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 explore improvements in mobility and exercise capacity in individuals who treadle compared to a control group.

Change in Overground Walking Speed After Intervention
Measured from the time taken to walk 6 meters.
Time frame: Baseline, 6 weeks
Change in 6-min Walk Distance
Measured from the distance walked in 6 minutes.
Time frame: Baseline, 6 weeks
Change in Stride Length
Measured using motion capture as the distance between heel markers across successive steps.
Time frame: Baseline, 6 weeks
Change in Peak Ankle Power
Measured using motion capture and instrumented treadmill forces as the peak positive power generated by the calf muscles during the push-off phase of walking.
Time frame: Baseline, 6 weeks
