 40 ساله مبتلا به ام.اس انتخاب شدند و به صورت تصادفي در سه گروه قرار گرفتند؛ دو گروه به مدت 12 هفته و هفته ­اي سه روز به تمرين تردميل حمايتي و دوچرخه ثابت پرداختند و گروه كنترل زندگي معمول خود را گذراندند. تست توانايي عملكرد (تست­هاي زمان 25 گام برداشتن، قرار دادن 9 ميخ در سوراخ، جمع كردن متوالي شنيداري) در پيش ­آزمون و پس­آ زمون از افراد گرفته شد. به ‌منظور آزمون فرضيه‌هاي پژوهش از ANCOVA و MANCOVA استفاده شد. يافته‌ها يافته ­هاي تحقيق حاضر نشان داد تفاوت آماري معني‌داري بين ميانگين تعديل‌شده عملكرد توانايي گروه‌ تمرين با دوچرخه ثابت و گروه‌ تمرين با تردميل حمايتي مشاهده نشد (0/05p)، اما تفاوت آماري معني‌داري بين ميانگين تعديل‌شده مولفه­هاي گروه‌ تمرين با دوچرخه ثابت و گروه‌ تمرين با تردميل حمايتي مشاهده نشد (0/05

Background and Aims: During the recent years, attention has been paid to the importance of aerobic exercises in MS (Multiple sclerosis) patients. Therefore, the present research studies the effect of two methods of training on the functional ability (lower limb, hand and head coordination ability, and cognitive ability) of patients with MS. Materials and Method: In the current research, 45 women with MS, aged 20-40 years old, were randomly assigned to three groups. The two groups continued to practice supportive treadmill and fixed bike for 12 weeks, 3 days a week, and the control group received no training. Functional ability test (25 time steps, 9 nails in the hole, consecutive acoustic scans) were taken from the participants in the pre-test and post-test. ANCOVA, and MANCOVA were run to test the hypotheses. Results: There was no significant difference between the moderated mean performance of the training group with the supportive treadmill and fixed bike (p> 0.05). In order to investigate the effect of MANCOVA analysis of covariance training on post-test scores, the functional abilities components were tested. The average of moderated components of lower limb function, hand and head coordination ability, and cognitive ability of exercise groups with fixed bike and exercise with supportive treadmill were significantly higher than those of the control group (p <0.05). However, there was no significant difference between the moderated means of the components of the fixed bike and the supportive treadmill (P> 0.05). Conclusion: According to the results, both supportive treadmill training and fixed bike are effective in improving lower limb function, hand and head coordination ability, and cognitive ability of people with multiple sclerosis.
