The Relationship Between Finger-Hand Length And Hand Width With Dexterity In Healthy Individuals

The hand is capable of performing complex specialized tasks that require dexterity, manipulation, and tactile sensitivity.(Polat, 2023) Hand performance on a task is a combination of different skills, including grip muscle strength, movement, tactile feedback, and motor coordination. (Imamura, Rissanen, Kinnunen, & Rintamäki, 1998). To achieve these, the hand is equipped with mechanical and sensory abilities.(Dianat, Haslegrave, & Stedmon, 2012) Dexterity is a motor skill determined by the range of motion of the hands and fingers, as well as the ability to manipulate. It is a combination of reaction time, touch sensation, nerve conduction, grip strength and mobility. While finger dexterity is related to the fine motor skills required to move relatively small objects, manual dexterity includes the gross motor skills required to hold relatively large objects.(Roman et al., 2023) The most common dexterity tests reported in the literature include the Box-Block Test, Purdue Pegboard Test, Jebsen Taylor Test, 9-Hole Peg Test (NHPT), and Roeder Manipulative Ability Test.
