What is an AlterG Anti Gravity Treadmill?

The AlterG Anti-Gravity Treadmill uses Differential Air Pressure (DAP) to create a safe, pressurized environment around your lower body. This reduces your effective body weight, allowing for walking, running, and exercising with less strain on your joints, muscles, and healing tissues — all while maintaining natural gait mechanics.

The Science Behind AlterG

Backed by clinical evidence, the Anti Gravity Treadmill® can be used to treat Orthopedics, Chronic Conditions, Athletic Performance, and even Neurological Conditions. The AlterG® Anti Gravity Treadmill® uses Differential Air Pressure technology to unweight patients and athletes to enable an unprecedented level of comfort and mobility – without impeding natural gait mechanics. The AlterG® can use gently unweight users to 20% of their body weight at a comfortable pace of 1% increments. By unweighting users to 20% of their body weight, the treadmill allows patients to perform weight-bearing exercises sooner than normal to speed up the healing process and get you back on your feet in no time! Real-time gait analytics are provided to therapists and patients in order to review movement and correct any impairment quickly.

Key Benefits for Injury Recovery, Neurological Rehabilitation, and Athletic Training

  • Start weight-bearing exercises earlier after injury or surgery
  • Safely improve mobility after neurological events like stroke or brain injury
  • Enhance athletic conditioning while minimizing risk of re-injury
  • Strengthen muscles and improve cardiovascular health without overloading joints

Who Can Benefit from the AlterG?

  • Orthopedic and post-surgical patients recovering from fractures, joint replacements, or ligament repairs
  • Individuals with neurological conditions such as stroke, Parkinson’s disease, or brain injury
  • Athletes rehabilitating from lower extremity injuries
  • Seniors seeking a safer way to stay active and independent
  • Individuals managing weight loss or chronic joint pain, who want to exercise without stress on joints

The AlterG Difference

Unlike other treadmill systems, the AlterG Anti Gravity Treadmill allows users to exercise comfortably and freely without the restriction of a harness and uses the air pressure to create a safe environment to prevent further damage and injuries in case of a fall. The fear of falling and worsening an injury can be demotivating during medical rehabilitation, but the safety of the Anti Gravity Treadmill physical therapy training can empower patients to move AND recover. If you’re experiencing mobility impairment, excessive joint pain, or you’re an injured athlete, contact us at Ivy Rehab to connect with a physical therapist and get started as an AlterG treadmill patient today.

FAQs

Do I need a doctor’s referral to use the AlterG at Ivy Rehab?

No referral is needed for private pay sessions—you can schedule an AlterG session directly. If you plan to use insurance to cover your treatment, referral requirements may vary depending on your insurance provider and location. We recommend contacting your local Ivy Rehab clinic to confirm what’s needed based on your plan. Our team can help guide you through any necessary paperwork or approvals.

How long are typical AlterG sessions?

AlterG sessions typically last between 20 to 45 minutes, depending on your individual rehabilitation goals, tolerance, and progression. Your therapist will work with you to determine the ideal session length and frequency. Sessions can be customized for recovery from surgery, injury, or general performance training.

How quickly can I start using the AlterG after surgery or injury?

In many cases, once cleared by your medical provider, you can begin using the AlterG Anti-Gravity Treadmill just weeks after surgery or injury. The AlterG allows for low-impact, controlled weight-bearing, which can help reduce strain on healing tissues and accelerate your recovery timeline. By gently reintroducing movement earlier in your rehab process, it can support a safer, more confident return to walking, running, or sport-specific activity.

My experience at Excel Physical Therapy in Englewood Cliffs was a very positive one. Cesar, Natalie and the rest of the team are friendly and attentive to their patients needs.

This is an awesome place to go for Physical therapy. Emily Fase and Hailey Anderson are 5 star Physical Therapists. Both of them are patient, kind, and communicate really well. I like how they both explain things in easy to understand ways. There are openings in this office so you don’t have to wait to get in. They are open from 7:00 a.m. to 7:00 pm. I also really like the Secretary as she is really helpful!

My physical therapy experience at Ivy Rehab was phenomenal and I would absolutely recommend them to friends and family. Maci went above and beyond to provide the best treatment plan for my plantar fasciitis, and she made sure to constantly update and adjust my treatment based on my progression. Before starting physical therapy, I was informed by my doctor that plantar fasciitis is a chronic condition that would likely take a year or possibly more to fully heal. After 2 months of intensive treatment by Maci and the team at Ivy, my plantar fasciitis improved dramatically and I completed my treatment plan. My expectations were absolutely exceeded and it is so amazing to no longer be in constant pain. Thanks Ivy!
Thank you very much to the professional staff of delaware avenue. In 2014 I was using progress PT with Dr. Jeff and his staff helped me with my left rotator cuff after operation. It was very successful. I would like to emphasize that the staff and Physical therapists are very professional, knowledgeable, and thorough with their work. Locations are very easy to reach and facilities are clean and equipped with modern technology for all kinds of tasks. Again thank you for helping me back to my normal life.
Today was graduation day. After 6 months of physical therapy I was able to walk out on my own. Prior to the fabulous work from some great therapists I was confined to wheelchairs, walkers and canes after some intense surgeries. Thanks to Jamie, Ciara, Marisa, Chris and Katina I feel great. Don’t hesitate to go to this facility you will not be disappointed. I have done several other physical therapy agencies and did not get the same results. 10 stars if I could.

My son was in speech therapy at Ivy Rehab and I would recommend them in a heartbeat. Everyone in this office is so friendly and makes their patients and families feel welcome.
