VIBRATION FOR REPAIR

​

Benedetti MG Boccia G et al. Int J Rehabil Res. 2017 Jul 18 High frequency vibration, but not electrostim, improved physical function and reverses hypotrophy of quadriceps.

Effect ... on hand function in patients with distal radius fractures.Imaie R, Osumi M et al. Clin Rehabil. 2017 May;31(5):696-701

“[Tendon vibration] was an effective post-surgery management strategy not only for pain alleviation, but also hand function in patients with distal radius fractures...improvements persisting for up to two months.”

WHY VIBRATION AND CRYOTHERAPY TOGETHER

​

Cryotherapy reduces inflammation but also persistently reduces blood flow. Vibration vasodilates, cancelling the vasoconstriction effect while adding pain relief and separating muscle fibers to reduce stiffness. An increased number
of residual cross-bridges between myosin heads and actin is thought to largely contribute to this exercise-induced increased stiffness (Proske and Morgan, 2001) which vibration addresses. Why vibration instead of electrostim
Electrostim doesn’t increase blood flow, because it is the pulsatile vibration that mimics rapid heart rate, releasing nitric oxide and vasodilating. Electrostim doesn’t cause muscle twitching in the amplitude and frequency that actual
motion does. J Athl Train. 2012 Sep-Oct;47(5):498-506.

This is probably because electrostim doesn’t promote hormonal repair gene expression.
