An Adaptable Foot Prosthesis for People With Lower Extremity Amputations - Community Experiences

Detailed Summary

The purpose of the study is to obtain performance measurements and participant feedback about use of an investigational prosthetic foot compared to the participant's usual prosthetic foot. To accomplish this, the study will use a combination of laboratory motion analysis, functional tests, and community mobility trials where participants complete questionnaires and interviews about use of an investigational prosthetic foot compared to the participant's usual prosthetic foot. Individuals with amputations that participate in the (optional) motion analysis sub-study at the University of Washington will complete forward walking, side-step, and across river rock with usual foot (session 1), and also with the investigational foot locked and unlocked (session 2) after an accommodation period of between 1-4 weeks. The participants will rate their experiences using socket comfort score and the socket pressure score. Control participants recruited at the University of Washington to provide information about performance for people without amputation will go through the consenting process, then will be asked to complete forward walking, Figure-of-8 Walk Test, Narrowing Beam Walking Test, side-step, and walking across river rock surface. These tests will be conducted at a single session.
