Could an Anti-Gravity treadmill make knee arthritis physiotherapy work better?
NCT ID NCT07813078
First seen Sep 10, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
Researchers are testing whether adding gait re-education on an R-Force anti-gravity treadmill to standard physiotherapy helps adults with knee osteoarthritis. The trial enrolls 80 people aged 40 to 70 who have radiologically confirmed knee arthritis and ongoing knee pain. Participants are randomly assigned to either standard physiotherapy alone or standard physiotherapy plus treadmill training three times a week for four weeks. The team measures walking patterns, knee function, pain, and quality of life before the program, right after it, and eight weeks later.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- gait re-education on an R-Force anti-gravity treadmill added to standard physiotherapy
- What this could lead to
- If it helps, this could give physiotherapists a way to add supported walking practice to standard knee osteoarthritis care, possibly improving gait and function more than exercise alone.
- What could go wrong
- The trial is small, with 80 participants, and a 4-week program may not produce lasting changes. Any added benefit could fade after the supervised sessions end, and treadmill training may not suit everyone with knee pain.

Inclusion Criteria: * Radiologically confirmed knee osteoarthritis (grade 2 or 3 according to the Kellgren-Lawrence classification). * General health and functional status allowing participation in the physical therapy program (based on clinical assessment). * Knee joint pain persisting for at least 3 months, with an intensity of \>= 4 on the Visual Analog Scale (VAS). * Age between 40 and 70 years. * Ability to ambulate independently without any orthopedic assistive devices. * Voluntary written informed consent to participate in the study. * No medical contraindications to physical exercise. Exclusion Criteria: * Knee osteoarthritis grade 4 according to the Kellgren-Lawrence classification or lack of radiological changes (grade 0-1). * History of total or partial knee arthroplasty (joint replacement). * Contraindications to body composition analysis (e.g., implanted pacemaker, electronic implants, epilepsy). * Knee joint instability (e.g., ligamentous injury). * Acute joint inflammation. * Neuropathies, myopathies, or other neurological conditions affecting gait. * Active neoplastic diseases (cancer) or advanced cardiovascular diseases. * Participation in other clinical trials within the last 6 months. * Participation in another physical therapy or rehabilitation program within the last 6 months. * Planned intra-articular injections or injections received in the affected knee joint within the last 3 months. * Regular use of analgesic or anti-inflammatory drugs (NSAIDs, corticosteroids) at doses that could affect the assessment of pain and function.
