چکیده

مقدمه و اهداف
آسیب ویپلش در اثر افزایش و کاهش شتاب در گردن به دنبال تصادف، افتادن و یا ضربه اتفاق می­افتد. از آن جایی که عضلات اکستانسور گردن، نقش مهمی در تحرک و تامین ثبات گردن به عهده دارند، آسیب آن­ها می­تواند در تداوم و پیشرفت عوارض تاثیر بسزایی داشته باشد. هدف از مطالعه حاضر مقایسه تغییرات اندازه و شدت بازتاب عضلات اکستانسور گردن در بیماران با آسیب ویپلش و افراد سالم می­باشد.
مواد و روش‌ها
مطالعه تحلیلی-مقطعی حاضر بر روی 10 فرد سالم و 10 بیمار مبتلا به آسیب ویپلش که بیماری آنها توسط متخصص نورولوژی و یا ارتوپدی تایید شده بود، انجام شد. شدت درد، نمره پرسش­نامه شاخص ناتوانی درد (NDI)، قطر قدامی-خلفی و شدت بازتـاب عضلات ابلیک کپیتیس، رکتوس کپیتیس پوستریور، سمی اسپاینالیس کپیتیس، اسپلنیوس کپیتیس، لویتور اسکپولا و تراپز فوقانی اندازه­گیری و ثبت شد.
یافته­ ها
مطالعه حاضر نشان داد که ضخامت عضلات رکتوس کپیتیس و ابلیک کپی تیس بیماران در مقایسه با افراد سالم کمتر بود (0.05p<). شدت بازتاب نرمالایز­شده عضله رکتوس کپیتیس به طور معناداری در بیماران کمتر از افراد سالم بود(0.05p<).
نتیجه­ گیری
نتایج مطالعه حاضر نشان داد که عضلات اکستانسور بخش فوقانی گردنبیماران مبتلا به ویپلش از نظر ضخامت باریک­تر و از نظر شدت بازتاب کمتر از افراد سالم بود. تغییرات عضلانی فوق ممکن است  به طور موثری از علل مرتبط با تداوم ضعف و کاهش آستانه تحمل ساختارهای گردنی در بیماران مبتلا به صدمات ویپلش باشد.

چکیده [English]

Background and Aims: Whiplash injury occurs due to acceleration-deceleration in neck following the accidents. Since neck extensor muscles play a crucial role in mobility and stabilization of neck, their injury might significantly affect continuation and progress of complications. The objective of the present study was to investigate the variations of size and echo intensity of neck extensor muscles in patients suffering from whiplash injury and healthy individuals.
Materials and Methods: An analytical-sectional study was carried out on 10 healthy persons and 10 patients suffering from whiplash injury whose disease had been confirmed by neurologists and/or orthopedists. Pain severity, neck disability index (NDI) questionnaire score, anterior-posterior diameter, and echo intensities of oblique capitis, posterior rectus capitis, semi-spinalis capitis, splenius capitis, levator scapula, and upper trapezius were measured and recorded.
Results: The present study indicated that thicknesses of rectus capitis and oblique capitis muscles in the patients were smaller as compared with those of the healthy individuals (p<0.05). Normalized echo intensity of the rectus capitis muscle was significantly lower in patients compared with the healthy individuals (p<0.05).
Discussion and Conclusion: The present study demonstrated that extensor muscles of the upper part of neck in the patients suffering from whiplash injury are narrower in terms of thickness and less severe in terms of echo intensity as compared with those of the healthy individuals. The abovementioned muscular alterations are effectively among the reasons associated with continuation of weakness and reduction in tolerance threshold of neck structures in the patients suffering from whiplash injuries.
