The recovery time of cervical physiological curvature straightening is related to the following factors: 1. The longer the cervical physiological curvature disappears, the longer the recovery time will be, because the physiological curvature is the cervical vertebrae, cervical intervertebral ligaments, cervical muscles and cervical intervertebral joints work together to manifest the cervical vertebrae shape. If it is determined that the cervical spine physiological curvature straightening is not too long, the whole process is not more than a year, the cervical vertebrae and cervical spine joints will not have too obvious growth and change and the cervical intervertebral ligaments are not too relaxed, muscle damage is not too heavy then after a period of treatment and exercise will make the physiological curvature recovery, about three months or less. 2, whether due to cervical vertebrae injury or ligament If the cervical spine physiological curvature disappears because of the fracture and the cervical spine hyperplasia change, the physiological curvature can only be treated by surgery, while the simple posture causes or ligament muscle lesion injury has a chance to recover.
