Gordon Reflex
Purpose[edit|edit source]
The Gordon reflex was initially introduced as the “paradoxical flexor reflex” when it was first demonstrated by American neurologist, Alfred Gordon, at the Philadelphia Neurological Society in 1904.[1]It is used to diagnose lesions of the pyramidal tract, and is a helpful adjunct to a complete neurological examination, alongside theBabinski,Chaddock, andOppenheimreflexes.[2]It is particularly useful in cases where the examiner is unable to elicit aBabinski reflexdue to poor cooperation of the patient or when there is an equivocal result.[3]
Technique[edit|edit source]
Setup: The patient is positioned in supine lying, with legs extended and relaxed.
Procedure: The examiner lifts the patient’s leg at the ankle with one hand, and with the other hand grasps the patient’s calf. Next, the examiner squeezes the patient’s calf muscle tightly, while monitoring the toes.[1]
Response:
正常的(消极的)响应is no reaction at the toes. An abnormal (positive) response is an ipsilateral extensor plantar reflex - extension of the hallux with fanning of the other toes.
Evidence[edit|edit source]
A double-blind study of the consistency of theBabinski reflex和它的变体(Chaddock, Gordon, andOppenheimreflexes) gave the Gordon reflex a fair rating for inter-observer consistency with a kappa of 0.3515 (95% CI = 0.255-0.488) and the highest intra-observer consistency with a kappa of 0.6731.[3]
