Pinch strength norms for 5-to 12-year-olds.

Functional performance evaluations and intervention planning for children and youth is informed by comparisons of their performance to normative standards. The literature contains little data regarding the developmental norms for children on pinch strength. A random sample of 414 children was assessed on three separate measures of pinch strength. Pad-to-pad, three-jaw chuck, and lateral pinch were evaluated using the B & L Engineering pinch gauge while utilizing the standard positioning recommended by the American Society of Hand Therapists. The results were divided into distinct categories for 5-to 12-year-olds. The resulting normative data provide standards for pinch strength in children to be used in the clinical setting.
