Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Through an observational, cross-sectional study, muscle activity was compared among 21 subjects with episodic headache, 17 subjects with chronic headache and 17 age-matched healthy controls. Muscle activity was bilaterally tested with needle electromyography at rest status, targeting at myofascial trigger points (MTrPs) in the frontal, temporal, sternocleidomastoid (SCM), splenius capitis, splenius cervicis and trapezius of each subject. Headache characteristics (intensity, frequency and duration), McGill Pain Questionnaire (MPQ) and Digital Span (DS) scales were secondary outcomes. The correlation between muscle activity and headache characteristics was also analyzed.

This study provides preliminary evidence of the relationship between muscle and the chronicity of headache.
