MyTherEx: Mobile Technology to Support Physical Therapist Directed Exercise for People Aging With Arthritis

Osteoarthritis is the leading cause of disability in the U.S, particularly in older adults. Exercise is an evidence-based treatment option that improves pain and disability outcomes in adults with osteoarthritis, but adherence to prescribed exercise is generally low. Technology such as mobile applications (apps) for smartphones and tablets offers the potential to support exercise adherence through evidence-based components and enhanced communication between physical therapists and patients. The investigators aim to test mobile app-supported physical therapy exercise prescription compared to standard care. The investigators propose to use a two-arm randomized control trial with subjects in the intervention receiving mobile app-supported physical therapy exercise prescription and the control group receiving usual care physical therapy exercise prescription (paper handouts and verbal instruction). No known studies have assessed the impact of technological integration on adherence with PT exercises for OA. Current approaches such as therapist drawn pictures, hand-written or print-ready instructions do not account for patient communication preferences or ability to translate drawings into physical action. Mobile technology offers a potential solution to patient-centered care but has not been evaluated. This study will provide valuable information on effectiveness and user perspectives to key stakeholders such as patients, health care administrators, physical therapists and app designers.

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Osteoarthritis (OA) is the leading cause of disability in the U.S. The rate of activity limitation due to OA is progressing faster than expected while prevalence is projected to increase as a result of the obesity epidemic and population aging, making it a major public health problem. Exercise is an evidence-based treatment option that improves pain and disability outcomes in adults with osteoarthritis, but previous research has shown that adherence to prescribed exercise is low. Referral to physical therapy is common for people with OA with the standard of care including exercise prescription through paper handouts with brief instruction and static pictures. Such approaches do not incorporate known determinants of behavior change related to exercise adherence.

Recent technology products such as mobile applications (apps) for phones and tablets offer the potential to enhance communication between physical therapists and patients. The investigators aim to test a pragmatic intervention focused on supporting people with osteoarthritis to remain engaged with an exercise program. The specific aims of the project are to:

  1. Compare the effectiveness of mobile app supported exercise prescription to usual care (paper exercise prescription) on exercise adherence among mid-life and older adults receiving similarly dosed physical therapy for lower extremity OA. The investigators will also examine secondary outcomes of exercise self-efficacy, physical function, stiffness, and pain.
  2. Examine the feasibility and acceptability of mobile app supported exercise prescription through recruitment and retention rates, satisfaction with care ratings, and qualitative feedback.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Mobile Application Group
The mobile app group will receive physical therapy as determined by the physical therapist and agree to receive the home exercise prescription using a mobile app on their phone or personal tablet
Device: Mobile Application
Participants will receive usual care physical therapy guided by Clinical Practice Guidelines and based on individual symptoms and need over 7 in-person visits. Measures will be collected by the physical therapist related to leg strength, balance, fitness, and mobility as part of the usual care physical therapy evaluation and follow-up. The treating physical therapist will negotiate the physical therapy intervention based on patient preferences and goals and assessment findings. Using clinical practice guidelines, the intervention for the research participants is expected to address deficits in strength, mobility, balance, and cardiovascular endurance. Exercise prescription will be provided using the Wellpepper physical therapy exercise prescription mobile app.
No Intervention: Control
The control group will receive physical therapy as determined by the physical therapist based on clinical practice guidelines and will receive the home exercise program in the traditional way through paper exercise handouts
