AlterG®: unique and leading in anti-gravity rehabilitation and training

Since its founding in 2005, AlterG Inc. has manufactured high quality, medical grade anti-gravity treadmills that provide innovative rehabilitation solutions for patients and athletes.

AlterG’s NASA inspired patented Differential Air Pressure (DAP) technology utilises a special air chamber and an advanced calibration system to uniformly reduce gravitational load and gently reduce body weight by as much as 80% in precise 1% increments – without impeding natural gait mechanics. No other unweighting method delivers such unrestricted freedom of movement and unparalleled control. With unmatched precision, it combines revolutionary technology, an intuitive touchscreen interface, real-time gait analytics, and live video monitoring to enable a fall-safe environment where a patient’s body weight is supported during walking, running, and closed-kinetic chain exercise. The AlterG technology supports diverse ortho and neuro patients, active seniors, and athletes to regain mobility, and achieve performance goals sooner.

Who Does the AlterG Anti-Gravity Treadmill Help?

The AlterG Anti-Gravity Treadmill can be found in over 4,000 facilities around the world and has helped millions safely and consistently reach their goals and achieve better outcomes. A wide variety of patient populations can benefit from the AlterG systems to recover mobility, improve wellness, and enhance physical performance, making these an excellent complementary product to a comprehensive rehabilitation care plan.

While AlterG’s Anti-Gravity Treadmill is perhaps most widely known as being a cornerstone in the training and recovery of elite athletes and a standard tool for supporting gait rehabilitation following orthopaedic injury or surgery, this technology has also become increasingly critical in supporting a broad range of clinical applications, including recovery and management of neurological disease or injury. Some ways AlterG can have a positive impact on Neurorehabilitation outcomes include:

  • Enhanced motor learning and quicker access to endurance, strength, and gait quality improvements through increased access to treatment volume

  • Access to varied and increased training intensities due to a virtually fall-proof environment

  • Improved patient tolerance and comfort during sessions

AlterG has compiled a growing body of research over its nearly two decades on the market, including protocols spanning orthopaedics, sports medicine, neurological disease, chronic condition management, and much more.

The AlterG treadmill is suitable for any patient or athlete that may benefit from reducing pressure on their joints while working to regain strength or mobility after injury. A doctor’s referral or prescription is not required for use if the goal is to achieve weight loss, enhance sports performance training, or specific to other non-medical uses. A complete list of indications for reference is listed below.
