Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a repeated measures prospective study and is no greater than a minimal risk study. All study procedures will be conducted at the Center for the Intrepid (CFI) through collaborative efforts of the Military Performance Lab at the CFI and the Sanders lab at the University of Washington. Data collected at the CFI will be coded, compiled, and shared with the University of Washington investigators.The objective of the research is to test if microprocessor-adjusting sockets improve Service member performance in Military specific activities compared to (a) user- operated, motor-driven adjustable sockets (i.e. sockets users adjust themselves), and (b) static (traditional) sockets. Investigators also test if microprocessor-adjusting sockets better maintain socket fit and limb fluid volume, and if self-reported outcomes are more favorable than for user-operated or static sockets. The hypotheses to be tested include: During intense Military specific tasks, compared to the user-adjusted socket and the static socket, the microprocessor-adjusting socket will: 1. minimize translational movement between the residual limb and the prosthetic socket; 2. maintain residual limb fluid volume; and 3. maximize prosthetic socket comfort. When using the microprocessor-adjusting socket compared to the user-adjusted socket and the static socket, participants will: 1. cover the greatest distance during a simulated combat patrol; 2. perform all high intensity Military specific tasks with less pain; 3. perform a simulated combat patrol nearer to uninjured levels of performance; and 4. rank usability at a level similar to the static socket. The specific aims are to: 1. Fabricate microprocessor-adjusting sockets specific for Service members and Veterans with goals of returning to high-level physical activities 2. Evaluate Military task performance in Service members with transtibial amputation using "Readiness Assessments," while wearing three socket configurations: microprocessor-adjusting, user-adjusting, and static * Simulated combat patrol in a Virtual Realty Environment * Military version of a Functional Capacity Evaluation 3. Characterize user preference and usability of different socket configurations
