Filter by:The MOCAS Study aims to describe the mechanisms through which sleep deficiency affects youth responses to an online pain self-management intervention over a 6-month period. The study is a single arm trial with repeated measurements using surveys, daily diaries, and actigraphic monitoring.
Central Sensitization is an aspect of chronic pain and is associated with over-excitability of the central nervous system. Central Sensitization normally presents itself with other chronic syndromes such as Myofascial Pain Syndrome, so it is difficult to separate the characteristics of the two. The purpose of this study is to determine whether sensitizing healthy muscle using capsaicin, a chilli pepper extract, induces a regional change in ultrasound texture features of the targeted muscle, or the muscles in that are in close proximity. This regional change will be accompanied by electromyography (EMG) recordings to confirm the presence of abnormality. Topical capsaicin and injectable capsaicin will be applied at three different concentrations, 0ug(placebo effect),50ug and 100ug. Research Questions: Does sensitization cause a significant regional change in the texture features of the targeted muscle or surrounding muscles? Is this regional change confirmed by abnormality of motor unit firing rates or EMG amplitudes? Is the response dose dependent? Does the induced central sensitization cause a change in force steadiness? Experimental Protocol: The physician on site will apply surface and intramuscular EMG sensors to the trapezius. A goniometer will be placed on the subjects arm to detect position. Following this, an ultrasound image of the trapezius, supraspinatus and infraspinatus will be taken.The participant will perform an increasing and decreasing contraction.The subject will then have capsaicin injected into their trapezius or applied onto their skin. The exercise and measurements will then be repeated. The ultrasound will be acquired by the Sonosite ultrasound system. The EMG data will be acquired by the Delsys Trigno EMG system for the surface EMG and the Cadwell Sierra Wave system for the intramuscular EMG. The data will be processed through Delsys EMGworks software and MATLAB. Texture features of the pre and post injection ultrasound images will be compared. Decomposition of motor units will allow for the analysis of motor unit action potential firing rate and amplitudes. Analysis of force steadiness will also be calculated via the goniometer. Overall, the findings from this study should present preliminary evidence to inform central sensitization's effects on regional muscle structure changes, functional changes and motor unit activity.
PURPOSE: The main objectives of the study are: 1. To find the efficacy of using cognitive behavioural therapy on chronic low back pain with central sensitization. 2. To assist in planning an ideal physical therapy rehabilitation program for these patients. BACKGROUND: Recent research has shown that CLBP is a multifactorial disorder comprising psychosocial factors like pain catastrophization, fear avoidance and central sensitization. Central sensitization has been defined as "An amplification of neural signaling within the central nervous system that elicits pain hypersensitivity", and "increased responsiveness of nociceptive neurons in the central nervous system to their normal or subthreshold afferent input". Maladaptive behavior, false beliefs and misinformation regarding the cause of the pain are all contributing factors to the chronicity of LBP. Central sensitization has been attributed to cortical reorganization and amplification of the somatosensory representation of the back causing increased pain and further contributing to the maladaptive behavior and beliefs. Cognitive behavioral treatment has been an important intervention for psychological disorders for decades and recently has gained a lot of interest as an intervention for chronic pain in general and CLBP in specific. HYPOTHESES: It will be hypothesized that: Cognitive behavioural therapy will have a significant effect on centrally sensitized pain intensity and disability. RESEARCH QUESTION:" Does cognitive behavioral therapy have a significant effect on chronic low back pain with central sensitization"
There are few studies in the literature regarding increased frequency of neuropathic pain and sleep disturbance and decreased quality of life in Behçet's disease. Frequency of central sensitization was not investigated in patients with Behçet's disease before. In this study, it is aimed to investigate the frequency of central sensitization, neuropathic pain, sleep disorder and quality of life and their relation to each other in Behcet's disease.
The purpose of this study is to investigate the presence of central sensitization in vitamin D deficiency and its effect on cutaneous silent period, pain, and quality of life. The secondary purpose of the study is to investigate whether a change in cutaneous silent period parameters, pain severity and neuropathic sensitization and quality of life after vitamin D replacement.
Background: Endometriosis affects 10% of reproductive aged females, and can have a negative impact on sexual quality of life. Endometriosis can cause pelvic pain with deep penetration during intercourse, as well as other sexual and non-sexual pains. This study will allow us to determine if an increase in sexual pain is related to central sensitization. Purpose: The purpose of this study is to determine if there is an association between the severity of sexual pain and central sensitization in women with endometriosis. Measurement tools: Data will be collected from the Clinic's Data Registry, an online questionnaire, a quantitative sensory test (QST) to measure pain-pressure threshold (PPT) as a marker of central sensitization, and daily entry to an online survey. Primary Hypothesis: Central sensitization (measured by lower pain-pressure threshold) will be associated with an increased severity of deep dyspareunia, as well as a tenderness of the bladder/pelvic floor and depression, in women with endometriosis.
