CONCLUSION strength training , Tai Chi and aerobics exercises  improved balance and falls risk in older individuals with knee OA , while water-based exercises and light treatment did not significantly improve balance outcomes .
Strength training , Tai Chi and aerobics exercises can therefore be recommended as falls prevention strategies for individuals with OA .
INTRODUCTION osteoarthritis ( OA ) of knee has been reported as a risk factor for falls and reduced  balance in the elderly .
This systematic review evaluated the effectiveness of physical therapies in improving balance and reducing falls risk among patients with knee OA .
Effect of whole body vibration exercise on muscle strength and proprioception in females with knee osteoarthritis.
The purpose of this study was to assess the effect of whole body vibration ( WBV ) exercise on muscle strength and proprioception in female patients with osteoarthritis in the knee ( knee-OA ) . A single blinded , r and omised , controlled trial was performed in an outpatient clinic on 52 female patients diagnosed with knee-OA ( mean age 60.4 years+/-9.6 ) . They were r and omly assigned to one of 3 groups : 1 . 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 ) ) . The WBV groups trained twice a week for 8 weeks , with a progressively increasing intensity . The WBV groups performed unloaded static WBV exercise . The following were measured : knee muscle strength ( extension/flexion ) and proprioception ( threshold for detection of passive movement ( TDPM ) ) . Self-reported disease status was measured using WOMAC . It was found that muscle strength increased significantly ( p<0.001 ) in VibM compared to Con . Isometric knee-extension significantly increased ( p=0.021 ) in VibM compared to Con . TDPM was significantly improved ( p=0.033 ) in VibF compared to Con , while there was a tendency ( p=0.051 ) for VibM to perform better compared to Con . There were no effects in the self-reported disease status measures . This study showed that the WBV-exercise regime on a stable platform ( VibM ) yielded increased muscle strength , while the WBV-exercise on a balance board ( VibF ) showed improved TDPM . The WBV-exercise is a time-saving and safe method for rehabilitation of women with knee-OA
