Overview

The purpose of this study is to evaluate the performance and adaptability of a neural-controlled powered knee or ankle prosthesis across diverse real-world mobility tasks. This research aims to assess how compare the sense of embodiment with the device, symmetry, and stability of a person with an lower-extremity amputation walking with a bionic prosthesis and their prescribed prosthesis. Findings from this study will inform future developments in bionic prosthesis design with optimal integration with the human body, with the goal of improving prosthetic integration into daily life.

Eligibility

Inclusion Criteria:

• Male or Female age 18-70.
• The patient must have a unilateral transfemoral amputation .
• The patient must have the ability to ambulate at variable cadence (an expected lower extremity prosthesis functional level of K3 or above).
• The patient must have adequate socket to support the device.

Exclusion Criteria:

• Women who are pregnant.
• Severe co morbidity, atypical skeletal anatomy, or poor general physical/mental health that, in the opinion of the Investigator, will not allow the subject to be a good study candidate (i.e. other disease processes, mental capacity, substance abuse, shortened life expectancy, vulnerable patient population, BMI >40, etc.).
