At Evolve Physical Therapy, we always look for new and exciting ways to help our patients recover faster and feel better. One of the latest technologies in our Sherwood clinic is a microgravity treadmill. You may be wondering, “What is that?” I’ll explain!

What is a Boost Microgravity Treadmill?
A Boost microgravity treadmill is a unique device that helps people walk or run while reducing the impact on their bodies. It uses air pressure to lift the body slightly, making it feel lighter. This is very helpful for people recovering from injuries or with conditions that make walking or running painful.
Think of it like walking on the moon, where gravity is weaker. The treadmill makes you feel lighter, so your joints and muscles don’t have to work as hard. This can help people exercise without hurting themselves, even if they are still healing.
A microgravity treadmill reduces the impact of gravity on the user’s body. It uses air pressure to create a lifting force, allowing individuals to run or walk at a reduced percentage of their body weight. This results in microgravity treadmills being used more in healthcare and fitness facilities. Here’s a breakdown of how they work:
1. Differential Air Pressure (DAP) Technology:
- This is the core principle behind how these treadmills work. Dr. Robert Whalen originally developed it at NASA to help astronauts combat bone and muscle loss in space.
- The idea is to use air pressure to counteract the force of gravity. In space, this is done to simulate gravity. On Earth, it’s used to reduce the effects of gravity.
2. The Air Chamber:

- The Boost Treadmill has an air chamber (a bag or enclosure) surrounding the user’s lower body.
- This chamber is pressurized to a level higher than the air pressure outside.
3. The Lifting Force:
- The increased air pressure inside the chamber creates a lifting force to counteract gravity.
- Adjusting the air pressure allows users to experience a reduced percentage of their body weight.
4. Controlling the Experience:

- The Boost Treadmill allows users to adjust the percentage of their body weight they want to experience, typically in 1% increments.
- Adjusting body weight percentage allows for a safe and gradual progression in rehabilitation or training.
- Adjusting the speed of the treadmill is done by the knob control on the right or the touch screen.
In simple terms, imagine a balloon gently pushing you upwards as you walk or run. That’s what the microgravity treadmill does: it uses air pressure to lessen the load on your body.
How Does It Work?
The treadmill has a big air chamber surrounding it. You step onto the treadmill wearing specially designed shorts, filling the chamber with air. The air pressure pushes you up, so you feel less heavy on your feet. Depending on how much pressure is used, you can feel like you weigh 20% to 80% of your normal weight! This allows you to move more freely and comfortably without worrying about putting too much stress on your body.

The 5 Benefits of a Boost Microgravity Treadmill
The microgravity treadmill can help with many things, including:
- Less Joint Pain: Since you are lighter, there is less pressure on your joints, which can be great for people with knee, hip, or ankle pain.
- Faster Recovery: If you are recovering from an injury, using the treadmill allows you to start walking or running again without risking more damage. This can help you get back on your feet sooner.
- Better Balance: The treadmill helps you focus on walking and improve your balance without fear of falling. This is especially helpful for older adults or anyone who wants to strengthen their legs to improve balance.
- Increased Strength: While using the treadmill, you’re still moving your muscles, which helps you build strength. Since you’re walking or running without the full force of gravity, you can do more exercise without getting as tired or sore.
- Low-Impact Exercise: For people with osteoarthritis or chronic pain, the microgravity treadmill offers a way to get moving without stressing their bodies too much.
Who Can Benefit from a Boost Microgravity Treadmill?
Microgravity treadmills are used by many different kinds of patients, including:
- Athletes recovering from injuries: Whether they have a sprained ankle, a knee injury, or a stress fracture, they can use the treadmill to get back into their training without risking further harm.
- People with joint pain or arthritis: If your knees, hips, or back hurt when you walk, the treadmill can reduce the pain and help you exercise without discomfort.
- Post-surgery patients: After surgery, such as a knee or hip replacement, people need to rebuild strength and mobility. The microgravity treadmill makes it easier and safer to start walking and moving again.
- Older adults working on balance and strength: The treadmill is also great for older people who need to improve their balance and prevent falls.
- Anyone who wants to start exercising again after being inactive for a while: If you’ve been away from exercise, the treadmill can help you safely ease into a fitness routine.
