DEVELOPMENT STAGE

TRL-5 Prototype Validated in Relevant Environment: The prototype has been successfully tested in a simulated clinical setting.

BACKGROUND
Clinicians face challenges training dynamic balance in individuals with incomplete spinal cord injury. Current treadmill-based interventions do not adequately address lateral stability, leading to high fall rates and inefficient gait patterns. There is an unmet need for clinical tools that support precise, quantifiable balance training during walking.

ABSTRACT
The Agility Trainer 2.0 system applies adjustable, velocity-dependent lateral forces to a patient’s pelvis during treadmill walking. It uses motorized cable systems and high precision sensors to generate viscous force fields that either resist or amplify lateral movement. Preliminary case studies indicate significant improvements in dynamic balance and gait stability. This clinical tool offers a streamlined user interface for physical therapists and integrates easily with existing treadmill setups, paving the way toward production-ready deployment.

APPLICATIONS

  • Gait training for individuals with spinal cord injury: Enhances dynamic balance during treadmill walking.
  • Clinical rehabilitation tool for balance improvement: Supports systematic balance challenge.
  • Performance testing in gait laboratories: Quantifies lateral stability during walking.
  • Integration with standard treadmill training: Provides a customized, balance-challenging environment.

ADVANTAGES

  • Delivers quantifiable balance challenges: Allows precise adjustment of lateral force fields.
  • Improves gait stability: Helps reduce fall risk by targeting dynamic balance impairments.
  • Integrates with existing clinical equipment: Easily pairs with standard treadmills and supports.
  • Simplifies clinical operation: Features a user-friendly interface for single-operator use.
