Adaptive Hip Exoskeleton for Stroke Gait Enhancement
Sponsor:

Georgia Institute of Technology

Brief Summary:

This work will focus on new algorithms for robotic exoskeletons and testing these in human subject tests. Individuals who have previously had a stroke will walk while wearing a robotic exoskeleton on a specialized treadmill. The study will compare the performance of the advanced algorithm with not using the device to determine the clinical benefit.

Detailed Description:

The focus of this work is a proposed novel artificial intelligence (AI) system to self-adapt control policy in powered exoskeletons to aid deployment systems that personalize to individual patient gait. The investigators hypothesize that walking speed will improve with the use of the self-adaptive control policy system. Individuals post stroke have a broad range of mobility challenges including asymmetric gait, substantially decreased SSWS, and reduced stability, and therefore have greatly impaired overall mobility independence in the community. The investigators expect the proposed novel controller, capable of personalization to such variable and asymmetric gait patterns, will have significant benefits towards increasing community independence and mobility for patients post stroke. 12 patients post stroke will be fit with the hip exoskeleton and proceed to walk at varying speeds and inclines on a Motek CAREN system while the investigators measure self-selected walking speed. The self-adaptive system will be compared directly to a best-on-average control policy (non-adaptive) as well as to a 'standard of care' baseline. This baseline will be walking with no exoskeleton plus any clinically prescribed passive orthoses. The investigators expect the self-adaptive system to learn the control policy that best matches the patient's gait patterns, thus yielding advantages in walking speed.

Sexes Eligible for Study: ALL
Accepts Healthy Volunteers:
Criteria
Inclusion Criteria
  • * Between 18-85 years of age
  • * Had a stroke at least 6 months prior to study involvement
  • * Are community dwelling, which means the participant does not live in an assisted living facility
  • * Are able to provide informed consent to participate in the study activities
  • * Can safely participate in the study activities (per self-report)
  • * Must have a Functional Ambulation Category (FAC) score of 3 or above, which means the participant can walk without the assistance of another person
Exclusion Criteria
  • * Require a walker to walk independently
  • * Have a shuffling gait pattern
  • * Have a Functional Ambulation Category (FAC) score of 2 or lower, which means the participant requires the assistance of another person in order to walk
  • * Have a significant secondary deficit beyond stroke (e.g. amputation, legal blindness or other severe impairment or condition) that in the opinion of the Principal Investigator (PI), would likely affect the study outcome or confound the results
