fa اثربخشی تحریک الکتریکی فراجمجمه ای مغز بر بهبود توجه دیداری و شنیداری در افراد دارای نشانگان نقص توجه و بیش فعالی تخصصي Special پژوهشي Research <strong>هدف.</strong> پژوهش حاضر با هدف اثربخشی تحریک الکتریکی مستقیم فراجمجمه ای مغز بر بهبود توجه دیداری و شنیداری در افراد مبتلا به بیش فعالی و نقص توجه شهر تهران صورت گرفته است. <strong>روش.</strong> این پژوهش شبه آزمایشی و به صورت پیش آزمون-پس آزمون با گروه کنترل انجام شد. جامعه آماری پژوهش را کلیه افراد مبتلا به بیش فعالی و نقص توجه شهر تهران در سال 1396 تشکیل می دادند که تعداد 30 نفر به عنوان حجم نمونه تعیین گردید. از جامعه آماری تعداد 15 نفر در گروه آزمایش و 15 نفر کنترل&nbsp; با روش نمونه گیری در دسترس و به صورت تصادفی انتخاب و گمارش شدند.برای گروه آزمایش مداخله تحریک الکتریکی مستقیم فراجمجمه ای مغز انجام شد.&nbsp; ابزار جمع‌آوری اطلاعات شامل پرسشنامه وندریوتا و تکلیف کامپیوتری اجرای همزمان دیداری و شنیداری <span dir="LTR">(IVA)</span>بود. برای تجزیه و تحلیل داده ها از آزمون کوواریانس تک متغیره و چندمتغیره استفاده شد. <strong>یافته ها.</strong> نتایج تحقیق پس از مداخله نشان داد بین گروه های آزمایش&nbsp; و کنترل در متغیر توجه (دیداری و شنیداری) تفاوت معنی داری وجود دارد. <strong>نتیجه گیری</strong>. بنابراین می توان گفت تحریک الکتریکی مستقیم فراجمجمه ای مغز در بر بهبود توجه دیداری و شنیداری در افراد مبتلا به بیش فعالی و نقص توجه موثر است<span dir="LTR">.&nbsp;</span> <strong>Objective:</strong> The purpose of this study was to investigate the effect of <a href="https://en.wikipedia.org/wiki/Transcranial_direct-current_stimulation">Transcranial direct-current stimulation</a>on the improvement of visual and auditory attention in People with attention deficit-hyperactivity disorder(ADHD)in Tehran. <strong>Method:</strong> This research was supposed as an&nbsp; quasi-experimental one and it was carried out by using a pre-test and post-test method with the control group<span dir="RTL">.</span> The statistical population of the study consisted of all individuals who suffer from attention deficit-hyperactivity disorder in Tehran in 1396.
