Summary

This clinical investigation aims to evaluate a new articulated prosthetic foot during daily-life activities.

Detailed description

This clinical investigation aims to evaluate a new articulated prosthetic foot during daily-life activities. The primary objective of this clinical investigation is to evaluate the safety, effectiveness, and comfort of the new prosthetic foot, along with user satisfaction and its impact on quality of life during daily-life activities. The study aims to determine whether the prosthetic foot can be safely and effectively integrated into the users' routine mobility, while also providing a comfortable experience that enhances overall well-being. In addition to these primary outcomes, the study will address several secondary objectives to gain a more comprehensive understanding of the device's performance. These include assessing the biomechanical characteristics of walking with the new prosthetic foot, specifically focusing on gait parameters. The investigation also aims to evaluate the device's shock absorption capabilities and its ability to support multi-axial movement, both of which are important for natural and efficient locomotion. Furthermore, the study will explore the attentional demand required when walking with the new prosthetic foot, providing insight into how the device affects mental engagement during ambulation. Lastly, the influence of prosthetic alignment on performance and user experience will be examined to optimize fitting and functionality. Overall, the new prosthetic foot will be assessed during a variety of daily-life activities, with varying familiarization periods, allowing for a holistic evaluation of the prosthetic foot in realistic and diverse usage conditions.
