Tapping rate

The tapping rate is a psychological test given to assess the integrity of the neuromuscular system and examine motor control. The finger tapping test has the advantage of being a relatively pure neurologically driven motor task because the inertial and intersegmental interactions are so small that biomechanical influences on movement are reduced.[1] Finger tapping involves three important features: time, spatial amplitude, and frequency.[2] Studies have reported that the average number of taps per 10-second interval can be used to distinguish between patients with mild traumatic brain injury and healthy controls,[3][4][5][6] is slower in people one month after sustaining a mild traumatic brain injury,[4] and in experienced boxers and soccer players who frequently "headed" the ball.[7] The speed of finger tapping has also been found to be related to severity of initial traumatic brain injury,[8] and can be used to help assess recovery from mild and moderate traumatic brain injuries.[4]
