  • a golf club is selected, a ball is placed on the ground and the pre-motor and motor cortexes become very involved in attempting and (finally, after many, many balls have been struck) mastering the swing to a level where it is very repeatable.
  • the motor movements involved are transferred to the subconscious cerebellum for execution each time a golf swing is performed.
  • the swing is repeatable but may not be very effective for hitting the ball straight, or as far or as high as desired, etc.
  • a device and method are provided for substantially real-time cognitive training of a user to improve their ability to perform complex athletic movements, such as may for example be involved in a golf swing, football pass, baseball throw, and the like.
  • a plurality of sensing modules are each effective to detect movement of associated body parts of the user and to generate an output signal representative of the detected movement.
  • a controller is linked to each of the sensing modules so as to receive the output signals from the plurality of sensing modules and is further configured to detect movement combinations of the plurality of output signals, compare the detected movement combinations with a predetermined one or more expected movement combinations associated with a complex athletic movement, and generate an output signal such as an audible signal or a buzz to the user in substantially real time based on the comparison and a predetermined output mode.
  • the controller may be configured to compare a sequence of detected movement combinations with a predetermined sequence of expected movement combinations, to generate a first output logic state for each detected movement combination in the sequence that satisfies an associated expected movement combination, and to generate a second output logic state for each detected movement combination in the sequence that fails to satisfy an associated expected movement combination.
  • the predetermined output mode may include commands to generate an output signal for either of the first or second output logic state in association with any one or more of the expected movement combinations.

  • Another important principle with regards to the present invention is that post facto feedback correction of errors with respect to complex motor movements does not effectively cause the cerebellum to assume control of the movements.
  • a feed-forward control proactively addresses conditions that may be anticipated rather than relying on delayed feedback and provides guidance based on learned behavior.
  • the cerebellum therefore may effectively guide movements that take place far too quickly to benefit from post facto feedback (i.e., a golf swing).

Likewise, the controller may generate (in step 520) a second output state where the detected movement combinations are in accordance with the expected movement combinations and any associated tolerances or other parameters (i.e., "YES" in response to the query in step 516).
