Which sign is assessed by observing the response of a patient's big toe and toes when the sole of the foot is stroked?

The sign assessed by observing the response of a patient's big toe and other toes when the sole of the foot is stroked is known as Babinski's Sign. This neurological reflex is evaluated by applying a stimulus along the lateral aspect of the sole, starting from the heel and moving towards the toes. In a typical response, especially in infants, the big toe will extend upward and the other toes may fan out. In adults, a positive Babinski's Sign, where the big toe extends instead of flexes, can be indicative of neurological damage, specifically within pathways originating from the brain that control reflexes.

Understanding Babinski's Sign is important for assessing neurological function. Its presence in adults may suggest conditions such as spinal cord injury, multiple sclerosis, or other central nervous system disorders. Recognizing the implications of this sign plays a vital role in identifying potential issues that need further investigation or immediate intervention in a medical setting.
