Title : Prosthesis embodiment of the lower extremity: A narrative review
Abstract:
Prosthesis embodiment refers to the integration of a prosthetic device into an individual’s sense of self, extending beyond its function as an assistive tool. While extensively studied in upper limb prosthetics, embodiment in lower limb prostheses remains less explored. This poster examines the concept of prosthesis embodiment in individuals with lower extremity limb loss, including the psychological and physiological factors that contribute to increased embodiment. We will review current methodologies used to assess embodiment in lower limb prostheses and discuss the impact of sensory feedback, mobility, and user experience on improving prosthetic integration and functional outcomes. Additionally, we will explore advancements in neuroprosthetic interfaces, including TIME (Transverse Intrafascicular Multichannel Electrode) and C-FINE (Composite Flat Interface Nerve Electrode) nerve interfaces, and rehabilitation strategies that enhance sensory perception, proprioception, and user confidence. We outline how these approaches contribute to improved proprioception, reduced phantom limb pain, and a decreased perceived prosthesis weight, leading to greater mobility and patient satisfaction. A better understanding of these factors can inform future prosthetic design, guide clinical practice, and shape rehabilitation protocols, ultimately improving patient care and quality of life for individuals with lower limb amputations.
