Neurological examination

Neck motor function

Here the examiner tests the strength of the neck muscles, by sensing the force exerted when the subject contracts different muscles against resistance. First, by raising the shoulders; then by attempting to bend the head forward; finally by turning the head to one side. In the second half of the clip, a close-up shows how the various tendons (trapezoidal and sternomastoid) become prominent as the muscles are activated.
