System and method of motor task skill assessment

A method for performing sensorimotor or cognitive assessment or therapy of a patient, the method comprising, using a processor:

• parse a time-series of patient movements based on input signals from an input controller to produce a plurality of parsed movements;
• compute, for a plurality of target types, speed of the patient input for a set of parsed movements to the computer processor, and
• precision and variability of the patient input for the set of parsed movements;
• compute motor acuity based on the relationship between speed of the patient input and precision of the patient input, wherein computing motor acuity comprises creating a best-fit line in a comparison of speed of the patient input and variability of the patient input;
• and transforming the best-fit line to a curve in a comparison of patient speed and patient precision;
• and
• produce an assessment output that characterizes the patient's sensorimotor or cognitive fitness based on the motor acuity.

A method for performing sensorimotor or cognitive assessment or therapy of a patient, the method comprising, using a processor:

• computing, using the computer processor, for a plurality of target types, speed of the patient input based on input signals from an input controller to the computer processor, and one of precision and variability of the patient input based on input signals from the input controller to the computer processor;
• characterizing, using the computer processor, a change in motor acuity by performing a multiple linear regression of speed of the patient input and one of precision and variability of the patient input;
• and
• producing, using the computer processor, an assessment output that characterizes the patient's sensorimotor or cognitive fitness based on the motor acuity.
