Filter by:Introduction. Whiplash is common after road traffic accidents and affects millions of people worldwide; 50% develop chronic symptoms and 15% have their ability to work compromised. The aim of this study was to evaluate an osteopathic intervention in whiplash and determine whether pain, mobility and quality of life improve with respect to conventional treatment. Methodology. A randomised, controlled clinical trial between 13/01/2021_10/08/2022 conducted at Hospital San Juan de Dios del Aljarafe. The control group followed the hospital's protocol, and the experimental group also received an osteopathic intervention. Statistical analysis: Statistical Package for the Social Sciences (SPSS-vs27.0); intra-subject comparison: Student's t-test for dependent samples, Wilcoxon's test; inter-group comparisons: Student's t-test for independent samples, Mann-Whitney U, chi-squared.
Background: Chronic neuropathic pain associated with peripheral neuropathies cannot be attributed solely to lesions of peripheral sensory axons and likely involves alteration in the processing of nociceptive information in the central nervous system in most patients. Few data are available regarding EEG correlates of chronic neuropathic pain. The fact is that effective cortical neuromodulation strategies to treat neuropathic pain target the precentral cortical region, i.e. a cortical area corresponding to the motor cortex. It is not known how these strategies might modulate brain rhythms in the central cortical region, but it can be speculated that sensorimotor rhythms (SMRs) are modified. Another potent way of modulating cortical rhythms is to use EEG-based neurofeedback (NFB). Rare studies previously aimed at relieving neuropathic pain using EEG-NFB training. Methods/Design: The objective of this single-centre, single-blinded, randomized controlled pilot study is to assess the value of an EEG-NFB procedure to relieve chronic neuropathic pain in patients with painful peripheral neuropathy. A series of 32 patients will be randomly assigned to one of the two following EEG-NFB protocols, aimed at increasing either the low-β(SMR)/high-β ratio (n=16) or the α(μ)/θ ratio (n=16) at central (rolandic) cortical level. Various clinical outcome measures will be collected before and one week after 12 EEG-NFB sessions performed over 4 weeks. Resting-state EEG will also be recorded immediately before and after each NFB session. The primary endpoint will be the change in the impact of pain on patient's daily functioning, as assessed on the Interference Scale of the short form of the Brief Pain Inventory. Discussion: The value of EEG-NFB procedures to relieve neuropathic pain has been rarely studied. This pilot study will attempt to show the value of endogenous modulation of brain rhythms in the central (rolandic) region in the frequency band corresponding to the frequency of stimulation currently used by therapeutic motor cortex stimulation. In the case of significant clinical benefit produced by the low-β(SMR)/high-β ratio increasing strategy, this work could pave the way for using EEG-NFB training within the armamentarium of neuropathic pain therapy.
The aim of this retrospective study is to determine the factors affecting the development of chronic pain in patients with thoracotomy in the Thoracic Surgery Operating Rooms of İbn-i Sina Hospital. By identifying these factors, it is aimed to apply the necessary treatments to prevent the development of chronic pain and to improve patient outcomes.
The aim of this study to evaluate the effects of fibromyalgia syndrome accompanying women with chronic migraine on pain, quality of life, sleep, anxiety and depression, central sensitization and functionality.
The study aims to test a mobile intervention on values and goals in chronic pain patients. The cognitive behavioral intervention is a 10-day course in which participants complete a brief intervention each day (about 10-20 minutes a day). The content of the intervention includes the definition of values; development of individualized values and personal value-oriented goals; and implementation of personal goals in every day life. To assess the effectiveness of the intervention, we use a multiple baseline single case design. Baseline measurements will be assessed daily between 10 and 17 days (the exact number will be randomized). Daily measurements will continue during the intervention. After the intervention, another post measurement will be collected.
The objective of this study is to evaluate the feasibility and efficacy of an Augmented Reality (AR) biofeedback intervention to alleviate pain symptoms in individuals suffering from chronic pain of the hand and/or the forearm.
The purpose of the study is to test whether the use of weighted blankets can change the experience of chronic pain and to examine if social, psychological, or health factors influence the perception of the blanket. Multiple blanket weights will be tested.
Six years after, the authors will conduct the same analysis to check if there have been any improvements in the management of analgesic therapy after the measures taken according to the results of the previous study conducted in the same departments. During a single day work three committees, administering a questionnaire to patients or parents, will evaluate the adherence to international recommendations (JCI and WHO) in the management of analgesic therapy.
Veterans who have responded well to Battlefield Acupuncture (BFA), a form of auricular acupuncture, in routine clinical practice will be invited to receive education to insert the needles themselves at home. A 3D-printed wearable prosthetic will also be explored as a means to facilitate needle placement. Primary end-points will include whether adverse events occur over a six-month period and whether the aforementioned prosthesis significantly facilitates needle placement in terms of subjective ease of administration.
Pain is a nociceptive somatosensory process that can arise as a debilitating and chronic symptom in various diseases or following an injury. How pain is experienced can vary widely within and across individuals, and can be shaped by cognitive processes such as learning. Nocebo effects, negative changes in symptom severity attributed to learned outcome-expectations, demonstrate how learning processes can be detrimental for the experience of pain. Research to date has produced inconclusive findings regarding the electrophysiological correlates on nocebo effects. The few studies that have applied electroencephalography (EEG) in this field have pointed towards a potential involvement of alpha-band activity, but the direction of this involvement remains unclear. For example, an EEG study of conditioned nocebo hyperalgesia found a pre to post increase in resting state alpha band power that was correlated with pain catastrophizing scores and not with the magnitude of the nocebo effect. Later, other studies also found pre to post changes in alpha band power, however, these changes were correlated with the magnitude of nocebo effects and not pain catastrophizing. Given the discrepancy in findings, in this study the investigators plan to primarily investigate whether EEG components predict the magnitude of nocebo responses to thermal-pain stimuli. The investigators will also explore electrophysiological correlates during pain anticipation and whether nocebo responses would be significantly related to spectral and temporal EEG biomarkers. This study will utilize a validated model of instructional and associative learning methods (i.e., negative suggestions and classical conditioning, respectively) to experimentally induce nocebo effects on heat-evoked pain. Developing objective, brain-derived markers for nocebo responses, or the detection of individuals most susceptible to nocebo hyperalgesia, will aid in the comprehensive management of pain. This study is conducted at Leiden University.
