Walking one deep and one shallow, should be considered from several aspects, first of all, we should consider the abnormal leg, that is, the leg that walks deep, because there is subsidence, need to judge whether there is hip joint or sacroiliac joint lesion, such as femoral head necrosis, sacroiliac arthritis, not able to tolerate upright pain triggered by uprightness. So it will be evasive down a probe, that is, have to walk a deep, this is a localized problem, need to take the pelvis of the front and side of the film and the femoral head of the flat film, CT in order to make a diagnosis; at the same time, it is necessary to combine with the examination: for example, the four-letter test, pelvic compression test, in order to exclude whether there is a disease of the bone or the sacroiliac joints. Secondly, it is necessary to consider whether there are any muscle and tendon bond problems, which can also be determined by physical examination and radiographs. If the pain is not the cause of the deep and shallow walking, it is important to consider whether there is any walking clumsiness caused by cerebral infarction. General deep sensory impairment, such as the position of the joints, the movement is not controlled by the brain, walking will be different from the normal leg, because when walking, the knee bend and ankle, hip flexion, can not be synchronized with the contralateral side, there will be walking one deep and one shallow. If it is the problem of muscle strength, that is, the problem of muscle power, in the acute stage of cerebral infarction or the after-effects of the stage will also appear this kind of walking one deep and one shallow, need to go to the Department of Neurology, to carry on the examination and take the head of the nuclear magnetic resonance in order to confirm the diagnosis.
