Enhancing Voluntary Motion in Broad Patient Populations With Modular Powered Orthoses

NCT05240014 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 33

Summary

The overall goal of this project is to develop modular, lower-limb, powered orthoses that fit to user-specific weakened joints and control force/torque in a manner that enhances voluntary motion in broad patient populations. This project aims to establish feasibility of assisting different populations with these modular powered orthoses. The investigators hypothesize that assisting lower-limb musculature with modular powered orthoses will improve 1) lifting/lowering posture in able-bodied subjects and 2) functional outcomes in elderly subjects.

Conditions

  • Lower-limb Orthoses
  • Frailty/Sarcopenia
  • Chronic Overuse Musculoskeletal Injuries

Interventions

DEVICE

Modular powered orthosis

This study will investigate modular, lower-limb, powered orthoses that fit to user-specific weakened joints and control force/torque in a manner that enhances voluntary motion in broad patient populations. The central hypothesis is that high-torque, low-inertia motor systems controlled with energetic objectives will enable modular powered orthoses to partially assist the joints. High-torque electric motors combined with minimal transmissions can be freely rotated (i.e., backdriven) by human joints, allowing the use of an emerging torque control method called energy shaping to reduce the perceived weight/inertia of the body during any motion. By mounting these modular actuators to commercial orthoses, this technology will be easily prescribed/configured by clinicians.
