Which of the following factors would explain why there is a weaker grip on the ulnar side of the hand?
A) Active finger flexion range of motion (ROM)increases from the radial to the ulnar side of the hand,lending to increased occurrence of active insufficiency of the ulnar digits.
B) Active finger flexion ROM increases from the ulnar to the radial side of the hand,lending to increased occurrence of active insufficiency of the radial digits.
C) Active finger flexion is the same in all fingers.
D) Weaker grip is not possible with the ulnar side of the hand.

Question

Quizplus · Accepted Answer

Active finger flexion range of motion increases from the radial to the ulnar side of the hand, which leads to increased occurrence of active insufficiency of the ulnar digits. This means that the muscles responsible for finger flexion are unable to generate as much force on the ulnar side due to the stretched position of these muscles. Therefore, the grip strength is weaker on the ulnar side of the hand.
