Knee osteoarthritis rehab, Five Dock
Walk and run with significantly less pressure through the knee joint. The anti-gravity treadmill improves movement tolerance, strength and confidence — progressively and without pain.

Why the anti-gravity treadmill
Knee osteoarthritis cannot be reversed — but the research is clear that progressive exercise and movement improve pain, function and quality of life more than most other interventions. The challenge for many patients is that walking and running on the ground is painful, which creates a cycle of avoidance and deconditioning that makes things worse.
The anti-gravity treadmill breaks this cycle. By reducing body weight by 40–60%, the compressive forces through the arthritic knee joint are dramatically reduced — often below the pain threshold — allowing movement to occur comfortably. Over time, as tolerance builds, the support is gradually reduced and the knee learns to handle more load.
The goal is not to eliminate pain completely — it's to expose the joint to progressively more load in a controlled way, improving the strength and capacity of the surrounding muscles that support the knee. This is the most effective long-term management strategy for knee OA.
The protocol
Four phases from supported walking through progressive exposure and ongoing management.
Supported walking
- 40–60% body-weight support
- Comfortable walking pace for 15–20 minutes
- Focus on smooth, controlled movement
- Monitor gait symmetry and comfort
Progressive exposure
- 20–40% body-weight support
- Transition from brisk walking to slow jogging where appropriate
- Gradually increase duration before reducing support
- Monitor next-day swelling and stiffness
Load tolerance build
- Reduce support gradually as tolerated
- Increase speed or gentle incline if guided by physio
- Improve confidence with normal movement patterns
- Increase duration and speed gradually
Ongoing management
- Supported sessions may be used long-term
- Alternate treadmill and outdoor activity
- Manage flare-ups by adjusting support level
- Maintain cardiovascular fitness throughout
Progression & red flags
These rules guide progression through the protocol and flag when to regress.
When to progress
- Increasing tolerance to load — not eliminating symptoms completely
- Reduce body-weight support slowly over weeks
- Gait symmetry maintained
- Comfort improving with duration
When to regress
- Increased swelling or stiffness next day
- Antalgic gait develops or worsens
- Pain significantly worsens during sessions
- Confidence with movement declines
Ongoing use
- Supported sessions can be used indefinitely for symptom management
- Particularly useful during flare-up periods
- Complements a land-based strengthening program
