Floating on air: anti-gravity treadmill tested for hip replacement recovery
NCT ID NCT07170215
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether walking on an anti-gravity treadmill (which reduces body weight by 80%) helps people recover strength and mobility after total hip replacement. 34 adults with hip osteoarthritis were randomly assigned to either anti-gravity treadmill training or standard physiotherapy. The main focus was on hip muscle strength, along with pain and walking tests.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- anti-gravity treadmill (ALTERG VIA device)
- What this could lead to
- If it works, this could offer a gentler way to exercise early after hip replacement, possibly speeding up recovery of strength and mobility.
- What could go wrong
- This is a small, single-center trial with only 34 people. The results may not apply to everyone, and the device is not a substitute for standard rehab.
