Abstract: A patient suffering from a condition of spinal muscle imbalance is treated by the application of controlled impact forces applied at specific points to the patient's neck. The point of application is to one side or the other of the spine at the rear of the patient's neck. The side to which the impact forces are applied is determined by areas of the body at which prior trauma has occurred that created the condition of spinal muscle imbalance. The forces are applied against the rear of the patient's neck directly below the head and at a force application point immediately at the splenius muscle and between the attachment of the superior border of the trapezius and the sternocleido mastoideus muscles to the patient's head. the impact forces are of a selected magnitude of between about four ounces and five pounds and are applied at a rising angle of about twenty five degrees toward the eye socket-temple area of the opposite side of the patient's head.
