A momentum-enabled treadling methodology to improve gait and enhance mobility in patients with peripheral arterial disease.

University of North Carolina at Chapel Hill


Description

This is a pilot study of a new exercise device (TREDLR) designed to facilitate repetitive ankle flexion/extension movements (i.e., "treadling") through a momentum-driven internal flywheel while seated. The specific goals of this project are to understand the joint and muscle kinematic difference between treadling and conventional exercise, to explore improvements in mobility and exercise capacity in individuals who treadle compared to a control group, and to assess user affect and compliance with the device.
