Bekhterev–Mendel reflex
Bekhterev–Mendel Reflex
The Bekhterev–Mendel reflex is a neurological phenomenon observed in the human body, specifically related to the reflexive actions of the toes. This reflex is named after the Russian neurologist Vladimir Bekhterev and the German neurologist Kurt Mendel, who both contributed to its discovery and understanding.
Description
The Bekhterev–Mendel reflex is characterized by the flexion of the toes when the dorsum (top) of the foot is tapped or stroked. This reflex is considered a type of superficial reflex, which involves the skin and mucous membranes rather than deep structures like tendons or muscles.
Clinical Significance
The presence or absence of the Bekhterev–Mendel reflex can provide valuable information in a neurological examination. It is often assessed in conjunction with other reflexes, such as the Babinski sign, to evaluate the integrity of the central and peripheral nervous systems.
In clinical practice, the Bekhterev–Mendel reflex may be used to help diagnose conditions affecting the pyramidal tract, which is a major pathway in the central nervous system responsible for voluntary motor control. An abnormal response may indicate a lesion or dysfunction in this tract.
Historical Context
The reflex was first described in the late 19th and early 20th centuries, a period of significant advancement in the field of neurology. Both Bekhterev and Mendel were pioneers in their respective countries, contributing to the understanding of various neurological disorders and reflexes.
Examination Technique
To elicit the Bekhterev–Mendel reflex, the examiner gently taps or strokes the dorsum of the patient's foot. A normal response is the flexion of the toes. The reflex should be tested bilaterally to compare responses between the two feet.
Related Reflexes
The Bekhterev–Mendel reflex is often considered alongside other reflexes such as:
These reflexes are part of a comprehensive neurological examination to assess the function of the nervous system.
