Alter-G Training/Rehab

Anti Gravity Rehabilitation


Fantastic to have the Alter-G Anti-Gravity treadmill available at our rehabilitation clinic in Hamilton, South Lanarkshire.

If you are recovering from lower-limb, spinal surgery or any neurological condition such as stroke, then our main rehabilitation clinic is the perfect place for you to start your recovery.


Originally conceived by Dr Robert Whalen to design effective exercise regimens for NASA’s astronauts, Differential Air Pressure (DAP) technology has been adapted by AlterG for use in training and rehabilitation. The AlterG Anti-Gravity Treadmill is a medical device that can be used for:

  • Rehabilitation of lower extremity injuries
  • Treatment of neurological conditions
  • Weight reduction
  • Aerobic conditioning
  • General training to combat the diseases of aging

Unweighting is achieved in the AlterG by using air in a pressure-controlled chamber to gently lift the user.

Precise calibration using our patented technology allows for very specific unweighting from 100-20% of the user’s body weight in 1% increments.

Something no other unweighting modality can do.

  • Literature Review
  • The Science of Unloading and Progressive Loading – The beneficial effects of controlled mobilization and loading on healing tissue are well documented in the scientific literature. Similarly, the detrimental effects of prolonged under-loading and immobilization are also well known. In the following review, selected clinical topics are discussed which provide the foundation behind the theory of unloading and progressive loading used in rehabilitation and training with the AlterG Anti-Gravity Treadmill.

Clinical studies show that the AlterG can help decrease ground reaction forces in walking and running.

The restoration of normal gait mechanics is paramount to optimal recovery and can be accelerated by the unweighting technology.

Why Unload?

  • Allow for the protection of healing tissue
  • Encourage range of motion
  • Earlier initiation of closed-kinetic chain activity.
  • Prevent disuse atrophy
  • Encourages more rapid return of motor control
