Official title
Exoskeleton Footwear to Improve Walking Performance and Subject-reported Preference
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to determine the best assistance level of an exoskeleton footwear (EF) that can assist walking for people older than 40 with and without peripheral artery disease (PAD). The test will be performed on two different groups of people for this study that include: 1) people with PAD, and 2) individuals who don't have PAD. Data will be collected from 50 healthy older individuals and 25 patients with PAD, both groups will be 40 years or older. Gait biomechanics, muscle oxygenation, and energy cost for seven different walking conditions including normal walking, walking with EF with no assistance, and walking with EF with 5 different levels of assistance will be collected from the healthy older individuals. Additionally, subject-reported outcomes after each walking conditions including perceived comfort and fatigue, rate of perceived exertion and feasibility of the EF will be collected. Gait biomechanics, muscle oxygenation, energy cost, and patient-reported outcomes will be measured in patients with PAD for four walking conditions including normal walking, walking with EF but no assistance, walking with EF with the best two assistance levels. Subjects will be allowed to acclimate to the EF prior to recording data. All patients with PAD will participate in feasibility interviews that will assess acceptability, demand, implementation, and practicality. All subjects will be asked to fill out questionnaires that assess quality of life, physical function, and the ability to complete activities of daily living.
