This study investigates how the movement of an amputated limb inside a prosthesis affects the health of the limb. The purpose is to understand the pressure changes within the prosthesis and their impact on limb health and function. An amputated limb refers to a limb that has been surgically removed, and a prosthesis is an artificial device used to replace the missing limb.

Participants will undergo assessments to measure the movement of their amputated limb within the prosthesis. The study will compare an adaptive vacuum system with standard prosthetic suspension methods like pin-locking or suction, to evaluate which method better supports limb health and function.

• Who can participate: Individuals who have had a unilateral transtibial or transfemoral amputation and are able to walk at a K2 level or higher are eligible. Participants must be at least 3 months post-amputation.
• Study details: Participants will be involved in assessments to evaluate how their limb moves within the prosthesis. The study will include comparisons between different prosthetic suspension methods, including an adaptive vacuum system that adjusts pressure for improved fit and comfort.
