Objective: Identify patterns of dynamic motor unit activity during functional opening and closing of the hand.

Development, Motor Learning and Rehabilitation
Patterns of Dynamic Motor Unit Activity


Characteristic patterns of coordinated activity across different phases of the drinking task highlight the neural control mechanisms that drive the firing behavior of motor units across different muscles to produce natural movements and activities of daily living.
