Assessing the Usability and Reliability of the Prototype Prosthesis Devices

"These 3 sessions will commence only upon successful completion of the prosthesis safety and reliability tests conducted in the preceding sessions.~For each module combination, a session will be conducted to assess motor performance through the acquisition of spatiotemporal parameters and energy efficiency parameters of gait. Motor performance will be evaluated using functional assessment tests and data will be recorded during the following activities:~* parallel bar walking on flat ground~* parallel bar walking on an inclined surface~* treadmill walking with a safety harness~* stair climbing/descending with a handrail~* standing up and sitting down from a chair within parallel bars At the end of each session, satisfaction questionnaires (ad hoc questionnaire) will be completed. At the end of the experiment, a usability scale for the devices (ad hoc System Usability Scale) will be completed.~Each session is expected to last approximately 2.5 hours."
