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 am treating for a torn rotor cuff on my left shoulder. My therapist is Nick who is very knowledgeable and takes time to explain everything and the correct way to do the exercises

Response from the owner:Thank you so much for your positive feedback, it means the world to us! – The team at Ivy Rehab Physical Therapy, New Hyde Park

I decided to try Ivy Rehab in lieu of some other, more common PT places in the area. I was glad I did. The team there is great. They are professional, knowledgeable and friendly. The center is also very clean and welcoming. Scheduling is easy and they are very accommodating to one’s busy life. I made progress with my neck issue so thank you to the Ivy team. I would definitely recommend.

I can't recommend this place enough! From the moment I walked in, I was greeted with warmth and professionalism. The entire staff is incredibly knowledgeable, attentive, and dedicated to helping each patient achieve their goals.
My therapist, Caroline, is outstanding. They take the time to fully understand my injury and developed a personalized treatment plan that not only addressed my pain but also helped me regain strength and mobility. Every session is well-organized, and the staff is always patient and encouraging, making sure I felt comfortable and confident with the exercises.

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!

Response from the owner:Thank you for your kind words; we appreciate your feedback! – The team at Ivy Rehab Physical Therapy – Willingboro

I can’t recommend Ivy Rehab Excel Physical Therapy enough! My experience with Debbie was nothing short of transformative. After undergoing three femur fracture surgeries, I was apprehensive about my recovery, but Debbie’s expertise and dedication made all the difference.

She not only guided me through the rehabilitation process with a tailored plan, but she also identified issues that my surgeon had overlooked, ensuring a comprehensive recovery. Debbie’s encouraging approach and deep knowledge of physical therapy empowered me to regain strength and mobility faster than I ever expected.

The entire staff at Ivy Rehab is welcoming and supportive, creating a positive environment that made each visit enjoyable. If you’re looking for exceptional care and personalized attention, look no further than Ivy Rehab.

I just completed my physical therapy for a knee replacement surgery. I went 3 times a week for 7 weeks. I was extremely satisfied with the experience. I know that without the therapy I wouldn't be able to get around . Both therapists I saw worked very hard to get me walking independently without pain. Every time I went I could tell I was making progress. Now I can walk at least a mile and go up and down stairs easily.
The atmosphere in the facility is very friendly and attentive. I was always welcomed when I entered. The staff kept everyone working the entire time that I was there. It was always a pleasure to go there.

Response from the owner:We really appreciate you taking the time to leave us this 5-star review! – The team at Ivy Rehab Physical Therapy – Naperville

It's been a wonderful experience going to Ivy Rehab in KOP. Not only is the staff super knowledgeable and extremely patient, they are really fun people to be around. I've had the pleasure of working with both Kelly and Tim and I couldn't ask for better! The staff are really friendly and helpful when it comes to managing appts and dealing with insurance. Even though I was coming in for chronic back issues and sometimes it was uncomfortable to get through certain exercises, I always enjoyed being there. The therapists become your friends and they help make exercising fun! I wouldn't hesitate to return if I had to…I know I'm always in good hands!

Response from the owner:We're thrilled you had such a positive experience, thank you! – The team at Ivy Rehab Physical Therapy – King of Prussia

I fell and broke my arm and destroyed my elbow end of January. I had surgery February 1. When surgeon gave the ok to begin hand/arm therapy, I made appointment with Bekah Thomas. She is wonderful. She worked with me with such patience and encouragement. After several months, I graduated today, July 9. I surpassed mine and Bekah’s goals. If you need any hand or arm therapy, Bekah is your therapist. Everyone at Synergy has been most helpful and great to deal with. I recommend them highly.

I had my first appointment with Karen. She is very professional and supportive. She successfully helped me, for the first time in years, get up from a chair without using my arms. Onward and upward!!

The Briarcliff office is a great place! It is staffed by wonderful, caring, and considerate people. It is rare to find those qualities coupled with their professionalism! Thank you Victoria for the effort and perseverance that it took to get me up and about again !

Response from the owner:We're so thankful for your kind words and positive review! – The team at Ivy Rehab Physical Therapy – Briarcliff Manor

I was diagnosed with benign positional vertigo, Matt was professional, efficient and most of all, very knowledgeable about my ailment. He affirmed what the problem was and did the proper maneuver and fixed it on the first try. I would highly recommend PTW to anyone who needs rehab. I felt horrible for 10 days, now I feel reborn.

I have LOVED my Park Sports experience. After trying several PT providers in the area, I can confidently say they’re the best. Emmanuel is the kindest, most professional, and empathetic scheduler. From the start, he set a friendly, helpful tone that cannot be understated, especially since I was nervous and on crutches when I first started. His flexibility and attention to detail have helped me fit several sessions into my schedule. Megan (without an h) is an excellent PT who brings friendly banter and careful, professional guidance to designing and explaining my treatment plan. She actively solicits and listens to feedback on what works for me and my body and adjusts exercises accordingly. Emilia and Tyra are equally friendly, knowledgeable, and helpful, and keep my spirits up if I have a tough day. As someone without any previous PT or extensive knowledge of my injury, they’ve helped me feel at home in my body and confidently walk again.

Response from the owner:That's wonderful to hear – thank you so much for sharing your feedback with us! – The team at Park Sports Physical Therapy, Brooklyn – Williamsburg

I have gone to Ivy Rehab for 2 different issues and both issues have been resolved! Thanks to Ethan for providing excellent care and support with my issues! I highly recommend Ivy Rehab!

When you go to a physical therapist after shoulder surgery, you don't anticipate that your PT will be the best part of your day! Jeff at Excel spends as much time with you as you need! He's not limited to 5 minutes for insurance purposes. He and Kelly, the other PT, provide empathetic care coupled with intelligence and expertise! There is always a positive energy coming from all of the staff, from the receptionist to the assistants to the physical therapists themselves. It feels more like a family, providing all of the support I could ever need. I highly recommend Excel of Oakland, as they hit every mark of excellence!
