Beskrivelse
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.

Eksperimentel: Experimental Group
Patients in this group will receive a comprehensive 4-week therapeutic program, 3 times a week.
The intervention combines conventional physiotherapy with gait re-education and training on the R-Force bodyweight- supported anti-gravity treadmill.
Each therapy session will last approximately 90 minutes.
|
A standard program consisting of targeted physical exercises, range of motion improvements, and strength conditioning for patients with knee osteoarthritis.
Traditional physiotherapy will include isometric exercises, strengthening, stretching, balance exercises (with elements of proprioception training), active non-weight-bearing exercises, functional exercises, gait exercises, as well as breathing and relaxation exercises.
Gait re-education and body-weight-supported treadmill training using the R-Force anti-gravity treadmill to reduce joint loading during exercise.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Knee Injury and Osteoarthritis Outcome Score (KOOS)
Tidsramme: Baseline (before intervention), 4 weeks (immediately post-intervention), and 8 weeks (follow-up)
|
Change from baseline in knee joint function and symptoms using the KOOS questionnaire.
The questionnaire assesses 5 subscales: Pain, Symptoms, Activities of Daily Living, Sport and Recreation Function, and Knee-related Quality of Life.
Scores range from 0 to 100, where 100 indicates no symptoms and 0 indicates extreme symptoms.

|
Gait Parameters - Stride Length
Tidsramme: Baseline (before intervention), 4 weeks (immediately post-intervention), and 8 weeks (follow-up)
|
Change from baseline in mean stride length (measured in centimeters) during treadmill walking, evaluated using the built-in spatio-temporal analysis system of the R-Force treadmill.

|
Change from baseline in the maximum distance (measured in meters) that a participant can walk quickly on a flat, hard surface in a period of 6 minutes.
|
Baseline (before intervention), 4 weeks (immediately post-intervention), and 8 weeks (follow-up)
