VR study reveals how limb disuse warps your sense of reach

This study uses virtual reality to explore how people with upper limb exclusion (non-use of an arm or hand) perceive the space around them. Researchers will compare 60 participants—those with the condition and healthy controls—as they judge whether virtual objects are reachable. The goal is to understand if the brain's map of reachable space shrinks due to limb disuse.
