Assessment of the Prosthetic System Impact on Mental Workload in Above-knee Lower Limb Amputees.

Evaluation of Medical Benefit of a New Prosthetic Leg Designed to Decrease Mental Workload in People With Lower Limb Amputation

New generation of lower limb prosthesis provide improved functionalities. They are usually studied in the scope of biomechanics, sometimes PROMs like quality of life. Following users feedback, it is desirable to better understand why and how mental workload is impacted by new technologies or features. This clinical investigation will try to measure a difference between different prosthetic systems, in lab and in daily life.

Multicentric, national, observational, prospective study, using AB type SCED.
