Grier, Finlay. The Reduction of Tension Headache
Using EMG Biofeedback and Locus of Control as Predictors.
Doctor of Philosophy (Clinical Psychology), August, 1989,

This study investigates the status of biofeedback
treatment and locus of control (LOC) affiliation on the
reduction of tension headache. Three LOC groups designated
as internals, powerful-other externals and chance externals
(using Wallston and Wallston's, 1978, Multidimensional
Health Locus of Control Scale) were administered an eight
week electromyogram (EMG) frontalis muscle biofeedback
training program using an Autogen 1700 biofeedback unit.
Subjects were 12 female and four male undergraduate students
who had a history of tension headache. Results indicated no
significant difference in frontalis muscle tension between
the beginning and end of sessions in either a biofeedback or
self-control condition for any of the LOC groups. Further,
there was no significant difference among LOC groups in
ability to reduce muscle tension in either the training or
self-control condition. Finally, neither biofeedback
training nor LOC groups were significant predictors of
headache reduction. Extreme within-group variability and
small sample size affected study findings and these and
other implications for future research are discussed.
