چکیده
مقدمه: امواج مغزی در بیماران مبتلا به اختلال اضطراب به شکل نابهنجاری فعالیت می­کنند. پژوهش حاضر با هدف تعیین اثربخشی تحریک مکرر مغناطیسی فراقشری بر فعالیت مغزی و اضطراب در بیماران مرد مبتلا به اختلال اضطراب فراگیر انجام شد.
مواد و روش­ها: در این پژوهش نیمه­آزمایشی، جامعه آماری، مردان مبتلا به علایم اختلال اضطراب فراگیر مراجعه­کننده به مراکز روانپزشکی شهر تبریز در سال 1403 (تعداد تقریبی 200) بودند. تعداد 30 نفر به صورت هدفمند انتخاب و به روش تصادفی به دو گروه مساوی آزمایش و کنترل تقسیم شدند. گروه­ها، از نظر امواج بتا و تتا منطقه PZ و شدت اضطراب ارزیابی شدند. گروه آزمایش به مدت 30 جلسه، تحت درمان (مداخله در ناحیه پشتی جانبی قشر پیش­پیشانی نیمکره چپ) قرار گرفت. برای گروه کنترل مداخله­ای انجام نشد. داده­ها توسط آمار توصیفی و آزمون تحلیل کوواریانس چندمتغیره تحلیل گردید.
یافته ­ها: میانگین و انحراف معیار نمره پیش­آزمون و پس­آزمون اضطراب گروه آزمایش 34/3±53/39 و 98/3±76/27 (001/0>p) و گروه کنترل 75/3±36/38 و 71/3±32/38 بود (47/0>p). میانگین و انحراف معیار نمره پیش­آزمون و پس­آزمون بتا PZ گروه آزمایش 56/4±12/43 و 23/3±19/39 (001/0>p) و گروه کنترل 34/4±54/42 و 76/4±65/43 محاسبه شد (71/0>p). میانگین و انحراف معیار نمره پیش­آزمون و پس­آزمون تتا PZ گروه آزمایش 65/2±19/11 و 56/44±2/5 (001/0>p) و گروه کنترل 12/2±75/10 و 73/2±29/11 بود (12/0>p).  
نتیجه­ گیری: به­نظر می­رسد تحریک مکرر مغناطیسی فراقشری بر فعالیت مغزی و اضطراب بیماران تأثیرگذار باشد. بنابراین، می­توان از تحریک مکرر مغناطیسی فراقشری به عنوان درمانی مؤثر برای کاهش اضطراب در بیماران مبتلا به اختلال اضطراب فراگیر استفاده نمود.

چکیده English

Introduction: Studies have shown that brain waves in anxious patients operate abnormally. The present study was conducted with the aim of determining the effectiveness of repetitive transcortical magnetic stimulation on brain activity and anxiety in male patients with generalized anxiety disorder.
Materials and Methods: In the present quasi-experimental study, the statistical population was all male patients with symptoms of generalized anxiety disorder referred to psychiatric centers in Tabriz in 2024, approximately 200 men. Both experimental and control groups were evaluated in terms of beta and theta waves of the PZ region and also the severity of anxiety, and then the experimental group was treated for 30 sessions. The intervention was performed in the dorsolateral region of the left prefrontal cortex. The control group did not receive any intervention. Descriptive statistics and multivariate analysis of covariance were used to analyze the data.
Results:The mean and standard deviation of the pre-test and post-test anxiety scores of the experimental group were 39.53±3.34 and 76.27±3.98, respectively (p<0.001) and for the control group they were 38.36±3.75 and 38.32±3.71, respectively (p<0.47). The mean and standard deviation of the pre-test and post-test beta PZ scores of the experimental group were 43.12±4.56 and 39.19±3.23, respectively (p<0.001) and for the control group they were 42.54±4.34 and 43.65±4.76, respectively (p<0.71). The mean and standard deviation of the pre-test and post-test PZ theta scores of the experimental group were 11.19±2.65 and 56.44±2.5, respectively (p<0.001) and for the control group they were 10.75±2.12 and 11.29±2.73, respectively (p<0.12).
Conclusion:It seems that repetitive transcortical magnetic stimulation can affect brain activity and anxiety in patients. Therefore, repetitive transcortical magnetic stimulation can be used as an effective treatment for reducing anxiety in patients with generalized anxiety disorder.
