In relaxing the =muscles= of the =lumbar region= have the patient on the side upon the table; then flex the thighs upon the abdomen with your weight against the knees so as to control all movements of the patient; reach over the patient with the fingers upon the contracted tissues and manipulate them outward and upward on either side until they are relaxed. A method sometimes employed to relax the muscles of the dorsal, lumbar and sacral regions is to place the patient flat on his face upon the table; then by pushing up on the muscles from above downward with the flat of the hand they are easily relaxed. This treatment should be especially given when the patient’s muscles are contracted by atmospherical changes and from standing in one position for a long time. When the muscles of the back are contracting they draw downward and many times draw the ribs with them, as well as tensing the tissues over the sacral foramina and obstructing or irritating the sacral nerves. By using the modern table longitudinally relaxing, or stretching, the lumbar and dorsal musculature saves considerable strength and effort of the physician. To correct =vertebral lesions= of the =dorsal region= the same rules should be followed as in treating lesions of the cervical vertebræ. Treatments may be given with almost equal ease whether the patient is lying on the side or sitting up. To illustrate the treatment of the dorsal region when the patient is lying down, assume that there exists a lateral lesion, combined rotation and sidebending, between two vertebræ; if the lesion is below the seventh dorsal use the legs as a lever, and if the lesion is above the seventh dorsal use the head and neck as the lever. Have the patient lie upon the side toward which the lesion is pronounced, either reach under the neck or around the limbs with one hand, and with the other hand upon the lesion bend the head and neck or the thighs in such a manner that the angle of the flexion is directly over the break in the spinal column; this is to exaggerate the lesion; then by lightly lifting up on the neck or limbs and with a slight rotation of this lever the flexed parts should be extended, at the same time exerting pressure with the hand over the lesion in such a manner that the vertebra is pushed forward toward its normal position.
