Randomized Controlled Trial of Dynamic Balance Training in People With Knee Osteoarthritis

The Effect of Dynamic Balance Training on Balance and Physical Function in Those With Knee Osteoarthritis

There is a high prevalence of falls in those with knee osteoarthritis (OA) compared to healthy older adults. Balance is a key element of function that allows individuals to maintain posture and respond to perturbations, and poor balance control, a risk factor for falls, has been noted in those with knee OA. There is a lack of research guiding treatment for balance deficits in knee OA, with interventions aimed at improving balance deficits in those with knee OA having mixed results. Targeted dynamic balance interventions in other patient populations have been shown to significantly improve dynamic balance control and physical function. If results similar to such populations can be achieved, such a program may produce a significant reduction in functional disability in the knee OA population and improve quality of life. The purpose of this study is to examine the effect of a 10-week targeted dynamic balance intervention on dynamic balance and physical function in people with knee OA. This will be a randomized controlled trial (RCT).

Inclusion Criteria:

• age 50 - 80 years (to meet the American College of Rheumatology clinical definition of OA)
• radiographically confirmed knee OA in the medial compartment of the tibiofemoral joint
• predominance of pain/tenderness over the medial (inside) region of the knee

Exclusion Criteria:

• articular cartilage degradation in the lateral tibiofemoral compartment greater than the medial
• inflammatory arthritic condition
• history of knee or hip replacement surgery
• recent use of corticosteroids (oral or via injection, within last 6 months)
• pain originating predominantly from the patellofemoral joint
• inability to ambulate without a gait aid
• non-English speaking
• recent (within 6 months) arthroscopic knee surgery
• significant hip or back pain (limits the ability to perform the testing)
• Neurological, musculoskeletal or other condition that affects movement ability or balance (i.e. stroke, diabetes, Parkinson's, heart attack, multiple sclerosis, fibromyalgia)
