NCT ID: NCT06269068 Recruiting - Clinical trials for Central Sensitisation

Investigation of the Relationship Between Central Sensitization and Neuropathic Pain in Lumbar Disc Herniation

Start date: January 16, 2024
Phase:
Study type: Observational

Central sensitization (CS) is as increased response to normal or sub-threshold stimuli of central nervous system and its close relationship with in many musculoskeletal diseases with chronic pain has been demonstrated in several studies. CS is also one of the main mechanisms proposed in the generation of neuropathic pain, and the relationship between pain sensitization and neuropathic complaints has been shown in different diseases.In this study, it was aimed to investigate the effect of central sensitization on the distribution pattern and neuropathic character of pain in patients with lumbar disc herniation who applied to the physical medicine and rehabilitation outpatient clinic.

NCT ID: NCT06169917 Recruiting - Pain Clinical Trials

Pain Processing In Relation To Breathing

Start date: May 14, 2023
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to investigate the effect of breathing on the processing of experimental pain in healthy participants. The main questions are: 1. Does breathing rate influence the spatial extent of thermally induced secondary hyperalgesia, a proxy of central sensitization? 2. Does resonance frequency breathing influence the autonomic nervous system, compared to baseline and compared to paced breathing at a natural frequency? 3. Is spinal excitability, measured using the magnitude of the nociception withdrawal reflex (NWR), affected by resonance frequency breathing, compared to paced breathing at a natural frequency? Participants: - will receive heat stimuli - 's skin's sensitivity will be tested using quantitative sensory testing tools. - will receive various instructions on the speed of their breathing - 's heart rate, respiratory rate and sweat response will be measured - will fill in questionnaires Researchers will compare the spatial extent of sensitivity resulting from application of heat stimuli during paced resonance frequency breathing compared to paced breathing at a natural frequency to see if the breathing rhythm influences central sensitization processes.

The Segmental Distribution of Hypersensitivity in Patients With Chronic Subacromial Pain Syndrome

Start date: September 20, 2022
Phase:
Study type: Observational [Patient Registry]

This study aimed to determine the distribution of pain sensitivity according to body segments in patients with central sensitization associated with chronic subacromial pain syndrome (SPS).This cross-sectional study included patients with chronic SPS and central sensitization (patient group) and the same number of healthy participants as controls. The presence of central sensitization was determined using the Central Sensitization Inventory. To determine the segmental distribution of pain sensitivity, pressure pain threshold measurements were performed bilaterally from the shoulder, forearm, and leg.

NCT ID: NCT06127693 Completed - Chronic Pain Clinical Trials

Childhood Adversity, Inflammatory Reactivity and Persistent Pain

CAIR
Start date: June 21, 2022
Phase:
Study type: Observational

The goal of this observational study is to investigate how adverse experiences during childhood are linked to people experiencing persistent pain and fatigue in adulthood. The questions the investigators aim to answer are: 1. Does participant-reported childhood adversity predict levels of IL-6 and TNF-α after in vitro provocation of whole blood using endotoxin? 2. Do levels of IL-6 and TNF-α after in vitro immune provocation using endotoxin predict vulnerability to persistent pain and fatigue after in vivo immune provocation (tetravalent influenza vaccine)? 3. Do levels of IL-6 and TNF-α after in vitro immune provocation using endotoxin predict vulnerability to persistent pain and fatigue after in vivo neural provocation? For this study, the investigators will recruit and enrol 96 healthy human adults (18 - 65 years old) with a range of adverse experiences during childhood. Participants will attend 2 study sessions during which the investigators will take a sample of blood, assess pressure pain threshold before and after cold water immersion, assess heart rate variability, and assess the surface area of secondary skin hypersensitivity after electrical stimulation. At the end of the first session, participants will receive the influenza vaccination.

NCT ID: NCT06043141 Recruiting - Clinical trials for Carpal Tunnel Syndrome

Investigation of the Relationship Between Pain Sensitization and Diagnostic Parameters in Carpal Tunnel Syndrome

Start date: October 1, 2023
Phase:
Study type: Observational

The aim of this observational, cross-sectional study is to investigate the relationship between pain sensitization and ultrasonographic and nerve conduction studies in patients diagnosed with carpal tunnel syndrome (CTS). The main questions it aims to answer are: - Can threshold values be determined ultrasonographically and electrodiagnostically in patients who develop pain sensitization? - Are pressure pain threshold values and central sensitization inventory scores correlated with ultrasonographic and nerve conduction studies of the median nerve?

NCT ID: NCT05986513 Not yet recruiting - Chronic Pain Clinical Trials

Brain MRI for Knee OA

Start date: September 1, 2023
Phase: N/A
Study type: Interventional

It has been estimated that 300 million people worldwide have osteoarthritis (OA), and this has increased by 97% over the past 25 years. OA is degenerative joint disease that has joint cartilage break down and causes the surrounding bone to change and rub. The pain and loss of mobility experienced by people with knee OA can seriously reduce quality of life, while pain management causes significant healthcare spending. Unfortunately, the pain associated with OA is complex and difficult to treat other than to have a total knee replacement surgery to replace the damaged bone and surrounding tissues with artificial ones. Our research study plans to use advanced magnetic resonance imaging techniques and novel analysis methods to determine if specific parts of the brain are responsible for difficult to describe and diagnose aspects of chronic pain. This study will help us better understand the effects of chronic pain in the brain and the results will help guide future research into new therapeutic options that would focus on relieving the brain dysfunction caused by chronic pain.

NCT ID: NCT05941780 Recruiting - Fibromyalgia Clinical Trials

Pain Phenotypes in Patients With Fibromyalgia Syndrome

Start date: July 10, 2023
Phase:
Study type: Observational [Patient Registry]

Fibromyalgia Syndrome (FMS); is a complex syndrome characterized by many symptoms such as chronic widespread pain, fatigue and sleep disorders, cognitive dysfunctions and psychiatric disorders. It has been stated that there is an urgent need for studies examining the clinicimetric and psychometric properties of the pain phenotype criteria in terms of patients receiving the most appropriate treatment, clinicians deciding on the appropriate treatment, and contributing to the research of scientists. Despite all this, no study has yet been found that describes the pain phenotypes in fibromyalgia syndrome and how different types of pain affect patients. The primary aim of this study is to determine the chronic pain phenotypes in individuals with FMS. The secondary aim of this study to determine the inter-rater and intra-rater reliability of the algorithm used in the determination of pain phenotypes and to assessment the clinical effects of different pain phenotypes on individuals with FMS in terms of pain severity, disease severity, quality of life and catastrophe.

NCT ID: NCT05701696 Recruiting - Fibromyalgia Clinical Trials

The Relationship Between Neuropathic Complaints and Central Sensitization in Fibromyalgia

Start date: January 16, 2023
Phase:
Study type: Observational

Fibromyalgia (FM) is the prototype of a group of diseases known as central sensitivity syndromes, whose relationship with pain sensitization is well defined. Central sensitization (CS) is also one of the mechanisms involved in the pathophysiology of neuropathic pain. Neuropathic pain, which is a common complaint in FM patients, is likely to be one of the clinical manifestations of central sensitization. Therefore, in this study, it was aimed to investigate the relationship between CS and neuropathic pain.
