Patent ID: 8425429

Claim:
A method of screening for a neurological disorder, comprising: (a) providing a portable, vibrotactile stimulation device comprising: (i) a plurality of stimulators for providing vibrotactile stimulation; (ii) stimulation drivers for driving the stimulators; and (iii) whereby the stimulators are independently controllable and operable for controlled stimulation of a subject with independently controllable stimulation parameters; (b) providing vibrotactile stimulation to the subject, wherein the vibrotactile stimulation comprises a standard independently controllable stimulation parameter and a test independently controllable stimulation parameter; (c) querying the subject for the subject's response to the standard and test stimulation parameters and recording and generating a tracking report based upon the response information; (d) repeating steps (b) and (c), wherein the test stimulation parameter is decreased for a correct subject response and increased for an incorrect subject response such that the subject's discrimination ability is determined; (e) repeating steps (b)-(d) in the presence of a modified independently controllable stimulation parameter that is provided to the subject such that the subject's discrimination ability is determined in the presence of the modified stimulation parameter; and (f) comparing the subject's discrimination ability in the presence and absence of the modified stimulation parameter, wherein a lack of a change in discrimination ability in the presence of the modified stimulation parameter indicates a neurological-disorder.
