For patients with sacroiliac arthritis, the most basic thing to do is to control body weight to radically reduce the weight on the sacroiliac joint; secondly, to pay attention to the posture of activities, avoid bending over to lift heavy objects and should lift heavy objects with both legs flexed, otherwise it is easy to cause wear and tear on the sacroiliac joint. Finally, one should take the initiative to exercise muscle strength to avoid muscle atrophy. One can engage in sports activities such as swimming and running to increase the stability of the spine and sacroiliac joints to avoid joint wear and tear. Patients who already suffer from sacroiliac arthritis should preferably move around with the protection of a lumbar support.
