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 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.Response from the ownerWe’re so thankful for your kind words and positive review! – The team at Excel Physical Therapy – Westfield – East Broad St ★★★★★ Physical therapy can be tough, but Alex and everyone at the Somerset location made it such a positive experience.

Thank you all!!Response from the ownerThank you so much for sharing your thoughts, we appreciate you! – The team at Ivy Rehab Physical Therapy – Somerset ★★★★★ My time at Ivy Rehab was the best PT experience I’ve ever had. Every employee there exemplifies the epitome of kindness and care with an expertise that is unmatched. They all contributed to advocation for my treatment. I was treated by both Katherine and Patrick, and learned so much about my body and how to treat its ailments. Grace at the front desk was always there to greet me with a smile and assist me with scheduling. Christian was always there to make sure everyone was comfortable, things were clean, and to lend a helping hand when things got busy. Overall, many fun times were had and I will never forget my experience there and will take with me all the things I learned about caring for my body. If (probably more of a “when”) I ever get hurt again, I 100% will be coming back to Ivy Rehab. Thank you from the bottom of my heart for such a good healthcare experience.With love,Your “cousin” EmilyResponse from the ownerIt’s great to hear this feedback!

My second time working with Megan and she’s been so thorough, thoughtful, knowledgeable, and patient. All of the staff are A+!Response from the ownerThank you so much for your positive feedback, it means the world to us! – The team at Park Sports Physical Therapy, Brooklyn – Williamsburg ★★★★★ At Excel I had the opportunity to work with Jessica the physical therapist. She was extremely knowledgeable, very thorough with my examination, and had a lot of ideas to help with my specific treatment. I knew I was in good hands with regards to my PT sessions. And even after a short time, I am having such positive results. I would recommend Excel to everyone I know. Jessica is truly a wonderful physical therapist and really knows her stuff. ★★★★★ After breaking my wrist last July, Ive had the most wonderful experience in my healing process at the Ivy Rehab in Princeton NJ working with Physical Therapist Connie D. She has been working with me twice weekly. Connie is friendly, knowledgeable, patient, encouraging, and seeks effective ways to gradually facilitate my healing and above all strengthen my wrist and deal with carpal tunnel and nerve issues caused by the fall. You might say, well this is what she’s supposed to do as a therapist, but you should understand that losing mobility and strength is very difficult emotionally and psychologically for me since I work full time and am a caretaker for my husband. I tend to lose patience with the slow healing that nature dictates at my age, and lose confidence that the situation will ever improve. But Connie’s special talent is that she is a positive encouraging force in my life right now and she explains why it takes so long and proves through changing my exercises to target my goals and monthly testing that I am indeed improving. I have also worked with Bob at the Princeton office, and he too is knowledgeable, friendly and patient. In fact the whole office from reception through to every aid have been pleasant, upbeat and extremely heloful and welcoming. But Connie is a very special person, she cares very much about all those she works with and she has a delightful sense of humor, a very important and appreciated quality for me and others working through issues more serious than mine. She truly lights up the place.Response from the ownerThank you for the 5-stars! It means so much. – The team at Ivy Rehab PT, Princeton ★★★★★ I normally see Melanie at this location and she is great! She always goes above and beyond and really cares about her clients. I would recommend to anyone looking for a physical therapist. ★★★★★ The person I had Amy was very pleasant and very knowledgeable and insightful.

I came in for prehab for an ACL injury and the progress I’ve made has surpassed all my expectations. Can’t recommend Park Sports enough!Response from the ownerThank you for your kind words; we appreciate your feedback! – The team at Park Sports Physical Therapy, Brooklyn – Williamsburg ★★★★★ 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.
