Exercise Programs for Knee Pain
(SMARTSTEP Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to evaluate the effectiveness of two exercise programs for knee pain related to intermittent claudication, a condition causing leg pain due to poor blood flow. One group will use a smartphone app for guidance (smartphone-enabled structured exercise therapy, or SE-SET), while the other will follow exercises prescribed by their doctor (standard exercise therapy). The goal is to determine which method more effectively alleviates knee pain. Suitable participants have stable leg pain from poor circulation, can walk, but experience pain during exercise. As an unphased trial, this study offers participants the chance to contribute to valuable research that could enhance exercise therapies for knee pain.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.
What prior data suggests that these exercise programs are safe for knee pain?
Research has shown that using apps for exercise, such as smartphone-enabled structured exercise therapy (SE-SET), is safe for people with knee osteoarthritis. Studies have found that mobile apps for exercise typically do not cause serious side effects. Instead, they help manage symptoms and encourage healthy habits.
One study found app-based programs to be safe and effective, offering an easy way for patients to engage in physical therapy. These digital tools help patients adhere to their exercise routines and achieve better results. Users often report positive experiences, noting the apps' convenience and ease of use.
Overall, evidence suggests that SE-SET is well-tolerated and poses little risk to participants, making it a promising option for managing knee pain through guided exercise.12345Why are researchers excited about this trial?
Researchers are excited about these treatments for knee pain because the smartphone-enabled structured exercise therapy (SE-SET) offers a fresh approach to managing the condition. Unlike standard exercise therapies that rely heavily on self-direction, SE-SET integrates technology to enhance patient engagement and adherence. It includes daily exercise reminders, a virtual diary for tracking progress, secure messaging with a health coach, and educational videos, making it more interactive and personalized. These features aim to improve outcomes and provide patients with a more comprehensive support system for their rehabilitation journey.
What evidence suggests that this trial's exercise programs could be effective for knee pain?
This trial will compare two exercise programs for knee pain: Smartphone-enabled structured exercise therapy (SE-SET) and Standard exercise therapy. Research has shown that smartphone-based exercise programs, like SE-SET, can reduce knee pain and improve knee function. In studies, participants using online exercise programs reported less pain and better mobility after six weeks compared to those receiving regular care. Another study found that telehealth exercises helped individuals with knee osteoarthritis experience less pain and improved daily function. These findings suggest that smartphone apps can effectively manage knee pain.56789

Are You a Good Fit for This Trial?
This trial is for adults aged 18-89 with Peripheral Arterial Disease (PAD), who can consent and have specific Ankle-Brachial Index (ABI) or Toe-Brachial Index (TBI) scores indicating reduced blood flow. It's not for those whose walking is limited by other conditions, have life-threatening illnesses, severe heart failure, active behavioral issues that affect participation, or cannot attend study visits.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants engage in a 12-week exercise program using either a smartphone-enabled app or standard physician-directed exercise therapy
Follow-up
Participants are monitored for changes in exercise capacity and cardiovascular outcomes
What Are the Treatments Tested in This Trial?
Interventions
- Smartphone-enabled structured exercise therapy (SE-SET)
- Standard exercise therapy
Trial Overview
The trial compares a smartphone-enabled structured exercise therapy program with coaching to the usual physician-directed exercise therapy. The goal is to see if using smartphones for guided exercises helps people with PAD better than standard advice from their doctors.

Treatment groups
Experimental Treatment
Active Control
This arm involves a smartphone app Movn - rehabilitation platform based on MULTIFIT, a case-management system for secondary prevention and patient surveillance after acute MI. The key features of the smartphone app include daily reminders to exercise, virtual diary for patients to enter data on exercise sessions, two-way secure messaging with the health coach, and educational videos on heart and vascular health.
Self-directed, unsupervised exercise as prescribed by the patient's physician.
