Muscular dystrophy is a group of genetic diseases caused by mutations or abnormal genes that progressively results in weakness in or loss of muscle mass. Due to a degradation of the muscles, individuals have difficulties completing everyday tasks or pursuing hobbies such as trying to put on clothing or attempting to play a musical instrument.
Previous studies have shown that visual and somatosensory signals are required to estimate a user’s hand spatial locations in perspective to an area. Electrotactile stimulation can restore missing sensory responses in prosthetic subjects; however, it is still unclear how electrotactile stimulation affects proprioception of the finger in terms of direction and magnitude over a two-dimensional
The research makes definitive conclusions on how vibrotactile stimulation to the forefinger affects proprioceptive map error magnitude and direction. The data exhibits significant indications that vibrotactile stimulation to the forefinger increases human subjects’ ability to estimate their hand’s position in space without using visual cues compared to touching or hovering over the table in front
