Data are expressed as the median (25th-75th percentile). Pinch-I: thumb-index fingertip pinch strength; Pinch-M: thumb-middle fingertip pinch strength; Pinch-R: thumb-ring fingertip pinch strength; Pinch-L: thumb-little fingertip pinch strength. A value < 0.05 was considered to indicate statistical significance.
