one of the most common undiagnosed and untreated consequences of the pronated foot posture is the effect it will have on sacro-iliac mobility and thereby the effects on the lumbar spine. It is almost certain that this person will have an immobile pair of SIJ's. Returning mobility to this pair of joints is vital to the long term pain relief of pronators. Mobilisation treatments given to lumbar spinal joints to turn off spinal protective responses is just as important , though the effects will of course be felt almost immediately. Time spent mobilising lumbar joints is the most effective you can offer , providing you are willing to go the distance and achieve full mobility with each joint by being persistant. It is not uncommon for those with Lumbar protective responses to take four or five minutes of continuous mobilisation with each joint to achieve a mobile and painfree result.
