Where is sensory testing performed on the arms?

Sensory testing on the arms is typically performed at key anatomical locations that are relevant for assessing nerve function and sensory perception. The deltoid region, just below the elbow, and the wrist represent critical points for evaluating sensory integrity associated with the brachial plexus and the radial, ulnar, and median nerves.

Testing in the deltoid region helps assess the sensory distribution of the axillary nerve, which can be affected in shoulder injuries. The area just below the elbow allows for evaluation of sensory involvement in the forearm, which is crucial for determining any underlying neuropathies. The wrist is another critical site where sensory testing occurs, as the median nerve is particularly significant in carpal tunnel syndrome assessments.

This choice encompasses a logical progression from proximal to distal sensory testing points on the arm, ensuring a comprehensive assessment of sensory function in this region.
