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.

  • Start weight-bearing exercises earlier after injury or surgery
  • Safely improve mobility after neurological events like stroke or brain injury

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 ★★★★★ AK, Chandree, and the many others that make up the Ivy Rehab team are tremendous. For those going through a time that is not desired, they make it fun and encouraging, and they achieve the desired result – the maximum result that physical therapy can provide. Thank you, Ivy Rehab Team!Response from the ownerWe’re thrilled to see your 5-star review – thank you so much! – The team at Ivy Rehab Physical Therapy – Naperville ★★★★★ There is just no place like Park Sports. I never thought one could have such a delightful time while treating an injury. I came to PSPT with back and shoulder pain, and within a few short weeks, I had made LEAPS and BOUNDS of improvement. My physical therapist, Megan, is so fun to work with, and Emilia is always one step ahead of me. I feel really taken care of here! And who knew I would have such a good time at physical therapy??? 10/10Response from the ownerThank you for the great review, we really appreciate it! – The team at Park Sports Physical Therapy, Brooklyn – Williamsburg ★★★★★ Had an excellent experience during several weeks of PT for my shoulder here. Joe helped strengthen my shoulder so I got back to playing pickleball. Also he didn’t hesitate to help me out on a few visits when my back and vertigo were acting up too. The friendly atmosphere and camaraderie of the whole staff made going to PT regularly a whole lot easier!Response from the ownerThank you so much for sharing your thoughts, we appreciate you! – The team at Excel Physical Therapy – West Deptford – 1007 Mantua Pke ★★★★★ Compassionate kind staff! They monitored my progress and adjusted exercises as needed. Danielle and Giancarlo in particular made P/T a veryPositive experience. I’ve been to Excel more times than I would prefer, but I always left in much better condition. Thank you!Response from the ownerWe value your feedback, thank you for your kind words! – The team at Excel Physical Therapy, Cresskill ★★★★★ Awesome Team!Taylor B. – Superb Tech! who’s been there from day one. He’s that guy that is consistently on the move. When things get busy, he kicks into next gear with impressive support. If he isn’t sanitizing used apparatuses for others to use, he is systematically supporting patients with their to-do treatments for that day. Great guy!Chris L. – Fabulous Tech! Extraordinarily patient, lord knows how many times he needed to correct my form and each time he did it with a smile. His efforts made me want to continue to push and improve in all my attempts. This guy has the presence of a silent Monk! Quiet but extremely effective. We need more like him in this profession.Tony M. – Steadfast Tech! Known for less than a month, one would say he couldn’t have made that much of an impression on me. But I beg to differ, my analytical mind as IT professional forces me to pay attention to detail unknowingly. And what I’ve noticed about Tony is his consistency and do right attitude towards patients. He takes his duties as a PT technician seriously, once Tony is assigned to you that day, and he has another patient that has completed their treatment and has exited the facility. This guy Tony will not leave you hanging and will check on your status and if he sees a questionable look on your face, like he saw on mine a week ago…. lol. He will come running to your aide. Rockstar of an individual.Absolutely grateful for their support on my journey to healing.Thank you!Response from the ownerWe value your feedback, thank you for your kind words! – The team at Ivy Rehab Physical Therapy, Chesapeake – South Norfolk ★★★★★ Everyone is super nice and dedicated to seeing patients get back to their own version of normal.

I wish I could give them more stars.Response from the ownerThank you for the fantastic rating, we’re so grateful! – The team at Excel Physical Therapy – West Deptford – 1007 Mantua Pke ★★★★★ The highly skilled clinicians at Ivy Rehab Physical Therapy in South Norfolk, Va.

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.
