Purpose
The Purdue Pegboard aids in the selection and rehabilitation of employees for various types of manual labor by measuring 2 types of dexterity:
- Gross movements of the fingers, hands and arms.
- Fine fingertip dexterity necessary in assembly tasks.

Diagnosis/Conditions
- Parkinson's Disease & Movement Disorders
- The Purdue Pegboard Test is a rectangular board with 2 sets of 25 holes running vertically and 4 concave cups at the top. Small metal pegs are placed in the cup on the side being tested, with subjects asked to remove the pegs and place them vertically in the holes as rapidly as possible. The number of pegs placed in 30 seconds is scored.
- The original application for the test was for testing the dexterity of industrial workers. It has since been used for testing of dexterity testing within various populations in the clinical setting, including children and adolescents.
- The test takes about 30 seconds per activity for a total of 5-10 minutes including instruction. The test administrator compiles 5 separate scores from the complete test procedure, one for each battery:
1) Right Hand (30 seconds)
2) Left Hand (30 seconds)
3) Both Hands (30 seconds)
4) Right+Left+Both Hands (This is not an actual test, but a mathematical sum calculation)
5) Assembly (60 seconds)

Professional Association Recommendation
Recommendations for use of the instrument from the Neurology Section of the American Physical Therapy Association’s Multiple Sclerosis Taskforce (MSEDGE), Parkinson’s Taskforce (PD EDGE), Spinal Cord Injury Taskforce (PD EDGE), Stroke Taskforce (StrokEDGE), Traumatic Brain Injury Taskforce (TBI EDGE), and Vestibular Taskforce (Vestibular EDGE) are listed below. These recommendations were developed by a panel of research and clinical experts using a modified Delphi process.

Considerations
Parkinson’s disease: Strong psychometrics. It is valid and reliable. It has been used in medication trials (Tan, 2003), post neurosurgery (Pal, 2000) and to measure dexterity during off times in PD (Brown, 1998). It was used to test dexterity during dual task performance (Proud, 2010). Correlated strongly to UPDRS total and motor (Proud, 2010). Dexterity decreases with increased severity of disease. Pegboard scores best correlated with bradykinesia and loss of dopamine per PET scan (Vingerhoets, 1997).
