Clinical Trial 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.

Related Conditions & MeSH terms

• Knee Osteoarthritis
• Osteoarthritis
• Osteoarthritis, Knee

Intervention

Other:
• Blood 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.
• Anti-gravity treadmill
The intervention will be applied walking/running on the anti-gravity treadmill.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Post-operative knee outcome on Western Ontario and McMaster Universities Arthritis Index	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.
