1. A response measuring system for measuring the time required for a user to respond to an event, comprising:
- a computer;
a display screen;
a seat;
a steering device;
a start button for starting a diagnostic process, wherein actuation of the start button initiates the display of a first instruction to a user to perform a first driving-related cognitive task;
an end button for terminating the diagnostic process;
one or more foot pedals;
a plurality of sensor input receivers associated with the steering device and the one or more foot pedals for sensing a change in position of the steering device and one or more foot pedals; and
a computer readable medium comprising instructions to cause the display of a display scenario on the display screen, the display scenario comprising annunciator outputs;
a first timer configured to measure a first elapsed time between actuation of the start button and initiation of a change in position of the steering device or a foot pedal indicative of completion of the first cognitive task;
a second timer configured to measure a second elapsed time between completion of the first cognitive task and completion of a first physical task comprised of movement of the steering device or a foot pedal from a first, predetermined position to a second predetermined position, wherein the second controller timer begins measuring time upon completion of the first cognitive task;
a third timer configured to measure a third elapsed time between completion of the first physical task and actuation of the end button, wherein the third controller timer begins measuring time upon completion of the first physical task; and
a memory device to store at least one of the elapsed times.

7. A reflex response device for diagnosing a neurological and/or musculoskeletal disease or disorder comprising:
-
a controller comprising; a plurality of annunciator driving outputs; a plurality of sensor input receivers; first, second and third timers responsive to at least one of the said annunciator driving outputs and the sensor input receivers; and a memory responsive to said sensor input receivers; a start button for starting a diagnostic process, wherein actuation of the start button initiates the display of a first instruction to a user to perform a first cognitive task; an end button for terminating the diagnostic process; a plurality of annunciators responsive to said controller annunciator driving outputs; a plurality of sensors, each individually connected to a plurality of sensor input signal generators each generating a sensor input signal transmitted to said plurality sensor of input receivers; wherein each of the plurality of annunciators are positioned to be perceivable by the user and wherein each of the sensors are operable by the user; said first controller timer being configured to measure a first elapsed time between actuation of the start button and generation of a corresponding input from a first sensor indicative of completion of the first cognitive task; said second controller timer being configured to measure a second elapsed time between completion of the first cognitive task and completion of a first physical task, wherein the second controller timer begins measuring time upon completion of the first cognitive task; said third controller timer being configured to measure a third elapsed time between completion of the first physical task and actuation of the end button, wherein the third controller timer begins measuring time upon completion of the first physical task; wherein the memory is configured to store the first, second and third elapsed times; a database comprising user specific information; and a computer program on computer readable medium comprising instructions to cause the computer to acquire an elapsed time and to associate the elapsed time with the user specific information to diagnose a neurological and/or a musculoskeletal disease or disorder based upon the elapsed lime. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
