The finger-tapping test (FTT) is a neuropsychological test that examines motor functioning, specifically, motor speed and lateralized coordination. During administration, the subject's palm should be immobile and flat on the board, with fingers extended, and the index finder placed on the counting device. One hand at a time, subjects tap their index finger on the lever as quickly as possible within a 10-s time interval, in order to increase the number on the counting device with each tap. The original procedure calls for five consecutive trials within a 5-point range for each hand, but variations include a total of six trials, in two sets of three. Results from FFT can be compared to age and gender normative data and may indicate motor impairment or lateralized brain dysfunction. The FTT is included in the Halstead-Reitan neuropscyhological test battery.

The FTT may be included as part of a comprehensive...
