What this trial studies

This observational study aims to assess the impact of different prosthetic systems on the mental workload experienced by individuals with above-knee amputations. By utilizing a multicentric, national approach, the study will measure differences in mental workload in both laboratory settings and daily life. Participants will be required to use specific prosthetic devices and have the capability to set therapeutic goals. The findings will help to understand user feedback regarding the functionalities of new generation prostheses.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 18 to 84 with above-knee amputations who are using a compatible prosthetic knee and foot.

Not a fit: Patients who are bilateral amputees, hip disarticulated, or those who do not meet the eligibility criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prosthetic designs that reduce mental workload for amputees, enhancing their quality of life.

How similar studies have performed: While there have been studies focusing on the biomechanics of prosthetics, this specific approach to assessing mental workload is relatively novel.
