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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 30 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Reducing Metabolic Cost of Walking by Exploiting Arm Swing to Drive Leg Swing
Estimated Study Start Date : October 1, 2018
Estimated Primary Completion Date : December 31, 2018
Estimated Study Completion Date : December 31, 2018

Arm Intervention/treatment
Experimental: Single Group Experimental
Each participant will act as their own control with variables of interest measured while walking without the assistive device and while walking with the assistive device.
Device: Arm Swing Driven Assistive Apparatus
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.

Primary Outcome Measures :
  1. Metabolic Cost [ Time Frame: 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
