AlterG Anti-Gravity Treadmill

What is the AlterG Treadmill?

The AlterG Anti-Gravity Treadmill, in most aspects, looks and works like a regular treadmill. It was developed with NASA technology to simulate the feeling of weightless walking or running. The AlterG was created with an advanced air pressure regulation system creating a lifting force, which allows you to reduce your weight by 20, 30, 50 percent, more or less depending on your need, without altering your natural body movement. The AlterG enables individuals who have been weakened or impaired by illness or injury to improve mobility and health. It helps recover from injury & surgery more effectively and overcome medical challenges that limit movement.




How Does it Work?

The AlterG Anti-Gravity Treadmill creates a lifting force that allows for ultra-low impact. Once you are fit on the machine, the belt starts moving and you’re free to adjust the speed and incline, as on a regular treadmill. Only now, you can also control how much of your weight you want to feel. You can reduce your weight to about 20 percent, roughly the same sensation astronauts experience on the moon. With less gravity to fight, exercise becomes pain free. The strain on your knees, hips and lower back disappears, making it easy to maintain mobility and range of motion. This will allow ease and comfort while walking or running, while reducing the amount of impact on your joints.

For Rehabilitation:
- Sport specific conditioning programs
- Stress related injury
- For High Level Athletes
- For Performance Enhancement
- Lower body injury & surgery rehabilitation
- Rehab after total joint replacement
- Neurologic retraining
- Gait training in neurologic patients
- Strengthening & conditioning in older patients
- Aerobic conditioning
- Weight control & reduction

Under a physician’s prescription for physical therapy, the Alter-G may be covered under your insurance plan. Please call for info and more details.

Computerized Video Gait Analysis

Body Werks Physical Therapy, Ltd in partnership with Motion Werks, is one of only a handful of practices in the United States to offer Computerized Video Gait Analysis. Through a sophisticated network of computer sensors placed on the lower extremity and video cameras to record the walking/running process, abnormal body movement can be critically evaluated and its influence on other parts of the body determined. The ability to show problems caused by the foot and lower extremity in motion means even more accurate diagnosis and treatment of painful conditions.

In general, gait analysis is the study of the body’s motion during normal running and walking. It typically focuses on foot and ankle motion but can also assess motion at the knees, hips, trunk, and arms. Our precisely positioned video cameras will record you walking or running on a treadmill. The frame-by-frame video helps us make a more precise assessment of your biomechanics. The process involves evaluating the leg’s anatomical structure, muscle flexibility and strength – assessing how those factors influence the way a person runs or walks. Weak or inflexible muscles, if stressed by a lot of running or walking over time, can lead to injury. Even a simple movement such as an excessive arm swing can make a difference in the performance of a competitive runner, adding a precious second or two to running times.

Furthermore, gait analysis allows us as clinicians to pinpoint your problem areas and develop a comprehensive physical therapy plan of care. It also helps our podiatrists build custom foot orthotics and prescribe proper footwear in order to prevent progression of bony abnormalities in the foot/ankle and decrease other joint pains affected by abnormal foot function.

Called Gait Analysis, the benefits of this new technology include…

  • Decreasing pain caused by degenerative conditions such as Osteoarthritis & Osteoporosis
  • Prevention of specific muscle, bone and joint problems at remote sites due to Overuse injuries.
  • Postponement or prevention of surgical procedures on the foot and other areas of the body such as the lower back, knees, hips, etc
  • Providing runners with the framework to become more efficient athletes in motion.
