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

The physician has allowed the patient to use the hand with the splint in place for light activities. When making the splint, the therapist must be sure to position the thumb in what position to al-low light activities?
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.
