OBJECTIVE: To identify potential neuromuscular factors associated with dynamic balance in individuals with @entity626 ( @entity571 ). DESIGN: Cross-sectional observational study; backward stepwise multiple linear regression was used to identify factors associated with dynamic balance in 2 statistical models. SETTING: University clinical research laboratory. @entity1 : Individuals aged >= 50 years (N=52) with osteoarthritic changes on radiograph participated. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Dynamic balance was assessed using the Community Balance and Mobility Scale (CB_M). Potentially modifiable neuromuscular factors associated with dynamic balance were measured, including the sum of concentric and eccentric lower-extremity muscle strength, 2 quadriceps-hamstrings muscle strength ratios, @entity3325 (joint position sense), anticipatory postural control velocity, and knee joint range of motion. RESULTS: The first model for explaining variance in CB_M scores consisted of eccentric lower-extremity muscle strength and knee joint range of motion as factors. The model containing these 2 variables explained 50% of the variance in CB_M scores. The second model adjusted for descriptive variables, including age, body mass index, and knee @entity158 , contained only the neuromuscular variables eccentric lower-extremity muscle strength, and explained 68% of the variance in CB_M scores. CONCLUSIONS: These results suggest that muscle strength and, to a lesser extent, knee joint range of motion are important factors associated with dynamic balance as measured by the CB_M and should be considered in dynamic balance interventions.
