Effects of Extension Biased External Limb Loading in Addition to McKenzie Extension Protocol in Lumbar Derangement Syndrome

Low back pain is one of the most common problem affecting one's daily living activities. McKenzie Method of Mechanical Diagnostic Therapy (MDT) is an appealing modality of treatment. McKenzie classified the lumbar back pain into three categories i.e. lumbar postural syndrome, lumbar dysfunction syndrome and lumbar derangement syndrome. Progressive extension bias limb loading exercises at lumbar region emphasizes on lumbar extensor musculature. The purpose of the current study is to determine the effects of extension biased lumbar limb loading exercises along with McKenzie extension protocols in the management of patients with lumbar derangement syndrome, which will also be a cost effective management option. It will also add to the existing pool of knowledge in the fields of conservative low back pain treatment, physical therapy, orthopedic manual therapy and musculoskeletal medicine.
