Metabolic Cost of Walking With Arm Swing Assistive Device
Conditions
Brief summary
This study aims to understand and compare the metabolic and mechanical demands placed on the body while walking normally and walking with the use of an apparatus that drives leg swing through the use of the arms. This information will help the investigators identify how arm swing mechanics helps minimize energy demands and to use this knowledge to design walking rehabilitation interventions in the future.
Interventions
The investigators are testing a simple, custom built apparatus to determine if it can facilitate the use of the arms to swing the legs during walking. More specifically, the investigators will measure how this assistive apparatus affects the metabolic cost and biomechanics of walking.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Metabolic Cost | Change from walking without assistive apparatus to walking with assistive apparatus. Measures of metabolic cost are completed within a 3-hour time window during a single laboratory visit. | Change in Metabolic Cost |
