Optimize Therapy with Stride Smart Gait Analytics

Stride Smart for AlterG® Anti-Gravity Treadmills® amplifies the power of precision unweighting therapy with real-time, intuitive, objective data assessment. By integrating gait analytics and pain recording with AlterG unweighting technology, Stride Smart enables you to harness key objective measures and optimize rehab in a wide variety of clinical applications. Easily, intelligently, and on the fly.

Stride Smart is integrated with built-in video monitoring.

Weight Bearing Symmetry Section

Improves balance control and reduces risk of pain and joint degeneration from overuse in the unaffected leg.

Step Length Symmetry

Improves symmetry for increased step length, better walking speed, more efficient gait, and reduced fall risk.

Stance Time Symmetry

Helps patients correct asymmetries to achieve increased step length, walking speed, and improved stance time.


Improvements can lead to faster gait, better mobility, and improved health.

Pain Recording

Correlating gait and unweighting with patient-reported pain scores helps establish optimal parameters for therapy.

Running, Injury, and Rehab on the Anti-Gravity Treadmill - AlterG

AlterG is proud to present this video showing a range of patients with different diagnoses using the AlterG:
1. A Parkinson's patient walking safely, allowing her to stay mobile and improve her condition
2. An overweight patient enjoying running for the first time and losing weight

AlterG is the game changer in physical therapy & rehabilitation.

Defy Gravity with the Anti-Gravity Treadmill.

The Alter G-Trainer offers personalized precision un-weighting benefits that build run specific endurance without the pain and risk associated with full-weight impact on joints, bones, tendons, and muscles. With a simple touch of a button, a runner can reduce bodyweight in 1% increments, all the way up to 80% of bodyweight.

How the AlterG Benefits a Senior Rehabilitation Patient

Meet Barbara. Barbara suffers from a spinal cord injury along with cervical stenosis. She currently uses a walker to assist in her mobility. Barbara exercises using AlterG's senior rehabilitation treadmill to work on balance, gait training, strength and endurance.
AlterG's Antigravity Treadmill is ideal for cardiac rehabilitation and physical therapy exercise.
