Active clinical trials for "Spinal Diseases"

Observation study about physical activity, motor competence, pulmonary function, and health related quality of life in children, surgically treated for early onset scoliosis

This is a prospective single-institution longitudinal study to access quality of life and serial imaging and biodynamic testing to assess spinal disorders associated with Parkinson's disease patients.

Sarcopenia on lumbar paraspinal muscles is receiving renewed attention as a cause of spinal degeneration. However, there are few studies on the precise concept and diagnostic criteria for spinal sarcopenia. Here, we develop the concept of spinal sarcopenia in community-dwelling healthy elderly people. In addition, we aim to observe the natural aging course of paraspinal muscle and back muscle strength, and investigate the association between conventional sarcopenic indices and spinal sarcopenia. This is a prospective observational cohort study with 120 healthy community-dwelling elderly people for 4 years. All subjects will be recruited according to no sarcopenia, possible sarcopenia, sarcopenia, and severe sarcopenia groups. The primary outcomes of this study are isokinetic back muscle strength and lumbar paraspinal muscle quantity and quality using lumbar spine MRI. Conventional sarcopenic indices and spine specific outcomes such as spinal sagittal balance, back performance scale, and Sorenson test will be also assessed. The data will be analysed using the intention-to-treat principle.

EQ-5D is one of the most commonly employed patient-reported outcome (PRO) measures. It is included in many of the Swedish National Quality Registers (NQRs). EQ-5D health states are usually summarized using 'values' obtained from healthy members of the general public. However an alternative - which remains to be studied in detail - is the potential to use patients' self-reported overall health on the visual analogue scale as a means of capturing experience-based values. The overall aim of this project is to increase knowledge on the potential applicability of EQ VAS as a health state valuation method through assessment of its variability across and within patient groups and compared with that of the general population in Sweden. Data on nearly 700,000 patients from 12 NQRs covering a variety of diseases/conditions and from the general population will be analysed. Longitudinal studies of PROs among different patient groups will be conducted at baseline/first visit and 1-year follow-up. Descriptive analyses comparing EQ-5D health states and observed self-assessed EQ VAS within and across registers will be performed. Comparisons of the change in health state and observed EQ VAS values over one year will also be made. Regression models will be used to assess whether EQ-5D dimensions predict observed EQ VAS values to investigate patient value sets in each NQR. These will be compared across the patient groups and with the existing Swedish experience-based VAS and time trade-off (TTO) value sets obtained from the general population. This research project will provide information on the variation among different patient groups in terms of self-reported health status through EQ VAS and comparison with the general population. Knowledge on the relative importance of different dimensions of the EQ-5D to different patient groups as well as the general population will be gained in this project. The possibility of getting value sets based on patients' self-reported EQ VAS values and their comparison with value sets from experience-based general population studies will be discussed.

The purpose of this study is to report the radiographic, clinical, and functional outcomes of a consecutive series of patients diagnosed with single or bilateral degenerative disc disease between L4 and S1, that have been treated with an anterior lumbar interbody fusion (ALIF), anterior only surgical approach, and InQu Bone Graft Extender and Substitute for bony fusion and instrumentation. Patients that decide to undergo an Anterior Lumbar Interbody Fusion (ALIF) surgery [a surgical procedure that joins two or more lumbar vertebrae (small bones of the spine) together into one solid bony structure by approaching the spine through the abdomen (front of the body) and placing a bone graft in between the vertebral bodies where the disc usually lies], are invited to participate in an orthopaedic research study. This study will compare patients that have been treated with an anterior lumbar interbody fusion using InQu Bone Graft Extender & Substitute to published data for a stand alone spinal fusion surgery, where InFuse bone graft is placed between the transverse processes [small bony projections off the right and left side of each bone in your spine] of the affected vertebrae. X-rays, daily activities, and how patients are doing will be evaluated at specific time points during this study. The hypothesis of this study is that patients diagnosed with degenerative disc disease treated with an anterior lumbar interbody fusion, anterior only surgical approach (incision through the abdomen), using InQu Bone Graft Extender and Substitute and instrumented fixation have comparable radiographic (x-rays), functional (daily activities), and clinical (how the patient is doing) outcomes when compared to published data for use of InFuse in stand-alone fusion.

In patients undergoing spine surgery, spinal nerve roots and spinal cord are vulnerable to surgical insults especially for instrumentation and may lead to long term sequelae. The incidence of clinical peripheral neuropathy after cervical spine surgery has been reported up to 30%. Intraoperatively, spinal cord and nerves function can be monitored using electromyography (EMG) and somatosensory evoked potentials (SSEP) and thereby, intervention can be made to potentially reduce the incidence of adverse neurological sequelae. However, conventional EMG and SSEP monitoring requires presence of a trained EP technician, use of needle electrodes and currently bulky EP equipment and is thus not practical for routine clinical usage. In this study, the invesitgators will assess the clinical feasibility of using a novel miniaturized and automated EMG/SSEP device (EPAD® 2.0) in spine surgical patients.

Specific aims of this project were as follows: To investigate the eye-head coordination of patients with cervical spine degeneration. To investigate the relationship of these impairment measurements (range of motion, muscle power, proprioception, sensory threshold, eye-head coordination) and functional outcome (neck disability index, quality of life evaluation). To develop a computer assistant device and software for the proprioceptive training and eye-head coordination. To provide a treatment and prevention program emphasized on proprioception treatment and coordination for employee with neck-shoulder complaints.

Introduction: With the increase of the elderly population, the number of elderly patients undergoing surgery is increasing, and postoperative delirium is 11-51% depending on the type of surgery. In recent cohort studies have shown that delirium might reduce cognitive function and develop dementia. Since delirium is difficult to treat, the key to treatment is prevention, and about 40% is prevented when prophylactic intervention is applied. However, delirium is difficult to diagnose and difficult to predict, therefore, biomarkers are needed to diagnose and prevention. Exosome and brain efficiency test(electroencephalogram, and pulse wave test) have the potential of simple biomarkers that can diagnose postoperative delirium and predict cognitive decline. Purpose: The purpose of this study is to investigate the risk factors affecting delirium in the elderly who have spinal surgery and to search for biomarkers of delirium for early detection and prevention of delirium.

A retrospective parallel group comparison study to support expansion of the indication of the company's FDA approved Spinalogic™ device to include the cervical spine. The SpinalogicTM device was initially approved by FDA as an adjunct to one- or two-level lumbar fusion (P910066/S011). It is a non-invasive bone growth stimulator (BGS) that generates a combined magnetic field (CMF) that has been proven to accelerate bone healing and fusion in the lumbar spine.

This study aims to: describe the monitoring of patients treated for spinal disorders. create a comprehensive database of reliable and readily exploitable quickly to produce a library of cross publications between orthopedic surgery and neurosurgical services. This database will include clinical, functional , radiographic , educational, social and professional data. obtain a cohort of patients in the comprehensive range of spinal pathologies. standardize data collection in this cohort with similar national projects.
