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.

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 can’t say enough good about the team at Ivy Rehab PT on West River! I was seen by all of the PTs there (Emily, Haley and Kyle) and they’re all knowledgeable, competent, kind, good communicators, and great at adapting and problem solving. Brooklyn who does all of the scheduling and billing is so helpful, kind and figures out anything that’s thrown at her. I’ve been to PT a few other times/places, and this has been my favorite experience so far. I hope I don’t need PT again, but if I do, I’ll definitely come back here.

I came in with severe hip pain and discomfort. I was barely walking! I have seen real improvement over the past couple of months. Chris is innovative in his treatment and always encouraging! I am grateful for his help! Ski season is coming soon… I know he will get me ready!

Response from the owner:Thank you for the fantastic rating, we're so grateful! – The team at Ivy Rehab Physical Therapy – Caledonia

I never in my life had physical therapy before, until one day my right shoulder started bothered me. My Orthopedic doctor referred me for Physical Therapy. I searched for a location near to my home; called two or three. I found the best place any one can go; the reason being is that the person who answered the phone Christina, sound like an angel, sweet, smiley, pleasant. Immediately I booked my appointments for a couple of months. The doctors are the best anyone can find, sweet, smiley pleasant, caring, sympathetic, helpful. Dr Steven and Dr Alex, and an intern William, made me feel like family, taking care of me day after day. After a couple of months, no surgery was needed and I'm back to normal. I was getting used to see the patients and doctors. Once the treatment was completed, the following week I felt that something was missing not going any longer to IvyTherapy. I missed all of them. You couldn't be in any other place better than IvyTherapy. The best of the best!!!

The staff is super friendly and professional. Helen made the scheduling so easy for me. Connie Darrow was my therapist. It was a great, personalized experience. Connie helped me get rid of my shoulder and back pain and taught me how to avoid injuries in my daily routine. She was always on top of my recovery progress.

This place is great! Bobby addressed the variety of issues I had and got me running and exercising pain-free about a month after my first visit.

I had a wonderful experience at Excel Therapy. I went in after a knee replacement and had Nicholas as my therapist. He was so professional, extremely knowledgeable and caring. I was concerned that while doing exercises I would totally be on my own, not knowing if I was doing them correctly . I have to say Nicholas always checked on me to be certain I was properly doing all exercises.He always changed my exercises depending on what I needed at that time for a fast recovery. I could not be more pleased with results of my therapy at Excel and would certainly return in the future if needed.Thank you for the wonderful care.

My husband Joel was seen for sacroiliac pain by John Finneran who did a very thorough evaluation. He then worked on him to alleviate the pain and Joel had good results! John also gave us an email of videos of exercises that Joel can do at home to help improve his situation. They’re easy to follow and help ease the pain. John is kind and very professional. We recommend him highly!

I've had previous experience with Ivy Physical Therapy. Professional and courteous all the way through the process. The gentleman I was working with today was thorough. Asked many questions that were pertinent with my issue. One thing, was asked if I had trouble lifting, I think I said no. If you could add to my record that, yes, I do have issues with some lifting, even light weight.. I'll be sure to bring that up next appointment. Thanks again.

Thank you to everyone at Park Sports Physical therapy for getting me strong and (most likely) helping me avoid hip surgery after a running injury! Taden is the best – he’s super knowledgeable and friendly and helped make me feel comfortable with exercising even though I have a pre existing condition that makes gaining muscle difficult. Also shoutout to Tara, Olga, and the rest of the team for helping me feel better and whipping me into the best shape 💪💪💪

Had an incredible time with Excel Physical therapy staff in KOP, Catherine was incredibly helpful with my progress there in a short amount of time! Would recommend to anyone!

Response from the owner:Thank you! We are excited to hear about your progress and the positive experience you had at our KOP clinic.

I went to Ivy after previous physical therapy was not working for me. I was in agonizing pain with 2 rotator cuff tears and a SLAP tear. Scott provided one on one private sessions twice a week with videos to take home to make sure I was doing the right stretches and exercises. I now feel I won’t have to have surgery and can get back to normalcy. I realize these types of injuries don’t heal, but I have confidence I can go back to my day to day life.
