Osteoarthritis of the knee, a prevalent condition in older adults, can impact physical function and ability to perform physical activity. This randomized controlled trial examined the effects of a 6‐month self‐efficacy‐based, individually delivered, lower‐extremity exercise and fitness walking intervention with 6‐month follow‐up on physical activity and function. The 26 subjects were mostly older (M = 63.2 years, SD = 9.8), White (83%), obese (BMI M = 33.3, SD = 6.0) women (96%). Physical activity was measured by diaries. Physical function was measured by the 6‐minute walk, Short Physical Performance Battery (SPPB), and WOMAC Physical Function subscale. Exercise self‐efficacy was assessed by a questionnaire. Results showed significant increases in self‐reported performance of lower‐extremity exercise and participation in fitness walking, distance in the 6‐minute walk, and SPPB scores from baseline to 6‐month follow‐up with a trend for improvement in self‐efficacy. Results suggest that the intervention was feasible, acceptable, and improved physical activity and function.
