Symptoms associated with abdominal pressure dysregulation can include back pain, hip pain flank pain (kidney region), bloating, heartburn, vomiting and diarrhoea. The abdominal musculature should fire in response to lower limb movement. Notably the transverse abdominus muscle, but also the obliques, rectus abdominus and lower multifidus (back muscles) are active, ready for lower limb movement (The core). When the transverse muscle doesn’t work with the multifidi muscles then the quadratus lumborum (QL) tries to take over. The QL (a back muscle) is a notoriously overactive muscle in the experience of acute and chronic back and hip pain. The QL can also be found commonly involved in chronic recurrent lower back and or hip pain. Essentially the QL tells us that our core is not functioning well, in particular the automatic readiness of the transverse, obliques, and multifidus muscles to our normal lower limb movement is dysfunctional.
The QL is the help or aka compensation. Treatment to reduce the tightness of the QL is in fact taking away ‘the help’ the body is providing for itself and thus unhelpful in the long run. However such a strategy may be symptomatically relieving in the short term.
