Filter by:Opioid overdose suppresses brainstem respiratory circuits, causes apnea, and may result in death. Epidural electrical stimulation (EES) at the cervical spinal cord facilitated motor activity in rodents and humans, and we hypothesized that EES of the cervical spinal cord could antagonize opioid-induced respiratory depression in humans. In this study, we will stimulate the spinal cord during surgery and assess its effects on respiratory function in human patients.
In this study we are investigating whether there is a relationship between the lordosis angle measured on cervical X-RAY images on the severity and level of cervical disc herniation detected by cervical MRI, demographic characteristics and the duration and posture of the person's daily life activities.
Study Purpose: This study is intended to monitor outcomes for 1 year following cervical TFESI. Based on current clinic volume and enrollment rates into a current study of cervical epidural injections that is nearing completion, we conservatively estimate a study enrollment period of 18 months and a total period of 2.5 years from enrollment to final follow-up data collection. If the study were to theoretically start enrolling in July 2019, we would anticipate completion by February 2022. Objectives: 1. Determine the proportion of patients with an 80% or greater improvement in arm and neck numerical rating scale pain (NRS) score following an initial cervical transforaminal steroid injection (TFESI) at 4 weeks post-injection and the duration of response up to 12 months. 2. Determine the proportion of patients with a 50%-79% improvement in arm and neck NRS score following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 3. Determine the proportion of patients with less than 50% improvement in arm and neck NRS score following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 4. Determine the proportion of patients with an initial injection plus up to 3 additional injections that maintain 80% or greater, as well as 50-79%, improvement in arm and neck NRS score for up to 12 months. 5. Determine the proportion of patients with a clinically significant change in function defined by a minimally clinically significant change (MCIC) (≥10 point improvement ) or 30% improvement in Neck Disability Index (NDI) score following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 6. Determine the proportion of patients with clinically significant improvement in the Medication Quantification Scale (MQS III) score (≥6.8 point change , equivalent to 10 oral morphine equivalents ) following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 6. Determine the proportion of patients with clinically significant improvement in the categorical EuroQol 5 Dimensions tool (EQ-5D) defined by ≥0.03 following an initial cervical TFESI at 4 weeks post-injection and the duration of response up to 12 months. 7. Compare patient demographic, clinical, and imaging characteristics between response groups and perform predictive modeling to better understand variables that increase the likelihood of a successful clinical outcome. 8. Report adverse effects.
The basic purpose of current research is to evaluate the comparative effectiveness of therapeutic exercises and educational sessions after microdiscectomy through Minimally Invasive Surgery for disc herniation. A Randomized trial will be conducted on 60 patients from Ghurki hospital , divided into two groups. Simple random sampling will be utilized as sampling strategy. Assessment of physical activities of daily living and quality of life will be performed before and after 8 weeks of post intervention surgery through Oswestry Disability Index, Physical activity survey , SF 36 and Subjective Quality of Life scale respectively . A follow up assessment will be performed after 6 months. Analysis will be done through SPSS 21.
The primary endpoints of the investigation will include assessment of the maintenance of disc height demonstrated by radiographic evidence based on plain radiographs and MRI and relief of pain as measured by Visual Analog Scale (VAS) at six months post-surgery. It is anticipated that outcomes with the InterCushion Disc Nucleus Prosthesis (DNP) will be comparable to or better than the historical published results for discectomy alone.
To evaluate the safety and effectiveness of the AO-1000 device to treat and relieve the pain of symptomatic subjects with contained herniated discs. This single-arm pilot study will be used as a go vs. no-go decision on performing a randomized-controlled trial. The study's primary effectiveness objective is to demonstrate that the patient's functionality (based on Oswestry Disability Index scores) has improved from baseline at one month. The study's primary safety objective is to demonstrate that serious device/procedure related adverse events and subsequent surgical interventions are no greater than those in a literature control of other percutaneous disc decompression procedures at discharge, 1 month, 6 months, and 12 months post-treatment. Secondary objectives are to demonstrate procedural success and improvement in the pain and function of the subjects at 1, 6, and 12 months using the VAS and ODI scales as well as tracking analgesic medication use. Pain and function scores for each follow-up time will be compared to the baseline scores.
