Reflex Adductor Dorsal

Dorsal adductor reflex

The dorsal adductor reflex (r. adductorius dorsalis) is a protective reflex that occurs when the spinal cord or its roots are damaged. It consists of contracting the adductors of the thigh and lower leg, which helps protect the joint from further damage.

Description of the reflex

When the spinal cord is damaged, such as in a spinal cord injury, control of the adductor muscles occurs. This leads to the fact that when trying to move the leg to the side, the adductor muscles cannot perform their function and the leg remains in the same position. In response to this, the dorsal adductor reflex occurs, which consists in the fact that the adductor muscles contract and hold the leg in the desired position.

This reflex can be used to diagnose spinal cord injuries. If the leg remains motionless during the dorsal adductor reflex test, this may indicate damage to the spinal cord and the need for a more detailed examination.

Also, the dorsal adductor reflex can occur in other diseases, such as polyneuropathy, myelopathy, multiple sclerosis, etc. In this case, the reflex may be less pronounced or absent altogether.

Conclusion

The dorsal adductor reflex is an important protective reflex that occurs when the spinal cord is damaged. It helps protect the joint and prevent further damage. When performing a test for this reflex, disorders in the functioning of the spinal cord and other diseases associated with the nervous system can be detected.

The adductor reflex, or dorsal reflex, is a reaction of the muscles of the upper limb belt, which consists in contracting the back muscles and moving the arm to the side.

The dorsal adductor is also known by different names: In the neurological literature, the reflex is called the Chublov-McCarthy reflex, the cruciate muscle reflex, the concus-positive reflex, or, in the English-language literature, the E-D reflex. The dorsal adductor reflex, or Spinoza reflex. Kaufmaier reflex. In embryology and experiment it is called the "fusion reflex" since it has only one existence during the initial fusion of the segments.

There are also two different theories that explain the origin of this reflex: the neurogenic theory of origin (Hippocrates, Galen, Avicenna) reports that this reflex arises on a spinal basis, and its work is explained only by the removal of fibers from the lower brain segments; (b) motor theory of origin, interprets the formation of this reflex by impulses in the central nervous system segment; as an adaptation caused by Chockenberg functioning and providing feedback and lateral stability of the spinal cord
