The Effect of Physiotherapy on Respiratory Function and Psychosocial Status in Lumbar Discopathy

The aim of this study is to investigate the effects of physiotherapy on pulmonary function tests and psychosocial status in patients with lumbar discopathy. Participants undergo a 15-session physiotherapy program. Respiratory function tests and questionnaires, including the Visual Analogue Scale (VAS) for pain, Short Form-36 (SF-36), and Roland Morris Disability Questionnaire (RMQ), are performed before and after the physiotherapy program to evaluate the outcomes.

Lower Back Muscle Size and Recovery After Lumbar Disc Herniation Surgery

Recovery after surgery for a herniated disc in the lower back differs from person to person. The size of the muscles around the lower spine may be related to recovery, but this relationship is not well understood. The purpose of this observational study is to determine whether the size of two lower-back muscles, the psoas and multifidus muscles, measured on magnetic resonance imaging (MRI) scans obtained before surgery is related to recovery after surgery. The study will include 100 adults aged 18 to 75 years who are scheduled for elective surgery for lumbar disc herniation. Participants will receive their usual anesthesia, surgery, and postoperative care. The study will not require any additional imaging, blood tests, medicines, or procedures. Researchers will use each participant's existing preoperative lumbar MRI scan to measure the psoas and multifidus muscles. Participants will complete the 15-item Quality of Recovery questionnaire (QoR-15) before surgery and again 24 hours, 48 hours, and 7 days after surgery. Researchers will also collect information routinely recorded during care, including pain scores, pain medicine use, nausea and vomiting, time spent in the recovery unit, time to first walking, and length of hospital stay. The primary objective is to determine whether preoperative psoas muscle index and multifidus muscle cross-sectional area are independently associated with postoperative Quality of Recovery-15 (QoR-15) scores 24 hours after lumbar disc herniation surgery.

Comparison of 5 vs 8 cmH₂O PEEP on Respiratory Mechanics in Prone Lumbar Surgery

This randomized controlled clinical trial aims to compare the effects of two different positive end-expiratory pressure (PEEP) levels (5 cmH₂O and 8 cmH₂O) on respiratory mechanics in patients undergoing lumbar spine surgery in the prone position under total intravenous anesthesia (TIVA). Prone positioning may adversely affect lung compliance and gas exchange, making optimal ventilatory strategies essential. Driving pressure and mechanical power are considered key determinants of ventilator-induced lung stress. This study will evaluate the impact of different PEEP levels on respiratory parameters and intraoperative physiological changes.

Comparison of TLIP Block and QIP Block for Postoperative Analgesia After Lumbar Spine Surgery

This study compares two regional anesthesia techniques used for pain control after lumbar spine surgery: the classic thoracolumbar interfascial plane (TLIP) block and the quadratus lumborum-iliac plane (QIP) block. Patients between 18 and 65 years of age who undergo elective lumbar discectomy (up to two spinal levels) will be observed based on which block their treating anesthesiologist chooses to use as part of routine clinical practice. No randomization or additional intervention beyond standard care will be performed. Researchers will record the total amount of opioid pain medication used in the first 24 hours after surgery, the time until the first request for pain medication, pain scores at several time points after surgery (0, 1, 2, 4, 8, 12, and 24 hours), and any side effects (such as nausea, vomiting, or sedation) or complications related to the block. The aim is to compare the effectiveness and safety of these two techniques in reducing pain and opioid use after lumbar spine surgery.

Biologic Injection For Adults With Lumbar Disc Herniation

The goal of this clinical trial is to find out whether adding a bone-marrow aspirate concentrate (BMAC) injection during surgery can improve recovery in adults undergoing lumbar microdiscectomy for a lumbar disc herniation. The main questions it aims to answer are: * Does the BMAC injection lead to better disc tissue health after surgery (as seen on MRI scans)? * Does the BMAC injection lead to greater improvement in pain and disability compared to surgery alone? Participants will be adults aged 18 and older who are scheduled for lumbar microdiscectomy surgery. Researchers will compare one group of participants receiving the standard-of-care surgery plus the BMAC injection with another group receiving the same surgery without the injection to see if the injection offers added benefit. Participants will: * Have surgery (microdiscectomy) with or without the injection. * Complete pain and disability questionnaires at several times over 2 years. * Undergo MRI scans at baseline and follow-up to assess disc structure and tissue health. * Provide samples of leftover disc or bone-marrow tissue (as applicable) from surgery for analysis.

Acute Effects of Neurodynamics on Strength and Endurance in Athletes

This study explores the acute effects of neurodynamics, an intervention commonly used by physical therapist to improve nerve mobility and decrease pain, on the strength and muscular endurance in the athletic population. This study aims to find if these interventions can maintain or promote strength and endurance in the hamstrings. The studies results will help physical therapist better prescribe exercise and hands-on treatment for hamstring and sciatic nerve related conditions and injuries.

High-Intensity Laser Therapy Versus Transforaminal Epidural Steroid Injection in Chronic Lumbar Disc Herniation-Related Low Back and Radicular Pain

This prospective, randomized, single-blinded, controlled clinical trial aims to compare the effectiveness of high-intensity laser therapy and fluoroscopy-guided transforaminal epidural steroid injection in patients with chronic low back pain and lumbar radiculopathy. Eligible patients will be randomized into two parallel groups. One group will receive high-intensity laser therapy, and the other group will receive transforaminal epidural steroid injection. All participants will also receive a standardized home-based exercise program. Outcomes will be assessed at baseline, 2 weeks, 6 weeks, and 12 weeks after treatment. The primary outcome will be pain intensity measured by the Visual Analog Scale. Secondary outcomes will include functional disability, neuropathic pain symptoms, quality of life, and functional walking capacity.

Mindfulness-based Psychoeducation in Patients With Lumbar Disc Herniation

This study aimed to investigate the effect of mindfulness-based psychoeducation on mindfulness, automatic thoughts, and pain beliefs in patients with lumbar disc herniation.

Effect of Electromagnetic Field in Lumbar Disc Prolapse Patients

to investigate the effect of electromagnetic field therapy on sciatica and postural control in lumbar disc prolapse patients BACKGROUND: lumbar disc prolapse is a clinical condition resulting from compression of lumbar nerve roots resulting in decreased postural control and alleviating sciatic pain Pulsed electromagnetic field (PEMF) therapy is an easy, non-invasive, safe, and relatively new treatment method that is used with growing interest in physical and rehabilitation medicine. Historically, the benefits from magnetotherapy have been reported for patients with musculoskeletal and neurological disorders

Magnesium Sulfate for Prevention of Emergence Agitation in Lumbar Disc Surgery

In this retrospective study, the effect of intraoperative magnesium sulfate infusion on the incidence of postoperative emergence agitation was evaluated in adult patients who underwent elective lumbar microdiscectomy under general anesthesia. The medical records of patients aged 18-70 years with an ASA physical status of I-II were retrospectively reviewed. Patients were evaluated according to whether they received intraoperative magnesium sulfate infusion as part of anesthetic management. The primary outcome measure was the incidence of emergence agitation in the post-anesthesia care unit; this assessment was based on Ramsay Sedation Scale scores recorded in the post-anesthesia care unit at admission and at 5, 10, 15, and 30 minutes. Secondary outcome measures included postoperative pain scores assessed using the Numeric Rating Scale, intraoperative remifentanil consumption, recovery and extubation times, tramadol requirement in the post-anesthesia care unit, and possible adverse events related to magnesium infusion.

Total Lumbar Disc Prosthesis and Subsequent Work Activity at at Least Five Years After Total Lumbar Disc Replacement

Lumbosciatica is a very prevalent pathology. When conservative treatments fail, surgery should be considered. The traditional surgical treatment is lumbar arthrodesis. The vast majority of patients who undergo spinal fusion cannot return to their same job and a good number of them never work again. Another form of treatment for lumbosciatica is the implantation of a lumbar disc prosthesis. This technique preserves the mobility of the lumbar area that has been operated on. This allows for a greater return to work and a higher percentage of those who return to the same job. This study aims to quantify how many of the patients who have had a lumbar disc prosthesis implanted in the last twenty years have returned to their same job, how many have had to change their jobs, and how many have not returned to work and are now totally or completely disabled from work.

Comparison Of Early Mobilization And Electrical Stimulation On Functional Recovery After Lumbar Disc Herniation Surgery

This randomized controlled trial aims to compare the effectiveness of early mobilization alone versus early mobilization combined with electrical stimulation on functional recovery following lumbar disc herniation surgery. Lumbar disc herniation is a common cause of low back pain and functional limitation, significantly affecting quality of life. Although surgical intervention is effective in patients who do not respond to conservative treatment, optimal postoperative recovery largely depends on appropriate rehabilitation strategies. Early mobilization is widely recommended to prevent complications, preserve muscle function, and facilitate return to daily activities. In addition, electrical stimulation modalities such as neuromuscular electrical stimulation (NMES) and transcutaneous electrical nerve stimulation (TENS) have been increasingly integrated into rehabilitation programs to enhance pain control, muscle activation, and neuromuscular re-education. In this study, a total of 60 participants who have undergone primary lumbar disc herniation surgery will be randomly assigned into two groups. The first group will receive an early mobilization program alone, while the second group will receive early mobilization combined with electrical stimulation (NMES/TENS). The intervention period will last 6 to 8 weeks, with sessions conducted three times per week. Primary outcomes include functional disability measured by the Oswestry Disability Index (ODI) and pain intensity measured by the Visual Analog Scale (VAS). Secondary outcomes include functional mobility assessed by the Timed Up and Go (TUG) test, walking speed assessed by the 10-Meter Walk Test (10MWT), and muscle strength evaluated using manual muscle testing (MMT). The findings of this study are expected to contribute to the development of evidence-based postoperative rehabilitation protocols and to clarify the clinical effectiveness of electrical stimulation in patients undergoing lumbar disc herniation surgery

Evaluation of the Effectiveness of Physical Therapy for Low Back Pain According to Magnetic Resonance Imaging Findings

Low back pain is a common musculoskeletal disorder associated with substantial disability and reduced quality of life. Although magnetic resonance imaging (MRI) is frequently used to identify structural spinal abnormalities, the relationship between MRI findings and treatment outcomes remains unclear. This retrospective study aims to evaluate whether the effectiveness of a standardized physical therapy program differs according to baseline lumbar MRI findings. Medical records of 120 patients with low back pain who underwent lumbar MRI and completed 15 sessions of physical therapy between January 2022 and February 2026 will be reviewed. Patients will be classified into three MRI-based groups: disc herniation, disc degeneration, and non-specific MRI findings. Treatment outcomes will be assessed using changes in Visual Analog Scale (VAS) pain scores and Oswestry Disability Index (ODI) scores before and after treatment. The findings may contribute to identifying patient subgroups that respond differently to conservative treatment and support more individualized rehabilitation strategies.

Dynamic Compliance-Guided Ventilation in Lumbar Surgery

Postoperative pulmonary complications are a frequent cause of morbidity following lumbar stabilization surgery. Conventional ventilation strategies may not adequately reflect intraoperative changes in respiratory mechanics, potentially leading to impaired postoperative pulmonary function. Dynamic compliance-guided ventilation provides a real-time, individualized approach by adjusting ventilatory parameters according to lung compliance. This prospective randomized controlled study aims to evaluate the effects of dynamic compliance-guided ventilation compared with standard ventilation strategies on postoperative pulmonary function in patients undergoing lumbar stabilization surgery. Eligible patients will be randomly assigned to either the compliance-guided group or the conventional ventilation group. In this study, the investigators aim to prospectively compare ventilation with the dynamic compliance (Cdyn) approach-one of the lung-protective ventilation strategies-with conventional ventilation methods in patients undergoing surgery in the prone position. The primary outcome will be evaluated using a modified lung ultrasound scoring system based on the most severely affected regions of aeration loss. Secondary objectives include the assessment of intraoperative hemodynamics, respiratory mechanics, and the effects on postoperative pulmonary function.

Subjective Intraoperative Use of Epidural Steroid Administration Following Discectomy

The purpose of this study is to determine a grading system for inflammation in lumbar disc herniation and which groups, if any, benefit most from the administration of an intra-operative epidural steroid.

Electroacupuncture for Insomnia in Patients With Chronic Sciatica Due to Lumbar Disc Herniation: a Randomized Controlled Trial

The goal of this clinical trial is to learn if electroacupuncture can improve sleep in people with chronic sciatica caused by lumbar disc herniation. It will also assess the safety of this treatment. The main questions it aims to answer are whether electroacupuncture improves sleep quality and whether it reduces pain and improves daily function. Researchers will compare electroacupuncture to a sham treatment, which looks like real acupuncture but has little or no therapeutic effect, to determine its effectiveness. Participants will be randomly assigned to receive electroacupuncture or sham treatment, will receive treatment three times per week for four weeks, and will complete questionnaires about their sleep, pain, and daily activities.

GA + ESP vs. SA + ESP in Lumbar Decompression Surgeries

The purpose of this study is to determine the optimal anesthetic routine for lumbar decompression surgery. General Anesthesia is the standard of care in spine surgery. Spinal anesthesia in decompressive procedures can be the new standard of care. Recently, it has been found that regional analgesia is option that has been shown to improve pain and opioid-related outcomes after spine surgery, but has not yet been studied in combination with spinal anesthesia. This is study that consists of two groups: standard of care general anesthesia with a nerve block and a spinal anesthesia with nerve block. Patients are randomized to either of the two groups. There will be 71 patients enrolled in each group for this study.

Treatment Response to TFESI and DRG Pulsed RF in Lumbar Spinal Stenosis and Disc Herniation

Lumbar radiculopathy caused by conditions such as lumbar disc herniation (LDH) and lumbar spinal stenosis (LSS) can lead to chronic pain and reduced quality of life. In patients who do not respond to conservative treatments, minimally invasive procedures such as transforaminal epidural steroid injection (TFESI) and pulsed radiofrequency (pRF) applied to the dorsal root ganglion (DRG) are commonly used. This study aims to compare treatment responses between patients with lumbar disc herniation and those with lumbar spinal stenosis who have undergone TFESI combined with dorsal root ganglion pulsed radiofrequency. Pain levels and clinical outcomes will be evaluated to determine whether the underlying condition affects treatment effectiveness. The results of this study may help guide clinicians in selecting the most appropriate treatment approach for patients with lumbar radiculopathy.

Clinical and MRI Findings in Lumbar Disc Disease

Low back pain related to lumbar disc disease is a very common condition. Doctors frequently use Magnetic Resonance Imaging (MRI) to look at the spine and diagnose these problems. However, it is not always clear how well the severity of the damage seen on an MRI matches the actual symptoms a patient is experiencing. Sometimes, patients with severe MRI findings have mild symptoms, and vice versa. The purpose of this observational study is to understand the relationship between a patient's clinical symptoms and their MRI results. Researchers want to see if the severity of the spinal damage shown on an MRI can accurately predict how much pain or disability a patient has. Participants in this study are adults (ages 18-70) who are already experiencing symptoms of lumbar disc disease and have recently had an MRI. During the study, participants will: * Complete a questionnaire about the intensity of their back and leg pain. * Fill out a survey about how their back pain affects their daily activities. * Undergo a standard physical and neurological examination by a doctor to check their reflexes, muscle strength, and sensation. Researchers will then compare these physical examination and questionnaire results with the detailed findings from the patient's MRI scans. The goal of this research is to improve diagnostic accuracy and help doctors make better, more personalized treatment decisions for future patients with lower back pain.

IASTM and Vibration Effects on Pain, Functionality, and Kinesiophobia in Lumbar Disc Herniation

The aim of this study is to investigate the effects of Instrument-Assisted Soft Tissue Mobilization and vibration massage therapy on pain, functionality, and kinesiophobia in individuals with lumbar disc herniation.

Comparison of Virtual Reality-Based and Routine Preoperative Education on Surgical Anxiety and Salivary Cortisol

This randomized controlled pilot study aims to compare the effects of virtual reality-based preoperative education and routine preoperative education on surgical anxiety in patients undergoing lumbar disc surgery. In addition to evaluating psychological outcomes, the study will also compare psychometric anxiety assessments with a biological stress marker, salivary cortisol, to examine the relationship between subjective and physiological stress responses. Preoperative anxiety is common among surgical patients and may negatively influence both emotional well-being and physiological stress regulation. Virtual reality-based education may provide a more immersive and engaging learning experience compared to routine education, potentially reducing anxiety levels. Participants will be randomly assigned to either a virtual reality-based education group or a routine preoperative education group. Surgical anxiety will be assessed using validated psychometric measurement tools, and physiological stress response will be evaluated through salivary cortisol analysis. The study will further explore the concordance between psychometric findings and biological stress indicators. The results may contribute to the development of innovative, evidence-based nursing interventions and provide insight into the relationship between psychological and biological indicators of preoperative anxiety.

Regional Anesthesia in Minimally Invasive Lumbar Spine Surgery

Opioid overuse is a widespread public health crisis in the United States with increasing rates of addiction and overdose deaths from prescription opioids. Reducing the need for opiate analgesics in the post-operative setting has become a high priority in minimizing long-term opioid use in surgical patients. This study will serve to demonstrate the efficacy of the addition of regional analgesic techniques in reducing post-operative opioid requirements in patients undergoing common lumbar spinal surgical procedures.

Investigation of Preoperative Factors Influencing the Outcome of Motor Deficits in Patients Undergoing Lumbar Microdiskectomy

Lumbar disc herniations may result in lower limb weakness. In such cases, there is a strong indication for surgical intervention through microdiscectomy. This clinical study aims to investigate preoperative factors that may influence the postoperative outcomes of patients undergoing this procedure.

Evaluation of the Postoperative Efficacy of Bilateral Lumbar Erector Spinae Plane Block (ESPB) in Patients Undergoing Lumbar Disc Herniation Repair Surgery

This prospective observational study aims to evaluate the efficacy of bilateral lumbar erector spinae plane (ESP) block in providing effective postoperative analgesia and its potential impact on early mobilization and length of hospital stay in patients undergoing surgical repair of lumbar disc herniation. Regional anesthesia techniques, particularly erector spinae plane blocks, have become an integral component of multimodal analgesia strategies in postoperative pain management. The ESP block has demonstrated effective analgesia across a wide spectrum of thoracic and abdominal surgeries and is increasingly utilized due to its ease of application and safety profile. By implementing multimodal analgesic techniques, this study seeks to achieve effective pain control, reduce opioid consumption and associated complications, facilitate early mobilization, decrease hospital length of stay, and enhance patient comfort.
