Brachialis
Pronator teres
Brachialis
During active elbow ROM, your 32-year-old male patient had 125 degrees of flexion. During passive elbow ROM, the same patient had 140 degrees of flexion. What might have caused the difference between these two measurements?
Active insufficiency of the flexors
Passive insufficiency of the extensors
Torsion in the capsular ligaments
Muscle belly bulk
Muscle belly bulk
