Document Summary

Orienting: spatially uninformative cue - spatially informative cue. 48% of right hemisphere stroke patients have neglect. Severity of neglect predicted functional disability and family burden more accurately than did extent of brain damage. Told to focus on marking line on the left side of the page, helping them focus more on left hemisphere. It works for the task you"re working on, but generality is very poor. Multiple representations of space in different senses and in motor control. So if you change the sensory inputs to the areas that are damaged, we may be able to use that to help patients orient to area of space they neglect to orient to. Used only for persons who do not have hemiplegia. Told to passively or actively move contralateral arm in response to hearing a buzz. If left neglect, move left hand: active is when they"re asked to move it themselves. In passive and electrode on arm causes muscle stimulation to move hand.
