A Study on the Therapeutic Application of EMG Biofeedback in the Alcoholism

For the purpose of the therapeutic application of EMG biofeedback in the alcoholism, the authors investigated the tension-reduction hypothesis and the capability of reducing tension in alcoholics by EMG biofeedback. 21 alcoholics who were admitted to seoul National Mental Hospital from Jan. 1986 to Jun. 1986 and 21 control subjects entered for the experiment. A comparison between alcoholics and control subjects regarding frontalis muscle tension during 5 minutes of baseline recording on the first session was performed to examine the tension-reduction hypothesis indirectly. The data of muscle tension during 5 sessions of biofeedback training in both groups were analyzed to investigate the relative abilities of alcoholic subjects for neuromuscular learning, hypothesizing that alcoholics are less capable of reducing tension by nonalcoholic means than most people. The results were as follows; 1) Alcoholics(2«64±1.41/[J displayed a higher mean baseline level o f frontalis muscle tension than d id nonalcoholics (7.奶土0.44ᄍ) demonstrated by statistically significant difference. 2) Comparing the results of ANOVA by training concfition at each session, a significant difference was found from the 3rd session in alcoholics and from the 4th session in nonalcoholics. 3) Comparing the results of t-test of mean muscle tension between types of three training conditions during each of the 5 sessions, BFXBiofeedback) group had a statistically significant difference in comparison with NF(No feedback) group or FF(False feedback) group in alcoholics and nonalcoholics. 4) The above-mentioned 2nd and 3rd results made it apparent that alcoholics can learn to reduce frontalis muscle tension by EMG biofeedback. 5) Comparision between below 2.0 MV and above 3.0 MW of baseline subgroup in alcoholics was performed, and there was a significant difference in age and duration of enforced abstinence.
