Method and interpretation
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.{{cite book|author1=Patricia Espe-Pfeifer|author2=Jana Wachsler-Felder|title=Neuropsychological Interpretations of Objective Psychological Tests|url=https://books.google.com/books?id=7O66Q2-Oa9gC&pg=PA26|accessdate=19 August 2013|date=30 April 2000|publisher=Springer|isbn=978-0-306-46224-5|pages=26–}} 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.
