- Distal 1/4
Main function
- RU joint
- Pronation
Nerve innervation
- Segmental

Palpation
- Patient position
- Sitting or supine
- Place your hand distally and laterally on the anterior side of the lower arm
- Localize the radial pulse
- Give resistance towards supination so that the patient is giving force towards pronation
- You can feel on both sides of the radial artery for contraction of the pronator quadratus
Strength test for pronator teres and pronator quadratus
- Patient position
- Sitting or supine
- Stabilize the patient's elbow to avoid abduction movement of the shoulder
- Ask the patient to hold the arm in pronation and partly flexion of the elbow
- Give resistance to the lower part of the forearm just proximal to the wrist in a supinated direction so that the patient is giving force towards pronation
- The patient maintains the position of the arm while giving resistance during the length of the test
