What is the Purdue Pegboard Test?
The Purdue Pegboard Test is a specialized assessment designed to evaluate fine motor skills, hand dexterity, and coordination. The setup is simple yet highly effective: a rectangular board with two vertical rows of small holes, accompanied by a set of pegs, washers, and collars. The test measures how quickly and accurately an individual can place these components into the holes using one hand, both hands, or a combination of hands and fingers.
During the test, participants are instructed to insert as many pegs as possible into the holes within a set time limit. Some variations of the test include assembling washers and collars onto the pegs, adding an extra layer of complexity to further assess fine motor coordination.
This hand dexterity test is particularly effective because it isolates specific motor skills. For example, it evaluates unilateral hand function (using one hand at a time) as well as bilateral hand coordination (using both hands simultaneously). These measurements are crucial for understanding a patient’s motor abilities and identifying potential impairments.
The Purdue Pegboard Test is commonly used in occupational therapy, motor coordination evaluations, and neuropsychological testing. It is also a valuable tool in rehabilitation programs, allowing healthcare providers to monitor progress and adjust treatment plans as needed.

What Does the Purdue Pegboard Test Diagnose?
The Purdue Pegboard Test is a widely used diagnostic tool for evaluating fine motor skills, hand dexterity, and coordination. It plays a crucial role in identifying and monitoring various neurological, musculoskeletal, and motor function disorders. To understand its diagnostic value, it’s helpful to consider two key terms: positive predictive value (PPV) and negative predictive value (NPV). PPV refers to the likelihood that a positive test result accurately identifies the condition being tested for, while NPV reflects the likelihood that a negative result confirms the absence of the condition. These values, expressed as percentages, underscore the test’s accuracy. Below, we examine how the Purdue Pegboard Test aids in diagnosing specific conditions, supported by its predictive capabilities.
Parkinson’s Disease
Parkinson’s disease is a progressive neurological disorder that affects movement, often causing tremors, stiffness, and bradykinesia (slowness of movement). Fine motor skill impairments, such as difficulty with tasks requiring precise hand movements, are common in Parkinson’s disease. The Purdue Pegboard Test effectively identifies these deficits by measuring hand dexterity and coordination.
Patients with Parkinson’s often perform poorly on the test due to reduced motor control and tremors. Studies indicate a PPV of approximately 85% and an NPV of 90% for detecting motor impairments related to Parkinson’s disease using the Purdue Pegboard Test. This makes it a reliable tool for early diagnosis and for monitoring disease progression during treatment or therapy.
Multiple Sclerosis (MS)
Multiple sclerosis is an autoimmune disease that affects the central nervous system, leading to symptoms such as muscle weakness, spasticity, and coordination difficulties. Fine motor skills are frequently compromised in MS patients, particularly during flare-ups.
The Purdue Pegboard Test evaluates the extent of motor dysfunction by assessing hand-eye coordination and manual dexterity. Research shows a PPV of 82% and an NPV of 88% for detecting fine motor impairments in MS patients. Additionally, it helps occupational therapists design targeted interventions to improve hand function and enhance quality of life.
Stroke
A stroke occurs when blood flow to the brain is interrupted, potentially causing loss of motor function, speech difficulties, and cognitive impairments. Fine motor skill deficits, such as difficulty grasping objects or performing coordinated hand movements, are common among stroke survivors.
The Purdue Pegboard Test is frequently used in rehabilitation to measure recovery progress in hand function and dexterity. It provides objective data on a patient’s ability to perform both bilateral and unilateral tasks. The test’s PPV for identifying post-stroke motor impairments is approximately 87%, with an NPV of 89%, making it a valuable tool for both diagnosis and therapy planning.
