چکیده
مقدمه و اهداف
همواره دردهای کمری و ناهنجاری ­های وضعیتی یکی از مهمترین موضوعاتی است که در محیط کاری مطرح است. در این بین کارمندانی که ماهیت کار آنها ایستا و در حالت نشسته به­مدت طولانی است، بیشتر دچار این عوارض خواهند شد که با راهکارهایی می­توان این مشکلات را کاهش داد و احتمالا از بین برد؛ بنابراین هدف پژوهش حاضر بررسی تأثیر 6 هفته تمرینات صندلی بر روی متغیرهای کینماتیکی در حین راه رفتن، ساختار بدنی و درد کارمندان دانشگاه شهید باهنر کرمان می‌باشد.
مواد و روش ­ها
پژوهش حاضر از نوع نیمه ­تجربی است که جامعه آماری آن دانشگاه شهید باهنر کرمان می‌باشد و نمونه آماری آن 27 نفر شامل 10 مرد و 17 زن (سن: 51/4±81/40 سال، قد: 47/8±15/164 سانتی‌متر، جرم: 75/6±18/75  کیلوگرم) است که به‌صورت هدفمند انتخاب‌ شده‌اند. متغیرهای طول گام، عرض گام و تواتر گام­برداری با استفاده از سیستم سه­بعدی Motion Analysis با 6 دوربین اپتوالکترونیک با فرکانس ثبت 120 هرتز اندازه‌گیری شد. برای اندازه‌گیری لوردوز از خط‌کش منعطف، ﺷﺎﻧﻪﺑﻪﺟﻠﻮ از چهارگوش دوگانه و برای سنجش میزان درد از پرسشنامه نوردیک استفاده شد. جهت تجزیه­وتحلیل داده‌ها از روش آماری تی وابسته در سطح معنا‌داری 05/0>P استفاده شد.
یافته ­ها
یافته‌های پژوهش حاضر بیانگر آن بود که بین میانگین‌های پیش‌آزمون و پس‌آزمون تفاوت معناداری برای متغیرهای طول گام، عرض گام، تواتر گام، درد کمری، لوردوز و ﺷﺎﻧﻪﺑﻪﺟﻠﻮ وجود داشت و اندازه طول گام در پس­آزمون افزایش یافته است و اندازه سایر متغیرها کاهش یافته است.
نتیجه ­گیری
با توجه به یافته‌های تحقیق کنونی، نتایج بیانگر آن است که تمرینات صندلی تأثیر مثبتی بر متغیرهای کینماتیکی، کاهش لوردوز کمری و ﺷﺎﻧﻪﺑﻪﺟﻠﻮ و همچنین کم کردن درد کمری کارمندان دارد که بر این اساس می‌توان از این تمرینات در راستای بهبود متغیرهای کینماتیکی، ساختار بدنی و کاهش درد در ناحیه کمر استفاده کرد.

چکیده [English]

 Background and Aims: Lumbar pain and postural abnormalities are among the most important issues in the workplace. In the meantime, staffs with a static and steady state of work will be more likely to suffer. In case of proper solutions, these problems can be reduced and possibly eliminated. Therefore, the purpose of the present study was to examine the effect of six weeks of chair exercises on the kinematics variables during walking, physical structure, and pain among the staffs at Shahid Bahonar University of Kerman.
Materials and Method: A quasi-experimental study was carried out at Shahid Bahonar University of Kerman. A sample of 27 people including 10 males and 17 females (age: 40.81 ± 4.51 years, height: 164.15±8.47 centimeters, mass: 75.18 ± 6.75 kg) selected purposefully took part in the study. The step length, step width, and step frequency were measured using a 3D Motion Analysis system with 6 optoelectronic cameras and a recording frequency of 120 Hz. To measure lordosis, a flexible ruler was used and to measure pain, forward shoulder from a double quadrilateral and Nordic questionnaire was used. To analyze the data, dependent t-test was used at the significance level of P Results: The results revealed significant differences between pretest and posttest averages for these variables: stride length, step width, frequency step, back pain, shoulder lordosis, and shoulder forward. Also, the length of the step size increased in the post-test. The size of other variables, however, declined.
Conclusion: According to the results of the present study, chair exercises have a positive effect on the kinematic variables, the reduction of lumbar lordosis, and forward shoulder, as well as the reduction of the lumbar pain in the staffs. Accordingly, these exercises can be used to improve the kinematic variables, body structure, and pain relief in the lumbar region.
