neurocognitive and fine motor deficit in asymptomatic adolescents during the subacute period after concussion [6, 7]. The Grooved Pegboard Test was also used to assess the fine dexterity after virtual reality (VR) immersion and cyber-sickness for 89 participants aged between 19 and 36 years [8]. In addition, the GPT was used to assess the hand dexterity for various diseases [9, 10, 11, 12]. Although the FPT, PPT, and NHPT all have the same testing principle in examining hand dexterity, they differ in the number and the arrangement of the board configuration, as shown in Figure 1. They also proved to be efficient in different diseases. The GPT has 25 holes, which are arranged as five rows by five columns, and has been used for the post-brain surgery and for the possibility of assessing the lateral brain damage [13, 14, 15]. The study by [PERSON] et al. has shown that the GPT is not efficient when used with very young or very old adults and with patients in the early stage of neurological diseases [16]. In contrast, the PPT has two sets of 25 holes arranged as right and left columns. The PPT has been used extensively to aid in the selection of employees for jobs that require fine motor dexterity and coordination, such as assembly work settings and industrial factories. Further, this test has been used with patients affected by the Parkinson, Multiple Sclerosis, Stroke, and other patients with neurological diseases [17, 18]. It has been used in the rehabilitation for evaluating the progress and/or degree of the disability documentation [19, 20]. Finally, the NHPT is designed with three rows and three columns of holes (nine holes). It has the benefit of being a shorter version and easier than the GPT and PPT. The NHPT has been used with adult cases with severe and complicated neurological conditions such as the Parkinson's disease and Multiple Sclerosis [21, 22, 23]. Figure 1 demonstrates samples of the GPT, PPT, and NHPT boards. The GPT is a rectangle board with a tray for the 25 pegs and a stopwatch to calculate the time for placing the pegs in the holes [24, 25, 26, 19]. The stopwatch starts once a tested person has picked the first peg and ends with placing the last peg in the hole, then performance time is calculated. However, the manual time calculation might be vulnerable to human errors when switching the stopwatch on and off. The test needs to be held and supervised by a therapist. The aim of this study is to build a prototype of an automated GPT device to calculate the precise performance time and omit any lost time due to human errors. The system is easy to use at home without the supervision of a therapist. This would enable the patients, by themselves, to observe their progression from treatment or their compliance to the home program treatment. The system has an LCD screen reading the elapsed performance time. It mimics the GPT device's configuration in which it has similar dimensions to the

Therefore, the usage of the suggested electronic Pegboard Test (PT) device has been compared against the GPT device. A pilot study was conducted, and the one-sample t-test was calculated, comparing the mean of the measurements from the electronic GPT prototype with the population mean value of measurements from GPT devices. To the best of our knowledge, this is the first pilot study to design an electric and automated GPT; there are no similar experiments in the literature. This research work is structured as follows: Section 2 describes the materials and method, including the geometrical design of the wooden board, electronic circuits, microcontroller (i.e., Arduino MEGA acquisition and processing board), and the display unit (Liquid Crystal Display, LCD). Section 3 demonstrates the results obtained from testing the proposed electronic GPT system.
