Determination of the optimal cutoff values and validity of the Purdue Pegboard Test

Abstract

Introduction The Purdue Pegboard Test (PPT) is crucial for assessing fine dexterity of patients with hand injury. Determining the PPT cutoff value is needed to distinguish patients with impaired hand dexterity from those with unimpaired hand dexterity. The aim of this article is to examine the construct validity of PPT and to determine its cutoff values for patients with hand injuries. Method The PPT and Disabilities of Arm Shoulder and Hand Questionnaire Turkish version (DASH-T) were used to measure hand dexterity. To examine construct validity, we measured the correlation between PPT and DASH-T. The cutoff values were determined using the receiver operating characteristic (ROC) curve generated with sensitivity and 1-specificity. We recruited 101 patients with hand injury and 162 healthy participants. Results Correlation between all subtests of PPT and DASH-T were weak ( r = −0.282; −0.473: p<0.05). The cutoff value for the assembly subtest of PPT was 24.5. The range of area under the curve (AUC) values for PPT subtests was good to excellent (AUC: 0.82–0.92). Conclusion The current study demonstrates that PPT is a valid instrument for measuring hand dexterity in patients with hand injury. Results also suggest that PPT distinguished the patients with impaired hand function from those with unimpaired hand dexterity.

A novel sensor-embedded holding device for monitoring upper extremity functions

“…The idea of creating a holding device was to provide a possible solution for the clinical issues in evaluating the hand and UE functions. These issues included 1) undigitized data ( Marvin, 2012 ; Chesworth et al, 2014 ; Kim et al, 2016 ), 2) subjective data collection ( Marvin, 2012 ), 3) removal of additional human labor ( Bohannon et al, 2006 ; Sigirtmac and Oksuz, 2022 ), 4) complicated newer technologies for most of the users ( Yusif et al, 2016 ), and 5) newer devices that were not focused on the force ( Tognetti et al, 2006 ; Lin et al, 2018 ).…”

“…The participants perform tasks within the designed period and clinicians calculate their performances based on how many pieces (pegs) are placed in the desired locations (holes) during the tasks. It is a performance-based outcome measure ( Sigirtmac and Oksuz, 2022 ). The normal range of the score can vary due to the different age groups and genders.…”

Transition to Labor Market among Young Adults with Serious Mental Illness

“…The PPT psychometric properties are well established, including test-retest reliability (0.37 < r < 0.82), construct validity (0.52 < r < 0.78), and internal consistency (0.41 < Cronbach α < 0.50) [31]. This is a widely used test in a range of health conditions, including mental health [32,33].…”

Network-level mechanisms underlying effects of transcranial direct current stimulation (tDCS) on visuomotor learning impairments in schizophrenia.

“…An advantage of the SRTT is that the underlying cortical circuitry has been extensively evaluated and is known to depend upon the interaction of components of the motor cortex and the prefrontal supplementary motor area (SMA) region (12,22,(34)(35)(36)(37)(38) with primary visual cortex (39) and the dorsal stream visual "action" system (40). Here, in order to interrelate SRTT performance to more traditional neurocognitive domains in Sz, we collected parallel data using both the MCCB and the Purdue Pegboard Test (41,42), which serves as a test of both procedural learning and motor dysfunction across neuropsychiatric disorders.…”
