Manual Therapy and Quality of Life in People with Headache: Systematic Review and Meta-analysis of Randomized Controlled Trials.

People with headache usually experienced significantly lower health-related quality of life (HRQoL) than the healthy subjects. The goal of this systematic review was to evaluate the effectiveness of manual therapy on HRQoL in patients with tension-type headache (TTH), migraine (MH) or cervicogenic headache (CGH).
