The AlterG Anti-Gravity Treadmill M320 is the market-leading choice for body weight support treadmills because its patented differential air-pressure chamber provides exceptionally precise, repeatable unweighting and a sealed environment for gait training. Compared with harness-style systems like the Biodex Gait Trainer 3 or LiteGait LG500, the M320 delivers finer control and a stronger evidence base for clinical outcomes, though it commands a premium price—an investment often justified by reduced treatment times and strong manufacturer service and training.

AlterG Anti-Gravity Treadmill M320
The AlterG Anti-Gravity Treadmill M320 is the premium choice when precise, finely graded unweighting and comfortable cardiovascular training are required for children, using differential air-pressure technology to offload bodyweight without a bulky harness. While it is a higher capital investment than harness-based systems such as LiteGait or Biodex, its unique anti-gravity capability can accelerate rehabilitation in neurologic and post-operative pediatric cases and often reduces therapist hands-on time per session.

AlterG Anti-Gravity Treadmill M320
The AlterG M320 is the market leader in anti-gravity treadmill technology, delivering highly precise body-weight support via differential air pressure that enables early, high-quality gait training while minimizing joint load. Compared with mechanical unweighting systems in this list, AlterG provides unparalleled fine-grain weight adjustments and patient comfort, albeit at a higher capital price — an investment that many centers justify through faster patient throughput and reduced secondary injuries. For neurological rehab it is especially advantageous where gradual load progression and safe early ambulation are treatment priorities.

The AlterG Anti-Gravity Treadmill M320 dominates where precise body-weight support and unweighting are required, thanks to its patented differential air pressure technology that enables finely graded partial-weight bearing during gait training. Technically superior for high-level rehabilitation and performance return, it commands a premium price and complements rather than replaces rail-based transfer systems, offering capabilities other products on this list (HUR, Biodex, Woodway, TecnoBody) cannot match for safe progressive unloading.
