AlterG® Anti-Gravity Treadmill®

We’re Social. Follow Us.

Armor Physical Therapy is the only company in SW Michigan to have the AlterG® Anti-Gravity Treadmill® available for patients and clients to use for rehabilitation and sports performance.  As a leader in out-patient orthopedics physical therapy in the area, Armor PT believes that the addition of the AlterG has added a new dimension to the customized treatment plans we provide our patients.  AlterG’s NASA-patented Differential Air Pressure (DAP) technology applies a lifting force to the body, reducing weight on lower extremities and allowing precise unweighting – up to 80% of a person’s body weight.

Whether you are someone with degenerative joint disease wanting to walk pain-free, recovering from a post-operative procedure or training for a marathon, the AlterG enables faster rehabilitation, active recovery, and higher-level workouts with reduced body weight.


The use of the AlterG as part of a compressive rehab program is appropriate for many different conditions or diagnoses including:

  • Post-operative or post-fracture rehabilitation
  • Lower extremity stress reactions or stress fractures
  • Repetitive over-use injuries or syndromes (e.g., tendinitis/bursitis)
  • Apophyseal injuries (e.g., Osgood-Schlatter’s/Sever’s Disease)
  • Plantar fasciitis or fasciopathy
  • De-conditioning or balance concerns
  • Degenerative joint disease of the hip, knee, or ankle

Self-Pay Training

We offer individuals in the community the opportunity to use the AlterG treadmill as part of their training program to achieve their personal goals.  Whether you are trying to qualify for the Boston Marathon or a Triathlon World Championship or have struggled with being over-trained in the past, Armor PT now has a state-of-the-art answer for you in Kalamazoo, Michigan!
