Filter by:This single-group cross-sectional cohort study will enroll approximately 25 patients at the North Texas VA Health Care System (VANTHCS) who have previously received off-label prescriptions of misoprostol for lumbar spinal stenosis for any duration and who are willing to provide verbal and informed consent. Patients will answer a questionnaire regarding pain and functional improvement especially in reference to misoprostol treatment. Patients will also be selected to have their walking tolerance (claudication distance) measured in an outpatient clinic setting to determine the severity of their lumbar spinal stenosis symptoms after having received misoprostol.
There is a critical need to target physical activity during postoperative management to optimize long-term recovery after lumbar spine surgery. The overall objective of this study is to conduct a two-group randomized control trial (RCT) to examine the feasibility and acceptability of a physical activity telehealth intervention delivered by a physical therapist for improving disability, physical function, pain, and physical activity compared to usual care after spine surgery for a degenerative lumbar condition. The physical activity intervention will include wearable technology and remote physical therapist support to counsel patients on a realistic progression of physical activity (steps per day). The central hypothesis is that this 8-week physical activity intervention performed at two weeks after surgery will be feasible and acceptable. The results of our randomized trial will be used to support a large multi-site clinical trial to test the effectiveness and implementation of this intervention
High blood pressure is a serious and common health problem. This disease affects 1 billion people all over the world and responsible for 7,1 million deaths. Trials involving more than 1 million people state that stroke incidence rises as blood pressure rises. The effects of high blood pressure on cerebral perfusion is not well realized. Intraoperative blood pressure management of patients with high blood pressure is not well known. And it is still not clear how autoregulation of cerebral perfusion is affected by high blood pressure. Systemic arterial pressure changes have little effect on cerebral perfusion. This is regulated by changes of precapillary resistance. When systemic arterial blood pressure drops, it is regulated by vasodilatation of arteriolar smooth muscles. And when systemic blood pressure rises, it is regulated by vasoconstriction of arterioles. Cerebral perfusion is well preserved between 50-125 mmHg changes of mean arterial blood pressure (MAP). Patients with high blood pressure have higher ranges. Patients with chronic high blood pressure can better tolerate higher blood pressures. But even physiologic drops of systemic blood pressure can cause ischemia. Anesthetic drugs have variable effects on cerebral blood flow and physiology. The drugs used with anesthetic drugs, the noxious stimulus of surgery, intracranial compliance, blood pressure, and carbon dioxide pressure can all alter and complicate these effects. Anesthetic drugs must be selected carefully in patients with high blood pressure. It is still investigated whether, management of blood pressure under anesthesia, should be individualized. For patients with high blood pressure, some neuromonitorization technics have been evaluated to prevent neurologic complications under anesthesia. But there is not a technic, which is considered as a gold standard. Cerebral blood pressure has been studied by, nitrous oxide method, krypton uptake method, and xenon injection methods previously. Near-infrared spectroscopy (NIRS) is the best monitorization technic of intracranial pressure (ICP), cerebral blood flow (CBF), and cerebral metabolism. But it can not be applied to all patients. Recently, it is possible to measure blood flow of cerebrum with transcranial Doppler ultrasound in anesthesia practice. In this trial, the investigators aim to evaluate cerebral perfusion of hypertensive patients with transcranial Doppler during lumbar disc surgery to optimize the blood pressure under anesthesia. To best of our knowledge, there is no trial evaluating cerebral perfusion of hypertensive patients with transcranial Doppler ultrasound.

The aim of this study was to determine the Turkish validity and reliability of Lumbar Spine Surgery Expectations Survey developed by Mancuso.
Rationale: Cervical degenerative disc disease (CDDD) is a common cause of cervical radiculopathy, myelopathy or myeloradiculopathy. Surgical treatment is indicated when conservative therapies do not provide sufficient relief or when neurological complaints are progressive. The main surgical techniques are anterior cervical discectomy with (ACDF) or without fusion (ACD), whereas both techniques result in high fusion rates. Short term outcomes of surgery show good clinical results. Long term follow-up shows a drop-in satisfaction rates, often due to the occurrence of new complaints. Pathology is often located at levels adjacent to the previously operated segment, known as adjacent segment disease (ASDis). This is thought to be the results of loss of motion at the previously operated and fused segment. Anterior cervical discectomy with arthroplasty (ACDA) is developed in an effort to reduce the incidence of ASDis by preserving physiological motion in the operated segment. Objective: To investigate physiological motion of the cervical spine the investigators will analyze motion patterns at the long-term in patients who underwent surgical treatment for CDDD, either ACD or ACDA. Study design: Fundamental research. This is a prospective study that includes a cohort of patients previously operated in the setting of a randomized controlled trial. Study population: Adult patients with an indication of surgical treatment for cervical radiculopathy as a consequence of CDDD were enrolled in an RCT between 2007 and 2014 and assigned to undergo ACD or ACDA. Flexion and extension cinematographic recordings of the cervical spine were performed, with the last one at one-year follow-up. The majority of patients in the ACDA group (80%) showed a normal sequence of segmental contribution, which was not the case in the ACD group. This cohort will now be asked to participate in the long-term follow-up study assessing the motion patterns 6-13 years after ACD or ACDA surgery. Intervention: One flexion and extension cinematographic recording of the cervical spine and will be made. Main study parameters/endpoints: The sequence of segmental contributions in sagittal rotation during flexion and extension of the cervical spine will be assessed in the long-term follow-up of surgical treatment. Secondary outcomes will be to assess the amount of degeneration based on the Kellgren Score (KS) and the segmental range of motion (sROM). Long term clinical outcomes will be assessed according to VAS, NDI, SF-36 and Odom's criteria. Patients will be asked whether they have new neurological symptoms and whether they have had a re-operation. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participants receive cinematographic recordings once. The amount of radiation is a negligible risk. There will be no health benefits. There will be no follow-up.
The purpose of this study is to evaluate a Zhineng Qigong intervention for patients with chronic low back pain and/or leg pain, and to test feasibility aspects.
Prospective study, not randomised, non-interventional, monocentric, investigating an intended patient cohort of 60 patients already operated on the cervical spine due to degenerative disc disease of the cervical spine down to the first thoracolumbar VBR (C2-T1), who received a Quintex plate for stabilisation
This study is to evaluate the correlation between muscle atrophy (MA), sagittal alignment, and stenosis degree in patients with lumbar spinal Stenosis (LSS). From existing radiological images, specific radiographic parameters will be extracted. General Information (Age, sex, levels of stenosis, duration of symptoms) will be extracted from patient files.
The purpose of this study is to reveal the effectiveness and safety of integrative Korean medicine for spinal stenosis by observation inpatients treated with integrative Korean medicine.
