Brief Summary:
An exoskeleton device is a robotic system designed to improve an individual's ability to move and perform tasks encountered in everyday situations. These devices consist of external rigid limb segments that assists humans through different body movements with the use of actuators. These devices are controlled by an onboard computer that determines the timing and magnitude of assistance deployed to the user. Exoskeleton controller performance is key to providing beneficial assistance that does not inhibit the user's movement. Preceding work will compare the benefit of personalized hip versus ankle joint exoskeleton assistance for improvement of post-stroke gait. It will combine exoskeleton technology with the user's movement feedback to improve wearable robotic assistance to an individual stroke survivor's gait pattern. For the clinical trial research covered under this protocol, the investigator will test various exoskeleton technologies with stroke survivors in real-world contexts, indoors and outdoors, and measure clinically meaningful outcomes and user perceptions regarding technology usability and adoption. The long-term goal is to deploy self-adaptive, adoptable exoskeletons for personalized assistance during community ambulation.
Detailed Description:
Participants will serve as their own control in this study. This study will be divided into 2 sessions that will occur on 2 separate days: 1) Hip Exoskeleton session and 2) Ankle Exoskeleton session. In each session, subjects will undergo two conditions in which they complete the outcomes measures 1) while wearing the exoskeleton and 2) in a baseline condition without the exoskeleton. Order of condition and session will be randomized.
Prior to the exoskeleton condition, subjects will be allowed time to acclimate to the device during a walking session on the treadmill. Subjects will proceed to complete a timed indoor community circuit in which they will complete a 10 meter walk test over an instrumented gait mat which will record information about their walking. The indoor community circuit may also include turning, walking up/down a ramp and walking up/down a staircase.
Subjects will then proceed to complete an outdoor 6-minute walk test (6MWT) on a pre-defined course on Georgia Tech's campus. When outdoors, participants will be guarded with a gait belt and a researcher who will walk alongside them throughout the experiment to reduce the risk for a fall. Borg Rating of Perceived Exertion (RPE) and Physiological Cost Index (PCI) will be assessed and calculated following completion of the 6MWT. Following each condition, subjects will then sit, rest and complete a suite of patient reported outcomes in which the investigators will ask questions about their perception of their performance with and without the device; investigators will also ask them questions about the device. Following completion of surveys, subjects will repeat the same outcomes for the other condition- either the baseline condition or the exoskeleton condition, depending on the initial randomization.
Throughout the procedures, subjects will be monitored for fatigue and asked if they need a break. They will be encouraged to voice any concerns (discomfort, fatigue or otherwise) to the research personnel, who will respond accordingly. Participants will be guarded with a gait belt or harness to reduce the risk of falls while participating in the protocol.
