Babinski Test for Asynergy

The Babinski asynergy test (or Babinski phenomenon) is a neurological test that identifies lesions in the central nervous system.

The essence of the test is as follows: the doctor runs a sharp object (usually a toothpick) along the outer edge of the foot from the heel to the toes. In healthy people, this causes a downward flexion movement of the toes. In patients with lesions of the central nervous system, on the contrary, an extension movement of the toes occurs upward and to the sides - the so-called Babinski symptom.

This indicates asynergy - a violation of the coordinated interaction of synergist and antagonist muscles. A positive Babinski sign indicates damage to the spinal cord pathways.

The test is widely used by neurologists to diagnose diseases of the nervous system.
