View clinical trials related to Central Sensitisation.
Filter by: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.
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 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?
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.
The goal of this clinical trial is to learn whether pretreatment central sensitization presence affect shoulder steroid injection resuls in patients with rotator cuff pathology. The main questions it aims to answer are: 1. Is central sensitization associated with decreased treatment response? 2. Do the clinical features of patients with central sensitization differ from those of those without? Participants will be applied a shoulder injection and the treatment response will be monitored.
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.
Patients with chronic pain syndrome (CPS) may develop central sensitization wich may lead to increased pain intensity and lower pain threshold sometimes to the extend of hyperalgesia and allodynia. Furthermore, patients with daily use of opioids may develop opioid tolerance, and to a lesser extent opioid induced hyperalgesia. These factors may lead to a higher pain intensity in the perioperative setting resulting in the observed increased opioid dosage needed to treat the acute pain. Furthermore opioid titration may be difficult with higher levels of pain and a higher risk of opioid related adverse effects incl. respiratory depression and sedation. The factors above advocate for utilizing opioid sparing analgesic techniques. In our department as in many others we use an multimodal opioid sparing approach for surgical procedures including epidural anesthesia (EA) as a standard part of the perioperative analgesia strategy after upper laparotomy, as a sufficient epidural anesthesia has shown to provide a stable and often better pain relief than systemic opioids in these patients. Clinically, there is a suspicion that patients with CPS on fixed opioid treatment have a higher frequency of need for epidural optimization, despite the lack of an anatomical reason for this. One potential explanation could be an altered nociception, requesting another EA strategy than in non-opioid patients. Purpose and hypothesis This study will explore the frequency of failed EA, defined as EA with insufficient analgesic effect to the extent were replacements of the epidural is needed within the first 5 postoperative days (PODs), testing the hypothesis that failed epidural occurs more frequent in patients with CPS on fixed opioid treatment than in non-opioid patients without CPS.
Assessing associations between Sensory profiles and nociplastic pain symptoms, and assessing the prognostic value of sensory profiles in the development of nociplastic pain symptoms in a low back pain population.
Temporomandibular disorders are common in the general population, the myogenic subtype being the most frequent. Central sensitization seems to be present in this pathology, with a decreased pain pressure threshold observed in both local and remote areas. The best evidence-based treatment consists in combining education, manual therapy and therapeutic exercise in both temporomandibular and cervical regions. Aerobic exercise showed to be effective in subjects with chronic pain and central sensitization, by inducing an hypoalgesic effect. However, there isn't investigation about the effects of aerobic exercise in subjects with myogenic temporomandibular disorders and central sensitization. Thus, the aim of the pilot study is to determine if adding aerobic exercise to an effective physical therapy programme is more effective than physical therapy alone to improve pain pressure threshold in subjects with myogenic temporomandibular disorders and suspicion of central sensitization.
This experimental study will investigate whether the decreased NFR threshold and increased NFR temporal summation, which are frequently observed in chronic pain patients, are only symptomatic manifestations that occur in the involved limb and indicate peripheral sensitization or generalized manifestations that are also present in the non-involved limbs and thus indicate central sensitization. To gain an idea of the presence of central sensitization, this study will also investigate whether there are increased perception and decreased pain thresholds in response to electrical, thermal, and mechanical stimulation, as well as whether there is a decreased conditioned pain modulation. To investigate this, it is essential to examine different pain populations and locations, in particular, acute pain versus chronic pain populations to compare peripheral versus central sensitization, respectively. Recently, our research group has shown that patients with a traumatic origin of chronic neck pain (chronic whiplash-associated disorders) show central sensitization in contrast to patients with a non-traumatic origin (chronic idiopathic neck pain) who demonstrate only indications for peripheral sensitization. Therefore, this study will also distinguish between complaints of traumatic and non-traumatic origin. The measurements will be performed at different locations, namely the lower and upper limbs. To determine whether the differences depend on the measurement location (= location where experimental nociceptive stimulation is administered) and symptom location (= location of clinical nociceptive stimulation), different patient populations will be compared with each other, as well as with a healthy control population. In acute and chronic whiplash patients and patients with acute and chronic idiopathic neck pain complaints, the complaints are primarily localized in the upper limb. It is hypothesized that in chronic neck pain patients (both whiplash and idiopathic neck pain patients) abnormal values are found in both the upper and lower limbs compared to the healthy controls due to central sensitization. In acute neck pain patients (both whiplash and idiopathic neck pain) only abnormal values in the arm are expected and not in the leg as a result of peripheral sensitization. It is hypothesized that patients with neck pain of traumatic origin will show a stronger sensitization than those with neck pain of non-traumatic origin. In acute and chronic low back pain patients, the complaints are primarily localized in the lower body quadrant. As a result of central sensitization in the chronic low back pain patients, abnormal values are expected in both the upper and lower limbs, while only abnormal values in the leg are expected as a result of peripheral sensitization in the acute low back pain patients. Finally, this study will investigate whether chronic low back and neck pain patients show a similar pattern of central sensitization as fibromyalgia patients, a population with generalized complaints that are primarily attributed to central sensitization.
