Evaluation of an articulated passive ankle–foot prosthesis

📑 Quick introduction to the System Usability Scale (SUS): It is a widely used questionnaire that measures the perceived usability of a system or product. It provides a simple and standardized way to assess user satisfaction. On the SUS, the average score is 68 out of 100, with higher scores indicating better usability.

🔬 Methodology: During the study, 42 participants were asked to perform a set of physical tasks with their current prosthesis and the Lunaris Demonstrator.

📊Our Results : On average, when asked to complete the SUS questionnaire, both above knee amputees and below knee amputee rated the Lunaris Demonstrator 82 out of 100 even only 2 hours familiarization time.

🔚 Conclusion : This score indicates that the device, despite no familiarization, is rated above average in terms of user convenience and that there is a high probability that participants will recommend the device to other peers.
