The Purdue Pegboard Test (Lafayette Instrument Company, Lafayette, IN, USA) was used to assess unimanual and bimanual finger and hand dexterity. During this test, the participant tries to put as many pins as possible in holes of a test board within 30 s. First, the participant performs the exercise with the dominant hand, then with the non-dominant hand, and then with both hands. Each condition was performed three times for 30 s. The averages of the three trials of each condition were used for the statistical analysis. Furthermore, the average of the three scores (dominant, non-dominant, both hands = Σdnb) was calculated as additional score [To measure the reaction time, the Fall Stick Test was used on both hands. The fall stick apparatus was a wooden 1.30 m-long rod with measurement markings. A rubber disc with a diameter of 7.5 cm and a weight of 280 g was connected to the lower end of the stick to stabilize the vertical fall of the stick. Before the start of the test, the participant sat at the side of a table and put his/her forearm with an open hand on the table. The open hand was at the edge of the table. The fall stick apparatus was positioned vertically by an examiner over the participant’s hand, right between the thumb and the index finger without touching the rubber disc. The disc was aligned with the top of the participant’s hand. The examiner released the apparatus in random time intervals ranging from 4 to 10 s, and the participant had to catch the apparatus as quickly as possible. When the participant caught the stick, the distance from the top of the disc to the most superior part of the participant’s hand was recorded. The participant started the test with the dominant hand.After three practice trials, the participant performed eight experimental trials. For analysis, the best- and worst-performed trial were excluded and the average of the remaining six trials was used for further analysis [The dynamic balance performance was assessed with the Y Balance Test (Y Balance Test Kit™). The Y Balance Test consists of a stance platform from which three PVC pipes are attached in the anterior, posteromedial, and lateral directions. A moveable box is attached to each of the pipes. While standing with one leg on the platform, the participant had to push the box as far away from him/herself as possible. The test procedure started with four practice trials [
