Qualitative changes in dynamic tripod grip between seven and 14 years of age.
The dynamic tripod grip during handwriting was examined among seven- to 14-year-old children. Four components were measured: (a) degree of index-finger flexion; (b) degree of forearm pronation/supination; (c) number of fingers used on the pencil shaft; and (d) thumb and forefinger opposition. Developmental trends were identified for measures (a) and (b), suggesting refinement of the dynamic tripod grip with age.
