OBJECTIVE: To examine the acute effects of aquatic and land treadmill exercise on gait kinematics as well as the level of disease-specific and movement related pain for individuals with osteoarthritis. DESIGN: Quasi-experimental crossover design. SETTING: Biomechanics laboratory. PARTICIPANTS: Participants (N=14; age, 43-64y) diagnosed with osteoarthritis at the knee (N=12), osteoarthritis at the knee and ankle (N=1), or osteoarthritis at the knee and hip (N=1). INTERVENTIONS: Participants performed three exercise sessions separated by at least 24 hours in one week for each mode of exercise (aquatic treadmill and land treadmill). MAIN OUTCOME MEASURE(S): Gait kinematics and pain were measured before and after each intervention. RESULTS: The angular velocity gain score during stance for left knee extension was improved by 38% after aquatic treadmill exercise (p = 0.004). Similarly, during swing the gain scores for angular velocity were also greater for left knee internal rotation and extension by 65% and 20%, respectively (p = 0.004, p = 0.008). During stance, the joint angle gain score for left hip flexion was 7.23% greater after land exercise (p = 0.007). During swing the angular velocity gain score for right hip extension was significantly greater for aquatic exercise by 28% (p = 0.01). Only the joint angle gain score for left ankle abduction during stance was significantly higher after land exercise (4.72%, p = 0.003). No other joint angle gain scores for either stance or swing were significantly different for either condition (p = 0.06-0.96). Perceived pain was 100% greater following land than aquatic treadmill exercise (p = 0.02). Step rate and step length were not different between conditions (p = 0.31-0.92). CONCLUSION(S): An acute training period on an aquatic treadmill positively influenced joint angular velocity and arthritis related joint pain. Acute aquatic treadmill exercise may be useful as a conservative treatment to improve angular speed of the lower extremity joints and pain related to OA.
