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 .
Does hydrotherapy improve strength and physical function in patients with osteoarthritis--a randomised controlled trial comparing a gym based and a hydrotherapy based strengthening programme.
OBJECTIVE To compare the effects of a hydrotherapy resistance exercise programme with a gym based resistance exercise programme on strength and function in the treatment of osteoarthritis ( OA ) . DESIGN Single blind , three arm , r and omised controlled trial . SUBJECTS 105 community living participants aged 50 years and over with clinical OA of the hip or knee . METHODS Participants were r and omised into one of three groups : hydrotherapy ( n = 35 ) , gym ( n = 35 ) , or control ( n = 35 ) . The two exercising groups had three exercise sessions a week for six weeks . At six weeks an independent physiotherapist unaware of the treatment allocation performed all outcome assessment s ( muscle strength dynamometry , six minute walk test , WOMAC OA Index , total drugs , SF-12 quality of life , Adelaide Activities Profile , and the Arthritis Self-Efficacy Scale ) . RESULTS In the gym group both left and right quadriceps significantly increased in strength compared with the control group , and right quadriceps strength was also significantly better than in the hydrotherapy group . The hydrotherapy group increased left quadriceps strength only at follow up , and this was significantly different from the control group . The hydrotherapy group was significantly different from the control group for distance walked and the physical component of the SF-12 . The gym group was significantly different from the control group for walk speed and self efficacy satisfaction . Compliance rates were similar for both exercise groups , with 84 % of hydrotherapy and 75 % of gym sessions attended . There were no differences in drug use between groups over the study period . CONCLUSION Functional gains were achieved with both exercise programmes compared with the control group
