About

Christina T. Fuentes has fundamentally advanced our understanding of how the brain perceives limb position—a process known as proprioception—and its critical role in movement control. Her work reveals that this internal sense is far from static; rather, it is remarkably dynamic and context-dependent. In her highly influential 2009 paper, "Where Is Your Arm? Variations in Proprioception Across Space and Tasks," which has garnered 239 citations, Fuentes demonstrated that the accuracy of arm proprioception varies significantly with changes in arm configuration and the specific task being performed. This foundational finding challenged long-held assumptions about a uniform sense of limb position, showing instead that the brain’s internal model of the body is constantly recalibrated based on spatial and task demands. By mapping these variations, Fuentes has provided a critical framework for understanding sensorimotor integration, with profound implications for rehabilitation robotics, prosthetic design, and therapies for neurological conditions that impair movement. Her work stands as a cornerstone in the field, reshaping how researchers and clinicians think about the body’s hidden sensory landscape.
