SIJ pain is most commonly seen in the pregnant women, however you do not have to be pregnant to develop this type of pain! The SIJs join the lower back to the pelvis. SIJ pain is often one sided and can occur if there is too much or too little movement at this joint. Symptoms of SIJ pain include difficulty standing on one leg, localised pain over the SIJ, muscle tightness and weakness. Physiotherapy management involves soft tissue work, taping or bracing (more common for pregnant women) and strengthening exercises for the muscles around the pelvis.
