A reflex action in which the big toe remains extended or extends itself when the sole of the foot is stimulated, abnormal except in young infants.
- ‘Because of the erroneous assumption that the change in the Babinski reflex was necessarily beyond an individual's volitional control, the experimenters had not employed a control group.’
- ‘The Babinski reflex is not, in and of itself, diagnostic for a particular condition.’
- ‘But the two are not entirely the same as the Babinski reflex evaluates the fanning of the large toe and animals do not have this.’
- ‘He realized since 1896 that the Babinski reflex was part of the flexor reflex synergy.’
- ‘The deep reflexes were hyperactive; the Babinski reflexes were positive.’
Named for Joseph François Felix Babinski (1857–1932), French neurologist.
