Introduction[edit | edit source]
Dr. Johann Hoffmann, a German neurologist, is credited with the discovery of the eponymous Hoffmann's sign or reflex.[1] Although his assistant, Dr. Hans Curschman is responsible for the dissemination of this finding, leading to its universal use in neurological screening today.[2]
Purpose[edit | edit source]
This test evaluates the structural and functional integrity of the corticospinal tract.
Technique[edit | edit source]
- Place the subject’s relaxed hand ensuring dorsiflexion at the wrist and partial flexion of the fingers.
- Hold the subject's partially extended middle finger between your index and middle finger.
- Perform a sharp and forceful flick of your thumb, making contact with the nail of the subject’s middle finger.
- The subject's finger will flex immediately followed by relaxation.
- The presence of Hoffman sign is characterized by flexion and adduction of the thumb and flexion of the index finger.
