The Impact of Metabolic Status on Pain and Central Sensitization in Women With Lipedema: A Cross-Sectional Observational Study

The aim of this study is to evaluate the effect of metabolic markers (HOMA-IR, triglyceride/HDL ratio, HbA1c, waist and hip circumference measurements, BMI, etc.) on pain and central sensitization in patients diagnosed with lipedema. The primary objective is to investigate the association between metabolic markers and central sensitization. The secondary objective is to assess the relationship between metabolic markers and pain intensity, pain phenotype, and functional status.

Neuropathic Characteristics of Subacromial Pain Syndrome

This single-center observational study aims to investigate neuropathic pain descriptors and their relationship with central sensitization in patients diagnosed with subacromial pain syndrome (SAPS) who have had shoulder pain for at least 3 months. A total of 82 participants aged 19 years or older will be recruited from the Physical Medicine and Rehabilitation outpatient clinic of Izmir City Hospital. After obtaining informed consent, participants will complete validated questionnaires assessing pain severity (VAS), neuropathic pain characteristics (painDETECT), central sensitization (Central Sensitization Inventory), and shoulder function (SPADI). Range of motion will be measured using a goniometer. No imaging or invasive procedures will be performed. Using the central sensitization scale and pain detect, the presence or absence of the 7 pain descriptors will be investigated in patients with subacromial pain syndrome with or without central sensitization and neuropathic pain pattern and it will be investigated whether the contribution of hyperalgesia, one of these pain descriptors, to neuropathic pain and central sensitization in patients with subacromial pain syndrome is greater than the contribution of other pain descriptors.The results of this study are expected to provide insight into pain mechanisms and guide clinical management in patients with SAPS.

Impact of GON PRF on Central Sensitization in Migraine Patients

Background: Central sensitization and cutaneous allodynia are key mechanisms implicated in migraine chronification and disability. Pulsed radiofrequency (PRF) of the greater occipital nerve (GON) has emerged as a neuromodulatory intervention for refractory headache disorders; however, its effects on central sensitization remain insufficiently characterized. Objective: To prospectively evaluate changes in central sensitization, allodynia, and migraine-related disability following GON pulsed radiofrequency in patients with migraine. Methods: In this prospective observational study, adult patients with episodic or chronic migraine undergoing ultrasound-guided GON pulsed radiofrequency were evaluated at baseline and at 1 and 3 months post-procedure. Central sensitization was assessed using the Central Sensitization Inventory (CSI), cutaneous allodynia using the Allodynia Symptom Checklist (ASC-12), and migraine-related disability using the Migraine Disability Assessment Scale (MIDAS). Monthly headache days and acute medication use were also recorded. Results: Changes in CSI, ASC-12, MIDAS scores, headache frequency, and acute medication use over follow-up were analyzed using repeated-measures statistical methods. Conclusions: This study provides prospective data on sensory and clinical outcomes following GON pulsed radiofrequency, contributing to the understanding of its potential role in modulating central sensitization in migraine.

Central Sensitization Syndromes and Post-Traumatic Stress in Women: Psychological Profile and Intervention

Central Sensitivity Syndromes (CSSs) are a group of conditions that are highly prevalent, particularly among women, and often occur alongside post-traumatic stress disorder (PTSD). This research project has two aims: Study 1) to investigate the psychological profiles of women with CSS-PTSD comorbidity; and Study 2) to design and evaluate the effectiveness of distinct interventions for each profile identified in Study 1.

Can Virtual Reality Exercise Help Restore Both Body and Mind in Chronic Low Back Pain

The goal of this clinical trial is to learn if an immersive virtual reality (VR) exercise program can help reduce back pain and improve physical function and psychological well-being in adults with chronic low back pain. The main questions it aim to answer are * Does the virtual reality (VR) exercise reduce back pain? * Does it lead to positive changes in how participants perceive pain? * Does it improve back flexibility and reduce disability in daily activities? * Does it help reduce the fear of movement and negative thoughts related to pain? Method Wear a Meta Quest 3s device and participate in a 15-minute virtual reality exercise program called 'FitXR'. Be evaluated for their back pain, sensory test, range of motion, and level of disability in daily life before and after the exercise program. Complete questionnaires about their thoughts and feelings regarding their pain and movement.

Comparison of Treatment Alternatives for Myofascial Pain Causing Central Sensitization

Myofascial pain is a regional muscle pain condition characterized by hard local areas and tender bands, known for the presence of trigger points in muscle tissue. The treatment is to eliminate the etiologic factor. Regular exercise is recommended to relieve the trigger points. Occlusal splints, considered the gold standard in the treatment of temporomandibular joint disorders, are used to manage and control symptoms. In this study, patients between the ages of 18-45 years who applied to Çukurova University Faculty of Dentistry, Department of Prosthodontics with the complaint of myofascial pain and scored above 40 on the central sensitization scale will be taken as a sample.

VR-Enhanced Psychoeducation for Chronic Pain: A Primary Care Pilot Study

This pilot study aims to evaluate the integration of virtual reality (VR) with a psychoeducational program for individuals experiencing chronic pain and central sensitization. Chronic pain significantly hampers daily life, and the condition of central sensitization intensifies this challenge by making the pain more acute. Our research is grounded in the hypothesis that VR, when used to complement conventional psychoeducational methods, can enhance engagement and understanding of pain management strategies, thus potentially improving patient outcomes. Key objectives and related measured variables include: Usability and Feasibility: Evaluated through the System Usability Scale (SUS) responses from both participants and healthcare professionals, assessing the ease of use and integration of VR into the psychoeducational program. Participant Engagement and Program Adherence: Determined by participants\' satisfaction with the VR system, using Likert scale questionnaires, and tracked through session attendance and program completion rates. Impact on Chronic Pain Management and Emotional Well-being: Assessed through changes in the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), and the Hospital Anxiety and Depression Scale (HADS) collected at baseline, post-intervention, and 4-8 weeks follow-up Self-management of Chronic Pain: Monitored through the Central Sensitization Inventory (CSI) and changes in patient functionality and mobility using the EuroQol-5D-5L scale, measured at baseline, post-intervention, and 4-8 weeks follow-up. Healthcare Professionals\' Perceptions: Investigated using SUS scores and qualitative feedback on the applicability and benefits of VR in clinical practice for chronic pain management. Participants will complete eight 90-minute sessions, engaging with VR to supplement the program\'s content. This approach aims to provide immersive experiences that deepen the understanding and management of chronic pain. Participant feedback on the VR experience, alongside observed changes in pain management and overall well-being, will be critically examined. By targeting individuals suffering from chronic pain, this research aims to offer healthcare professionals an innovative tool for enhancing pain management strategies. Integrating VR into psychoeducational content, the study seeks to promote more engaging and effective learning experiences, potentially leading to improved outcomes in chronic pain management.

Pain Perception and the Autonomic Nervous System

In this study, we want to investigate how pain processing and sensation are related to a certain part of the nervous system, the so-called autonomic nervous system. For this purpose, we apply heat and pressure stimuli to the skin and test pain processing by means of ratings scales and sensory tests. Breathing, heart rate and sweat response are also measured. To assess the spinal cord level, we measure muscle response (measured by electromyography, EMG) to electrical stimulation. Additionally, sensory nerves will be stimulated at the ear and participants will also be given various questionnaires to complete.

The Role of Central Sensitization in Pain, Functionality, and Quality of Life in Cancer Patients

Pain is one of the most important and challenging symptoms in cancer patients. Depending on the stage of cancer, approximately 40% to 70% of patients complain of pain. With the increasing lifespan of cancer patients due to developing treatments, pain palliation has become even more crucial to improve their quality of life. Cancer-related pain can develop through multiple mechanisms such as the tumor itself, metastasis, or the methods used in treatment. The type of pain can be nociceptive, neuropathic, or mixed. Central sensitization refers to the increased response of central nervous system nociceptive neurons to normal or subthreshold stimuli. Recently, central sensitization (CS) has been recognized as a potential pathophysiological mechanism underlying a group of chronic pain diseases such as fibromyalgia, temporomandibular joint disorder, irritable bowel syndrome, interstitial cystitis, tension-type headache, and chronic low back pain. Since pain perception varies from person to person, physicians should assess the character of pain thoroughly and not rely solely on peripheral pain treatment in cases with a component of central sensitization. The lack of evaluation of the extent to which central sensitization affects patients and the failure to fully determine the factors influencing it appear to be clinical limitations for now. There are studies suggesting that central sensitization may be a significant factor in chronic refractory pain in cancer patients, indicating the need for consideration of alternative options to classical treatments. To the best of our knowledge, no study has been conducted in Turkey to investigate the frequency of central sensitization and its impact on treatment outcomes in chronic cancer pain patients visiting outpatient clinics. The aim of this study is to investigate the frequency of central sensitization and its effect on pain and quality of life in chronic cancer pain patients attending algology clinics in multiple centers in Turkey.
