Placebo-controlled evaluation of abbreviated progressive muscle relaxation and of relaxation combined with cognitive therapy in the treatment of tension headache.

Abstract

Sixty-six tension headache patients were randomly assigned to one of four conditions for 8 weeks: (a) progressive muscle relaxation (PMR) alone; (b) PMR plus cognitive therapy (PMR + Cog); (c) pseudomeditation, a credible attention-placebo control; or (d) continued headache monitoring. A comparison of overall headache activity (headache index), derived from a daily headache diary, for 4 weeks before treatment to 4 weeks after treatment, revealed that active treatment (PMR and PMR + Cog) was superior to either control condition. Moreover, level of headache medication consumption decreased significantly for the active treatment groups. Although headache-index comparisons of the two active treatments showed no advantage for adding cognitive therapy to PMR, a measure of clinically significant change showed a trend for PMR + Cog to be superior to PMR alone.
