چکیده

مقدمه و اهداف
امروزه کفش با قابلیت توزیع مطلوب فشار کف پایی باید بدون افزایش فعالیت عضلانی صورت گیرد. هدف تحقیق حاضر مقایسه توزیع فشار کف پایی و فعالیت عضلات منتخب اندام تحتانی بین کفش ویسکوز و کفش فومی رایج بود.
مواد و روش­ ها
در مطالعه نیمه ­تجربی حاضر، 10 مرد سالم شرکت کردند. در این تحقیق کفشی مخصوص دارای مایع با ویسکوزیته معین در کف آن طراحی شد و مورد استفاده قرار گرفت که می­توانست به دنبال گام­برداری از طریق حرکت مایع، بارهای اعمالی را کاهش دهد. به منظور مقایسه کفش فومی EVA به کار گرفته شد. توزیع فشار کف پایی و فعالیت عضلات منتخب اندام تحتانی با استفاده از سیستم توزیع نیروی پدار و سیستم الکترومایوگرافی مورد اندازه­ گیری قرار گرفت. تحلیل داده­های توزیع فشار با استفاده از نرم­افزار پدار-ایکس و در هشت ناحیه مختلف پا و تحلیل الکترومایوگرافی با استفاده از نرم­افزار متلب صورت گرفت.
یافته­ ها
یافته ­ها نشان داد کفش مخصوص ویسکوز توانسته فشار را در نواحی پاشنه، متاتارسال و شست به ­طور معناداری کاهش دهد، هرچند تغییری در فعالیت عضلات به­جز دوقلو به چشم نخورد.
نتیجه ­گیری
به نظر می‌رسد با توجه به یافته­ های تحقیق حاضر، جذب ویسکوز مایع به دنبال گام­برداری توانسته در کاهش فشار و نیرو در نواحی پرفشار طی راه رفتن مؤثر عمل کند و به نظر نمی­رسد انرژی مصرفی در این شرابط افزایش داشته باشد.

چکیده [English]

Background and Aims: The plantar pressure distribution should not cause any change in muscle activity. The aim of the present study was to compare plantar pressure distribution and electrical muscle activity during walking between viscous shoes and EVA shoes.
Materials and Methods: A total of 10 healthy male individuals were recruited in the current quasi experimental study. A special shoe with specific feature of liquid flow was made for this study, which could reduce pressure from damping mechanism. An EVA shoe was also used for comparison as reference shoe. Plantar pressure distribution was measured using Pedar insole system and muscle activity was measured using Myon EMG system. Data analysis was done using Pedar X and ProEMG softwares and in eight regions of foot.
Results: It was found that special shoe with hydrodynamic mechanism could effectively reduce load in rear foot, forefoot, and toe regions but no significant differences were observed in muscle activity between shoes, except for gastrocnemius.
Conclusion: According to the results, damping effect of liquid shoe following impact force can effectively reduce the pressure and force in high risk regions of the foot.
