چکیده

با توجه به اینکه کف پا پایین‌ترین قسمت زنجیرۀ حرکتی بدن را تشکیل می‌دهد و محدودۀ کوچکی از سطح اتکا را برای حفظ تعادل فراهم می‌کند، منطقی به‌نظر می‌رسد که تغییرات بیومکانیکی در محدودۀ سطح اتکا بتواند کنترل تعادل را تحت تأثیر قرار دهد. هدف از تحقیق حاضر بررسی رابطۀ بین نتایج تست Y با دستگاه توزیع فشار کف پایی در ارزیابی تعادل پویای افراد دارای قوس‌هایی با ارتفاع مختلف در کف پاست. 80 فرد واجد شرایط، در قالب افراد دارای کف پای طبیعی (28 نفر)، قوس طولی داخلی افزایش‌یافته (25 نفر) و قوس طولی داخلی کاهش‌یافته (27 نفر)، به‌عنوان آزمودنی انتخاب شدند. برای تشخیص شکل پا از شاخص افت استخوان ناوی و برای ارزیابی تعادل پویا از تست تعادلی Yو دستگاه توزیع فشار به‌صورت همزمان استفاده شد. داده‌ها پس از بررسی توصیفی با استفاده از آزمون ضریب همبستگی پیرسون در سطح 05/0P £ تجزیه‌وتحلیل آماری شدند. نتایج نشان داد که بین نتایج تستY با دستگاه توزیع فشار در ارزیابی تعادل پویای افراد دارای قوس کف ‌پایی با ارتفاع مختلف ارتباط مثبت و معناداری وجود دارد (337/0= r، 002/0=P) و در افراد دارای پرونیشن افزایش‌یافته (138/0= r، 493/0= P)، سوپینیشن افزایش‌یافته (255/0 =r، 218/0= P) و کف پای طبیعی (349/0=r، 06/0=P) ارتباط معناداری وجود ندارد. بنابراین احتمالاً استفاده از تست Y برای ارزیابی تعادل پویا در افراد دارای قوس‌های کف پایی با ارتفاع مختلف از دقت کافی برخوردار نباشد و بهتر است در تحقیقاتی که فاکتور و هدف اصلی آنها ارزیابی تعادل پویاست، از تست‌های جایگزین و با حساسیت بیشتری استفاده شود.
