Hypertonicity in the biceps and the flexor digitorum profundus (FDP) may result in which of the following contractures and subsequent functional limitations?

Question

Quizplus · Accepted Answer

Hypertonicity in the biceps and the flexor digitorum profundus (FDP) would lead to a tendency for both elbow flexion and wrist flexion due to the primary actions of these muscles. This could result in contractures that limit the ability to extend the elbow and wrist, thereby affecting the ability to reach and grasp objects effectively, particularly with a lumbrical grip which requires a more extended wrist position for optimal function.
