Lumbar spinal stenosis (LSS) refers to a spinal canal narrowing compressing the spinal cord and its nerves at the level of the lumbar vertebra. Symptoms include leg weakness, back pain, and rarely sphincter dysfunction. Some patients are asymptomatic. This constellation of symptoms may also be identified in elderly with different conditions rather than LSS. Consequently clinical suspected LSS should be confirmed by a diagnostic exam. Unfortunately there is no single test that strongly defines LSS diagnosis. LSS diagnosis is made through a complete assessment that combines history, physical exam, neurophysiology and imaging. Magnetic resonance imaging (MRI) is used as the preferred imaging test for assessing the stenosis ], but it is not used as a screening tool and it does not evaluate nerve function. Despite advances in the clinical understanding of LSS and improvements in imaging techniques, it occasionally remains difficult to diagnose this disorder. Nervous system is being affected by the stenosis (spine, nerves or both). For this reason the aim of this study is to identify the role of neurophysiology study on LSS.
