Arm && Interventions

Group	Intervention	Description
Balance assessment on specialized treadmill	Treadmetrix	Subjects will undergo a balance assessment on a microprocessor-controlled treadmill

Primary Outcome Measures

Name	Time	Method
Estimate the limits of agreement between observed and commanded treadmill belt disturbance parameters: average initial acceleration.	Duration of participant test session (approximately 2 hours)	Treadmill belt average initial acceleration (m/s/s) will be measured with a Motion Capture system for each perturbation trial and compared to the commanded magnitude to assess system accuracy.
Estimate the limits of agreement between observed and commanded treadmill belt disturbance parameters: peak velocity.	Duration of participant test session (approximately 2 hours)	Treadmill belt peak velocity (m/s) will be measured with a Motion Capture system for each perturbation trial and compared to the commanded magnitude to assess system accuracy.
Estimate the limits of agreement between observed and commanded treadmill belt disturbance parameters: belt displacement.	Duration of participant test session (approximately 2 hours)	Treadmill belt displacement (m) will be measured with a Motion Capture system for each perturbation trial and compared to the commanded magnitude to assess system accuracy.

Secondary Outcome Measures

Name	Time	Method
Kinetic loading exerted on treadmill during perturbations: treadmill force.	Duration of participant test session (approximately 2 hours)	Treadmill force (N) time series will be measured with force plates imbedded in the treadmill deck and recorded for each perturbation trial to assess the mechanical loading condition on the machine.
