<unk>  (NC), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord.<unk>  means that the problem originates within the nervous system.<unk> , from the Latin word for to limp, refers to painful cramping or weakness in the legs. should therefore be distinguished from vascular<unk> , which stems from a circulatory problem rather than a neural one. The term<unk>  is sometimes used interchangeably with spinal stenosis. However, the former is a clinical term, while the latter more specifically describes the condition of spinal narrowing. is a medical condition most commonly caused by damage and compression to the lower spinal nerve roots. It is a neurological and orthopedic condition that affects the motor nervous system of the body, specifically, the lower back, legs, hips and glutes. does not occur by itself, but rather, is associated with other underlying spinal or neurological conditions such as spinal stenosis or abnormalities and degenerative changes in the spine. The International Association for the Study of Pain defines<unk>  as, "pain from intermittent compression and/or ischemia of a single or multiple nerve roots within an intervertebral foramen or the central spinal canal. This definition reflects the current hypotheses for the pathophysiology of , which is thought to be related to the compression of lumbosacral nerve roots by surrounding structures, such as hypertrophied facet joints or ligamentum flavum, bone spurs, scar tissue, and bulging or herniated discs. The predominant symptoms of involve one or both legs and usually presents as some combination of tingling, cramping discomfort, pain, numbness, or weakness in the lower back, calves, glutes, and/or thighs and is precipitated by walking and prolonged standing. However, the symptoms vary depending on the severity and cause of the condition. Lighter symptoms include pain or heaviness in the legs, hips, glutes and lower back, post-exercise. Mild to severe symptoms include prolonged constant pain, tiredness and discomfort in the lower half of the body. In severe cases, impaired motor function and ability in the lower body can be observed, and bowel or bladder dysfunction may be present. Classically, the symptoms and pain of are relieved by a change in position or flexion of the waist. Therefore, patients with have less disability in climbing steps, pushing carts, and cycling. Treatment options for depends on the severity and cause of the condition, and may be nonsurgical or surgical. Nonsurgical interventions include drugs, physical therapy, and spinal injections. Spinal decompression is the main surgical intervention and is the most common back surgery in patients over 65. Other forms of surgical procedures include: laminectomy, microdiscectomy and laminoplasty. Patients with minor symptoms are usually advised to undergo physical therapy, such as stretching and strengthening exercises. In patients with more severe symptoms, medications such as pain relievers and steroids are prescribed in conjunction with physical therapy. Surgical treatments are predominantly used to relieve pressure on the spinal nerve roots and are used when nonsurgical interventions are ineffective or show no effective progress. Diagnosis of<unk>  is based on typical clinical features, the physical exam, and findings of spinal stenosis on Computer Tomography (CT) or X-Ray imaging. In addition to vascular<unk> , diseases affecting the spine and musculoskeletal system should be considered in the differential diagnosis.
