Prediction of Back Disability in Adults With Low Back Pain

Low back pain (LBP) is one of the most enormous and challenging disorders. LBP represents a leading cause of disability worldwide. A number of variables (clinical, functional and mechanical) may predispose to back disability. Clinical variables such as pain may affect the patient ability to move and also may result in muscle spasm that led to more pain and movement restriction. Further, functional capabilities may affect the patient and when reduced may lead to disability. Moreover, biomechanical factors such as abnormal posture creates abnormal stress and strain in many spinal structures which are considered predisposing factors for pain and disability. There is a gab of evidence to examine the relationships between those variables and to predict disability in patients with chronic nonspecific low back pain using various variables.
