When should you test for weakness of neck flexion or extension in a patient?

A: When there is distal weakness of the legs.

B: When there is proximal weakness of the arms.

C: When there is weakness of the facial muscles.

D: When there is weakness of the respiratory muscles.

You should test for weakness of neck flexion or extension when you find proximal weakness of the arms. This is because such weakness is characteristically present in myopathies and myasthenia gravis. Testing neck flexion and extension helps in diagnosing these conditions, as they often affect the muscles responsible for these movements.
