Abstract

Described are methods, systems, and mediums for testing neuromechanical and neurocognitive function which reflect physical and mental compromise that may be associated with, for example, traumatic brain injury (TBI). In particular, a computer-executed method, system, and computer readable medium for testing neuromechanical and neurocognitive function of a subject are described which measure a subject'"'"'s performance in a test comprising one or more test modules designed to challenge neuromechanical and neurocognitive function and compare the performance to one or more baselines to evaluate physical and mental compromise.

Claims

1. A computer-executed method for testing neuromechanical and neurocognitive function in a subject comprising:

rendering a test comprising at least one test module for displaying the test to the subject;

generating a request for subject input indicative of the subject'"'"'s response to the displayed test;

receiving the subject input indicative of the subject'"'"'s response to the test;

computing at least one subject score as a function of the received subject input;

comparing the at least one subject score to at least one baseline comprising a subject baseline, wherein the subject baseline comprises a mean score and a standard deviation computed from a plurality of scores obtained from previously completed tests by the subject; and

providing the at least one subject score and providing the score comparison for displaying to the subject.

2. The method of claim 1 wherein the test comprises two or more test modules and wherein the method comprises:

computing at least one module score, at least one dimension score, and at least one total score as a function of the received subject input;

comparing the at least one module score, at least one dimension score, and at least one total score to at least one baseline; and

providing the computed scores and the score comparison for displaying to the subject.

3. The method of claim 1 wherein comparing the at least one subject score comprises computing the number of baseline standard deviations the score falls from the baseline mean score (standard deviation offset).

4. The method of claim 1 wherein the subject baseline is selected from the group consisting of a subject'"'"'s recent baseline, a subject'"'"'s extended baseline, a subject'"'"'s composite baseline, and combinations thereof.

5. The method of claim 1, wherein the subject baseline is generated by computing a mean score and standard deviation from a plurality of scores obtained from at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, or at least 15 previously completed tests by the subject.

6. The method of claim 1 wherein the at least one subject score is compared to a population baseline.

8. The method of claim 6 wherein the at least one subject score is compared to a subject'"'"'s recent baseline, a subject'"'"'s extended baseline, and a relevant population baseline.

14. The method of claim 1 further comprising applying a statistical process control method to one or more subject score comparisons;

generating an indication of subject impairment or improvement based on the applying; and

providing for display to the subject the generated indication.

15. The method of claim 14 wherein applying a statistical process control method comprises applying one or more approaches comprising:

(1) determining whether a single score (module score, composite score, and/or total score) is three or more standard deviations from the mean score,

(2) determining whether two out of three consecutive scores (corresponding module scores, composite scores and/or total scores) obtained from three or more of the subject'"'"'s tests are two or more standard deviations from the mean score on the same side,

(3) determining whether four out of five consecutive scores (e.g., corresponding module score(s), composite score(s), and/or total score(s)) obtained from five or more of the subject'"'"'s tests are more than one standard deviation from the mean score on the same side,

(4) determining whether nine consecutive scores (e.g., corresponding module score(s), composite score(s), and/or total score(s)) obtained from nine or more of a subject'"'"'s tests are on the same side of the mean score,

(5) determining whether six consecutive scores (e.g., corresponding module score(s), composite score(s), and/or total score(s)) obtained from the subject'"'"'s six consecutive tests all are increasing or decreasing,

(6) determining whether six consecutive scores (scores relating to the same module score, composite score, and/or total score) obtained from the subject'"'"'s six consecutive tests indicate a consistent mixed pattern of relatively extreme high and low values by falling more than one standard deviation from the mean score on both sides,

(7) determining whether nine consecutive scores (scores relating to the same module score, composite score, and/or total score) obtained from the subject'"'"'s nine consecutive tests indicate a consistent alternating trend (e.g., scores alternating up and down), and/or

(8) determining whether 15 consecutives scores (scores relating to the same module score, composite score, and/or total score) obtained from the subject'"'"'s 15 consecutive tests indicate a trend of increased performance consistency by falling between plus one and minus one standard deviations from the mean score.

16. The method of claim 1 wherein the test comprises at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 20 or at least 25 test modules.

18. The method of claim 16 wherein the test comprises at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 15, at least 20 or at least 25 test modules that challenge eye movement.

20. The method of claim 1 wherein the test comprises at least one test module for displaying to the subject selected from the group consisting of an interceptor test module, an avoidance test module, a track test module, and combinations thereof.

28. The method of claim 1 wherein subject input is received by an input device selected from the group consisting of a computer mouse, keyboard, touch-screen, touch-pad, joystick including an isometric joystick, remote control, a gaming controller, a motion sensing input device and combinations thereof.

29. The method of claim 1 wherein the test is displayed to the subject on an electronic viewing device selected from the group consisting of a computer monitor, touch-screen, television, electronic tablet device, hand-held gaming device, and wireless phone.

30. The method of claim 1 wherein the computer-executed method is for testing neuromechanical and neurocognitive function which reflects physical and mental compromise associated with traumatic brain injury and other closed cranial injury in a subject.

31. The method of claim 1 wherein the computer-executed method is for testing neuromechanical and neurocognitive function which reflects physical and mental compromise associated with impairment to brain function caused by substance use or abuse, diseases including nervous system diseases, disorders which alter brain activity, psychiatric disorders, conditions which impact brain function, or accidental or naturally-occurring events which impact brain function.

32. The method of claim 1 wherein the computer-executed method is for testing neuromechanical and neurocognitive function which reflects the physical and mental readiness of a subject prior to, during, and/or subsequent to engaging in the subject'"'"'s occupation.

33. The method of claim 1 further comprising:

generating a request for subject-specific information from the subject;

receiving the subject-specific information;

rendering a test comprising at least one test module based on the subject-specific information received for displaying to the subject;
