About this trial

This is an interventional treatment trial for Peripheral Arterial Disease

Eligibility Criteria

65 Years - 99 Years (Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Be able to walk without an assistive aid (i.e., walker, cane)
  • Have the capacity the provide written informed consent
  • Have previously diagnosed peripheral arterial disease (by self-report)

Exclusion Criteria:

  • Lower extremity injury or fracture within the last 6 months
  • Have a leg prosthesis
  • Prisoners
  • Individuals clearly lacking the capacity to provide informed consent
  • Vestibular impairment

Sites / Locations

  • Applied Biomechanics Laboratory

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

No Intervention

Arm Label

Treadling Group

Control Group

Arm Description

Treadling subjects will do so 3x per week (15 min sessions) for 6 weeks.

Control Subjects continue their normal daily activities.

Outcomes

Primary Outcome Measures

Change in Overground Walking Speed After Intervention
Measured from the time taken to walk 6 meters.
Change in 6-min Walk Distance
Measured from the distance walked in 6 minutes.

Secondary Outcome Measures

Change in Stride Length
Measured using motion capture as the distance between heel markers across successive steps.
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.

5. Study Description

Brief Summary
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.
