Percussion test of the vertex:
The patient sits erectly. The doctor puts one hand on the patient's vertex with the palm downward, and uses the fist of the other hand to strike his dorsum of the hand on the vertex. If the patient feels pain in his neck, or the pain is radiating to the upper limb, it is positive. This is often seen in cervical spondylopathy.

Compression test of intervertebral foramen:
The patient sits erectly with his head inclined slightly to the posterior aspect of the diseased side. The doctor stands behind the patient, puts his two hands crossly on the patient’s vertex and presses downward, making the intervertebral foramen smaller. If there occurs pain in the neck and the pain is radiating to the upper limb, it is positive. This is often seen in cervical spondylopathy.

Traction test of brachial plexus:
The patient sits erectly with his head deviated to the normal side. The doctor puts one hand on patient's diseased side of head, grasps the wrist of the diseased side with the other hand to make the upper limb abducted, then gives opposite pull and traction. If the cervical pain becomes severer, and the diseased limb is painful and numb, it is positive. This is often seen in cervical spondylopathy.

Deep respiratory test:
It is also called Adson’s syndrome, and used for the examination of scalenus anticus syndrome, that is, whether the subclavian artery is compressed because of the atrophy or spasm of anterior scalene muscle. The patient sits erectly with his two arms on the knees, holds the breath after a deep respiration, then faces upward with the chin turned to the diseased side. The doctor presses the patient’s shoulder of the diseased side with one hand, and feels the radial artery of the diseased side with the other hand. If the pulsation obviously becomes week or disappears, and the pain gets serious, it is positive.

Test of throwing out chest:
This is used for the examination of costoclavicular syndrome or whether the subclavian artery and brachial plexus are compressed in the area between the clavicle and the first rib. The patient stands upright with his chest out and two arms extended backward. If the pulsation of the radial artery becomes weak or disappears, and there occurs numbness or stabbing pain in the arm, it is positive.
