An apparatus and method for rehabilitating patients and assessing tactile skills in response to visual stimuli generated from a portable neural training device. The device generates a visual output to elicit tactile response (hand movement) from the patient. The device preferably automatically adjusts the difficulty of a session in response to demonstrated patient skill level (i.e. combination of correct responses, speed, and accuracy of responses). The invention evaluates and challenges the patient to control tactile response, overcome visual perception difficulties, or practice simple multi-tasking or reasoning skills. The invention also provides information which is valuable to those administering the rehabilitation program or assessing patient skill and/or progress. By way of example the neural training device is described with an embodiment having discrete fixed keys and an embodiment utilizing a touch sensitive display screen.

What is claimed is: 1. An apparatus for assisting in the evaluation and rehabilitation of an individual having a neurological impairment, comprising: (a) a touch pad having a plurality of primary touch sensitive keys arranged in a matrix; (b) a secondary touch sensitive key positioned in the approximate center of each primary touch sensitive key; (c) a visual stimulus emitting source positioned in the approximate center of each said secondary touch sensitive key upon which user tactile response is to be directed; (d) a microprocessor and memory for storing executable programming; and (e) programming associated with said microprocessor for carrying out the operations of (i) providing visual stimuli to a user, (ii) monitoring position and timing of user tactile feedback in response to said visual stimuli, and lowering registered positional accuracy of tactile feedback in response to detecting user contact with the primary touch sensitive key when responding to the visual stimuli on said secondary touch-sensitive key, and from which incorrect tactile feedback is distinguished in response to detecting user contact outside of either the secondary or primary touch sensitive key, (iii) controlling presentation of said visual stimuli to the user and for processing said tactile feedback. 2. An apparatus as recited in claim 1, further comprising means for passively restraining a limb to restrict which limb user tactile feedback will be collected. 3. An apparatus as recited in claim 1, further comprising programming for carrying out the operations of: generating one or more patterns of visual stimuli; enabling one or more of said touch sensitive keys to be responsive to tactile feedback from the user in response to said visual stimuli; and altering the number and position of said touch sensitive keys which are responsive to tactile feedback from the user. 4. An apparatus as recited in claim 1, further comprising programming for supporting an administrator mode in which access is provided to performance statistics and for establishing device operating characteristics. 5. An apparatus as recited in claim 4, wherein said administrative mode programming is configured for providing access to said programming in said microprocessor for controlling operation of said apparatus. 6. An apparatus as recited in claim 1, further comprising programming for providing a responsive mode in which the user provides a tactile response to each visual stimuli. 7. An apparatus as recited in claim 6, wherein said responsive mode comprises: providing said visual stimuli; measuring response time and positional precision of the user's tactile feedback; and adjusting the number and position of said touch sensitive keys based on said response time and precision of user tactile feedback. 8. An apparatus as recited in claim 1, further comprising programming for providing a predictive mode in which response to the stimuli requires the user to extend a sequence. 9. An apparatus as recited in claim 8, wherein said predictive mode comprises: illuminating first and second adjacent touch sensitive keys, each said key having a light emitting source position in the approximate center thereof, wherein a said one of said light emitting sources is illuminated continuously, and wherein an adjacent said one of said light emitting sources is illuminated intermittently; receiving tactile feedback from the user in response to said illumination of said first and second adjacent touch sensitive keys; and providing audible feedback to the user if the user touches a touch sensitive key adjacent to said intermittently illuminated touch sensitive key. 10. An apparatus as recited in claim 1, further comprising programming for providing a visual perception mode in which multiple user inputs are required across a span of visual stimuli. 11. An apparatus as recited in claim 10, wherein said visual perception mode comprises: providing said visual stimuli; receiving said tactile feedback from the user; and providing a first type of audible feedback to the user in response to receiving said tactile feedback from the user; and providing a second type of audible feedback to the user in response to receiving said tactile feedback from the user; wherein said first type of audible feedback is provided in response to tactile feedback applied to individual touch keys; and wherein said second type of audible feedback is provided in response to tactile feedback applied to a predetermined number of said touch keys.
