What is the purpose of this trial?

This trial explores a new exercise method using a hip flexion feedback system (HFFS) for individuals with obesity and osteoarthritis. The goal is to determine if this system can improve fitness, reduce pain, and enhance mobility. Participants will either use the HFFS in a 12-week exercise program or wait 12 weeks before starting the same program. The trial seeks individuals with knee osteoarthritis, a body mass index (BMI) of 30 or higher, and a sedentary lifestyle. As a Phase 1 and Phase 2 trial, this research aims to understand how the treatment works in people and measure its effectiveness in an initial, smaller group.

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 is best to discuss this with the study coordinators or your doctor.

What prior data suggests that the Hip Flexion Feedback System is safe for people with osteoarthritis and obesity?

Research has shown that a Hip Flexion Feedback System (HFFS) might provide a safe exercise option for individuals with osteoarthritis and obesity. A review of 37 studies involving 1,235 participants found that exercises focusing on the knees and hips, combined with feedback systems like the HFFS, can help reduce knee pain. This indicates that most people can use the HFFS without major side effects.

The trial remains in its early stages, and researchers continue to gather safety information. However, the trial's progression to this stage suggests that earlier research found the HFFS safe for participants. The system is designed to offer a more controlled and safer exercise method, potentially resulting in fewer injuries or problems compared to traditional exercises like running or cycling. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Exercise Monitoring System for Osteoarthritis because it introduces a novel way of managing osteoarthritis symptoms through real-time feedback during exercise. Unlike traditional treatments like medications, physical therapy, or surgery, this system uses a Hip Flexion Feedback System (HFFS) to guide high-intensity exercise by providing visual cues on a TV screen, helping participants adjust knee lift and foot impact based on their heart rate. This approach not only personalizes the exercise regimen but also aims to enhance muscle strength and joint function more effectively and safely. By potentially improving exercise outcomes, this method could offer a non-invasive alternative to managing osteoarthritis, which is a significant advancement over existing options.

What evidence suggests that the Hip Flexion Feedback System is effective for osteoarthritis?

Research has shown that a Hip Flexion Feedback System (HFFS) could be a beneficial exercise tool for individuals with osteoarthritis and obesity. Early results suggest that this system, which controls knee movement and foot impact during treadmill walking, may enhance fitness and reduce joint pain. In this trial, participants in the intervention group will use the HFFS during a 12-week high-intensity exercise program. A similar study with patients experiencing hip problems demonstrated significant improvements in hip function after using exercise monitoring systems. This suggests that the HFFS might enhance movement and alleviate pain in those with osteoarthritis. The system aims to make exercise safer and more effective by adjusting intensity based on heart rate. Overall, early indications show potential benefits for pain relief and improved movement. ^{1 2 3 4 6}

What Are the Treatments Tested in This Trial?

Interventions

• Hip Flexion Feedback System (HFFS)

Trial Overview

The study tests a hip flexion feedback system (HFFS) that guides knee-lifting exercises on a treadmill based on real-time heart rate to improve fitness and reduce pain in people with osteoarthritis and obesity compared to those not exercising.

How Is the Trial Designed?

Group I: Intervention Experimental Treatment 1 Intervention

This group will do a 12-week high intensity exercise program. The subjects will exercise by increasing how much they lift their knees while walking on treadmill. The exercise will also involve controlling the impact of the feet on the treadmill. A TV placed in front of the treadmill shows how high individuals need to lift their knees. How much participants need to lift their knees is calculated based on real-time heart rate readings.

Group II: Control Active Control 1 Intervention

This group will do initially a 12-week period of no intervention. After these 12 weeks, participants will do a 12-week high intensity exercise program. The subjects will exercise by increasing how much they lift their knees while walking on treadmill. The exercise will also involve controlling the impact of the feet on the treadmill. A TV placed in front of the treadmill shows how high individuals need to lift their knees. How much participants need to lift their knees is calculated based on real-time heart rate readings.

The study analyzed the kinematics of the overhead deep squat (OHDS) in 45 healthy adults and found that higher FMS scores (specifically a score of 3) were associated with greater peak hip flexion, knee flexion, and ankle dorsiflexion angles, indicating better squat depth.

However, no significant differences were observed between individuals scoring 2 and 1, suggesting that the FMS scoring may not effectively differentiate kinematic risks for lower extremity injuries, particularly in frontal and transverse plane movements.
