Oppenheim's sign

Oppenheim's sign is a medical sign often used in neurology to test for pyramidal tract dysfunction. It is named after the German neurologist Hermann Oppenheim, who first described it in 1884.

Description

The Oppenheim's sign is elicited by applying downward pressure along the medial side of the tibia. A positive sign is indicated by the involuntary flexion of the hip and knee.

Clinical significance

A positive Oppenheim's sign suggests a lesion of the corticospinal tract, often due to conditions such as multiple sclerosis, amyotrophic lateral sclerosis, or stroke. However, it is not specific and can be seen in other neurological disorders.
