Reflex Styloradial

The Styloradial reflex (r. Styloradialis) is a reflex that occurs when the styloid process of the radius is irritated. This reflex is one of the main reflexes that are used in the diagnosis of various diseases of the nervous system.

The styloid process of the radius is located on its lateral surface and is a small protrusion that serves for attachment of muscles and ligaments. When this process is irritated, reflex muscle contractions occur, which are innervated by the radial nerve.

The styloradial reflex can be induced in various ways, for example, by mechanical stimulation of the process, insertion of an electrode into its area, or application of ultrasound. Normally, when the process is irritated, a contraction of the supinator and wrist extensor muscles occurs. However, if the styloradial reflex is impaired, this may indicate various diseases of the nervous system, such as spinal cord injuries, brain injuries, stroke, multiple sclerosis and others.

Thus, the styloradial reflex is an important diagnostic tool for assessing the state of the nervous system and identifying various diseases.

Styloradial reflex

The Styluradialis (or Stauroradius) reflex (Stylogramus) is a reflex caused by electrical stimulation of the forearm casing, which consists of flexion and adduction of the shoulder. When performing this reflex, the hand is placed in the extreme position of supination, and its elbow is tilted back. Through Stiluradial, the shoulder is pulled out of flexion, and, as the name of the reflex implies, the arm is raised in the direction of the corresponding action of the palmar nerve, which penetrates
