Evaluating lateral mobility of the hip, pelvis and lower spine seems to be a relevant thing. If the pelvic girdle cannot move in one direction, it will move in another. Long ago i noted a subtle form of lack of lateral pelvic mobility which I named a pelvic side glide dysfunction. It can be observed in stance and gait at times, but many times it is too subtle and yet is very apparent when client is supine and passive force is applied to the lateral pelvic to induce left to right side glide andcomparing to the opposite direction. One first takes up the slack and then induces an additional impulse. Gentle passive stretching for 5 minutes is usually sufficient, done in sidelying over a few pillows. I suspect that what you describe may be a lack of available side glide mobility which then induces the lumbo-pelvic-hip region to take an alternate route. I agree thatassymmetry of pelvic landmarks does NOT mean the the ilium has rotated on the sacrum or the reverse of that. A person with fused SI joints can still move in that manner, the pelvis moving on both femoral heads. Our profession is very young and yes we have some research and yes we need so much more. I encourage your efforts and look forward to hearing more. who is OIG?
