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, the focus was on testing additional participants for both aims. Because of recruitment challenges in our local area, we conducted many of the tests at remote sites East Coast, Midwest at clinics we recruited as collaborators. Results from studies to date suggest that limb fluid volume changes over the course of the test sessions are larger pre-modification than post-modification, and that participants increase daily prosthesis wear and walk times post-modification compared with pre-modification. Individual participant reports are helpful towards characterization of how modifications affected limb fluid volume and user activity. Participant self-report scores appear to be slightly higher for the treatment than control group. Practitioners felt the data presentation improved understanding of their patients limb fluid volume management issues. Additional participants need to be tested for statistical comparisons to be made.
