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 3 exercise sessions separated by at least 24 hours in 1
week for each mode of exercise (aquatic treadmill and land treadmill). MAIN
OUTCOME MEASURES: 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=.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=.004, P=.008, respectively). During stance, the joint angle gain score for
left hip flexion was 7.23% greater after land exercise (P=.007). During swing,
the angular velocity gain score for right hip extension was significantly greater
for aquatic exercise by 28% (P=.01). Only the joint angle gain score for left
ankle abduction during stance was significantly higher after land exercise
(4.72%, P=.003). No other joint angle gain scores for either stance or swing were
significantly different for either condition (P=.06-.96). Perceived pain was 100%
greater after land than aquatic treadmill exercise (P=.02). Step rate and step
length were not different between conditions (P=.31-.92). CONCLUSIONS: 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 osteoarthritis.
