The Gordon reflex sign, also known as the stroking reflex, is a neurological test used to assess the function of the spinal cord. It is named after James Gordon, who first described it in 1904. The correct spelling of this term is /ˈɡɔːrdən ˈriːflɛks saɪn/. The "Gordon" part is pronounced with a long "o" sound and a silent "d", while "reflex" and "sign" are pronounced with a short "e" sound and a silent "g". Correctly spelling medical terms is crucial for clear communication among healthcare professionals.
The "Gordon reflex sign" is a medical term that refers to a physical response observed in patients with a specific neurological condition. It is characterized by the involuntary flexion of the fingers when the tip of the examiner's finger is pressed against the patient's flexor tendon in the forearm.
This reflex sign is named after William James Gordon, a British neurologist who first described it in the early 20th century. The Gordon reflex sign is commonly associated with certain spinal cord lesions, particularly those involving the upper motor neurons. It is considered to be an abnormal, hyperactive reflex in these patients, indicating a disruption in the normal functioning of the nervous system.
When examining a patient for the Gordon reflex sign, the examiner will apply gentle pressure on the flexor tendon in the forearm, near the wrist, with their finger. In individuals with an intact neurological system, this maneuver should not cause any involuntary finger movement. However, in patients with a positive Gordon reflex sign, the fingers will tend to flex involuntarily, even with minimal pressure applied to the tendon. This reflex response can be easily observed and is often used as an indication of upper motor neuron lesions.
The Gordon reflex sign is an important clinical finding that aids in the diagnosis and assessment of various neurological conditions. It helps healthcare professionals identify the presence and extent of spinal cord lesions, contributing to a more comprehensive understanding of a patient's neurological status.
