Brief Summary

This a cross-over study to compare the effect of two different muscle energy techniques (MET) including post-isometric inhibition and reciprocal inhibition on the spinal reflex excitability. The study contains two experimental groups, while one group will receive post-isometric inhibition MET in the first stage and reciprocal inhibition MET in the second stage, the other group will receive reciprocal inhibition MET in the first stage and post-isometric inhibition MET in the second stage.

Conditions

Relaxation; Joint; Limitation, Mobility; Relaxation; Lumbosacral

Keywords

Spinal Reflex Excitability; Muscle Relaxation; H reflex

Outcome Measures

Primary Outcomes (2)

• Change in H Reflex Amplitude

  H reflex or Hoffman's reflex is a refectory reaction of muscles after electrical stimulation of sensory fibers (Ia afferent from muscle spindles) in their innervated nerves (here is Tibial N),

  First measurement (Base-line), second measurement after 30 minutes (Pre-test), third measurement after 20 minutes (first post-test), forth measurement after 20 minutes (second post-test)

• Change in M wave Amplitude

  M- wave is a compound muscle action potential, which is produce by the electrical stimulation of motor nerve fibers (here is Tibial N)

  First measurement (Base-line), second measurement after 30 minutes (Pre-test), third measurement after 20 minutes (first post-test), forth measurement after 20 minutes (second post-test)

Study Arms (2)

Experimental RI-PI

EXPERIMENTAL

They receive the Reciprocal Inhibition (RI) technique in the first stage and then the Post-isometric Inhibition (PI) technique in the second stage.

Other: Reciprocal Inhibition Muscle Energy Technique; Other: Post-Isometric Inhibition Muscle Energy Technique

Experimental PI-RI

EXPERIMENTAL

They receive the Post-isometric Inhibition (PI) technique in the first stage and then the Reciprocal Inhibition (RI) technique in the second stage.

Other: Reciprocal Inhibition Muscle Energy Technique; Other: Post-Isometric Inhibition Muscle Energy Technique

Interventions

Reciprocal Inhibition Muscle Energy Technique OTHER

In this technique, the subject will be asked to contract antagonist muscles against a moderate resistant force provided by the therapist to inhibit the contraction of the agonist muscle.

Experimental PI-RI; Experimental RI-PI

Post-Isometric Inhibition Muscle Energy Technique OTHER

In this technique, the subject will be asked to contract agonist muscles against a moderate resistant force provided by the therapist to inhibit the contraction of the agonist muscle.
