Abstract: A chain treatment method reduces muscle tonus, reduces joint contractions, acquires body symmetry, and improves motor function and coordination in patients having problems of motor functions, such as cerebral palsy or scoliosis. The method comprises a routine having three interrelated and interdependent states: relaxation, stretching, and then fixing the results obtained after the relaxation and stretching. The relaxation state comprises applying pressure on all points of influence on the body of the patient. The stretching state comprises stretching the body of the patient by hanging the patient on a horizontal bar with the arms in a substantially vertical position. And the fixing state comprises hydrotherapy where the patient is suspended in a pool of water at about 34°-36° C. with the therapist holding the patient under the head and coccyx. The method is performed in sequential order from relaxation to stretching and then to fixing.
