مقایسه اثربخشی تمرینات نوروفیدبک و فراهم‌سازهای محیط تمرین بر تعادل ایستا در مردان ساکن سرای سالمندان

توانایی تعادل یکی از اجزای حیاتی فعالیت های مستقل روزانه در میان سالمندان است. اختلال تعادل یکی از عوامل خطر عمده برای زمین خوردن و عوارض مربوط به آن است. بنابراین هدف از پژوهش حاضر، مقایسه اثربخشی تمرینات نوروفیدبک و فراهم‌سازهای محیط تمرین بر تعادل ایستا مردان ساکن سرای سالمندان بود. پژوهش حاضر از نوع نیمه‌تجربی با طرح پیش‌آزمون-پس‌آزمون با گروه کنترل بود. جامعه آماری پژوهش حاضر شامل مردان سالمند مقیم سرای سالمندان شهر ایلام با دامنه سنی 60 تا 80 سال بود که تعداد 36 شرکت‌کننده با نمونه گیری در دسترس و با در نظر گرفتن معیارهای ورود و خروج انتخاب شدند، و به سه گروه 12 نفری نوروفیدبک، آموزش فراهم سازی های محیط تمرینی و کنترل تقسیم شدند. شرکت کنندگان در مرحله پیش‌آزمون در سه کوشش اقدام به انجام تکلیف تعادل ایستا نمودند. در مرحله مداخله (تمرین)، که به مدت هشت هفته به طول انجامید و شامل سه جلسه 30 دقیقه‌ای در هفته بود، دو گروه آزمایشی به تمرینات مربوطه پرداختند. لازم به ذکر است که در این مدت گروه کنترل به اجرای فعالیت های معمول و روزانه خود پرداختند. مرحله پس‌آزمون دقیقاً پس از آخرین جلسه تمرینی اجرا شد. داده‌ ها به روش تحلیل کوواریانس تک‌متغیری (آنکوا) تحلیل شد که نتایج آن نشان داد که آموزش نوروفیدبک بر بهبود تعادل ایستای (جابجایی قدامی-خلفی و جابجایی مرکزی-جانبی مرکز فشار) مردان سالمند تاثیر معنی داری دارد (0.01>p). همچنین آموزش فراهم‌ سازی محیط تمرین نیز بر بهبود تعادل ایستای (جابجایی قدامیخلفی و جابجایی مرکزیجانبی مرکز فشار) سالمندان مرد تاثیر معنی‌ داری دارد (0.01>p). نتایج آزمون تعقیبی lsd نشان داد که آموزش فراهم سازی‌های محیط تمرینی در مقایسه با آموزش نوروفیدبک اثر بیشتری در بهبودی تعادل ایستای مردان سالمند داشت (0.01>p). با توجه به نتایج پژوهش حاضر به مربیان و متخصصان سالمندی پیشنهاد می شود که بر غنی سازی محیط برای بهبود تعادل سالمندان توجه نمایند.

the comparison of the effectiveness of neurofeedback training and training environment affordance on static balance in men living in nursing homes

balance ability is a crucial component of the independent daily activities among older adults. balance impairment is one of the significant risk factors for falls and its related complications. therefore, the purpose of the current study was to compare the effectiveness of neurofeedback training and training environment affordance on static balance in the elderly ‎men. this was a quasiexperimental study with a pretestposttest control group design. the statistical population of the present study included the elderly men with an age range of 60 to 80 years living in nursing homes in ilam, iran, among whom 36 participants were selected using convenience sampling along with considering the inclusion and exclusion criteria, and assigned into three groups of neurofeedback, training environment affordance and control, each of which had 12 members. participants performed a static balance task in three attempts in the pretest phase. in the intervention phase (practice), which lasted for eight weeks and included three 30minute sessions per week, the member of two experimental groups performed the relevant exercises. it should be noted that during this period, the control group performed their usual daily activities. the posttest phase was conducted exactly after the last training session. data were analyzed by univariate analysis of covariance (ancova), the results of which indicated that neurofeedback training has a significant effect on improving static balance (anteriorposterior displacement and centrallateral displacement of the center of pressure) in the elderly men (p<0.01). besides, training environment affordance had a significant effect on improving static balance (anteriorposterior displacement and centrallateral displacement of the center of pressure) in the elderly men (p<0.01). the results of lsd posthoc test revealed that compared to neurofeedback training, training environment affordance had greater effect on improving static balance in the elderly men (p<0.01). according to the results of the present study, educators and geriatricians are recommended to pay attention to enriching the environment in order to improve the balance of the elderly. references arandagallardo, m., moralesasencio, j. m., de lunarodriguez, m. e., vazquezblanco, m. j., morillaherrera, j. c., rivasruiz, f., toribiomontero, j. c., & cancasanchez, j. c.
