Knee Osteoarthritis
Conditions
Brief summary
The aim of this randomized controlled study is to investigate whether the implementation of Blood Flow Restriction, in which the de-loading factor is delivered by the combined progressive de-loaded walking to running activity on an antigravity treadmill (treatment group), is more effective than the same antigravity protocol alone (control group). Participants will be divided as follows: Intervention group: anti-gravity treadmill combined with blood flow restriction Control group: anti-gravity treadmill Both groups will also undergo a standardized knee Osteoarthritis management through an aerobic and strength program.
Interventions
OTHERBlood flow restriction training + Anti-gravity treadmill
Blood flow restriction training is administered via straps applied to the proximal limb with the possibility to adjust the applied occlusion pressure in order to prevent venous return leaving the arterial flow partially free. The consequent blood pooling causes a reduction in tissue saturation with oxidative stress and an increased growth factors secretion. The intervention will be applied while walking/running on the anti-gravity treadmill.
The intervention will be applied walking/running on the anti-gravity treadmill.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Post-operative knee outcome on Western Ontario and McMaster Universities Arthritis Index | Change from Baseline to 6 months | Questionnaire at baseline (day 1) and 6 weeks, and at 3, 6 months. The WOMAC questionnaire is composed of 3 sub-scores that evaluate pain (5 questions, 0-20 points), stiffness (2 questions, 0-8 points), and function (17 questions, 0-68 points) and is a validated patient-reported outcome measure (PROM) to evaluate knee osteoarthritis. |
