The Effect of Auditory and Motor Cognitive Distractions on the Neural Provocation Test in Subjects With Neck Pain

The patient is placed in a supine position and his cervical spine with 25º of lateral flexion on the opposite side of the member in which we perform the test. First a passive scapular depression is performed, 90º of shoulder abduction combining external shoulder rotation. Next, a supination of the forearm is performed with wrist extension and finger extension. Finally, the elbow is extended to the limit of resistance or when the investigator observes the elevation of the shoulder girdle.

Neural provocation of the median nerve is performed but an auditory distraction is added with a metronome with a constant time of 50 beats per minute.
