Frontalis EMG of dropouts from inpatient treatment for alcoholism.

Nineteen of 61 male alcoholic inpatients who had agreed to participate in a research study requiring them to undergo 20 electromyographic (EMG) biofeedback sessions left the treatment center before completion of the treatment program. Dropouts and remainers did not differ in initial EMG levels but early dropouts had significantly higher levels than late dropouts. There was a statistically significant difference in intellectual and educational level in favor of the remainers. Implications for treatment planning are discussed.
