Preliminary Evaluation of a Diagnostic Tool for Prosthetics
Abstract
The purpose of this research is to integrate a novel limb fluid volume measurement instrument into clinical care, and then to evaluate its effectiveness to enhance prosthetic design and fitting. An observational cohort study and a randomized control trial are conducted. During this funding period, the focus was on recruitment of additional participants and test sites, and enhancement of the data processing and analysis techniques. Enhancement of recruitment efforts was modestly successful locally but not nationally. Data analysis conducted to date using limb fluid volume data collected during standing demonstrated variability and noise, possibly explaining the lack of statistical significance in study results to date. The analysis is now being conducted using stance phase minima during walking, which based from experience, should reduce variability and noise. The analysis variables have been expanded to include rate of limb fluid volume change during the AM 5-cycle test, PM 5-cycle test, intersession, as well as during each type of activity (walk, stand, sit). Relationships between these variables, self-report outcomes, field-measured activity, participant characteristics, and prosthetic componentry and design are being investigated.
