Controlled trial of EMG feedback in muscle contraction headache.

Twenty-eight patients suffering from severe, longstanding muscle contraction headache were randomly assigned to two groups, one receiving electromyographic (EMG) feedback therapy and the other, "most suitable alternative therapy." Headache intensity and severity as well as drug intake were reduced in the feedback group (p less than or equal to 0.01) as opposed to no improvement in the control group. The positive treatment effect in the feedback group persisted through a three-month follow-up period. EMG feedback therapy is effective in the treatment of muscle contraction headache even in its chronic, severe form, which is resistant to traditional treatment methods.
