Overview

This is a small, pilot, pre/post evaluation study enrolling older Hispanic American adults with moderate knee arthritis to evaluate the feasibility of recruitment, retention and adherence after a multimodal 12-week, physical therapy intervention. The secondary aim is to evaluate preliminary estimates of change on physical performance and health related quality of life after the intervention.

Background: Hispanic Americans (HAs) experience more pain and mobility deficits associated with knee osteoarthritis (OA) compared to non-Hispanic whites (NHWs) and seek total knee arthroplasties at a reduced rate, thus conservative treatments are needed. Prevalence of knee OA among the older HA population is rising dramatically. There is moderate evidence that lower extremity strengthening, manual therapy and self-management training improve pain and physical performance in people with knee OA and little evidence in the HA population. We conducted a pilot prospective trial implementing a multimodal high intensity targeted strength training, manual therapy and self-management education intervention to evaluate feasibility of recruitment, retention and adherence and preliminary estimates of change on physical performance and health related quality of life (HrQOL) in HAs with moderate knee OA. If this trial is feasible and shows promise for efficacy, it may warrant further testing as a primary treatment for knee OA. Methods: Spanish speaking older adults will be recruited from Kaiser Permanente San Francisco through a medical record search. Participants will attended 10 physical thearpy clinic visits over 8 weeks, followed by 4 weekly phone calls to assess adherence to exercise via 1-week verbal recall. Participants will be instructed to exercise 3 days per week for the study duration combining both clinic and home exercise participation. The intervention is led in Spanish and will include progressive open and closed-chain quadriceps and gluteal strengthening, progressive cycling training with short power intervals, manual therapy and self-management training.

Outcomes

Primary Outcomes

Number of participants enrolled in the study

Number of participants enrolled in to the study to determine ability to recruit for the study.

Time frame: 12 weeks

Percentage of enrolled participants at end of study

Number of participants who complete the study divided by the number who enroll in the study to determine retention.

Time frame: 12 weeks

Average number of completed exercise session per-week for the study duration.

Number of clinic session attendance plus the number of self-reported participation in home exercise divided by the study goal of exercising 3 days per week for the 12 week study duration (36 exercise sessions total) yielding a percentage to determine adherence to the exercise intervention.

Time frame: 12 weeks

Secondary Outcomes

Change in Five-times Sit to Stand (5TSTS) from baseline to after the intervention.

5TSTS is a physical performance measure and is the time in seconds it takes for participants to stand up and sit down from a chair 5 times as fast as possible. Shorter duration in seconds indicates improved physical performance.

Time frame: 12 weeks

Change in Six-minute Walk Test (6MWT) from baseline to after the intervention.

6MWT is a physical performance measure and is the distance in meters participants are able to walk for 6 minutes at self-selected speed. Shorter distance in meters indicates improved physical performance.

Time frame: 12 weeks

Change in Timed Up and Go (TUG) from baseline to after the intervention.

Timed up and go (TUG) is a physical performance measure and is measured in seconds, the time it takes for participants to rise from a chair, walk 10-meters at their 'normal' speed and return to a sitting position. Shorter duration in seconds indicates improved physical performance.
