بررسی رابطه سطح مقطع عضلات فلکسور عمقی گردن ( لانگوس کولی) با سمت درد، درسر درد گردنی با اولتراسونوگرافی

Introduction and objective: cervicogenic headache as asecondary common frequent intermittent headache form, might stem from a cervical musculoskeletal dysfunction.Due to the stability role of deep neck flexor muscles in cervical region and reported their functional dysfunction in chronic neck subjects investigating the potential relationship between the size and pain laterality of the muscle in subjects suffering from cervicogenic headache might reveal further muscle deficits.Methods: a cross sectional single blind study designed to investigate in 47 volunteers (74 cervicogenic headache and 74 healthy controls). Subjects referred from neurologists and physiotherapists utilizing IHS and cervicogenic headache diagnosis criteria. CSA of longus colli in both sides measured in supine position utilizing ultrasonography.Result:No significant difference was found between affected and non affected muscle size in subjects suffering from one side cervicogenic headache (p>/0/0).No difference was found between muscle sizes in cervicogenic headache subjects compare with healthy controls.Discussion and conclusion:No relationship was found between sizes of longus colli muscle in and pain laterality in cervicogenic headache patients.The nature of longus colli muscle as a stability muscle with muscle fiber changes than size changes, potential of fatty infiltration in muscle and multiple innervations might be the cause of our findings Measuring the muscle in level of c0-c6 with no upper cervical root innervations and out of site of cervicogenic headache dysfunction and impairment compensation in long muscle could be the other reasons Key words:cervicogenic headache /size of deep neck flexor muscles
