AlterG in the Sydney CBD | 4DHP

The clinical significance of the Alter G Anti-Gravity Treadmill is enabled by manipulating differential air pressure; creating a pressurised lifting force to decrease the impact of gravitational forces and body weight during locomotion. As a result, ground reaction forces are minimised and the associated muscles work at a safer, less strenuous level to attenuate forces. Alongside smaller ground reaction forces, the gravitational load can be reduced from 100% to as low as 20% of body weight, allowing us to target biomechanical insufficiencies and maintain cardiovascular fitness without overloading the patient specific site of injury. As such, the Anti-Gravity Treadmill appeals to any individual whose lower extremity symptoms are related to full weight bearing during ambulation or exercise.

Benefits of the AlterG Anti-Gravity Treadmill

The Alter G Anti-Gravity Treadmill proves to be a clinically significant tool in managing a variety of populations through decreasing physiological strain and heightening safety. With this technology, both the evidence-based research and our clinical experience have demonstrated it to be monumental in an individual’s recovery and maintenance of their condition/injury.


As it offers an alternative for weight-bearing exercise, orthopaedic patients see significantly reduced pain without compromising joint integrity, favouring osteoarthritis. Additionally, this reduced joint loading allows the incorporation of the treadmill into postoperative protocols to reach full weight bearing.


Similarly, gait training using the Anti-Gravity treadmill appeals to the majority of neurological pathologies, improving the motor learning of kinematics that favour functional improvements; seen especially in Parkinson’s Disease, Cerebral Palsy, Cerebrovascular Accidents, and Traumatic Brain Injury.


There is no significant change in heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure associated with cardiac patients; allowing deconditioned clients with lower body pain to participate in treadmill exercise and stress testing.


This heightened safety allows us to target gait kinematics and walking speed in geriatric patients, ultimately improving their balance and functional capacity in activities of daily living.


This technology is significant in managing sports/performance training. By reducing the metabolic demand for the athlete, we can manipulate the cardiovascular and weight-bearing load in training blocks to prepare for future events. Additionally, an athlete post-injury would benefit from reduced joint and muscle loading with the goal of returning to athletic performance.
