Asymmetrical tonic neck reflex

The fencing posture is a term used in medicine, refers to a characteristic reminiscent of the state of a fencer's posture.

Posture

In the fencing posture the head is rotated to one side, thus located in the lateral position. The extremities of the face side are stretched, the rear main page are in flexion. Also, on the side of the face a more open, to watch on the occipital side of a rather closed fist.

Clinical Relevance

Paediatrics

In pediatrics, the fencer is valid in the infant as a physiological phenomenon that represents the neural development and can be observed from about the 4th and up to the 8th week after birth. The boundary with the pathological persistent Asymmetrical tonic neck reflex ( ATNR ) carried out by the fist, who also appears on the face side with the persistent ATNR. The triggering of this posture is made ​​possible by a passive ( externally added ) rotation of the head in the supine position.

Neurology

In neurology, the involuntary, not always immediately resolvable taking the fencing posture to a persistent ( ie longer than usual physiologically persistent ) Asymmetrical tonic neck reflex ( ATNR ) point. This can ( especially at a poorly trained and automated cross pattern ) can lead to deficits in movement coordination. Furthermore, through the associated with the ATNR Tonusreaktion also a non-physiological Pin Retention ( tendency to spasm of the writing hand) and a deficit graphomotor frequent effects. Secondarily it comes from a badly automated cross pattern, likely to deficits in the areas of perception and cognitive performance, which are connected with cross pattern ( eg, dichotic hearing achievements, language structure, structure total benefits, including daily structure, action planning, etc.).

Forensic Medicine

At death by charring it may by a general contraction of the muscles, in which the strong trained flexor muscles ( flexors ) outweigh come to assume the fencing posture, which can give the right medical evidence of the cause of death.
