Brief Summary
The research is towards an advanced control and computer learning strategy that will intelligently drive a powered walker for people with walking disabilities. The aim of the control strategy is to provide powered assistance that optimally reduces the metabolic cost of walking. The goal of the proposed intelligent walker is to reduce the workload of walking, keeping this population walking longer, providing critical exercise, continued muscle development and improved quality of life.

Outcome Measures
Primary Outcomes (1)
Metabolic Cost (Oxygen Consumption)
Oxygen consumption data will be collected with a Oxycon Mobile (VIASYS Healthcare Inc.) portable indirect calorimetry system. The outcome measure is the reduction in metabolic cost of using the powered walker compared to an unpowered walker.
Five minutes

SurePace Powered Walker User
EXPERIMENTALBefore any formal experiments are conducted, participants will be given an opportunity to "train" with the new powered walker for a pre-defined period of time to eliminate the confounding effects of being unfamiliar with using the device. (See the description of UVA's facilities and Protection of Human Subjects document for additional discussion of safety measures/protocols and Institutional Review Board procedures.) Experiments will consist of one-hour sessions (with adequate rest periods between trials and time for evaluations) in which participants will be asked to walk at a self-selected (comfortable) walking speed through a pre-defined 8 m x 4 m oval course.
Interventions
Participants will be asked to perform one baseline 5-minute trial with the lab's instrumented walker in passive mode (no powered locomotion) and two 5-minute trials with the walker in active mode (powered locomotion).
