Abstract:
The nature of an experimental trigger point model produced by eccentric exercise was examined in seven healthy volunteers who gave their informed consent. Adjustable loads were set around the third finger and the subjects were asked to keep the position as long as possible. The loadings (about 10s) were continued until his all-out effort and were carried out 3 times interspersed with 5 min rest periods. Pressure pain thresholds (PPT) and deep pain thresholds (DPT) before exercise, and on the 2nd and 7th day after the exercise, were measured in the skin, fascia and muscles. On the 2nd day after the exercise, the PPT of the restricted area of the taut band was the minimum. A similar reduction of the DPT was observed only in the fascia of the restricted area. These results suggest that the present experimental model is useful for the further investigation of trigger points.
