Effects of Arm Measurements on Upper Limb Skills and Reaction Time

In this study, upper extremity anthropometric characteristics, functional upper extremity skills, and reaction time will be examined in healthy young adults. A total of 46 healthy individuals aged between 18 and 25 years, with no history of systemic disease or upper extremity injury affecting functional performance, will be included. Upper extremity anthropometric measurements, including arm, forearm, and hand lengths and circumferential measurements, will be obtained using standardized procedures. Functional upper extremity skills will be assessed using the Purdue Pegboard Test, and reaction time will be evaluated using the Nelson Hand Reaction Test. Correlation analyses will be performed to examine the relationships between upper extremity anthropometric characteristics, functional upper extremity skills, and reaction time.
