What is the Alter G Treadmill?

The Alter G or anti-gravity treadmill is a revolutionary piece of medical rehabilitation equipment which allows “unweighting” of the body between 20 – 100% using an air pressure system developed by NASA. The unique capability means that normal gait pattern can be maintained safely, accurately and comfortably even whilst recovering from injury to the lower part of the body. This leads to a quicker recovery with less pain.

Who Would Benefit from Using the Alter G?

In a word: everyone. In conjunction with your physiotherapist, athletes and the general population use the Alter G to gain strength and conditioning whilst reducing the impact on the joints. People post-injury or post-operatively use the machine to begin a safe rehab to areas in the lower body, spine, hip, knee, ankle & foot often much sooner by using the unique loading facility.

Sporting Performance and Training

  • Train safely for endurance events
  • Use to recover from a long race
  • Increase load gradually to increase intensity of training
  • Develop cardio-vascular fitness without lower body injury
  • Prolong your running career without the pounding impact


  • After an injury, the Alter G allows quick return for runners to activity/training, overcoming those months without logging any km’s
  • Post surgery. A large number of spinal & lower limb surgeries require patients up & walking normally asap. Alter G provides a pain free way to do this
  • Stroke patients can exercise in a completely safe way as all movements are supported
  • Also for those who suffer from balance & neurological problems the Alter G is enclosed

The Elderly and Overweight

  • Alter G provides a safe enclosed option for those fearful of walking on the footpath or uneven surfaces
  • The load bearing ability provides for a gradual increase in intensity particularly useful for those overweight

Who Uses the Alter G Treadmill?

Teams from Australia and all around the world make the AlterG a central part of their training and conditioning, including:

  • NRL teams: Most NRL teams including this year’s premiers: Cronulla-Sutherland Sharks,
  • AFL teams: All AFL teams including Western Bulldogs, Sydney Swans and GWS Giants
  • Australian Institute of Sport
  • Most of the NBA teams, including the world champion Miami Heat
  • All of the English Premier League soccer clubs, including Manchester City
  • US Olympic Training Centres


The FMS (which stands for Functional Movement Screen) is an injury prevention tool used to identify limitations or asymmetries in your fundamental movement patterns.

These tests are key to identifying functional movement quality in people with no current pain complaint or known musculoskeletal injury. The FMS is a reliable and well-researched tool that works in the same way that a blood pressure reading might flag a cardiovascular issue before symptoms become apparent.

The FMS allows us to observe you performing basic movements by placing you in challenging positions where weaknesses and imbalances become noticeable. The results of your FMS then help us to communicate properly with you and your coach/trainer in discussing the safest and most effective ways for you to exercise.

The total appointment lasts for 45 minutes, during which time your screen is completed and an exercise program is tailored to correct any movement limitations found during the screen. If your screen identifies significant problems, like pain or gross limitations in movement, we’ll discuss further consultation that may be required to appropriately deal with those problems.

We have practitioners at both Castlereagh Street and Macquarie Street clinics who are certified in administering the screen.

During your session, you should wear exercise clothes and don’t worry, there’s no sweat involved!
