Anti-Gravity Treadmill Training for Knee Osteoarthritis

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective randomized trial compares conventional physiotherapy alone to conventional physiotherapy plus gait re-education using an anti-gravity treadmill in adults with knee osteoarthritis. Participants, aged 40–70 with radiographically confirmed KL grade 2–3 and chronic knee pain, will be randomized to 4 weeks of therapy, 3 sessions per week. Outcomes include gait parameters, range of motion, knee function, quality of life, and body composition. The study aims to determine if the R-Force body-weight-supported treadmill offers added benefits over standard care.

Why it matters

Who can join: the full rules

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.
