Influence of self-reported physical activity and sleep quality on conditioned pain modulation in the orofacial region.

Objectives: To evaluate the influence of self-reported physical activity and sleep quality on conditioned pain modulation (CPM) in the orofacial region.

Materials And Methods: Ninety healthy participants aged 18-50 years old were evenly distributed according to the level of physical activity into low, moderate, and high level.
