Walking one deep, one shallow, to be considered from several aspects, first of all, to consider the leg that is not normal, that is, the leg that walks deep, because there is sinking, need to determine whether there is a hip or sacroiliac joint lesion, such as femoral head necrosis, sacroiliac arthritis, not able to tolerate the upright pain caused when upright. So it will be evasive down a tan, that is, have to walk a deep, this is a local problem, need to take the pelvis of the front and side film and femoral head of flat film, CT to make a diagnosis; at the same time to combine with physical examination: such as four-letter test, pelvic pressure pain test, in order to exclude there is no bone or sacroiliac joint disease. The next step is to consider the presence of muscle and tendon problems, which can also be determined by physical examination and radiographs. If the pain does not cause deep and shallow walking, consider whether there is any clumsy walking caused by cerebral infarction. Generally deep sensory impairment, such as the position of joints, movement is not controlled by the brain, walking will have a different feeling from the normal leg, because when walking, knee bending and ankle and hip bending, can not be synchronized with the opposite side, there will be a deep and shallow walking. If it is a problem of muscle strength, this kind of deep and shallow walking can also occur in the acute stage or post-infarction stage of cerebral infarction, and it is necessary to go to the neurology department for physical examination and head MRI to confirm the diagnosis.
