A Powered Exoskeleton for Veterans With Knee OA

Description

The purpose of this study is to evaluate in-laboratory mobility outcomes, pain perception, and user satisfaction with the Keeogo , a robotic exoskeleton for providing assistance on knees during stand and swing for a population with impaired mobility, as compare with standard knee braces. The investigators hypothesize that participants could have improved performance outcomes on walk test, timed up and go test, stair test, pick up penny from floor test, and the Short Physical Performance Battery (SPPB) when using the Keeogo as compared with their prescribed knee braces.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * medical diagnosis of Grade 3 or 4 knee OA
  • * have a prescribed knee brace for at least three months
  • * self-reported knee pain when standing, walking, climbing stairs, squatting, or other mobility activities
  • * self-reported limitations to mobility and walking activities due to knee pain, stiffness, loss of range of motion
  • * neurological paralysis causing an inability to stand, weight bear or take stepping movements
  • * fixed contractures resulting in limited range of motion in the hip, knees, or ankles that prevent sitting, standing, walking, and/or squatting activities
  • * able to walk at a normal walking speed (\>1.2 m/s) based on a 6-minute walk test (6MWT)
  • * anthropometric incompatibility with the device
  • * any medical complication or co-morbidity as judged by the study physician to be contraindicated for wearing the device or walking (e.g., cardiovascular disorders, pressure ulcers, open wounds, lower limb vascular disorders, or other medical conditions)
  • * a score of \<8/10 on the MacArthur Competence Assessment Tool for Treatment (MacCAT-T) (as a proxy for cognitive competency screening); and 7) pregnancy or planning on becoming pregnant
