This study analyzed the immediate effects on pressure pain threshold in latent myofascial trigger points in the upper trapezius muscle of a single cervical spine manipulation directed at the C3 through C4 level. The results suggest that a cervical spine manipulation directed at the C3 through C4 segment induced changes in pressure pain sensitivity in latent MTrPs in the upper trapezius muscle. The authors conclude that different therapeutic mechanisms, either segmental or central, may be involved at the same time.
