Hypoalgesic Effect of Cervical Manipulation

Hypoalgesic Effects of Specific vs Non-specific Cervical Manipulation in Healthy Subjects

This study evaluates the hypoalgesic effect of global and specific cervical joint manipulation in healthy individuals. At first the participants received one of the interventions and after 48 hours, the other.

Cervical Joint Manipulation (CJM) are often used for pain treatment.

Joint manipulation generates a series of stimuli within the central nervous system through the activation of proprioceptors located in the joint capsule or muscles, stimulates the PAG, causing pain inhibition by activation of non-opioid descending inhibitory pathways.
