I am giving a presentaion on this subject this week end in Bellevue WA. Rotoscoliosis is often misunderstood since there is a differring of opinions on its cause. The most common cause is that the psoas is in a guarding response. This causes a torque or twist force to the spine. The psoas is most often in the guarding response due to a contralateral problem that is missed by most. The groin pull on the contralateral side causes a pull to approximate the symphysis pubis (left most common) which creates a feedback to the proprioceptive sense to activate the contralateral psoas ( right most common) The psoas then applies a rotary pressure to the spine and the QL on the contralateral side to the psoas and the serratus pos. inf. of the ipsilateral side brace the back with a resulting lateral scoliotic patterning. You might show this to your physio. Or contact me.
