SUMMARY In this study we used quantitative surface electromyography (SEMG) for the evaluation of dystonic muscles in cervical dystonia to evaluate whether quantitative SEMG can be used as a diagnostic tool for cervical dystonia or not. Root mean square (RMS), mean rectified value (MRV), mean frequecy (MF), turns per second (T/S), mean amplitude (MA) and ratio of turn number to mean amplitude were the parameters used for the quantitative evaluation of SEMG of the sternocleidomastoid (SCM) muscle and posterior neck muscles esspecially splenius capitis (SC) muscle in 22 patients not treated with botulinum toxin. 11 healthy subjects were examined for comparison. RMS, MRV, MF, T/S, MA and T/A values of normal SCM muscles during maximal voluntary contraction (MVC) were statistically higher than the values of the dystonic SCM muscles at the resting position. At the comparison of normal and dystonic SCM muscles during MVC; RMS, MRV, T/S values of normal SCM muscles were statistically higher than dystonic SCM muscles. There was no statistical difference at MF, MA and T/A values of the same muscle groups during MVC. RMS, MRV, T/S, MA and T/A values were statistically higher during MVC of dytonic SCM muscles compaired to the resting position. There was no statistical difference at the MF value of the same muscle group at the same conditions.All the values for SC muscle were considered as unreliable because of the anatomical localization of that muscle. It is concluded that MF might be most reliable parameter in the evaluation of cervical dytonia.We suggest that one should choose superficial muscles like SCM muscle for investigation to obtain reliable values of quantitative SEMG. 62
