The goal of the thesis was the comparison of the effect of the postisometrical relaxation and manual centration according to Čápová on the trigger points in musculus trapezius when the patient suffers from cervical pain syndromes. The patients were divided into the groups A and B; group A was treated by postisometrical relaxation, and group B by manual centration according to Čápová. The trigger points were detected by the combination therapy. The combination therapy uses the different irritation of hypertonic fibers by electrical stimulus. The numeric value of the treshold motoric intensity was taken down before the therapy, after the therapy and the next day. The thesis shows that both therapies work on a different neurofysiological basis but they have the same statistically significant effect on removing the trigger points in the muscles. The intent of the centration of shoulder is not treating the trigger points in the muscle; this is the focus of the postisometric relaxation. The removal of the trigger points is only a side effect of the centration, due to coactivation of muscles round the centration joint.
