Application of a Novel Wearable Vibrotactile Device for Individuals with Proprioception Deficiency: Linking changes in neurophysiology and motor behaviour

Our ability to sense where our limbs are in space can be lost as a result of injury to the nervous system. For example, when reaching for a glass many people who have had a stroke only know where their hand is by looking directly at it. The sense of limb position also becomes reduced with aging. When sense of limb position is limited then humans must move more slowly and carefully because our movements now require us to use visual feedback to know where our limb is in space. This project will measure the application of a wearable vibrotactile device with the goals of improving the sense of limb position to make moving easier. The effects of this novel wearable device will be assessed by measuring changes in brain activity and movement performance in healthy adults. The results of the experimental part of this project will provide the proof-of-concept basis for the partner organization to conduct clinical trials and market the novel device.
