Urinary frequency caused by lumbar intervertebral disc herniation is not rare, and it is often misdiagnosed or unrecognized clinically, which brings great pain to patients physically and mentally. Pelvic rotation and repositioning method for the treatment of urinary frequency caused by lumbar disc herniation is effective, practical, quick-acting, easy to operate, less pain to the patient, low recurrence rate, no sequelae and other characteristics. 1, treatment method: pelvic rotation reset method: the patient sits on a square stool, feet apart and shoulder width, the doctor sits behind the patient to reset the left sacroiliac joints, for example, the doctor’s right hand from the patient’s right armpit to the front, palm pressure on the back of the neck, the thumb down, the remaining four fingers to support the left neck, and at the same time, the patient is asked to feet on the ground, the hips are not allowed to move (the assistant to face the patient to stand, the patient’s left thigh two legs clamped, the patient’s left thigh, both hands press the left thigh root). (the assistant stands facing the patient, holding the patient’s left thigh with both legs and pressing the patient’s left thigh with both hands). The left palm of the doctor holds the iliac bone of the left sacroiliac joint, and then the right hand pulls the patient’s neck, making the patient bend forward and rotate to the right at the same time. In the process of the patient’s forward bending and rotating, the doctor’s left palm pushes the left iliac bone, and there is often a “kada” sound, and the reset is completed. The right sacroiliac joint is reset in the opposite way, and the method is the same. Manual therapy 1~2 times/week, should not be too diligent. 2, the movement of the pelvis is a three-dimensional movement: the pelvis appears to be tilted forward and backward, the pelvis rotates around the sagittal axis in the frontal plane, and the pelvis appears to be tilted left and right. Of course, the onset of the disease occurs in these three aspects, but one aspect can be the main onset. 3, the rotational displacement of the pelvis is the main factor leading to urinary urgency and frequency: due to injury and (or) degeneration, so that the ligament muscles and the joint capsule of the adhesive force is weakened, the pelvis in an inappropriate rotation of the external force, but also can cause the rotational displacement of the pelvis. Due to the misalignment of the sacroiliac joints, the sacrum changes, pulling the pyriformis muscle, resulting in neurovascular compression or irritation in the upper and lower foramina of the pyriformis muscle, clinically appearing as localized oedema, lumbosacral pain, and radiating menstrual pain such as sciatica. In severe cases, the bony nerve, the occlusive nerve and the pubic nerve are compressed, and there is pain in the front of the thigh, the inner side and frequent urination and urgency, and the anus falls down and so on. Urinary frequency and urgency are clinical symptoms that appear when the shadow pubic nerve is stimulated. Some patients urinate 1-2 times per hour or even more. Urinary urgency, sometimes with mild incontinence, for which the patient dares not drink and eat, but the patient does not have urinary pain, and the routine urinalysis is normal. As a result of injury and/or degeneration, the retention of ligament muscles and joint capsule is weakened, and the pelvis is under the action of an inappropriate rotational external force, which can also cause rotational displacement of the pelvis. Due to the misalignment of the sacroiliac joint, the sacrum changes, pulling the pyriformis muscle, resulting in the upper and lower pore of the pyriformis muscle within the neurovascular pressure or stimulation, clinically appear localized oedema, lumbosacral pain as well as sciatica and other radiating menstrual pain: the sciatic nerve in the severe cases, the occlusive nerve and the pubic nerves are compressed, and the front of the thighs, the medial side of the thighs, and the frequency of urination and urgency of urination, and anus falling down, and so on. Urinary frequency and urgency are clinical symptoms that appear when the perineal nerve is stimulated. Some patients urinate 1-2 times per hour or even more. Urinary urgency, sometimes with mild incontinence, for which the patient dares not drink and eat, but the patient does not have urinary pain, and the routine urinalysis is normal. 4.Use the pelvic rotation reset method with a holistic viewpoint. According to the viewpoint that the key to the pathogenesis of lumbar intervertebral disc herniation put forward by Prof. Feng Tianyou is spinal instability, we analyze how lumbar intervertebral disc herniation causes frequent urination from the perspective of spinal and pelvic structural instability (equilibrium); and from the abnormality of gait, we observe whether there are pelvic tilting, lumbar segmental straightening of scoliosis and unequal length of lower limbs, which can be guided by the quantitative measurement of pelvic X-ray for the treatment of manipulation. All of them aim to adjust the mechanical balance, improve the abnormal stress state of the diseased segments, and cure the disease at root. CONCLUSION: Pelvic rotation and repositioning method has a unique effect in the treatment of urinary frequency caused by lumbar disc herniation, which is worth to be widely promoted.
