ClinConnect Summary

This clinical trial is exploring a new exercise method for people with knee osteoarthritis (OA) and obesity. The study uses a special system called the hip flexion feedback system (HFFS), which helps participants exercise by encouraging them to lift their knees higher while walking on a treadmill. This method aims to reduce pain and improve fitness without the high impact that traditional exercises like running can cause. Participants will be divided into two groups: one will use the HFFS for a 12-week exercise program, while the other will not exercise. The goal is to see how this new approach affects their fitness, pain levels, and mobility.

To be eligible for the trial, participants must be between 30 to 75 years old, have a body mass index (BMI) of 30 or higher, and have knee OA symptoms. They should also be relatively inactive, meaning they don't exercise regularly. Participants can expect to engage in a structured exercise program while having their heart rate monitored to ensure they are exercising at the right intensity. This study could lead to safer and more effective exercise options for people with osteoarthritis and obesity, and it may also help develop home-based exercise programs in the future.
