In evaluating extremity complaints, the neurological assessment is most useful when there are signs or symptoms that suggest neural involvement. This targeted approach helps you identify issues such as numbness or tingling, weakness, abnormal sensation, abnormal reflexes, or radicular pain, and then localize the problem without spending time on a full neuro workup when there’s no indication of nerve involvement. If there are no neurological signs, a comprehensive neurological exam may not change management and can waste time, whereas focusing on the musculoskeletal or vascular aspects of the extremity is typically more efficient. While a quick screening can be helpful, the emphasis is on performing the neurological exam only when symptoms or signs point to nerve or nerve-root involvement. Peripherals signs and symptoms guide the need for the exam, rather than applying it universally or restricting it to spinal complaints.
