چکیده

مقدمه و اهداف
طیف فرکانس نیروهای عکس­العمل زمین یکی از پارامترهای مکانیکی است که با استفاده از آن می­توان با مقایسه افراد سالم و بیمار تفاوت­ها را برجسته کرد. هدف از مطالعه حاضر مقایسه طیف فرکانس نیروهای عکس­العمل زمین در افراد ناشنوا و سالم طی دویدن بود.
مواد و روش ­ها
پژوهش حاضر از نوع نیمه­تجربی بود. 30 پسر به طور مساوی به دو گروه با شنوایی عادی و ناشنوا تقسیم شدند. طیف فرکانس نیروهای عکس­العمل زمین  توسط دستگاه فوت اسکن (نرخ نمونه­برداری: 300 هرتز) ثبت شد. سپس محتوای فرکانسی نیروهای عکس­العمل در طی دویدن با پای برهنه تحلیل گردید. از آزمون آماری واریانس چندمتغیره جهت مقایسه داده­های طیف فرکانس نیروهای عکس­العمل زمین طی دویدن در افراد ناشنوا و سالم استفاده شد.
یافته ­ها
نتایج تحقیق حاضر نشان داد تعداد هارمونی­های ضروری در انگشت شست پا (012/0=P) و انگشتان 2 تا 5 (035/0=P) در افراد ناشنوا در مقایسه با گروه کنترل کمتر بود. همچنین تعداد فرکانس با توان 5/99 در استخوان کف پایی چهارم (038/0P=) و پنجم (019/0P=) در افراد ناشنوا در مقایسه با سالم بیشتر بود. به علاوه زمان اتکای دویدن در افراد ناشنوا در مقایسه با سالم بیشتر بود (032/0=P).
نتیجه­ گیری
با توجه به نتایج پژوهش حاضر می­توان بیان کرد افراد ناشنوا احتمالا در معرض آسیب ناشی از مقادیر طیف فرکانس نیروهای عکس­العمل زمین طی دویدن قرار دارند.

چکیده [English]

Background and Aims: The frequency domain analysis of ground reaction forces is one of the mechanical parameters that can be distinguished by comparing the differences between healthy and patient groups. The purpose of the current study was to compare the frequency domain analysis of ground reaction forces in deaf and healthy control people during running.
Materials and Methods: The present study was a quasi-experimental design. A total of 30 male individuals were equally divided into two groups of normal hearing and hearing loss (Deaf group). Peak plantar pressure variables in deaf people and healthy control were recorded using a foot scan system (sample rate: 300 Hz). The multivariate ANOVA test was used to compare the ground reaction force frequency domain data during running in deaf and healthy participants.
Results: The results showed that frequency content with the number of essential harmonies in the Toe area (P= 0.012) and fingers 2 to 5 (P=0.035) in deaf was smaller than that of healthy control group. Also, the frequency content with power of 99.5% in the fourth metatarsal (P=0.038) and fifth metatarsal (P=0.019) in deaf group was greater than that of healthy control ones. Stance time during running was more in deaf group than in healthy control group (P=0.032).
Conclusion: According to the results of the present study, it can be stated that deaf people are likely to be exposed to the damage caused by the ground reaction force frequency domain during running.
