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.

I came in with a neck issue and Ethan evaluated me. He was enthusiastic and extremely knowledgeable. Ethan educated me thoroughly on exercises to help me improve my issues and tried to discover new ways to help me while in his care. I had a great experience. Thanks Ethan!

Tearing my achilles roughly 8 months ago, I knew I needed to find a physical therapist that would push and challenge me daily. Going to Excel for the first time I realized I was at the right place. My experience started from the time I walked in the door with Colleen and Kris at the front desk. Always positive and willing to help. As far as how my actual therapy went, I had the pleasure of working with both Joe and Holly. Being a competitive athlete who was a collegiate athlete and also competed in ultra marathons, jiu-jitsu, etc. I was challenged daily to get me back to my goals. If I had to rate my experience with Excel 1-10, the answer would be an easy 10. Currently back to running and normal activities with no pain. Thank you to Excel.

Hadn’t been to Ivy since before they changed names but happy to say that quality of service has only gotten better over time. The front desk is always helpful with any issues you may have, going above and beyond to help you get things resolved. All of the staff is super friendly making you feel right at home. I personally worked with Lydia & to say that she is great is an understatement. No nonsense, very compassionate towards the issues you may be dealing with and overall just pleasant to deal with. Cannot suggest Ivy enough to anybody needing to recover from injuries!

I took my daughter here for 2 months and Hannah was amazing with my daughter . She never wanted to leave . I really felt like she was able to understand my daughter. So sad that we had to transfer to a location closer to home. But if this location is near you I 100% recommend Hannah and Erica . They are amazing .

Just a great place, very clean facility and amenities. Paige and her entire staff are very friendly. I just had my last session and it was bittersweet that I'm leaving the great people behind, but leaving with a positive feeling as my knee replacement rehab could not have been any better. Highly recommend Ivy rehab for all needs. Attention to detail and the programs laid out for me was fantastic. The staff will be missed, but I'll visit them!

Had such a great experience. My son broke his leg and Jason Klein took such good care of him. Scheduling appointments was so easy. Jason made it fun for my 8 year old to do PT. I highly recommend.
Response from the owner:Hi Nate! Thank you so much for sharing you and your son's experiences with Jason. We're so happy that he was able to help him!
Everyone is great. Kelly helped me build up strength on my right side so when I had my left knee done I'd be able to handle the rehab. Walking is a good thing. Thank you so much.

After just a handful of visits to Excel and working with Aaron and Jon and the staff, I am already feeling stronger and excited to commit to my recovery with their expertise and encouragement. Aaron has already gone above and beyond during sessions to truly understand my injury and source of discomfort and to give realistic progression expectations. Their interactions with me and other patients in the office has been caring, professional and knowledgeable. It is a truly well-staffed, well-run operation and I highly recommend.
