Level of Activity in Lumbar Spinal Stenosis Patients Pre- and Post-surgery
Spinal StenosisThe purpose of the proposed research is to explore the relationship between objectively measured physical activity and surgical intervention for lumbar spinal stenosis (LSS). Our primary hypothesis is that post-surgery, LSS patients will demonstrate increased physical activity compared to their baseline assessment. A non-intervention control group will be measured at the same time intervals as the surgical group to look at test re-test reliability. In the event that our hypothesis is rejected, and surgery does not lead to a decrease in sedentary behaviour analysis of questionnaire-based sedentary behaviour measures and objective activity-based measurement can examine the relationship between self-report and actual performance-based objective measures. The primary objective of our proposal is to determine if surgical intervention leads to increased activity, and decreased sedentary behaviour. The findings of the proposed research will inform healthcare stakeholders that if surgery alone does not lead to increased activity, a more concerted research effort may need to be made for post-surgical rehabilitation, lifestyle and physical activity counselling so that post-surgical patients may make changes toward leading more active and productive lives.

The Effectiveness of Oral Corticosteroids in the Treatment of Lumbar Stenosis
Spinal Stenosis of Lumbar RegionThe aim of this study is to evaluate the effectiveness of the use of systemic corticosteroids administered orally in narrow lumbar canal syndrome.

Feasibility Study of NL-Prow Interspinous Spacer to Treat Lumbar Spinal Stenosis
Lumbar Spinal StenosisThe purpose of the study is to evaluate the clinical safety and feasibility of the NL-Prow™ Interspinous Spacer implant and insertion procedure in the treatment of lumbar spinal stenosis

LLIF Plus Posterior Decompression for Severe Lumbar Spinal Stenosis
Lumbar Spine DegenerationLumbar Spinal StenosisLateral lumbar interbody fusion (LLIF), as a minimally invasive technique, is an indirect decompression technique, and its decompression effect is not as thorough as traditional posterior decompression surgery. For certain patients with severe lumbar stenosis, additional posterior decompression is required. However, whether additional posterior decompression is necessary for these patients is unknown. Radiographic predictors of failed indirect decompression via LLIF is unknown. In current randomized, controlled trial , the investigators compare the clinical outcomes of patients with severe lumbar stenosis who received LLIF plus posterior decompression and those without posterior decompression.

Randomized Control Trial of Quadratus Lumborum Block for Lumbar Spine Decompression and Fusion Surgery...
Spinal Stenosis LumbarSpondylolisthesis3 moreLumbar spinal decompression and fusion is a commonly performed procedure fro neural impingement and back pain from a variety of pathologies. The importance of pain control in the postoperative period for spinal surgery has been discussed and proven extensively, with both immediate and delayed reduction in complications and improved clinical results. Quadratus lumborum (QL) block was introduced in 2007 and is performed under ultrasound guidance for perioperative pain management in various surgeries.However, the plane for a posterior QL block can be easily reached during open midline spinal surgery. The investigators hypothesize that the posterior QL block is an effective analgesic tool for lumbar laminectomy surgery, because in lumbar laminectomy the quadratus lumborum is already exposed and is in direct visual contact. For that reason it is imperative to test the benefits of this procedure. This is a double blinded randomized control study to assess the results of intra-operative QL block performed for lumbar decompression and fusion.

Effectiveness and Safety of Korean Medicine for Lumbar Stenosis Patients With Sciatica
Lumbar Spinal StenosisA prospective study investigating the effectiveness and safety in lumbar stenosis patients receiving integrative Korean medicine treatment at 3 locations of Jaseng Hospital of Korean Medicine through assessment of pain, functional disability, and quality of life

Total Facet Arthroplasty System®(TFAS®) Clinical Trial
Spinal StenosisLow Back Pain4 moreThe Archus Total Facet Arthroplasty System® (TFAS®) is a non-fusion spinal implant indicated for treatment of patients with moderate to severe spinal stenosis. TFAS® replaces the diseased facets following surgical removal. TFAS® offers the surgeon new options for treating spinal stenosis patients, enabling a more comprehensive decompression via complete removal of the facets. TFAS® also offers an alternative to rigid spinal fusion fixation enabling intervertebral motion. The clinical trial is intended to demonstrate restoration of stability and sagittal balance to the spine. TFAS® also eliminates the need for painful bone graft harvest from the patient's hip which may be required with fusion procedures.

Steroid Injections Given at the "Level of MRI Pathology" Versus at the "Level of Clinical Symptoms"...
RadiculopathySpinal Stenosis1 morePatients are being asked to participate in a research study because the patients are being treated for low back pain and the patients have decided to have an epidural steroid injection. Low back pain has a tremendous impact on the individual and society. It not only affects the individuals quality of life, it also contributes to lost productivity and increased health care costs. Epidural steroid injections (ESIs) are a common treatment option for many forms of low back pain. They have been used for low back problems since 1952 and are still being used as a non-surgical form of treatment for low back pain. The goal of the injections is reduction of pain, increased quality of life and improved function. This study is being conducted to determine the outcomes of injections given at the "level of MRI Pathology" versus at the "level of clinical symptoms" to see if one is more effective than the other and to learn more about the characteristics of the two different injections.

The Impact of Spinal Manipulation on Leg Movement in Lumbar Spinal Stenosis Patients
Spinal StenosisThe objectives of the proposed research are to quantify the impact on motor performance of a single SM intervention on surgical waitlist patients with degenerative Lumbar Spinal Stenosis (LSS) using a recently established lower extremity movement task: 1) using alterable levels of task difficulty that is resistant to learning and 2) using measurement of movement kinematics.

Effects and Safety of Epidural PDRN vs. Placebo
Spinal Stenosis LumbarThis is a single-center, randomized, double-blind clinical study to assess the clinical application and outcomes with epidural PDRN versus Normal saline injection in patients with spinal stenosis.
