چکیده

هدف پژوهش بررسی ارتباط قدرت عضلات اندام تحتانی و دامنه حرکتی فعال مچ پا با وضعیت تعادل ایستا و پویای ناشنوایان ورزشکار و غیرورزشکار و مقایسه این متغیرها در این افراد بود.
30 نفر از نوجوانان ناشنوای مادرزادی عمیق و شدید شهر مشهد در دو گروه همگن ناشنوایان ورزشکار و غیرورزشکار مورد بررسی قرار گرفتند. وضعیت کنترل تعادل ایستا و پویای نمونه ها توسط دستگاه تعادلسنج بایودکس، قدرت اندام تحتانی به وسیله دینامومتر و دامنه حرکتی فعال مچ پا به وسیله گونیامتر اندازه گیری شد.نتایج تحقیق نشان داد بین قدرت عضلات پلانتارفلکسور مچ پا با تعادل ایستا و تعادل پویا، بین قدرت عضلات بازکننده ران با تعادل ایستا و پویا و بین دامنه حرکتی فعال مچ پا با تعادل ایستا و پویا در دو گروه ارتباط معنادار وجود دارد. همچنین بین دو گروه در متغیرهای قدرت اندام تحتانی، تعادل ایستا و تعادل پویا تفاوت معناداری وجود داشت.

چکیده [English]

The aim of this study was to investigate the relationship between lower extremity strength and active range of motion of the ankle with static and dynamic balance in deaf athletes and non-athletes and compare them. 30 adolescent boys with congenital sever deafness were recruited according to the study inclusion and exclusion criteria and allocated into athlete and non-athlete groups. A Biodex Stability System, dynamometer and goniameter used. The results revealed that the athlete deaf subjects showed significantly better static and dynamic balance when compared to non-athletes deaf and significant difference between lower extremity strength (ankle plantar flexor and hip extensor muscles strength) of athlete and non-athlete deaf. There was a significant relationship between lower extremity strength and ankle active ROM with static and dynamic balance.
It seems that higher strength of hip extensor and plantar flexor muscles in deaf athletes resulted in better static and dynamic balance.
