چکیده

مقدمه و اهداف
یکی از آسیب­های دوران سالمندی، آسیب های ناشی از افتادن حین راه رفتن است هدف از تحقیق حاضر بررسی تاثیر شش هفته تمرینات تعادلی بر سازگاری کینماتیک مفاصل ران، زانو و مچ پا  در راه رفتن زنان سالمند بود.
مواد و روش­ها
تحقیق به روش نیمه تجربی انجام شد. بدین منظور20زن سالمند با دامنه سنی 75-60 (84/4±72/67 سال) به روش نمونه گیری در دسترس انتخاب  و از طریق گمارش تصادفی ساده به دو گروه ده نفری کنترل و تمرین تقسیم شدند. سپس از آزمودنی‌های هر دو گروه یک آزمون مشابه پیاده‌روی در یک مسیر هفت متری با سرعت گام برداری مورد دلخواه طی دو جلسه پیش و پس آزمون به فاصله شش هفته از هم گرفته شد. گروه تمرین به طور منظم هفته ای 3 جلسه و در مجموع 18 جلسه تمرینات تعادلی (شامل انواع ایستادن‌ها و راه رفتن‌ها) را بر اساس پروتکل تعیین شده انجام دادند. با استفاده از دستگاهتحلیل حرکتیویژگی‌های کینماتیک راه رفتن شامل دامنه حرکت مفاصل ران، زانو و مچ پا جمع‌آوری و از طریق نرم افزار کرتکس تحلیل شد. داده‌ها با استفاده از تحلیل واریانس مرکب (2 گروه × 2 زمان) تحلیل شدند.
یافته‌ها
 نتایج تحقیق بهبود معنی‌دار در دامنه حرکت مفصل ران (03/0=P) در گروه تمرین در مقایسه با گروه کنترل نشان داد. دامنه حرکتی مفصل زانو (12/0=P) در گروه تمرین، نسبت به گروه کنترل معنی‌دار نبود. تفاوت معنی­داری در دامنه حرکتی مچ پا در دو گروه تمرین تعادلی و کنترل مشاهده نشد(28/0=P).
نتیجه‌گیری
 نتایج نشان داد که سازگاری‌های کینماتیک مفصل ران در زنان سالمند زیر تاثیر شش هفته تمرینات تعادلی قرار می گیرند. بنابراین، مداخله تمرینات تعادلی می تواند رویکرد موثری در بهبود فاکتورهای خطرزا در افتادن و توسعه جابجایی ایمن در جمعیت افراد سالمند باشد.

چکیده [English]

Background and Aim: One of the main causes of death in the elderly is related to the injuries from falls during walking. The aim of the present study was to examine the effect of 6 weeks of balance training on kinematic compatibility of hips, knees, and ankles joints during walking in elderly women.
Materials and Methods: In the current semi-experimental study, 20 elderly women with the age range of 60-75 (67.72± 4.48 ages) were selected based on convenience sampling procedure to participate in the present study. The participants were randomly divided into control and experiment groups. Participants in each group took a walking test in a pre-test session followed by a post-test after 6 weeks .Participants in the experimental group performed the balance training systematically for 3 sessions in a week. Overall, they were trained for 18 sessions of balance training (including various modes of standing and walking) based on the decided protocol. Making use of motion analysis system, Kinematic features of the walking such as range of motion of hip, knee and ankle joints were collected and analyzed using the Cortex software. Repetitive ANOVA (2 × 2) was run for the purpose of data analysis.
Results: The results of the present study showed significant improvement in range of motion of hip joint (p=0.03) in elderly women of the experiment group compared with that in the control group. Although the variables range of motion of knee (p=0.12) and ankle (p=0.28) joints increased in the experiment group, these increases were not significant in comparison with that in the control group.
Conclusion: The results revealed that kinematic compatibility of hip joint in older women is affected by 6 weeks of balance training. Therefore, it can be suggested that this balance training intervention could be an effective approach to ameliorate the risk factors for falls and to promote safer locomotion in elderly community-dwelling women.
