Abstract

EMG abnormalities such as short muscle twitches and marked increase of muscle tone can be identified during REM sleep. We compared the polysomnographic parameters of ten alcoholic patients who were sober and medication-free for at least four weeks, five methadone-substituted politoxicomanic patients (MSP) and ten healthy control patients. The alcoholics and the MSP showed significantly more twitches than the control patients, and the MSP had significantly more tonus increase than the alcoholics and the controlled. The polysomnographic measures differed significantly between the groups in sleep architecture. The alcoholics had significantly less slow-wave sleep (SWS) and more REM sleep, the MSP had a longer REM latency and more of stage 2. Dividing all subjects along the median of the two EMG abnormalities, the group which showed a high number of twitches had significantly less SWS with a compensatory increase of stage 2. The two EMG measures, which were scored additionally, may provide a useful additional information in the differentiation of sleep disturbances in alcoholic and methadone-substituted patients. The interaction between the occurrence of these EMG abnormalities and the other polysomnographic measures in our study needs further clarification.
