A normal anterior-to-posterior (AP) diameter of the spinal canal is somewhere between 22-25mm. In relative LSS, this diameter has narrowed down to 10-12mm. This presentation is often asymptomatic. Absolute LSS shows a spinal canal with an AP diameter of less than 10mm and is often symptomatic.\r\nLSS can also be classified according to its anatomy. LSS can be monosegmental or multisegmental, and unilateral or bilateral and occur centrally, laterally in the recess or the intervertebral foramen (<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/19578346\" target=\"_blank\" rel=\"noopener noreferrer\">Siebert et al. 2009<\/a>). In this post, we will focus on central canal stenosis, which can lead to neurogenic claudication by a compression of the cauda equina. So when we talk about LSS in the following we are referring to the central canal.\r\n\r\nLateral recess stenosis and interforaminal stenosis will have different signs &amp; symptoms. In these instances, not the myelum, but the spinal nerve roots are compressed leading to lumbosacral radicular syndrome (see previous unit). While in lateral stenosis, the patient typically complains of severe radiating pain during the day that keeps him up at night, foraminal stenosis is influenced by the position of the spine. Lumbar flexion leads to an average of 12% increase in the foraminal area and thus decreases radicular symptoms, while lumbar extension decreases the foraminal area by 15%, which leads to an aggravation of pain and radiculopathy. <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/10703115\" target=\"_blank\" rel=\"noopener noreferrer\">Jenis et al. (2000)<\/a> describe that the most common roots involved were L5 (75%), followed by L4 (15%), L3 with 5.3%, and L2 with 4%. The distribution of prevalence is explained by the relation between the size of the foramen and the nerve root\/dorsal root ganglia (DRG) cross-sectional areas. The lower lumbar and sacral roots and DRG are larger in diameter, leading to a smaller foramen-to-root ratio. On top of that, the highest static and dynamic compression take place at segments L4\/L5 and L5\/S1.\r\n\r\nMultiple factors can contribute to the development of spinal stenosis, and these can act synergistically to exacerbate the condition (<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/19578346\" target=\"_blank\" rel=\"noopener noreferrer\">Siebert et al. 2009<\/a>):\r\n<ul>\r\n \t<li>Degeneration of the vertebral disc often causes a protrusion, which leads to ventral narrowing of the spinal canal<\/li>\r\n \t<li>As a consequence of disc degeneration, the height of the intervertebral space is further reduced, which causes\u00a0the recess and the intervertebral foramina to narrow, exerting strain on the facet joints<\/li>\r\n \t<li>Such an increase in load can lead to facet joint arthrosis, hypertrophy of the joint capsules and the development of expanding joint cysts (lateral stenosis)<\/li>\r\n \t<li>The reduced height of the segment causes the ligamenta flava to form creases, which exert pressure on the spinal dura\u00a0from the dorsal side (central stenosis)<\/li>\r\n \t<li>Concomitant instability due to loosened tendons (e.g. the ligamenta flava) further propagates preexisting hypertrophic changes in the soft tissue and osteophytes, creating the characteristic trefoil-shaped narrowing of the central canal<\/li>\r\n<\/ul>\r\n&nbsp;\r\n\r\n<em><strong>Epidemiology<\/strong><\/em>\r\n\r\nThe annual incidence of LSS is 5 in 100.000 individuals, which is fourfold the incidence of stenosis occurring in the cervical spine.

They found a pooled prevalence of 11% of clinical symptoms of LSS in the general population with a mean age of 62. In patients in a primary care setting with a mean age of 69, this number rose to 25% and even 39% in secondary care and a mean age of 58.\r\nThe authors also found that 11% of healthy subjects with a mean age of 45 and 38% in general populations with a mean age of 53 had a radiological diagnosis of LSS.

The back pain is localized in the lumbar spine and can radiate towards the gluteal region, groin, and legs, frequently displaying a pseudoradicular pattern (see our unit on aspecific low back pain). Due to neurogenic claudication, leg symptoms can include fatigue, cramps, heaviness, weakness and\/or paresthesia, ataxia, and nocturnal leg cramps (<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/19578346\" target=\"_blank\" rel=\"noopener noreferrer\">Siebert et al. 2009<\/a>).\r\n<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/23385136\" target=\"_blank\" rel=\"noopener noreferrer\">De Schepper et al.

(1989)<\/a>. With a sensitivity of 63% and a specificity of 80%, this test is moderately useful to confirm, but not to exclude lumbar spinal stenosis. To conduct the test, have a patient walk on a treadmill at a speed of 1.8km\/h and a maximum walking time of 15 minutes but shortened according to the symptoms of the tested person. The rear end of the treadmill is elevated to create a 10-degree downward slope in the walking direction to exaggerate the lumbar lordosis of the tested subject. This diminishes the square area of the spinal canal. The test is considered positive if a \u201csymptom-march\u201d is exhibited which means that the patient reports discomfort during the activity with an extension of symptoms into the lower extremities.\r\n<div class=\"embed-container\">\r\n\r\n[embed] https:\/\/www.youtube.com\/watch?v=y8can7nQFdc[\/embed]\r\n\r\n<\/div>\r\nIn case you suspect foraminal stenosis in your patient, Kemps Test can help you to decrease the interforaminal area and entrap the nerve, thus provoking symptoms.

(2013)<\/a> have compared individual signs &amp; symptoms regarding their ability to distinguish between the 2 conditions. They found that pain alleviators and symptom location had weak clinical significance for neurogenic claudication and vascular claudication. The most distinguishing features of a neurogenic origin were:\r\n<ul>\r\n \t<li>A positive shopping cart sign<\/li>\r\n \t<li>Symptoms located above the knees<\/li>\r\n \t<li>Provocation with standing and relief with sitting had a strong likelihood.<\/li>\r\n<\/ul>\r\nCombining those features yielded a positive likelihood ratio of 13. Patients with symptoms in the calf that were relieved with standing had a strong likelihood of vascular claudication (LR+ 20).\r\n\r\nBe aware, that there can be other underlying reasons for nerve root entrapment than a herniated disk. On top of that, pain radiating to the proximal leg could also be referred pain instead of radicular pain.

Additionally, exercise was able to reduce depression, anger, and mood disturbance among patients with LSS. Further research suggests that a supervised exercise program is superior to a home-exercise program and that exercising twice a week yields superior outcomes compared to only once a week (<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/30986577\" target=\"_blank\" rel=\"noopener noreferrer\">Minemata 2019a<\/a><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/30202267\" target=\"_blank\" rel=\"noopener noreferrer\">, <\/a><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/31842106\" target=\"_blank\" rel=\"noopener noreferrer\">Minemata 2019b<\/a><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/30202267\" target=\"_blank\" rel=\"noopener noreferrer\">). <\/a><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/23886845\" target=\"_blank\" rel=\"noopener noreferrer\">Macedo et al.

While a forward-flexed posture might not be desirable from a cosmetic point-of-view, patients and their spouses should understand that this posture is beneficial in order to decrease pressure on the cauda equina and spinal nerves. An RCT by <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/24098633\" target=\"_blank\" rel=\"noopener noreferrer\">Comer et al. (2019)<\/a> then also found that a physiotherapist-described home exercise program is not more effective than advice and education.

In 74% of patients with a directional preference, they found that exercises matching subjects' DP significantly and rapidly decreased pain and medication use and improved all other outcomes compared to the non-matched group.\r\n\r\n<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/28713037\/\" target=\"_blank\" rel=\"noopener\">Longtin et al. (2018)<\/a> examined if patients with LSS have a directional preference for flexion direction exclusively. They found that a high proportion of patients with LSS presented a directional preference (88.9%), which confirms the mechanical aspect of this type of low back pain.\u00a0 Not surprisingly most patients with LSS in the study, about 80% (19\/24), had a DP in flexion (repeated lumbar flexion exercises reduced their symptoms). These results support the theoretical biomechanical principle: by augmenting the spinal canal lumen via flexion of the lumbar spine, flexion-based exercises may alleviate the symptoms of LSS by decreasing \u201cpressure\u201d on the spinal structures. They also provide evidence in part for why clinicians often use flexion-based treatments without further investigation when treating patients with signs of LSS, because most of the time, patients do obtain pain relief with lumbar flexion.\r\n<div class=\"embed-container\">\r\n\r\n[embed]https:\/\/www.youtube.com\/watch?v=ShM14BoX2WE[\/embed]\r\n\r\nSimilar to direction-specific exercises, passive lumbar mobilization can help to relieve symptoms in LSS,\u00a0 but also foraminal stenosis on short-term:\r\n<div class=\"embed-container\">\r\n\r\n[embed]https:\/\/www.youtube.com\/watch?v=q8cItxkIOQ4[\/embed]\r\n\r\n<\/div>\r\nPassive hip mobilization into extension is a way to decrease hip stiffness and to thus increase hip extension range of motion<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/12622484\/\" target=\"_blank\" rel=\"noopener\"> (Whitman et al. 2003)<\/a>.

These cases are often referred for surgery and LSS is the number 1 reason for surgery in the elderly (<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/19578346\" target=\"_blank\" rel=\"noopener noreferrer\">Siebert et al. 2009<\/a>).

They concluded that at 2 years, the outcomes except for the change in physical function score in the ZCQ subscale did not differ significantly between patients who had undergone surgery and those who avoided surgery.\r\nOn the other hand, a recent study by\u00a0<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/30952135\" target=\"_blank\" rel=\"noopener noreferrer\">Held et al. (2019)<\/a> showed that patients with nonoperative treatment had lower quality of life and function compared to patients undergoing surgery at the 12-month follow-up. So if a patient suffers for a long time and conservative therapy does not show the desired results, surgery might be indicated.\r\n\r\nWhat other factors might determine who could benefit from surgery? <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/30511244\" target=\"_blank\" rel=\"noopener noreferrer\">Iderberg et al. (2019)<\/a> have examined which factors determine success after surgery and found that the following factors predicted good function: being born in the EU, reporting no back pain at baseline, having a high disposable income, and having a high educational level. On the other hand, factors predicting a worse outcome were previous surgery, having had back pain for more than 2 years, having comorbidities, being a smoker, being on social welfare, and being unemployed.\r\n\r\n&nbsp;\r\n<h3><strong>References<\/strong><\/h3>\r\n<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24098633\/\" target=\"_blank\" rel=\"noopener\">Comer, C., Redmond, A.
