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

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.

Before knee replacement surgery I needed to choose a physical therapist. I wanted one close to home since I would need to be driven by family 3 times a week for several weeks. Ivy Rehab was fairly new and close to my home so I chose them. Christine greeted me with a smile every visit. I was blown away by the care, patience, knowledge and expertise the physical therapists, Steve and Alex, showed me. They worked me hard but never more then I could handle. The space is clean and well equipped. My sessions were 1 hour but if I was struggling they never hesitated to spend extra time with me. I couldn’t have gotten my mobility back without their encouragement and positive attitudes. I’m so grateful I chose Ivy Rehab and highly recommended them.

I received great physical therapy here at Excel. The front desk reception and all the therapists were very warm and friendly, and the atmosphere seemed supportive and energetic. My therapist, Nick, was very thorough and paid close attention to the guidance from my orthopedic doctor to program my treatment. He answered all the questions I had about the purpose and function of my treatment, modeled the movements when necessary, and was extremely responsive to my needs for continuing the work at home. While I am glad that my issues (Lumbar spine and SI joint issues) have been resolved, I would certainly return to Excel for any physical therapy needs in the future!

I came Ivy rehab for a hip issue and the care that I have received has been second to none. My therapist Victoria is amazing and she got my hip feeling much better. The entire staff is extremely nice and welcoming. If you are in need of physical therapy, do not hesitate to contact Ivy rehab.

I saw Lauryn for a year to recover from an ACL tear, and I have nothing but great things to say! I’m feeling fully recovered. Lauryn is extremely knowledgeable, a great motivator, super kind, and very personable. I always felt like I got dedicated 1×1 attention from her. I would highly recommend her to anyone! As a whole, Ivy is great. They offer a car ride to/from appointments, their assistants are just as knowledgeable as the PTs, their equipment is in great shape, etc. They take care of all the small stuff so that you can just focus on your recovery. The best part about Ivy is their staff. They’re so friendly and positive. It’s a great motivating environment. Special shoutout to Liz at the front desk! She’s the best. Overall I would highly recommend Ivy to anyone!

Ivy Rehab has been incredible for my daughter Madeline! She’s been coming since August and seeing Steve & Kirsten. They are so patient with her (she’s only 7) and she’s making so much improvement. Liz at the front desk is so accommodating and helpful with booking. Highly recommend Ivy for all PT needs!

After surgery to repair a ruptured achilles, I specifically asked my surgeon for a recommendation of a good physical therapy group. He suggested Ivy Rehab and I am so thankful! The employees of Ivy Rehab are incredibly nice and have made me feel very comfortable during my therapy sessions. They welcome every patient who walks through their door. They work together to make sure patients are receiving the care they need and are attended to. I can't say enough about my physical therapist, Chandree. Chandree has done a great job helping me regain flexibility and strength in my achilles. He has gone above and beyond to address other issues that have cropped up along the way. He is very knowledgeable and keeps me well informed of my care plan. He really enjoys his job and is truly concerned about helping his patients. Chandree, I appreciate all you have done for me! If you are in need of physical therapy, I highly recommend Ivy Rehab Physical Therapy!

I have experienced many types of so called rehab. They all seemed to say they could help you with whatever ailed you at the time. Even though time is important in the healing process, wasting my time is not. I have found this to be true in a lot of the agencies I have attended. . However, with Ivy their knowledge is impeccable and their hands-on approach is A number one. In short, they have it all.

Highly recommend Ivy Rehab on Green Level. Great people. I worked with Ethan. From day one, every diagnosis he made and every decision he chose to get me back to a pain free state has been flawless. He is very perceptive and keen to listen to his patients and understand the issues well. His skills in identifying the root cause and matching that with the perfect treatment to get lasting results and set his patients up with routines that allow them to quickly recover is impressive. Wish I had gone here sooner. Very happy that I chose this team and have recovered well. Thank you Ivy Rehab!

My experiences with John Finneran and all of his Physical Therapist are absolutely wonderful. I actually LOVE them all more then family. I’ve been with them many years and would never go to anyone else. If need be when I moved to Florida I will either fly back to Island Park if needed or fly him to Marco Island. I could go on and on about John and his group as they treat me like gold. Thank you all keep up the GREAT work. ❤️

We have been going to ABC Pediatric Therapy for 5 years for speech and my son loves it. He's so excited to go twice a week. Miss kimberlin has seen him for 5 years he's made wonderful progress. We now also go for OT there as well and he is making wonderful progress in that as well.

There is no one you can go wrong with at Ivy Rehab. The ladies at the front desk are incredibly kind and able to navigate unique schedules to ensure you get the help you need. All of the staff is warm, informative, helpful, and friendly. This includes both the therapists and assistants. Special thanks to Joe, Steve, and “V,” for helping to get me back on my feet! 10/10 experience. I could not recommend this place, staff, and environment more.

I came in with severe hip pain and discomfort. I was barely walking! I have seen real improvement over the past couple of months. Chris is innovative in his treatment and always encouraging! I am grateful for his help! Ski season is coming soon… I know he will get me ready!

Response from the owner:Thank you for the fantastic rating, we're so grateful! – The team at Ivy Rehab Physical Therapy – Caledonia

The staff is truly welcoming and friendly. Out of all of the Physical Therapy offices I’ve been to, this is by far the nicest environment. They are very clean and sanitize all of their equipment. The take the time to stay up to date with holiday decorations that add to the atmosphere. I highly recommend if you’re looking for a peaceful, supportive recovery. 🙂

I can't recommend this place enough, if I could rate higher than 5 stars I would. The team here at excel is truly amazing and they "excel" in what they do! I had the pleasure of working with Nick R as my therapist and he went above and beyond. I didn't know if my ankle would ever be the same after my surgery last year but Nick helped me thru it, from when I was on crutches to fully sprinting again. Everyone at excel is there to help you and achieve things you didn't think possible, thank you so much excel therapy!!!

My daughter started going to Leaps and Bounds for feeding therapy at 10 months old. I was amazed at the progress that she made, and I was very impressed by how Jenny engaged with my daughter. Within 8 weeks, my daughter went from refusing to eat anything (purees, solids, etc.) to trying almost anything and actually swallowing it. I am forever grateful for what they did! She just started speech therapy with Kathleen. The office staff and therapy professionals are truly wonderful people!

Thanks for the help with our grandson Jarvis. I will keep an ear on his vocabulary development and get back to you if we don't think it's improving. Thanks again for putting our concerns at ease.

I've developed a good feeling , about my physical therapy sessions ! Doctor "Joe" has applied techniques , THAT ARE HELPING ME! He participates , in my treatments ,and he DEMONSTRATES , the exercises HIMSELF (not just telling me). "Watch How I Do It" , he will say! Seeing is Believing & I'm more confident , after SEEING HIM , DO what he is asking ME to do! Another remarkable aspect, of my progress, is "Dry Needling" ! I am DECLARING , that this treatment , in combination with a focused stretching routine, IS HELPING ME ! I'm also appreciative , for the guidance & help offered by "Holly", who is the other therapist, on the Excel Team – I'm happy that I have the opportunity , to avail myself , of their genuine Caring, Knowledge, Training and Attentiveness , that they DELIBERATLY OFFER , in my behalf – My Chronic Spine Pain , is becoming more tolerable and I'm ENJOYING , that FEELING of PROGRESS ! THANK YOU , to the entire Excel Team, for Helping Me – "Luke"

What a refreshing experience! My father has fell on some hard times lately and I have been trying to find a PT to help with his everyday functions. I called the North wales location and spoke to Will. Impressed would be an understatement. This guy is a rock star. He explained inside and out of how my insurance would be billed and even went through step by step of how and what would be tested and examined in the initial meeting. He went on and broke down the way the therapist would build a tailored made routine that would be tracked daily so my dad would not hit any plateaus so he can maintain steady improvement. What was even more awesome is that I called the wrong location but Will said he can still take care of all the paperwork for me and forward it to the closest location near my father. I have been a business owner for 20 years so this experience really hit home. I have never had an easier time with setting up a medical service or any type of service come to think of it. You can tell this guy is a wizard of his craft and sharp as a tack with his confidence and passion oozing through the phone.
