Define Physiotherapy is home to the revolutionary AlterG® Anti Gravity Treadmill™

The AlterG® Anti-Gravity Treadmill™ integrates patented, NASA Differential Air Pressure (DAP) technology, a precise air calibration system, and real-time information to change what’s possible in rehabilitation and training. Using a pressurised air chamber to uniformly reduce gravitational load and body weight in precise 1% increments, AlterG enables patients and athletes to move unrestricted and pain-free – restoring and building muscle strength, range of motion, balance, function, and fitness. No other unweighting technology offers as much freedom, control, and versatility.

Using air to unweight patients and athletes enables an unprecedented level of comfort and mobility – without impeding natural gait mechanics.  

NASA-based technology applies positive air pressure to gently unweight users in 1% increments to as low as 20% of their body weight – quickly, effortlessly, and precisely.

We can help you to calibrate your effective body weight based on your comfort level to achieve pain-free movement or to allow for partial weight bearing exercise as tolerated.

The positive air pressure chamber and fall-safe environment enable the controlled progression of weight-bearing activity and training volume – without impact on joints or risk of injury.

The Define AlterG Difference

• Innovative technology supports your normal walking and running biomechanics – unlike conventional alternatives such as hydrotherapy.  

• The AlterG eliminates your hydrotherapy infection risk allowing early and pain-free mobilisation. 

• Real-time gait data and live video monitoring help you with immediate visual feedback to improve your experience and results.

• Fall-safe environment gives you the confidence to move like never before.

• Encourages your range of motion, shown to improve outcomes.

• Walk, run, and perform exercises that help you recover, maintain, and enhance your balance, strength, and mobility

Injuries that respond well to training on the AlterG include:

• Shin splints/lower limb bone stress injuries (NOT fractures until healing is sufficient)

• Ankle sprains

• Knee and patella injuries

• Post-surgery - ankles, knees and hips

• Muscle tears - calf, quads, glutes

• Low back injury or soreness

The AlterG enables uninjured athletes to increase training load more safely.
