Recovering from an injury, surgery, joint pain, or mobility issue can make even simple movement feel difficult. Walking may hurt. Running may feel out of reach. Returning to activity may feel frustratingly slow.
That is where the AlterG Anti-Gravity Treadmill can help.
Available at select CORA Physical Therapy clinics, the AlterG Anti-Gravity Treadmill uses advanced unweighting technology to reduce the impact of body weight while you walk, jog, or run. This allows many patients to move with less stress on their joints, practice proper gait mechanics, and build strength and confidence in a safer, more controlled environment.
Whether you are recovering from surgery, managing pain, rebuilding endurance, or trying to return to sport, the AlterG may be part of a personalized physical therapy plan designed around your goals.
What Is the AlterG Anti-Gravity Treadmill?
The AlterG Anti-Gravity Treadmill is a specialized treadmill used in physical therapy, rehabilitation, and sports performance. Unlike a standard treadmill, the AlterG uses differential air pressure technology to gently lift and support the body while the patient walks or runs.
During a session, the patient wears specialized shorts that zip into the treadmill’s air chamber. Once the system is calibrated, the chamber fills with air and allows the clinician to reduce the amount of body weight placed through the legs.
In simple terms, the AlterG helps you move while feeling lighter.
For some patients, this can make it possible to walk, jog, or practice movement patterns that may be too painful, difficult, or unsafe on a traditional treadmill or on the ground.
How Does the AlterG Treadmill Work?
The AlterG allows your physical therapist to adjust how much body weight you feel while moving. Depending on your condition, goals, and stage of recovery, your therapist may reduce the load on your body so you can exercise with less pressure through your hips, knees, ankles, feet, or spine.
This controlled support can help patients:
- Walk with less pain
- Practice proper balance and gait
- Begin weight-bearing activity earlier in recovery when appropriate
- Improve endurance with less joint stress
- Build confidence after injury or surgery
- Return to running or sport in a gradual, structured way
Because the AlterG provides a controlled environment, your therapist can adjust speed, incline, and body-weight support throughout your session based on your progress and comfort level.

Benefits of the AlterG Anti-Gravity Treadmill
The AlterG Anti-Gravity Treadmill can be helpful for a wide range of patients, from athletes returning to sport to older adults working to improve mobility and confidence.
Reduced Impact on Joints
One of the biggest benefits of the AlterG is the ability to reduce the amount of weight placed on the lower body. This can be especially helpful for patients dealing with pain, arthritis, post-surgical precautions, or lower-extremity injuries.
By reducing impact, patients may be able to move more comfortably while still working on strength, endurance, and walking mechanics.
Safer Gait and Balance Training
For patients relearning how to walk properly, the AlterG provides a supportive environment for gait training. This can help patients focus on step length, posture, stride, and balance without placing full body weight through the legs right away.
This can be useful after surgery, injury, neurological conditions, or periods of limited activity.
Earlier Return to Movement
When clinically appropriate, the AlterG may allow patients to begin walking or running activity sooner than they could on a traditional treadmill or hard surface. This can help reduce fear of movement, maintain conditioning, and support a gradual return to daily activities.
Your CORA physical therapist will determine when and how the AlterG fits into your recovery plan.
Helpful for Athletes and Runners
For runners and athletes, the AlterG can provide a way to maintain conditioning while reducing stress on the body. It may be used as part of recovery from overuse injuries, stress-related pain, or return-to-running programs.
Instead of stopping activity completely, some patients may be able to continue training at a reduced body-weight load under the guidance of a physical therapist.
A More Comfortable Exercise Experience
Pain, fatigue, and mobility limitations can make exercise feel intimidating. The AlterG can help make movement feel more manageable by reducing the load on the body and allowing patients to exercise in a controlled setting.
At CORA, patients are guided by licensed physical therapy professionals who understand their condition, recovery timeline, and goals.
What Conditions Can the AlterG Treadmill Help With?
The AlterG Anti-Gravity Treadmill may be used as part of a physical therapy plan for many injuries and conditions, including:
- Achilles tendinitis
- Ankle, foot, hip, or knee injuries
- Balance and gait issues
- General weakness or deconditioning
- Joint pain
- Low back pain
- Osteoarthritis
- Plantar fasciitis
- Post-surgical recovery
- Running-related injuries
- Shin splints
- Stress fractures
- Total knee or hip replacement recovery
- Weight-bearing progression after injury or surgery
Not every patient or condition is appropriate for AlterG training. Your physical therapist will evaluate your needs and determine whether it is a good fit for your care plan.
Is the AlterG Treadmill Like Aquatic Therapy?
The AlterG Anti-Gravity Treadmill and aquatic therapy both reduce the amount of weight placed on the body during movement. However, they work differently.
Aquatic therapy uses the buoyancy of water to reduce impact. The AlterG uses air pressure to reduce body-weight load while allowing patients to walk or run on a treadmill surface. This means patients can practice walking and running mechanics in a way that may feel more similar to land-based movement.
For some patients, the AlterG may be a helpful alternative when aquatic therapy is not available, preferred, or appropriate.
What to Expect During an AlterG Session
During your first AlterG session, your physical therapist will explain how the treadmill works and help you get set up. You will wear specialized shorts that zip into the treadmill chamber. Once you are secured, the system calibrates to your body and your therapist adjusts the amount of support.
From there, your therapist may guide you through walking, jogging, running, balance work, or other movement exercises depending on your plan of care.
Most importantly, your session will be based on your comfort, safety, and recovery goals.
