What should be assessed in peripheral nerve evaluations of the upper extremities?

The assessment of peripheral nerves in the upper extremities primarily involves evaluating both motor strength and sensory function. This is crucial because the integrity of peripheral nerves can be assessed through their ability to transmit signals that control muscle movement (motor function) and sensation (sensory function).

Evaluating motor strength helps identify any weakness or paralysis that may indicate nerve damage or dysfunction in specific muscles innervated by those nerves. Sensory function assessment, on the other hand, determines whether the patient is able to perceive touch, pain, and temperature, which are essential for everyday activities. Together, these evaluations provide a comprehensive view of the neurological status of the upper extremities.

Other options, while relevant in different contexts, do not specifically reflect the primary focus of peripheral nerve evaluations. For instance, muscle size and skin temperature may indicate issues related to neuromuscular conditions or circulatory problems but don't directly assess nerve function. Joint stability and range of motion are more pertinent to musculoskeletal evaluations rather than peripheral nerve assessments. Lastly, while circulation and pulse quality are vital for vascular evaluations, they do not directly indicate nerve integrity.
