The purpose of this research is to integrate a novel limb fluid volume measurement instrument into clinical prosthetics, 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, strategies were created and implemented to test the instrument on trans-tibial prosthesis users at remote locations. A novel system developed to monitor user activities walking, standing, sitting, and doffing in participants free living environments for 2 to 4 weeks proved effective, and helped to characterize impact of socket modificationreplacement on patient-centered outcomes. In general, socket modificationreplacement slightly enhanced walking and standing activities, and enhanced limb fluid volume gains during walking. Limb fluid volume changes during resting were mixed. Self-reported outcomes generally improved with socket modificationreplacement. A next step is to analyze collected data to address study hypotheses, and to extend participant recruitment and data collection to other remote facilities.
