- The plantar reflex is a reflex elicited when the sole of the foot is stimulated with a blunt instrument. The reflex can take one of two forms. In normal adults the plantar reflex causes a downward response of the hallux (flexion). An upward response (extension) of the hallux is known as the Babinski response or Babinski sign.
The following are Babinski-like reflexes used to find out if there are any pyramidal tract lesions of the lower limbs. The bolded terms are the ones that students are required to know in the Ilmu Penyakit Saraf department.
- Chaddock's sign: By stroking the lateral malleolus.
- Gordon's sign: Squeezing the calf muscle
- Oppenheim sign: Applying pressure along the shin of tibia.
- Gonda's sign: pressing the 4th toe downwards and then releasing it with a snap.
