The main feature of AMCT is to analyze the degree of spinal subluxation by measuring the length of two feet. Combined with the principles of biomechanics, neurology and anatomy, the subluxation of the spine in horizontal plane, coronal plane and sagittal plane is corrected by spine activator, so that the human spine can reach a balanced state. Force comparison between freehand correction and activator correction: If freehand correction is adopted, assuming that a force of 540N is applied to the lumbar L4 vertebral body, the vertebral body can move1.1mm.. So although you apply 100% force to the vertebral body, the force acting on the bone is only 20%. If the activator is used for correction, as long as the force of 140N is also applied to the L4 vertebral body, the maximum movable vertebral body can reach1.6 mm. According to research, the * * vibration frequency of the spine from back to front is 30~50Hz. The activator uses pulses close to the vibration frequency of human body, and uses the vibration effect of * * * to effectively amplify the strength and strengthen the therapeutic effect. If you apply a force of 150N, the force can reach 450N due to vibration.
