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.
