Brissaud's reflex is a clinical sign in which stroking the sole of the foot elicits contraction of tensor fasciae latae. This can occur when there is no movement of the toes, and is part of the extensor plantar response (Babinski's sign).
The sign is named after Édouard Brissaud.
Brissaud's reflex at Who Named It?
Pierre Brissaud was a French Art Deco illustrator, painter, and engraver whose father was Docteur Edouard Brissaud, a student of Docteur Charcot. He was born in Paris and trained at the École des Beaux-Arts and Atelier Fernand Cormon in Montmartre, Paris. His fellow Cormon students were his brother Jacques, André-Édouard Marty, Charles Martin, Georges Lepape. Students at the workshop drew, painted and designed wallpaper, furniture and posters. Earlier, Toulouse-Lautrec, van Gogh, and Henri Matisse had studied and worked there. His older brother Jacques Brissaud was a portrait and genre painter and his uncle Maurice Boutet de Monvel illustrated the fables of La Fontaine, songbooks for children and a life of Joan of Arc. A first cousin was the celebrated artist and celebrity portrait painter Bernard Boutet de Monvel.
In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action and nearly instantaneous movement in response to a stimulus. A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain. The reflex is then an automatic response to a stimulus that does not receive or need conscious thought.
The plantar reflex is a reflex elicited when the sole of the foot is stimulated with a blunt instrument. The reflex can take one of two forms. In healthy adults, the plantar reflex causes a downward response of the hallux (flexion). An upward response (extension) of the hallux is known as the Babinski response or Babinski sign, named after the neurologist Joseph Babinski. The presence of the Babinski sign can identify disease of the spinal cord and brain in adults, and also exists as a primitive reflex in infants.
The patellar reflex or knee-jerk is a stretch reflex which tests the L2, L3, and L4 segments of the spinal cord.
Brudziński's sign or a Brudziński sign is any of three medical signs, all of which may occur in meningitis or meningism. All three are named after Józef Brudziński. In English, the name is often written without the diacritic (Brudzinski) and is pronounced.
In medicine, Infantilism is an obsolete term for various, often unrelated disorders of human development, up to developmental disability, which consist of retention of the physical and/or psychological characteristics of early developmental stages into a relatively advanced age.
Primitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuli. These reflexes are suppressed by the development of the frontal lobes as a child transitions normally into child development. These primitive reflexes are also called infantile, infant or newborn reflexes.
Édouard Brissaud was a French physician and pathologist. He was taught by Jean Martin Charcot at Pitié-Salpêtrière Hospital. He had interests in a number of medical disciplines including motion disturbances, anatomy, neurology and psychiatry. He died of a brain tumour, aged 57.
Hoffmann's reflex is a neurological examination finding elicited by a reflex test which can help verify the presence or absence of issues arising from the corticospinal tract. It is named after neurologist Johann Hoffmann. Usually considered a pathological reflex in a clinical setting, the Hoffmann's reflex has also been used as a measure of spinal reflex processing (adaptation) in response to exercise training.
Westphal's sign is the clinical correlate of the absence or decrease of patellar reflex or knee jerk. Patellar reflex or knee jerk is a kind of deep or stretch reflex where an application of a stimulus to the patellar tendon such as strike by a solid object or hammer caused the leg to extend due to such stimulus causes the quadriceps femoris muscle to contract.
The Bekhterev–Jacobsohn reflex, or Jacobsohn's finger flexion sign, is a clinical sign found in patients with pyramidal tract lesions of the upper limb. In this condition, stroking the dorsum of the forearm, in the area of the distal radius, with the arm supine causes abduction of the hand and flexion of the fingers.
The Hannington-Kiff sign is a clinical sign in which there is an absent adductor reflex in the thigh in the presence of a positive patellar reflex. It occurs in patients with an obturator hernia, due to compression of the obturator nerve.
Throckmorton's reflex is a clinical sign in which pressure over the dorsal side of the metatarsophalangeal joint of the big toe elicits a plantar reflex. It is found in patients with pyramidal tract lesions, and is one of a number of Babinski-like responses.
The Lazarus sign or Lazarus reflex is a reflex movement in brain-dead or brainstem failure patients, which causes them to briefly raise their arms and drop them crossed on their chests. The phenomenon is named after the Biblical figure Lazarus of Bethany, whom Jesus Christ raised from the dead according to the Gospel of John.
Laurent Brissaud is a French slalom canoeist.
Woltman's sign is a delayed relaxation phase of an elicited deep tendon reflex, usually tested in the Achilles tendon of the patient.
