Other than Babinski sign, what other signs do you know ?
In upper motor neuron lesion, the big toe will dorsiflex with the following :
Gordon reflex – On applying pressure to the muscle of the calf
Oppenheim sign – on applying heavy pressure with thumb and index finger to the shin, stroking downwords from below the knee down to the ankle
Bing reflex – when the dorsum of the toe is pricked with a pin
Schaefer reflex – pinching the Achilles tendon sufficiently to cause pain
Chadock reflex – on stroking the lateral side of the foot, beginning below the malleolus and extending anteriorly along the dorsum of the foot to the base of the big toe
Gonda reflex – grasping the small toes between the fingers, slowly and forcibly flexing the toe and then suddenly releasing the toe
I know an MRCP examiner who likes to ask this question. Try practicing it ! Physical examination is the most crucial step in Neurology.
