What is the muscle imbalance pattern for sciatica

Sciatica muscle imbalance is a diagnosis often made by chiropractors and physical therapists to explain sciatic nerve pain which is not caused by the usual suspect spinal abnormalities. Since the muscles involved are not spinally-located, the expression produced should actually be called pseudo-sciatica, since true sciatica is defined as pain which is sourced within the vertebral column exclusively.
