The 'Babinski sign' refers to the observable response during the Babinski reflex test. It is tested by stroking the sole of the foot. 🦶 A positive Babinski sign means the big toe extends upwards and the other toes fan out, which is normal in infants but abnormal in adults. It may indicate a problem in the nervous system. Named after neurologist Joseph Babinski. 👨⚕️ Interpreting the sign helps diagnose neurological conditions. Consider it the 'observable result' of the Babinski test.
