Clinical Study: The I-SUB socket confirms its value in improving user comfort

Comfort is an essential factor in the daily use of a prosthesis. For transfemoral amputees, the socket plays a central role: it provides the connection between the body and the prosthesis, while directly influencing mobility, posture, and quality of life.

With this in mind, a clinical study published in the scientific journal Prosthesis focused on the I-SUB sub-ischial socket, comparing it with an ischial containment socket, a design commonly used for transfemoral amputations.

This multicenter study, conducted in France with 25 transfemoral amputees, aimed to assess user-perceived comfort in various everyday situations, such as standing, walking, and sitting. Mobility was also analyzed to ensure that improved comfort did not come at the expense of functional capacity.

The results are encouraging: participants reported greater comfort with the I-SUB socket, particularly when sitting and standing. Mobility tests showed no significant difference between the two types of sockets. These findings suggest that the I-SUB can improve users’ day-to-day experience while preserving their mobility.

Another noteworthy result: at the end of the study, a large majority of participants chose to keep the I-SUB socket for daily use. This choice highlights the importance users place on comfort, freedom of movement, and how easily the prosthesis can be integrated into everyday life.

This publication further supports the growing interest in sub-ischial sockets and underlines the need to continue developing prosthetic solutions that are increasingly tailored to patients’ real-life needs.

Through this study, PROTEOR reaffirms its commitment to clinical innovation and to the continuous improvement of care for amputees.
