Lumbar paraspinal muscle dysfunction and low back pain are strongly correlated. Muscle atrophy is common in LBP and is recognised by MRI scan. Corticosteroid injections and physical rehabilitation programs are advocated for treatment of LBP. The purpose is to evaluate efficacy of specific lumbar multifidus muscle retraining exercises and perifacet multifidus injections in treatment of Low Back Pain (LBP) and referred leg pain. 63 patients with non-specific LBP, with or without leg pain, were randomised to three treatment groups. MR images of paraspinal muscle and the atrophy classified. A-Control group, standard physiotherapy for 10 weeks. B-Multifidus rehabilitation program for 10 weeks. C-Perifacet injection (multifidus injection) with methylprednisolone. ODI was primary outcome measure and the SF-36, modified Zung Depression Index and others were secondary outcome measures.Purpose
