All you want to do is head to work, run errands, and take care of your family. But when pain makes it hard to walk, even these simple tasks can feel exhausting. Whether it’s from an injury or a condition like arthritis, pain can turn everyday movement into a struggle.
At Terry Physical Therapy, we understand your frustration. It’s one of many reasons we invested in an AlterG anti-gravity treadmill, a specialized tool that can help you get active while reducing stress on your joints and body. For many patients, it offers a safe way to move again.
Movement and Managing Pain: What You Need to Know
Movement is one of the most effective tools for reducing pain and improving function. Controlled, guided exercise improves mobility, reduces inflammation, and helps boost your body’s natural healing processes.
Furthermore, if you work long hours or spend time on your feet, staying mobile is critical for maintaining independence and productivity. It’s also why pain or injury can have such a devastating impact.
That’s where the AlterG treadmill comes in, as it provides a safe bridge between injury and normal activity, helping you to stay active as your body heals.

What Is the AlterG Treadmill?
If you think that an anti-gravity treadmill sounds like something from the space age, you aren’t exactly wrong! The AlterG actually was originally developed by NASA to train astronauts. However, it has plenty of Earth-side uses as well.
The AlterG uses air pressure technology to reduce your body weight by up to 80% while you walk or run on it. During use, you wear special shorts that zip into a sealed chamber around the treadmill. The machine then gently lifts part of the body weight using air pressure so you feel lighter and movement becomes easier and more comfortable.
How the AlterG Helps When Pain Makes Walking Hard
Pain often causes people to move less. Unfortunately, avoiding movement can lead to new problems, like weaker muscles or worse balance. As a result, movement becomes even more difficult.
The AlterG treadmill helps break that cycle by allowing people to move with less pain and less stress on injured areas. This is especially helpful for people dealing with issues like:
- Balance problems
- Knee arthritis
- Lower back pain caused by spinal strain
- Surgical recovery
- Work-related injuries
Four Benefits of Utilizing the AlterG Treadmill
1. Decreased Pain
Reducing body weight lowers the force going through the hips, knees, and ankles, allowing you to walk more comfortably and for longer periods. The longer you can walk (or even run), the more you can improve strength, stability, and cardiovascular endurance.
2. Return of Natural Walking Patterns
When someone is in pain, they often limp or shift their weight to one side, which can place stress on other joints. The AlterG makes it easier for you to practice normal walking mechanics, helping retrain the brain and muscles to walk with a proper gait. Restoring normal walking patterns prevents long-term compensation injuries.
3. Stronger Lower Body Muscles
Several muscles stabilize the body when you’re walking or running, including the hips, knees, and core. When these muscles are weak, pain can worsen. Reduced-weight walking with the AlterG can help you activate those stabilizing muscles, improve muscular endurance, and rebuild strength without overloading your body.
4. Enhanced Recovery after Surgery
After procedures such as knee replacement or ligament repair, walking can be painful early in recovery, but movement remains important for good outcomes. That’s why it’s important to gradually increase weight-bearing activities during healing. Because the AlterG treadmill lets us control how much weight you’re bearing on your joints, you can gradually and safely increase your activity levels after a surgical procedure.

Let’s Get You Back to the Activities You Enjoy
Pain shouldn’t stop you from doing the things that matter most. Whether your goal is returning to work, walking comfortably, or staying active with family, the right therapy tools can make recovery easier.
The AlterG treadmill at Terry Physical Therapy is one of those tools. And with the guidance of our physical therapists, it can help restore movement and improve daily life.
