Objective: To investigate a new style of resistance exercise using elastic bands and explore its therapeutic effect on the lower-extremity function of female patients with osteoarthritis (OA) of the knee. Design: A randomized, controlled clinical trial. Setting: University-affiliated medical center. Participants: Forty-one women with mild-to-moderate knee OA were randomly assigned to one of two groups, an exercise group (n24; age: 65.0±8.4 years), and a control group (n17; age: 70.8±8.4 years). Interventions: The exercise group performed supervised exercise with elastic bands in addition to conventional modality treatments two to three times a week for 8 weeks. The control group received only the conventional modality treatments over the same period. Main outcome measures: The distance of the functional forward-reach, 30 s chair stand repetitions, walking function (time of a 10 m walk, timed up-and-go, and going up-and-down 13-stair tests), and Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index scores. Results: Statistically significant improvements in all measures were observed in the exercise group after 8 weeks (p
