The vibration is considered an innovative feature in the treatment of chronic low back pain and herniated disc as many musculoskeletal effects are noticed from this . According to Silva (2011) for exposure to vibration, it is possible that the muscles produce a force about 15 times higher than that produced in normal conditions, in order to oppose the action of gravitational force . Cardinale and Bosco (2003 ) stated that the vibration causes changes in muscle length , so in an attempt to mitigate this effect , the afferent influence the motor response , causing modulation of muscle stiffness . According to Bishop cited Barbosa (2009 ) in response to stimulation of the muscle spindle is an isometric contraction known as the tonic vibration reflex ( RTV ) , which is accompanied by a reciprocal inhibition of the antagonist and blocking myotatic reflex .
