著者：Loh, Ping Yeap; Yeoh, Wen Liang; Nakashima, Hiroki; Muraki, Satoshi題名：Deformation of the median nerve at different finger postures and wrist angles発表情報：PeerJ 巻: 2018 号: 8 ページ: - キーワード：概要：Background. The objective of this study was to evaluate the changes of the median nerve cross-sectional area (MNCSA) and diameters of the median nerve at different finger postures and wrist angles. Methods. Twenty-five healthy male participants were recruited in this study. The median nerve at wrist crease was examined at six finger postures, and repeated with the wrist in 30° flexion, neutral (0°), and 30° extension. The six finger postures are relaxed, straight finger, hook, full fist, tabletop, and straight fist. Results. The main effects of both finger postures and wrist angles are significant (p < 0:05) on changes of the MNCSA. Different finger tendon gliding postures cause a change in the MNCSA. Furthermore, wrist flexion and extension cause higher deformation of the MNCSA at different finger postures. Discussion. The median nerve parameters such as MNCSA and diameter were altered by a change in wrist angle and finger posture. The results may help to understand the direct biomechanical stresses on the median nerve by different wrist-finger activities.抄録：英語フィールド
