| Purdue Pegboard Test |
The Purdue Pegboard Test is a neuropsychological test of manual dexterity and bimanual coordination.The test involves two different abilities: gross movements of arms, hands, and fingers, and fine motor extremity, also called "fingerprint" dexterity.Poor Pegboard performance is a sign of deficits in complex, visually guided, or coordinated movements that are likely mediated by circuits involving the basal ganglia.

The pegboard consists of a board with two parallel rows with 25 holes into which cylindrical metal pegs are placed by the examinee. The test involves a total of four trials.[5] To begin, there is a brief practice. The subsets for preferred, non-preferred, and both hands require the patient to place the pins in the holes as quickly as possible, with the score being the number of pins placed in 30 seconds.
