چکیده
مقدمه: هدف از پژوهش حاضر بررسی اثر آنی تردمیل گوه‌ای محقق ساخته بر میزان فعالیت عضلات منتخب اندام تحتانی افراد دارای کف پای صاف بوده تا با فعال‌سازی عضلات، جهت کمک به حیطه حرکات اصلاحی و اصلاح کف پای صاف و توان‌بخشی و پیشگیری از آسیب مورداستفاده قرار بگیرد.

مواد و روش­ها: پژوهش حاضر باتوجه ‌به ساخت و معرفی ابزاری جدید و بررسی اثر آن مداخله‌ای و از نوع نیمه‌تجربی بود. 16 فرد بالای 18 سال مبتلا به ناهنجاری کف پای صاف وارد این مطالعه شدند. ناهنجاری کف پای صاف با استفاده از شاخص استاهلی ارزیابی شد. آزمودنی‌ها پروتکل راه‌رفتن با سرعت معمولی بر روی تردمیل گوه‌ای محقق ساخته را در هرکدام از زوایای جانبی صفر، 5 و 15 درجه به مدت‌90 ثانیه، انجام دادند و فعالیت الکترومایوگرافی پنج عضله منتخب در تمام زوایا ثبت شد. تجزیه‌وتحلیل داده‌ها با نرم‌افزارهایMatlab و SPSS انجام شد و به منظور بررسی معناداری اثر زوایا از آزمون فریدمن و از آزمون تعقیبی بونفرونی برای مقایسه دو به دو میانگین‌ها استفاده شد.

یافته‌ها: براساس نتایج، میانگین فعالیت عضلات منتخب (پرونئوس لانگوس، تیبیالیس انتریور، گستروکنمیوس، سولئوس و هالوسیس) حین راه‌رفتن بین زوایای 5 و 15 درجه بر روی تردمیل گوه‌ای در مقایسه با صفر درجه اختلاف معنادار آماری داشتند (05/0p≤).

نتیجه‌گیری: نتایج ما پیشنهاد می‌دهد که با استفاده از تردمیل گوه‌ای محقق ساخته و راه‌رفتن در زوایای 5 و 15 درجه، می‌توان سطح فعالیت عضلات منتخب اندام تحتانی افراد دارای کف پای صاف را به میزان معناداری افزایش داد.

Background and Aims: The current study aims to investigate the immediate effect of a researcher-made wedge treadmill on the activity of the selected lower limb muscles of flat feet individuals, so by activating the muscles, it can be used to help in the area of corrective exercise and correction of flat feet, rehabilitation and injury prevention.

Methods: The current study was a semi-experimental intervention based on the creation and introduction of a new tool and its effect evaluation. 16 subjects over 18 years old with flat feet deformity were included in this study. The subjects performed the protocol of walking at a normal speed on the researcher-made wedge treadmill at each of the lateral angles of 0, 5 and 15 degrees for 90 seconds. The electromyographic activity of five selected muscles was recorded at those angles. Statistical analysis was performed on Matlab and SPSS software. Friedman's test was used to evaluate the significant differences between angles and Bonferroni's post hoc test was used to compare two-by-two means.

Results: According to the results, the average activity of selected muscles (peroneus longus, tibialis anterior, gastrocnemius, soleus and hallucis longus) during walking between angles of 5 and 15 degrees on a wedge treadmill had a statistically significant difference compared to 0 degrees (P≤0.05).

Conclusion: This study showed that the amount of muscle activity of the lower limbs of subjects with flat feet during walking at 5 and 15-degree lateral angles has a significant difference compared to the same people walking at a zero-degree angle. Our results suggest that using the researcher-made wedge treadmill can significantly increase lower limb muscle activity in people with flat feet.
