Manual Spine Chiropractic Adjustment Correction Tool Spine Correction Gun 4 Head Adjust Vertebration Cervical Spine Massager Working principle: The principle of physical pulse, imitating hand massage, uses the principle of muscle resonance to deeply hit and vibrate the deep muscle tissue. While restoring the physiological curvature, it uses the pulse impact force sent by the machine and equipment to open the spinal space and retract the intervertebral protrusion point, so as to eliminate nerve pressure, correct the spine, accelerate blood circulation, relieve pain, and accelerate the recovery after injury. While restoring the curvature of the body, the bone setting gun uses its own gravity to pull open the intervertebral space and retract the herniated point of the intervertebral disc, so as to eliminate nerve compression. Correct the spine and reduce pain. The proper strength will not hurt the spine Function 6 level force can be adjusted 50N, 100N, 150N, 200N, 250N, 300N for massage more effective and comfortable of different body parts.Our 6-level intensity classification is based on the human spine's bearing capacity. If you want to feel the effect, please use on your body.) In order to ensure better massage effect, the strength of the tension spring is very strong, so it look like very stiff. FunctionThis is an adjusting instrument intended for adjustment, mobilization or manipulation of the musculoskeletal joints of the spine and extremities.
