At Total Physical Therapy, we are committed to providing cutting-edge rehabilitation solutions that help our patients recover faster and regain their mobility safely. One of the most advanced technologies we offer is the Alter G Weightless Walking Machine, an innovative tool designed to make movement easier and more effective for patients recovering from injuries, surgeries, or chronic conditions.
What is the Alter G Weightless Walking Machine?
The Alter G Weightless Walking Machine is a revolutionary anti-gravity treadmill that uses NASA-developed Differential Air Pressure (DAP) technology to reduce the weight-bearing load on the body. Unlike traditional treadmills, the Alter G allows patients to walk or run at a fraction of their body weight, minimizing impact while still allowing for functional movement.
By gradually reducing the amount of weight the lower body has to support, patients can retrain muscles, improve range of motion, and rebuild strength with significantly less stress on their joints. This enables safe, effective movement for those recovering from injury, surgery, or mobility issues.

Who Benefits from Alter G Therapy?
The Alter G is a game-changer for many different types of patients. Those who may benefit the most include:
- Post-Surgical Patients
Recovering from knee, hip, or ankle surgery can be challenging due to pain, swelling, and limited mobility. The Alter G allows patients to gradually ease into weight-bearing movements, reducing the risk of complications while improving circulation and muscle activation. - Athletes Rehabbing from Injury
For athletes recovering from ACL tears, stress fractures, or muscle strains, staying active during recovery is crucial. The Alter G helps maintain cardiovascular endurance and muscle strength while minimizing impact on healing tissues. By using this technology, athletes can return to their sport stronger and faster without the fear of re-injury. - Seniors with Mobility Challenges
Aging often brings joint pain, balance issues, and reduced mobility. The Alter G provides a safe, controlled environment for seniors to improve walking mechanics, strength, and endurance without putting excessive strain on their joints. It’s an ideal tool for fall prevention and overall functional mobility. - Patients with Neurological Conditions
Individuals with conditions such as Parkinson’s disease, multiple sclerosis, or those recovering from a stroke often struggle with coordination and balance. The Alter G allows them to walk without the fear of falling, helping to build confidence and improve neuromuscular function. - Chronic Pain and Arthritis Sufferers
For patients dealing with arthritis, chronic joint pain, or degenerative conditions, walking and exercising can be painful and difficult. The Alter G reduces stress on the joints, making it easier to stay active, improve flexibility, and reduce stiffness without aggravating pain.
