The pelvic bone is medically known as the pelvis. When the pelvis is correct, the symptoms of lumbar muscle strain may be alleviated. There are two types of pelvic malposition: anterior tilt and posterior tilt. Anterior tilt of the pelvis will cause an imbalance of force on the muscle ligaments around the spine, and the muscles of the lumbar major muscles on both sides are tense, which may lead to lumbar muscle strain. Its common symptoms include recurrent low back pain, etc. Correcting anterior pelvic tilt can gradually relieve the symptoms of low back pain. In daily life, adjusting poor posture, whether sitting or standing, should keep the lower back flat so that the lower back avoids excessive anterior tilt. If pelvic malposition or lumbar muscle strain occurs, it is recommended to go to the hospital in time for standardized treatment under the guidance of the doctor.
