Physiological causes, cerebrovascular disease and spinal cord disease are considered for the unfavorable movement of the right limb. 1. Physiological reasons: for example, long time lying on the right side, local compression for a long time causes poor blood circulation, which can cause unfavorable limb movement, by changing the bad posture, appropriate activities can be improved. 2. Cerebrovascular diseases: for example, cerebral infarction, cerebral hemorrhage can cause hemiplegia, commonly like the left side of the cerebral infarction, usually the right side of the limb activity is unfavorable, through the cranial CT, MRI and so on can be clearly diagnosed. 3. Spinal diseases: for example, spinal tuberculosis, spinal stenosis, vertebral infection can compress the spinal nerves and cause unfavorable movement of one side of the limb. If the right side of the limb activity is not reduced by rest, you need to consult a doctor for further treatment and diagnosis.
