Official title

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

Overview

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.

Detailed description

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

Primary outcome measures

  • Goal Attainment Scale (GAS) [Time frame: From enrollment to the end of treatment at 8 weeks]
Secondary outcome measures (5)
  • L-test and Dual-task L-test [Time frame: Initial visit, at 4 weeks, and at 8 weeks]
  • Two-minute walk test (2MWT) and 2MWT in divided attention [Time frame: Initial visit, at 4 weeks, and at 8 weeks]
  • Activity Balance Confidence Scale (ABC-scale) [Time frame: at 4 weeks, and at 8 weeks]
  • Prosthesis Evaluation Questionnaire (PEQ-A) [Time frame: at 4 weeks, and at 8 weeks]
  • Stumbles and falls [Time frame: at 4 weeks, and at 8 weeks]
