Abstract:

HVLA thrust techniques generate a force sufficient to cause strong stretching of the restrictive muscle with subsequent generation of adequate tension to stimulate Golgi tendon organs. Movement into the restrictive barrier during HVLA thrust techniques is made possible by the relaxation of the hypertonic muscle initiated by the inverse stretch reflex mediated by the Golgi tendon organs. In addition, there is a concomitant contraction of the antagonist muscle via excitatory connections of the lb fibers with motor neurons supplying the antagonist muscle.
