Use of patient-centered function and symptom rating systems in spinal disorders

The criteria for assessing patients with disorders of the lumbar spine have historically been subjective and variable. This situation has led to uncertainty about diagnostic criteria, operative indications, and surgical outcome. In an effort to improve the evaluation process, various patient- centered function and symptom rating systems, including questionnaires and functional tests, have recently been developed. This report reviews several of these rating systems and their role in the assessment of patients with back-related symptoms.
