OA Clinic-Community CARE Model

For the WOMAC total score, the test questions are scored on a scale of 0-4. The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. The overall WOMAC score is determined by summing the scores for all three subscales and the score ranges include 0-96 (derived from a 0-4 Likert scale), with higher scores indicating worse pain, stiffness, and functional limitations.

The WOMAC Pain Subscale is a measure of lower extremity pain. It includes 5 items rated on a Likert scale of 0 (no pain) to 4 (extreme pain), with a total range of 0-20 with higher scores indicating worse symptoms and function.

The WOMAC function subscale includes 17 items rated on a Likert scale of 0 (no difficulty) to 4 (extreme difficulty), with ranges of 0-68 for the function subscale with higher scores indicating worse symptoms and function.

Minutes of moderate to vigorous intensity physical activity (MVPA) per week measured via accelerometer.

This measure was log transformed because raw data did not meet assumptoms for statsitical models.

Minutes of any PA measured via accelerometer. This measure was standardized to a 16 hour day to address between-patient differences in amount of wear time.

Self-Reported Physical Activity will be assessed using the Modified version of the CHAMPS (Community Health Activities Model Program for Seniors) Physical Activity Measure. Data from the questionnaire is used to determine variety, frequency, and minutes per week from physical activity. Separate scores are derived for physical activities of moderate or greater intensity (metabolic equivalents MET ≥ 3.0) and for all activities listed (light, moderate, and vigorous). Estimates of frequency (days per week) range from 0 to 7 days per week. Estimates of Variety (# different activities), while open, generally ranges from 0 to 5, values above 5 are checked. Estimates of minutes, generally range from 0 to 180 per day. Individuals reporting more than 180 minutes per day are checked. For all physical activity outcomes higher values equal a greater amount of activity. This measure was square root transformed becuase raw failed to meet assumptions for statistical analyses.

Body weight assessed using a research / clinical grade scale (e.g., Tanita) that will be calibrated regularly.

Assessed to test participant leg strength and endurance. Measured by total number of chair stands (up and down equals one stand) completed in 30 seconds.

Assessed to measure participant functional mobility. Measured by how many seconds it takes for participant to stand up, walk to the mark, turn around, return & sit back into a chair with their back resting on the back of the chair.

Assessed to evaluate participant functional aerobic endurance. Measured by number of steps completed in 2 minutes.
