Final answer:
Injury to the peroneal nerve typically results in foot drop, as this nerve affects lower extremity function and not the upper extremities or different neural pathways.
Step-by-step explanation:
Injury to the peroneal nerve commonly results in foot drop, which is a condition where patients experience difficulty in lifting the front part of the foot. This neurological exam finding often indicates that the lower motor neurons (LMNs) are not functioning properly. The peroneal nerve is part of the peripheral nervous system and primarily affects lower extremity function; an injury would not typically cause tingling in the fingers, decreased handgrip strength, or muscle spasms, as these are more related to the upper extremities or different neural pathways.
