Abstract

A Neurological Rehabilitation method utilizing oculomotor, visual and/or vestibular rehabilitation tasks on subjects with pharmacologically induced neuroplasticity comprising the steps of Inducing neuroplasticity in a subject through administering of a neuroplasticity medicament; Providing a oculomotor, visual and vestibular rehabilitation task platform configured to supply visual targets to a subject for oculomotor, visual and vestibular rehabilitation tasks and track and record eye movement of the subject during oculomotor, visual and vestibular rehabilitation tasks; Performing oculomotor, visual and/or vestibular rehabilitation tasks on the platform with subjects during periods of pharmacologically induced neuroplasticity. The neuroplasticity medicament generally is comprising at least one of an antidepressant, a Brain Derived Neuro trophic factor enhancer, a steroid, a psychedelic, valproic acid, NDRI's, lithium carbonate, Metformin, N-Acetylcystine, and Human Growth Hormone.

Claims (62)

1 . A neurological rehabilitation method for a stroke patient comprising the steps of

A) inducing neuroplasticity in a stroke patient through administering of a neuroplasticity medicament, wherein the neuroplasticity medicament comprises metformin;

B) providing a head mounted oculomotor, visual and vestibular rehabilitation task platform configured to supply visual targets on a head mounted display to the patient for oculomotor, visual and vestibular rehabilitation and track and record eye movement of the patient during oculomotor, visual and vestibular rehabilitation tasks, and to provide feedback to a clinician and the patient;

C) performing oculomotor, visual and/or vestibular rehabilitation tasks on the head mounted platform with the head mounted display with subjects during periods of pharmacologically induced neuroplasticity, wherein the tasks include a plurality of:

i) a subjective visual horizontal task in which the patient rotates a visible line shown on the head mounted display to position the line in a perceived horizontal position;

ii) a subjective visual vertical task in which the patient rotates a visible line shown on the head mounted display to position the line in a perceived vertical position;

iii) a gaze nystagmus task in which the patient focuses on a target location within the head mounted display and the platform obtains vertical, horizontal and torsional nystagmus measurements of each eye;

iv) a horizontal smooth pursuit task in which the patient is directed to follow a visible dot shown on the head mounted display as it moves through a horizontal sinusoidal displacement;

v) a vertical smooth pursuit task in which the patient is directed to follow a visible dot shown on the head mounted display as it moves through a vertical sinusoidal displacement;

vi) an optokinetic reflex testing task with visible stimuli shown moving on the head mounted display;

vii) a random horizontal saccade task in which the patient is directed to follow a visible dot shown on the head mounted display as it shifts suddenly from one position on the head mounted display to another horizontally shifted position on the head mounted display instantaneously;

viii) a random vertical saccade task in which the patient is directed to follow a visible dot shown on the head mounted display as it shifts suddenly from one position on the head mounted display to another vertically shifted position on the head mounted display instantaneously;

ix) a self-paced saccade task in which two stationary visible dots are presented on the head mounted display and the patient is instructed to generate as many saccades as possible between the two visible dots within a set time period;

x) a predictive saccade task in which patient is presented with a number of pseudo-random saccade stimuli on the head mounted display followed by saccade stimuli on the head mounted display with a repeated displacement and timing;

xi) a light reflex task in which the visible stimuli of varying brightness are presented to the patient on the head mounted display with the platform obtaining pupillary responses;

xii) a vergence task in which the patient is presented with a visible dot on the head mounted display virtually moving toward and away from the patient with the platform recording the vergence responses of the patient's eyes;

xiii) a memory guided sequence task in which the patient are then presented with a sequence of random peripheral temporary visible targets on the head mounted display and subsequently the patient is are directed to look at peripheral target locations on the head mounted display from memory;

xiv) a visual paired comparison task in which the patient is instructed to look at pairs of images presented consecutively on the head mounted display and to indicate when a repeated image appears;

XV) an anti-saccade task in which the patient is presented with a peripheral visible targets on the head mounted display and the patient is instructed to generate an eye movement in the opposite direction; and

xvi) a visual search task in which a field of target visible stimuli is presented on the head mounted display where at least one of those targets is different from majority of the remaining targets;

D) assessing the patient's performance of the tasks performed on the platform during periods of the subject's pharmacologically induced neuroplasticity; and

E) repeating steps A-D.

2 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the tasks include at least five of the tasks listed in C) i)-xvi).

3 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the tasks include at least the anti-saccade task.

4 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the tasks include at least the memory guided sequence task.

5 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the visual and/or vestibular rehabilitation or training tasks performed on the platform with subjects during periods of pharmacologically induced neuroplasticity which are repeated are modified based upon the assessment of prior performances.

6 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the tasks include at least ten of the tasks listed in C) i)-xvi).

7 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the tasks include at least the vergence task.

8 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the tasks include at least one of the subjective visual horizontal task and the subjective visual vertical task.

9 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the tasks include at least one of the horizontal smooth pursuit task and the vertical smooth pursuit task.

10 . The neurological rehabilitation method for a stroke patient according to claim 1 wherein the tasks include at least one of the random horizontal saccade task and the random vertical saccade task.

11 . A neurological rehabilitation method for a traumatic brain injury patient comprising the steps of

A) inducing neuroplasticity in a traumatic brain injury patient through administering of a neuroplasticity medicament, wherein the neuroplasticity medicament comprises metformin;
