Stochastic resonance whole body vibration reduces musculoskeletal pain: A randomized controlled trial

World J Orthop. 2011 Dec 18;2(12):116-20. doi: 10.5312/wjo.v2.i12.116.

Abstract

Aim: To examined the effects of stochastic resonance whole-body vibration training on musculoskeletal pain in young healthy individuals.

Methods: Participants were 43 undergraduate students of a Swiss University. The study was designed as a randomized controlled trial (RCT) with randomized group allocation. The RCT consisted of two groups each given 12 training sessions during four weeks with either 5 Hz- Training frequency (training condition) or 1.5 Hz Training frequency (control condition). Outcome was current musculoskeletal pain assessed in the evening on each day during the four week training period.

Results: Multilevel regression analysis showed musculoskeletal pain was significantly decreased in the training condition whereas there was no change in the control condition (B = -0.023, SE = 0.010, P = 0.021). Decrease in current musculoskeletal pain over four weeks was linear.

Conclusion: Stochastic resonance whole-body vibration reduced musculoskeletal pain in young healthy individuals. Stochastic resonance vibration and not any other exercise component within training caused pain reduction.
