Effect of whole body vibration exercise on muscle strength and proprioception in females with knee osteoarthritis
The Knee, 06/10/09

Trans T et al. – Study shows that the whole body vibration (WBV)-exercise regime on a stable platform (VibM) yielded increased muscle strength, while the WBV-exercise on a balance board (VibF) showed improved threshold for detection of passive movement (TDPM).

Methods

Study to assess the effect of WBV exercise on muscle strength and proprioception in female pts with knee-OA
52 female pts; mean age: 60.4 yrs; randomly assigned to one of 3 groups:
1. WBV-exercise on a stable platform (VibM; n=17; mean age, 61.5 ± 9.2)
2. WBV-exercise on a balance board (VibF; n=18; mean age, 58.7 ± 11.0) or
3. Control group (Con; n=18; mean age, 61.1 ± 8.5)
WBV groups trained twice a wk for 8 wks, with a progressively increasing intensity
WBV groups performed unloaded static WBV exercise
Knee muscle strength (extension/flexion) and proprioception TDPM were measured
Self-reported disease status was measured using WOMAC
