An Analytic Study of Chiropractic High-Velocity Thrust

A thrust in chiropractic is performed mainly by delivering a precise instantaneous thrust. The authors have constructed a model that demonstrates transmission of a directed force by contraction of muscle in the upper arm, using physical equations. Furthermore, we constructed a thrust force measuring apparatus and performed actual measurements. Measurement results have revealed that there was a high correlation between data obtained from the actual measurements and those from obtained from the model. Furthermore, the results suggested that the measuring apparatus can be a device that judges thrust and velocity in future studies.
