Brief Summary

High-Velocity Low-Amplitude (HVLA) manipulation is a known technique of the Osteopathic Manipulative Treatment (OMT) for somatic dysfunction (SD), and heart rate variability and H-reflex response are possible variables to assess its neurophysiological effects. Somatic dysfunction is an impairment or altered function of related components of the somatic system. Studies show a transient attenuation of α-motor neuron excitability after HVLA manipulation in asymptomatic participants. According to studies, HVLA spinal manipulation increases joint mobility by blocking afferent impulses in the muscle spindle and the small-diameter free nerve, decreasing the γ-motor neuron activity.

Interventions

HVLA manipulation OTHER

participant is laying on the left side, the practitioner stands in front of the participant's abdomen. The practitioner contacts the interspinous space of the L5-S1 level with the caudal; with the cephalic hand, the practitioner rotates the participant's upper body until a sense of tension is palpated at the L5-S1 segment. The practitioner places his cephalic hand at interspinous, brings participant's leg to a flexion and places the foot at the popliteal fossa, places the forearm at the participant's deltopectoral groove and the caudal forearm at the gluteal region. Following the participant's expiration, the practitioner brings the L5-S1 level to the restrictive barrier by rotating the trunk and hips to opposite directions.
