An OT practitioner is working with a client who must wear a thumb spica splint for 3 more weeks after cast removal for a scaphoid fracture

A. Thumb extension
B. Thumb flexion
C. Palmar prehension
D. Hook grasp
ANS: C
Thumb flexion and extension positioning full time in the splint would not allow use of the thumb for light activities. Hook grasp does not require the use of the thumb. Palmar prehension allows for thumb pad-to- pad opposition and holding small objects, lifting objects from a surface, and tying a bow.
