the Purdue Pegboard Test normative data for people aged 60 and over
Disability and Rehabilitation, 1995Co-Authors: Johanne Desrosiers, Rejean Hebert, Gina Bravo, Elisabeth DutilAbstract:Manual dexterity is frequently evaluated in rehabilitation services to estimate hand function. Several Tests have been developed for this purpose, including the Purdue Pegboard, which measures fine manual dexterity. The goals of the study were to verify the Test–reTest reliability with subjects aged 60 and over without upper limb impairment, and to develop normative data based on a random sample of healthy older community-living individuals. The results show that the Test–reTest reliability is good (intra-class correlation coefficients from 0·66 to 0·90, depending on the subTest). Norms are presented to help clinicians involved in rehabilitation services to better differentiate real dexterity deficits from those that may be attributed to normal ageing.

the Test reTest reliability and the minimal detectable change of the Purdue Pegboard Test in schizophrenia
Journal of the Formosan Medical Association, 2013Co-Authors: Chipang Lu, Wenshian Lu, Chinglin HsiehAbstract:Background/Purpose The Purdue Pegboard Test is widely used in measuring the hand dexterity of patients with schizophrenia. In patients with schizophrenia, the Test–reTest reliability and minimal detectable change (MDC) of this Test remain largely unknown, limiting the interpretability of this popular measure. The purpose of this study was to estimate the Test–reTest reliability and the MDC of the Purdue Pegboard Test for patients with schizophrenia. Methods A total of 147 patients with schizophrenia participated in this study. The participants were administrated the five subTests of the Purdue Pegboard Test, three trials in a row at both of the two sessions 1 week apart. The intraclass correlation coefficient (ICC) was used to examine the Test–reTest reliability and the MDC was calculated on the basis of standard error of measurement. Results The Test–reTest reliabilities of the five subTests were moderate to good (ICC = 0.73–0.88). The MDC (MDC%) was 3.0 (22.9%) for the dominant hand subTest, 3.1 (26.1%) for the nondominant hand subTest, 3.0 (31.7%) for the both hands subTest, 6.1 (17.7%) for the dominant + nondominant + both hands subTest, and 8.5 (35.3%) for the assembly subTest. Conclusion Our results reveal that the Purdue Pegboard Test has moderate-to-good Test–reTest reliability but substantial random measurement error. These findings should enable clinicians and researchers to monitor and interpret the changes in the hand dexterity of patients with schizophrenia more accurately and confidently.

the Purdue Pegboard Test normative data for older adults with low vision
Disability and Rehabilitation: Assistive Technology, 2017Co-Authors: Walter Wittich, Christina NadonAbstract:AbstractPurpose The usability of assistive technologies depends, in part, on the user’s ability to manipulate the device. In the context of aging and visual impairment, the visibility of any device and its components becomes crucial, and often users rely on tactile information in order to overcome visibility barriers. The purpose of this study was to establish performance norms for older adults with low vision on a common measure of manual dexterity: the Purdue Pegboard Test. Method The Purdue Pegboard was completed visually with the dominant, non-dominant and both hands by 134 older adults (age 60–97) with various levels of low vision, ranging from 20/30 to 20/604 in the better eye. Results Scores decreased significantly as age increased. In addition, performance using the dominant hand was generally best. Compared to previously published values, scores were lower than the norms for healthy older adults as well as those for younger visually impaired individuals. Conclusions The present values for older a...

validity and reliability of the Purdue Pegboard Test in carpal tunnel syndrome
Muscle & Nerve, 2011Co-Authors: Nasim Amirjani, Nigel L Ashworth, Jaret L Olson, Michael Morhart, Ming K ChanAbstract:There is a paucity of validated Tests to quantify hand function impairment due to carpal tunnel syndrome (CTS). The aim of this study was to Test the validity and reliability of the Purdue Pegboard Test (PPT) in CTS patients. We compared 190 CTS patients with 122 healthy, age-matched controls. CTS severity was determined based on electrophysiologic parameters and the Levine Self-Assessment Questionnaire. The time to complete the PPT and the Test–reTest reliability were Tested. The Test–reTest reliability was high with an intraclass correlation coefficient of 0.91. Compared to healthy controls, the CTS patients were significantly slower. Although the functional performance generally declined with increasing severity of electrophysiologic abnormalities, the correlation between hand function decline and symptom severity in the young and middle-aged groups was low. We conclude that the PPT is a valid and reliable tool to quantify functional impairment caused by CTS. It can be a useful outcome measure in young and middle-aged patients. Muscle Nerve , 2011

Differences in EMG Burst Patterns During Grasping Dexterity Tests and Activities of Daily Living.
Frontiers in Bioengineering and Biotechnology, 2018Co-Authors: Jennifer Rowson, Alaster Yoxall, Victor GonzalezAbstract:The aim of this study was to characterize the muscle activation patterns which underlie the performance of two commonly used grasping patterns and compare the characteristics of such patterns during dexterity Tests and activities of daily living. EMG of flexor digitorum and extensor digitorum were monitored from 6 healthy participants as they performed three tasks related to activities of daily living (picking up a coin, drinking from a cup, feeding with a spoon) and three dexterity Tests (Variable Dexterity Test-Precision, Variable Dexterity Test-Cylinder, Purdue Pegboard Test). A ten-camera motion capture system was used to simultaneously acquire kinematics of index and middle fingers. Spatiotemporal aspects of the EMG signals were analyzed and compared to metacarpophalangeal joint angle of index and middle fingers. The work has shown that a common rehabilitation Test such as the Purdue Pegboard Test is a poor representation of the muscle activation patterns for activities of daily living. EMG and joint angle patterns from the Variable Dexterity Tests which has been designed to more accurately reflect a range of ADl's were consistently comparable with tasks requiring precision and cylinder grip, reaffirming the importance of object size and shape when attempting to accurately assess hand function.

analyzing finger interdependencies during the Purdue Pegboard Test and comparative activities of daily living
Journal of Hand Therapy, 2017Co-Authors: Victor Gonzalez, Jennifer Rowson, Alaster YoxallAbstract:Abstract Study Design Bench and cross-sectional study. Introduction Information obtained from dexterity Tests is an important component of a comprehensive examination of the hand. Purpose of the Study To analyze and compare finger interdependencies during the performance of the Purdue Pegboard Test (PBT) and comparative daily tasks. Methods A method based on the optoelectronic kinematic analysis of the precision grip style and on the calculation of cross-correlation coefficients between relevant joint angles, which provided measures of the degree of finger coordination, was conducted on 10 healthy participants performing the PBT and 2 comparative daily living tasks. Results Daily tasks showed identifiable interdependencies patterns between the metacarpophalangeal joints of the fingers involved in the grip. Tasks related to activities of daily living resulted in significantly higher cross-correlation coefficients across subjects and movements during the formation and manipulation phases of the tasks (0.7-0.9), whereas the release stage produced significantly lower movement correlation values (0.3-0.7). Contrarily, the formation and manipulation stages of the PBT showed low finger correlation across most subjects (0.2-0.6), whereas the release stage resulted in the highest values for all relevant movements (0.65-0.9). Discussion Interdependencies patterns were consistent for the activities of daily living but differ from the patterns observed from the PBT. Conclusions The PBT does not compare well with the whole range of finger movements that account for hand performance during daily tasks. Level of evidence Not applicable.

Development of the Variable Dexterity Test: Construction, reliability and validity
International journal of therapy and rehabilitation, 2015Co-Authors: Victor Gonzalez, Jennifer Rowson, Alaster YoxallAbstract:Background/Aims: This article introduces a dexterity Test designed to assess individual types of dexterity used to carry out activities of daily living (ADL). The Variable Dexterity Test (VDT) was developed as part of a wider study, the broader aim being to fully understand dexterity and its effect on human-product interaction during ADL. This was done with a view to improve occupational therapy methods when assessing dexterity and general hand function. Methods: The control group consisted of 24 healthy participants. Estimates of reliability and validity were evaluated in this pilot study. Inter-rater and Test-reTest reliability were assessed using a one-way ANOVA. The validity of the Test was estimated by correlating participants' VDT scores with their proficiency to complete four ADL task actions and a standardised dexterity Test (Purdue Pegboard Test). Results: The Test produced consistent results among the control group with both a single assessor (Test-reTest reliability) and multiple assessors (int...

Results: The Test produced consistent results among the control group with both a single assessor (Test-reTest reliability) and multiple assessors (inter-rater reliability). High correlations between participants’ VDT scores and proficiency to perform ADL were found for most of the subTests. There was also a high correlation between participants’ scores from the Purdue Pegboard Test and the VDT. Conclusions: The VDT proved to be a flexible, reliable and valid tool that assesses dexterity based on ability to carry out ADL. Validity and reliability estimates show encouraging values, which recognises that the VDT can be used as an accurate method to assess more than one type of dexterity.
