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.

Excellent4.8★★★★★ review us on ★★★★★ Excellent PT group. Aaron and the office staff helped my daughter and I deal with our PT needs in a very individualized way. My daughter was dealing with a specialized foot issue and they were able to help her move forward and easily get through a vacation in which we averaged 20,000 steps a day. Office vibe is excellent and positive. Staff is wonderful from top to bottom. They also accept most insurance pans.Response from the ownerThank you for taking the time to share this review, it means so much! – The team at Excel Physical Therapy – Westfield – East Broad St ★★★★★ A great place where the staff are very positive and always patient. They worked closely with my doctor to make a plan that was perfect for me. Kept me up to date the whole way through, as well as explaining each step so that I could understand.

They truly know their stuff there and have the equipment to help almost anyone succeed. I’m happy I was able to recover with such a team backing me up. I wasn’t always the best with making my payments, but it was super simple and they work with you if you can’t right away.

I was referred to physical therapy and found Joe at Excel. One appointment — that’s right — one appointment and I already had relief thanks to dry needling and some neck stretching. I was in shock that I had been in so much pain for so long and I felt better almost instantly. Joe listens, explains, and demonstrates what he wants me to do.The entire office has a “family” feel and everyone is so nice.

She worked with me on strengthening my lower back for about a month. I started there with Back pain and numbness down my right leg- I ended with absolutely no numbness or pain. Connie is also a very warm and positive presence that made each appointment a delight.Response from the ownerYour kind review made our day, thank you so much! – The team at Ivy Rehab Physical Therapy – Princeton ★★★★★ I’ve been struggling with a bulging disc and sciatica pain radiating down my leg for almost a year now. At times, it was so painful I couldn’t even walk more than a block, and getting a full night’s sleep was impossible with the pain.At first I tried Spear for physical therapy—my first time in PT ever—and it just wasn’t for me. While my care was okay, it reminded me of my college gym—a place for athletes (not me) that felt sort of clique-y.After a few months, I switched to Park Sports PT, and oh my god, night and day difference. My PT, Megan, and I immediately started talking about musicals and I could tell the vibe was so much more welcoming. I also noticed how much more carefully she watched my form while exercising, and gave me corrections. She also gave me manual treatments (Theragun and soft tissue massage), which my previous PT had never done and has made a big difference in how much I’m able to accomplish during my appointments.It’s been almost five months now since starting at Park Sports, and I’m doing so much better—I’m a few weeks from graduating! I couldn’t recommend the team more, not only Megan but the whole team (shout out to Amelia, Tyra, Taden, Ellis, and Emanuel!). Not only was my physical therapy itself excellent, but they helped guide me through two epidural steroid injections and are helping me with a game plan for what’s next when I graduate. Truly a 10/10 experience!Response from the ownerIt’s great to hear this feedback! Thank you for taking the time to share your review! – The team at Park Sports Physical Therapy, Brooklyn – Williamsburg ★★★★★ When I was referred to IvyTherapy I was physically broken. I was constantly in pain and had limited use of my right shoulder, right hip, and left shoulder. Aaron went to work on me providing individualized, patient centered care. Aaron takes the time to understand each patient and what they hope to accomplish from the physical therapy. Aaron works with patients to accomplish their goat. Aaron is very knowledgeable and understands the underlying causes of pains and limited mobility.Before I started physical therapy with Aaron I was sleeping in my recliner because it hurts less than sleeping in my bed. I have one more physical therapy session left and I’m sleeping in my bed and has been pain free. I have maximum use of my right shoulder, right hip, and left shoulder and no pain. I would strongly recommend Ivy Therapy and Aaron for all you physical therapy needs.Response from the ownerHearing this feedback means so much to us, thank you for sharing! – The team at Excel Physical Therapy – Westfield – East Broad St ★★★★★ I was in leg pain. My doctor sent me to Ivy Rehab. I now am free from pain, thanks to Brian Guardado’s skill, knowledge, and patience. Best wishes to Brian, his family, and staff and to all patients who will be helped by him.BillResponse from the ownerThank you for sharing this with us! – The team at Ivy Rehab Physical Therapy – Indian Trail js_loader
