Recovery is a unique process that’s different for everyone. While some patients may have no trouble at all with certain exercise and physical therapy routines, others will face restrictions. Patients who struggle with weight, joint pains, fatigue, immobility, or other limitations can all be treated effectively and more comfortable with the use of a unique rehabilitation tool—the Boost Anti-Gravity Treadmill offered at MOTUS Specialists Physical Therapy.

The Boost treadmill offers a weightlessness similar to being in water, without the resistance. It allows for full range of motion and normal running technique. The result is a treadmill that makes exercise accessible to everyone, a tool we can use to better serve patients with varying physical limitations and needs.

What is an Anti-Gravity Treadmill?

In shAn anti-gravity treadmill is designed to give you the same exercise tools as a regular treadmill, while using advanced technology to decrease your body weight. This effect is done by using an air pressure technology. The technology was initially developed by NASA for a treadmill that was designed to allow astronauts to exercise in space.1 This piece of equipment used air pressure technology to simulate weight in low gravity situations.

The Boost Anti-Gravity Treadmill takes the same science and tweaks it in order to do the opposite. Instead of increasing weight, it makes the user feel less weight.

The Boost Anti-Gravity Treadmill has an anti-gravity chamber that is attached to normal treadmill functionality. The chamber encases the user at the waist and uses differential air pressure to create a sense of weightlessness from the waist down. With up to 80% less body weight, users can use the treadmill with easier movements and less stress on joints.

The Benefits of an Anti-Gravity Treadmill

This unweighting treadmill makes recovery faster and more accessible for patients who are limited in their abilities. For instance, this tool allows for more comfortable exercise. The weightlessness felt on the anti-gravity treadmill takes pressure away from the joints, which means that patients who are overweight may have a much easier and more comfortable time working out. One study by Shantanu Patil et. al.2 concluded that the use of an anti-gravity treadmill provides “controlled decrease of the joint forces and might be an effective tool in the rehabilitation of patients following lower‐extremity surgery.” Whether joints are under stress from surgery or poor joint health, the Boost Anti-Gravity Treadmill provides an easier and more comfortable way to exercise.
Because the treadmill makes exercise easier for all ages and body types, it has an added benefit of being able to delay the progression of osteoarthritis with movement and physical therapy.

In general, movement is easier with the anti-gravity treadmill. Users will experience a higher range of motion, and will notice that it takes much less effort to run. The experience is safe and controlled, which adds to the comfort and also decreases the risk of injury or reinjury. Elderly patients, patients struggling with weight, and anyone who has issues with fatigue and immobility can finally enjoy the benefits of exercise with weightless running on the anti-gravity treadmill.

Even patients who are not limited in their strength and mobility can take advantage of this rehabilitation tool at MOTUS Specialists Physical Therapy. Professional athletes or weekend warriors who have suffered an injury can use the anti-gravity treadmill to enjoy immediate, pain-free exercises post trauma, thus recovering faster.

The Boost Anti-Gravity Treadmill exceeds the advantages of other unweighted rehabilitation tools by providing a workout that does not limit range of motion. The chamber is spacious and uncombersome, and the upper body is left in the open, so you can run with natural movements and thoroughly condition your muscles.

Anti-Gravity Treadmill for Sports Performance

The Boost treadmill has uses that extend beyond rehabilitation and accessibility. Athletes and trainers have found that this technology can be used to enhance performance and training, as it allows athletes to run faster, harder, and longer. With a max speed of 18 mph, the Boost treadmill is perfect for overspeed training.

As mentioned above, the benefits of the anti-gravity treadmill are also relevant in the rehabilitation of athletes. Being able to get right back to regular movement without delay after an injury leads to faster rehabilitation, and less time downtime for athletes. (See our article on the M.E.A.T. treatment for more on that!) There is also a lower risk of re-injury when exercising in the controlled conditions of the anti-gravity treadmill.

Anti-Gravity Treadmill for Rehabilitation

Having the Boost Anti-Gravity Treadmill on sight at MOTUS Specialists Physical Therapy allows us to provide safer, comfortable rehabilitation to a huge range of conditions. Oftentimes physical therapy and recovery is very difficult for a person because of the stress and pain that can come with working the baody post injury or surgery. With the weightlessness of the Boost treadmill, you can get the rehabilitation benefits of exercise in a way that’s effective and safe.We’ve already discussed how this tool takes pressure off joints for a safer and more comfortable rehab routine. This treadmill is also beneficial for anyone who is in rehab for a stress fracture. A case report published in 20123 examined the effectiveness of treating a pelvic stress injury with an anti-gravity treadmill. They used an injured female elite runner in need of rehabilitation as an example. The report showed that she was back to “pain‐free ground running at 8 weeks after running at 95% body weight on the antigravity treadmill.”
This is just one of many cases showing how the Boost Anti-Gravity Treadmill can enhance and accelerate different types of rehabilitation.

Types of Injuries Treated With an Anti-Gravity Treadmil

There’s a long list of conditions and injuries that can effectively be treated with the Boost Anti-Gravity Treadmill at MOTUS Specialists Physical Therapy. A workout targeted at weight loss can be augmented with the Boost treadmill, which allows overweight patients to run faster and longer without the same stress as in normal conditions.

The Boost treadmill is also used to treat post-surgery recovery, like knee or hip arthroplasty, and for conditions such as osteoarthritis, back pain, foot pain, and even balance issues. Shin splints, stress fractures, plantar fasciitis, and complex regional pain syndrome are other examples of the many injuries that can be treated with an anti-gravity treadmill.

Achilles surgery can be followed by a painful recovery, but in a 2011 study4, Amol Saxena and Allison Granot proved that “being able to run at 85% of body weight after Achilles surgery was sufficient to clear patients to run outside.”

Taking advantage of an anti-gravity treadmill can hasten recovery and help you return to normal after an injury or operation.
