Simple Test for Evaluating Hand Function (STEF). The STEF, which was developed in Japan, is a test for evaluating the patient’s ability to pinch, grasp and transfer objects. The patient is required to pick up items one by one from a storage space and move them into a target space as quickly as possible. The subject performs the object-moving tests using 10 kinds of objects with different shapes and sizes, including (1) six small cubes (1.5 cm on a side), (2) six middle-sized cubes (3.5 cm on a side), (3) five large cuboids (5 cm long, 10 cm wide and 10 cm tall), (4) six small balls (0.5 cm in diameter), (5) six middle-sized balls (4 cm in diameter), (6) five large balls (7 cm in diameter), (7) seven metallic circular disks (2 cm in diameter and 0.2 cm thick), (8) six wooden circular disks (3 cm in diameter and 1 cm thick), (9) eight pins (0.3 cm in diameter and 4 cm long) and (10) six pieces of cloth (9 cm long and 7 cm wide).
