The Alter G gives patients a way of non-painful, controlled weight bearing early in the recovery period.

Dr. Tyner can monitor a patients' weight bearing restrictions by selecting the appropriate percent of body weight by a surgeons protocol. 

The Alter G uses an air chamber to reduce the amount of force on clients' joints. The allows Dr. Tyner to carefully monitor ones overuse injuries as well as allow for low impact training for those with joint issues. 

How it works?

  • The Alter G has a precise unweighting technology, the AlterG Anti-Gravity Treadmill allows you to push your physical therapy rehabilitation and training further than ever before. You can: Reduce gravity's impact by selecting any weight between 20% and 100% of your body weight by 1% increments.
    • Allowing you to walk or run with no pain while maintaining a normal gait
    • Reducing stress on joints and injured areas of your lower body
    • Giving you the confidence and ability to run or walk longer and recover faster with less pain
Studies show that an earlier return to activity prevents atrophy of supporting muscles, decreases swelling, and improves outcomes.
