چکیده

مطالعة حاضر با هدف بررسی اثربخشی تحریک موزون شنیداری حین تمرین راه‌رفتن بر برخی شاخص‌های کینماتیکی گام‌‌برداری بیماران مبتلابه مالتیپل اسکلروزیس انجام شد. 18 بیمار مبتلا (چهار مرد و 14 زن) با درجة ناتوانی سه تا شش به شیوة نمونه‌گیری دردسترس و هدفمند انتخاب شدند و به‌طور تصادفی در دو گروه تجربی و کنترل قرار گرفتند. تمرینات به‌مدت سه هفته، سه جلسه در هفته و هر جلسه 30 دقیقه انجام شدند. این تمرینات برای گروه تجربی، راه‌رفتن با محرک موزون شنیداری و برای گروه کنترل، راه‌رفتن بدون هرگونه محرک بود. قبل و بعد از تمرینات، طول قدم، زمان قدم، مدت زمان استقرار و مدت زمان نوسان توسط دستگاه تجزیه‌وتحلیل حرکتی اندازه‌گیری شدند. تحلیل داده‌ها با استفاده از مدل آنالیز کوواریانس و روش ناپارامتری بوت استرپ در مدل آنالیز کوواریانس انجام شد. یافته‌ها نشان داد که تحریک موزون شنیداری بر بهبود طول قدم و مدت زمان استقرار اثر معنا­داری دارد (0.05> P).تمرین راه‌رفتن با محرک موزون شنیداری به 27 درصد بهبودی در زمان قدم و 10 درصد در مدت‌ زمان نوسان منجر شد؛ اما بین دو گروه تجربی و کنترل تفاوت معناداری در بهبود زمان قدم و مدت‌ زمان نوسان یافت نشد (0.05<P)؛ بنابراین، تحریک موزون شنیداری حین تمرین راه‌رفتن را می‌توان به‌عنوان یک روش درمان تکمیلی با هدف بهبود عملکرد گام‌‌برداری بیماران مبتلا به مالتیپل اسکلروزیس پیشنهاد کرد.

چکیده [English]

The aim of this study was to investigate the effect of rhythmic auditory stimulation during gait training on some kinematics parameters of gait in patients with multiple sclerosis. 18 patients with MS (4 males and 14 females) with Expanded Disability Status Scale scores of 3 to 6 were selected by accessible and purposive sampling method. Patients were randomly assigned to two experimental and control groups. Training was performed for three weeks, three times a week and each session 30 minutes. These Trainings for the experimental group included gait with rhythmic auditory stimulus and for the control group included gait without stimulus. Before and after training, step length, step time, duration of stance and duration of swing were measured by motion analysis device. data were analyzed using covariance analysis model and boot strap non-parametric method in covariance analysis model. Findings showed rhythmic auditory stimulation has significant effect on improvement of step length and duration of stance. Nevertheless gait training with rhythmic auditory stimulus leads to 27% improvement in step time and 10% in duration of swing, but there was no significant difference between the experimental and control groups in improvement of step time and duration of swing. Therefore, gait training with rhythmic auditory stimulation supposed as a complementary rehabilitation method to improve gait function in patients with multiple sclerosis.
