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.

Seniors seeking a safer way to stay active and independent

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.

If you’re recovering from surgery, or looking to avoid surgery, this is your place! Their staff is knowledgeable, courteous, and encouraging. They listen to you, modify any exercise for your specific situation and work with you until a resolution is found.

I’ve been through pelvic floor, hip, and elbow treatments including manual therapy, dry needling, stretching and strengthening. I will never go anywhere else now.

My daughter has been in physical therapy here for almost 3 months and has progressed amazingly!!! Our pediatrician referred us here and were so happy with them! They have a friendly staff, we LOVE our therapist, Brittany, and they can be flexible with appointments.

My experience with Synergy was great before my operation Hayley got rid of my plain in my back and leg. So I went back after my surgery and requested to go back to Hayley she did a great job getting my strength and my balance back with exercise program at Synergy and home exercise they gave me to do at home. I still have 6 months to finish healing to go yet. But for now I'm very pleased with there work. Now for the staff they all were very nice and helpful. Special thanks to Hayley and Kyle works at the front desk with appointments and insurance questions very helpful 👍

I had the pleasure of working with Ross as my physical therapist at Ivyrehab for the past month, and I couldn’t be happier with the progress I've made. From the very beginning, Ross knew exactly how to address the lower back pain that had been troubling me. His expertise and personalized approach to my therapy sessions were evident in every visit.

Ross's professionalism, knowledge, and dedication to his patients truly set him apart. He designed a tailored program that effectively targeted my pain and gradually strengthened my back. Thanks to his guidance, I’ve seen significant improvements in my mobility and overall comfort.

The facility itself is well-equipped and welcoming, with a friendly and supportive staff. I highly recommend Ivyrehab and especially Ross for anyone seeking top-notch physical therapy care.

I just got discharged today. I am forever grateful for Ivy Rehab for having easily available appointments. I got hit with severe vertigo and what may have been the worst time possible for me. I found that my therapists Dan and Matt really listened, they pushed me, but not to my breaking point, they were incredibly knowledgeable, they could tailor everything to me, they were kind, encouraging, and fun. This place was great and every therapist was amazing with their patients from what I could hear. Even when frustrated with myself, I always had a smile on my face here. I also felt like had great support in my therapists here. I highly recommend this place if you need physical therapy. I can't imagine any place better.

Absolutely loved the experience here! Front desk was excellent in scheduling my mom. The doctor was very knowledgeable and helped my mother a ton. It is very helpful that the therapist also spoke Spanish to avoid translation services. The assistant would also try her best effort to talk Spanish as well. Overall I would rate 10 stars if I could!!

I goofed when filling out the first survey form you sent me! Eric at the Knotbreak Location in Salem was a great therapist! He has a great sense of humor and put me at ease on day 1. I would recommend LT to anyone…they know what they’re doing! I also worked with Kelli, TJ, Chris and Marly, but Eric was the main one who worked with me. My back and I thank you very much! 💯😊

A week into my PT and Ivy Rehab with AK and his team have helped me so much. I am in almost zero pain from my meniscus knee sprain after 4 sessions. I always feel welcomed and cared for when I am there and they even go beyond their jobs and make sure they get to know you.

I had an incredible experience this summer at the Midtown Hoboken location. Skyla was absolutely amazing—professional, knowledgeable, and so supportive throughout my entire rehab process. Thanks to her expertise, I’m feeling back to my pre-injury self and couldn’t be more grateful. The whole team at the office made me feel comfortable and cared for every step of the way. Highly recommend this place to anyone in need of physical therapy!

Ms. Amanda is the most incredible speech therapist we could have ever asked for. Both my children, Sam and Alex, worked with her over the past 6 years. During that time we have seen tremendous growth with not just my children’s speech but also their cognitive and social emotional skills because Ms. Amanda taught them with love. She challenged them to reach their potential and she taught me how to be a better parent in the process while I watched her work her magic. We will forever be grateful for how Ms. Amanda goes way above and beyond her job description every day. I honestly don’t have the words to fully describe our gratitude and her talent. Ms. Amanda is incredibly loved by us, and we will never forget the positive impact she has had on our lives!!! Thank you so much!

My friend recommended Excel PT for my back issues and I couldn’t be happier. Joe and Holly are the best. They give you individualized attention, their knowledge is outstanding, the atmosphere is welcoming and friendly. The receptionists are the best, as well. They make you feel comfortable making appointments, rescheduling, insurance issues, etc…. I’ve had dry needle therapy with Joe and it helped a great deal and cupping and tens unit with Holly and it helped greatly. I feel like PT at Excel with Joe and Holly really made a difference in my back health! I would highly recommend them!
