Development of Camera Based Gait Quality Measure for Persons With Multiple Sclerosis

This study is developing a simple camera-based system that can measure walking quality in people with multiple sclerosis (MS). Using a regular video camera, the system analyzes how a person walks to detect gait problems that might indicate disease progression — potentially providing a cost-effective monitoring tool outside of specialist clinics. **You may be eligible if...** - You have a relapsing form of MS (including relapsing-remitting MS or secondary progressive MS) - You can walk independently - You have not had a relapse (flare-up) in the past month - You are 18–75 years old - If you take dalfampridine (a walking aid medication), your dose has been stable for at least 2 months **You may NOT be eligible if...** - You have had an orthopedic injury, fracture, or surgery that affects your ability to walk or bear weight normally Talk to your doctor to see if this trial is right for you.
