Effects of Stochastic Whole-body Vibration Training on Balance and Executive Functions

Immediate Effects of Stochastic Whole-body Vibration Training on Balance and Executive Functions: A Randomized Controlled Trial

Falls represent a significant financial burden, costing millions of dollars annually in Switzerland (SUVA, 2022). Good cognitive abilities and good balance represent modifiable protective factors against falls (Kurz, 2008). The present study investigates the impact of stochastic whole-body vibration training (SR-WBV) on executive functions and balance. To this end, participants were randomized into an intervention group or a control group. Participants in the intervention group underwent SR-WBV at a frequency of 5 Hertz (Hz), while participants in the control group underwent SR-WBV at 2 Hz. The training on an SRT Zeptor® Medical plus noise device consisted of three one-minute intervals of vibration, interspersed with one-minute rest periods. Data on executive functions (Updating, Shifting, Inhibition) and balance were collected before and after the intervention , complemented by subjective assessments of concentration and balance through questionnaires.
