The goal of this study is to evaluate a telehealth Stepped Exercise Program for Knee OsteoArthritis (STEP-KOA) among rural veterans. Methods: This is a single arm, pre-post pilot trial of the 6-month STEP-KOA program among rural Veterans with a physician diagnosis of knee OA who self-report knee pain ≥3 on a 0-10 scale and self-reported difficulty with either walking or stair climbing. We aim to enroll 20 Veterans in this project but may enroll up to 30 in order to obtain sufficient information to evaluate the program, particularly among Veterans who live in very rural areas. Assessments will be conducted via a combination of telephone and video at baseline and 2-, 4-, and 6-month follow-up. Assessments will include questionnaires related to pain, function and physical activity, as well as several physical performance tests. STEP-KOA begins with a low cost, primarily self-directed exercise program (supported by an internet-based tool; Step 1). Patients are then assessed for degree of improvement in symptoms, and then can step up sequentially to telephone or video-based physical activity coaching (Step 2) and physical therapy (Step 3) if they do not make clinically relevant improvements in prior steps. For this project, patients will be assessed approximately every 2 months to determine step progression. Participants will advance to the next step if they do not meet response criteria for pain and function established by the Outcome Measures in Rheumatology group and the Osteoarthritis Research Society International (OMERACT-OARSI). The Step 2 intervention involves bi-weekly telephone or video calls. Step 3 involves 3 telehealth PT visits, based on standard care for knee OA.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Stepped Exercise for Knee Osteoarthritis | Experimental | Patients start with a home-based exercise program, supported by an internet-based tool (Step 1). Patients are then assessed for degree of improvement in symptoms, and then can step up sequentially to telephone or video-based physical activity coaching (Step 2) and physical therapy (Step 3) if they do not make clinically relevant improvements in prior steps. |

| Stepped Exercise for Knee Osteoarthritis | Behavioral | Patients start with a home-based exercise program, supported by an internet-based tool (Step 1). Patients are then assessed for degree of improvement in symptoms, and then can step up sequentially to telephone or video-based physical activity coaching (Step 2) and physical therapy (Step 3) if they do not make clinically relevant improvements in prior steps |
| Measure | Description | Time Frame |
|---|---|---|
| Western Ontario and McMaster Universities Osteoarthritis Index | 24-item measure assessing lower extremity pain, stiffness and function. All items are measured on a 5-point Likert scale (0-4; total score 0-96), with higher scores indicating worse symptoms. | Baseline to 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| 30-second chair stand test | Participants are asked to rise and sit back down in a chair as many times as they can during 30 seconds, without using hands or arms for support. Higher numbers of chair stands indicate better function. | Baseline to 6 months |
| 2 minute march test |

Participants are asked to march in place, taking as many "steps" as they can within 2 minutes, bringing the knees to approximately a 90-degree angle. If the patient is not bringing knees to an appropriate height, the study team member administering the test will ask them to raise their knees higher; if proper knee height cannot be maintained, the patient may continue the test, but this is noted on the score sheet. Higher numbers of steps indicate better function. |
