Effect of whole body vibration exercise on muscle strength and proprioception in females with knee osteoarthritis
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:
- WBV-exercise on a stable platform (VibM; n=17; mean age, 61.5 ± 9.2)
- WBV-exercise on a balance board (VibF; n=18; mean age, 58.7 ± 11.0) or
- 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
Results- Muscle strength increased in VibM vs Con
- Isometric knee-extension increased in VibM vs Con
- TDPM improved in VibF vs Con
- VibM performed better compared to Con
- No effects in the self-reported disease status measures
