Trial Outcomes & Findings for Delaware Physical Exercise and Activity for Knee Osteoarthritis (NCT NCT04980300)

NCT ID: NCT04980300

Last Updated: 2025-01-01

Results Overview

Actigraph GT3X monitor to be worn over the right hip during waking hours. Participants will be instructed to wear the monitor for 7 consecutive days, and then return the monitor via mail in a pre-addressed, pre-stamped envelope that is provided. Units are in minutes/day of Moderate to vigorous intensity physical activity (MVPA), min 0, max 1440, with higher scores representing more time in MVPA

Measure
Expanded Intervention
Virtual consultation sessions with a physical therapist, focusing on lower extremity strengthening exercises, physical activity (i.e., walking), and education about knee osteoarthritis. Expanded Intervention: Participants in the Expanded Intervention arm will receive five virtual consultation sessions, delivered by a physical therapist over 12 weeks (at Weeks 1, 2, 4, 7, and 10) and lasting approximately 45-60 minutes each. Each session will focus on lower extremity strengthening exercises, physical activity (i.e., walking), and education about knee osteoarthritis. Participants will be provided with an exercise manual, tracking log, educational manual, and a step counter. Participants will be prescribed up to 6 exercises (quadriceps, hip abductor/gluteal, hamstrings/gluteal, calf, balance) and daily walking step goals. Progression will be a joint decision by the participant and physical therapist. Education will include information on knee osteoarthritis, managing pain, being active, weight loss, dealing with setbacks, and progressing activity. The physical therapist will also discuss barriers and facilitators to meeting and progressing goals as appropriate.
Brief Intervention
Web-based resources on knee osteoarthritis, including an overview of knee osteoarthritis, brief anatomy of the knee and how that is related to pain, different types of arthritis pain and how to manage it, and how to be active with arthritis. Brief Intervention: Participants in the Brief Intervention arm will receive access to a study-specific website that navigates them to a variety of web-based resources on knee osteoarthritis. Topics for the various resources include an overview of knee osteoarthritis, brief anatomy of the knee and how that is related to pain, different types of arthritis pain and how to manage it, and how to be active with arthritis. Sessions range from 20 - 70+ minutes.

PRIMARY outcome

Timeframe: Baseline to 12 weeks as primary outcome Baseline to 24 weeks as secondary outcome

Population: For activity monitor data, we used a modified intention-to-treat method, i.e., all randomly assigned participants who wore the monitor for \> 4 days for at least 10 hours/day at baseline were included in analyses. There were 15 (14.6%) study participants who were randomized, but did not have valid baseline activity monitor data despite wearing the monitor and were excluded from the primary analysis. Thus, the modified intention-to-treat sample included n=88.

Population: We analyzed our intention to treat (ITT) sample, which included all subjects who were randomized.

Participants will be asked to complete the treatment Beliefs of OA (TOA) Physical Therapy measure, which is a 9-item questionnaire that assesses health beliefs (positive and negative) related to physical therapy. Scores of the TOA PT Positive are on a scale of 7 to 28 with higher scores mean better outcome, i.e., more positive treatment beliefs

OTHER_PRE_SPECIFIED outcome

Timeframe: Baseline, 12 weeks, and 24 weeks

Population: We analyzed our intention to treat sample, which included all subjects who were randomized.

Change in knee pain will be measured using a single-item Visual Analog Scale (VAS) question in which the participant will indicate their pain in each knee. Scores range from 0-100 where 0 is no pain and 100 is the worst pain imaginable. An index knee to be used for analysis is defined as the knee with worse pain at baseline. Scores of the Knee pain Visual Analogue Scale are on a scale of 0 to 100 with higher scores mean worse outcome, i.e., more pain

The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a 42-item questionnaire that assesses five domains, including pain, symptoms (other than pain), function in activities of daily living, function in sport and recreation, and quality of life. The KOOS has subscale scores for Pain, Symptoms, ADL Function, Sport \& Recreation Function, and Quality of Life. Scores are transformed to a 0-100 scale with 0 indicating extreme knee problems and 100 indicating no knee problems. KOOS Pain, min 0, max 100, with higher scores representing a better outcome

Intervention
n=45 Participants
Virtual consultation sessions with a physical therapist, focusing on lower extremity strengthening exercises, physical activity (i.e., walking), and education about knee osteoarthritis. Intervention: Participants in the Intervention arm will receive five virtual consultation sessions, delivered by a physical therapist over 12 weeks (at Weeks 1, 2, 4, 7, and 10) and lasting approximately 45-60 minutes each. Each session will focus on lower extremity strengthening exercises, physical activity (i.e., walking), and education about knee osteoarthritis. Participants will be provided with an exercise manual, tracking log, educational manual, and a step counter. Participants will be prescribed up to 6 exercises (quadriceps, hip abductor/gluteal, hamstrings/gluteal, calf, balance) and daily walking step goals. Progression will be a joint decision by the participant and physical therapist. Education will include information on knee osteoarthritis, managing pain, being active, weight loss, dealing with setbacks, and progressing activity. The physical therapist will also discuss barriers and facilitators to meeting and progressing goals as appropriate.
Control
n=51 Participants
Web-based resources on knee osteoarthritis, including an overview of knee osteoarthritis, brief anatomy of the knee and how that is related to pain, different types of arthritis pain and how to manage it, and how to be active with arthritis. Control: Participants in the Control arm will receive access to a study-specific website that navigates them to a variety of web-based resources on knee osteoarthritis. Topics for the various resources include an overview of knee osteoarthritis, brief anatomy of the knee and how that is related to pain, different types of arthritis pain and how to manage it, and how to be active with arthritis. Sessions range from 20 - 70+ minutes.

Timeframe: Baseline and after randomization

The participant will complete a Treatment Expectations Question, which asks the participant how effective they expect the intervention to be for their knee. This question will be collected at the baseline timepoint: right before and right after randomization. Answers will be expressed as frequencies and percentages for each of the following categories: No effect at all, Minimal improvement, Moderate improvement, Large improvement, and Complete recovery, as well as reported as an increase, decrease, or no change in treatment expectations. Score ranges from 1 to 5 with higher scores representing higher expectations of improvement following treatment.
