چکیده

مقدمه و اهداف
هدف مطالعه حاضر بررسی اثر a-tDCS بر شدت درد زنان مبتلا به درد مزمن کمر می­باشد.
مواد و روش‌ها
10 زن مبتلا به کمردرد مزمن در مطالعه حاضر دو سو کور، شم کنترل با طراحی متقاطع (cross over) شرکت کردند. هر یک از شرکت­کنندگان یک جلسه جریان a-tDCS با شدت ‌جریان 3/0 میلی‌آمپر، مدت‌زمان بیست دقیقه و دانسیته جریان MA/CM2 1/0 که بر منطقه M1 و DLPFC به‌طور هم‌زمان اعمال می‌شد، دریافت کردند. شدت درد و آستانه درد بیماران قبل و بعد از درمان و سطح ناتوانی افراد قبل از درمان و یک هفته پس از درمان ارزیابی ‌شد. از آزمون­های شاپیروویلک جهت بررسی توزیع داده­ها و از آزمون تی زوجی برای تحلیل داده‌ها استفاده گردید و مقدار خطای آزمون کمتر از 05/0 در نظر گرفته شد.
یافته‌ها
نتایج حاکی از عدم تاثیر درمان شم و اکتیو بر شدت درد، ناتوانی و آستانه درد این بیماران بودند. میزان تغییرات میانگین‌ها قبل و بعد درمان اکتیو برای شدت درد 9/ 0(72/0p=)، برای میزان ناتوانی 6/5 )07/0p=) و برای آستانه درد 16/0– (1/0P=) است. این مقادیر در درمان شم به ترتیب 4/0، 4/2 و 73/0–با مقدار p بزرگ‌تر از 05/0 است.
نتیجه‌گیری
این روش درمان اثری بر شدت درد زنان مبتلا به کمردرد مزمن نداشت، اگرچه این نتایج ممکن است مربوط به تعداد کم جلسات درمانی باشد.

چکیده [English]

Background and Aims: The present study aimed to investigate the effects of a-tDCS on pain score in women with Chronic Low Back Pain (CLBP).
Materials and Methods: A total of 10 women with CLBP participated in the current double-blind sham-controlled cross-over study. Each participant received one session of a 20-minute, 0.3 mA tDCS with a current density of 0.1mA/cm2 on M1 and DLPFC, concurrently. Pain intensity and electrical pain threshold were assessed immediately prior to and after the treatment. In addition, the disability was assessed before and one week after the treatment. Shapiro-Wilks goodness-of-fit test was used for normality and dependent t-Test was used for data analysis. Values of p ≤ 0.05 were considered as statistically significant.
Results: The results showed no effect of active or sham treatment on the pain intensity, disability, and pain threshold (p>0.05). The mean difference between before and after active treatment were 0.9 (p=0.7) for pain, 5.6 (p=0.7) for disability, and-0/16 for pain threshold (p=0.1). These values were 0.4, 2.4, and -0.73 for sham treatment with p-value greater than 0.05.
Conclusion: The method studied proved to have no significant effect on pain intensity of women suffering from CLBP; however, this finding may be related to the limited sessions of the treatment.
