Brief description of study.

Researchers at Indiana University are currently enrolling participants in a research study to better understand the movement of amputated limbs and how the prosthesis impacts health.

Detailed description of study

The data will be used to develop a new type of prosthesis to control limb motion within the socket to improve limb health and functional performance.  This study will look at the movement of an amputated limb and how it affects pressure inside the prosthesis, evaluate the movement of the amputated limb inside the socket and how it affects overall health of the limb and will look at the effectiveness of an adaptive vacuum system compared to standard of care suspension prosthetics (pin-locking or suction).

Participants will be compensated for their participation.

Eligibility of study

You may be eligible for this study if you meet the following criteria:

  • Conditions: Unilateral transtibial amputee,Transfemoral amputee
  • Age: 18 years - 100 years
  • Gender: All

Inclusion Criteria

Unilateral transtibial or transfermoral amputee

Able to ambulate at a K2 level or higher

At least 3 months post-amputation

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.
