Filter by:Background: Chronic widespread pain is challenging in the management of the patient with rheumatoid arthritis (RA), affecting approximately one third of this patient population. However, pain is not always caused by disease activity (inflammation) but can be associated to central pain mechanisms as seen in fibromyalgia (FM). FM is characterized by widespread pain and tenderness; often accompanied by disturbed sleep, fatigue, cognitive impairment, emotional distress and multiple symptoms from various organ systems. Among patients with RA the prevalence of concomitant FM is reported to be 12-17% compared to 1-3% in the general population. In general the pain, felt by the fibromyalgia patients is considered to be due to lower pain thresholds because of abnormal central pain processing. Pain reported by RA patients with concomitant FM could potentially be explained by this phenomenon. Little is known about RA patients fulfilling criteria for FM. Muscles-studies of FM patients have not found any histopathological explanation of the pain felt, however an old study of muscle changes in RA patients found changes that could explain muscle pain. Small fiber neuropathy (SFN) is a condition associated with autoimmune diseases, and evidence suggests that SFN is likely to contribute to the pain observed in FM. Objectives: To determine the diagnostic test accuracy (sensitivity and specificity) of both muscle- and skin-biopsies for fibromyalgia phenotyping and detection by clinical referral (RA with concomitant FM) as the reference standard (i.e. fulfilment of 2016 FM criteria). Data collection: Will be done as study subjects are included and stored in REDCAP. Eligibility criteria for participants and settings where the data will be collected: RA patients will be assessed in the daily clinic in Esbjerg and Odense and examined for concomitant FM (I.e. satisfying the 2016 criteria for FM). Patients will afterwards be invited to participate in the study. Inclusion will continue until 25 RA patients fulfilling FM criteria and thus based on the expected prevalence at least 25 (- and maximum 50) RA patients not fulfilling FM critieria has undergone the index tests. Whether participants form a consecutive, random, or convenience series: Participants form a consecutive series. Description of the index test and reference standard: Twenty-five RA patients with concomitant FM and more than 25 (- maximum 50 patients) RA patients not fulfilling FM criteria will undergo the index tests. Muscle and skin biopsies will be performed in each group using standardized techniques. The reference standard will be fulfillment of the 2016 criteria for fibromyalgia. Estimates of diagnostic accuracy and their precision: Regarding muscle- and skin biopsies sensitivity, specificity and positive predictive value will be calculated using two times two table. Regarding skin biopsies, median values in the two groups (RA +/- FM) will be compared using a two-sample t-test.
The lung is the organ most affected by COVID-19. There are patients who successfully overcome the acute COVID-19 infection and their lungs return to a normal state. However, a significant number present dyspnea and fatigue as sequelae without having a pulmonary origin, but with a significant impact on functionality. In our published studies in relation to fatigue in patients with symptoms attributed to persistent COVID, the investigators have shown that there is muscle involvement, observing a decrease in mechanical efficiency. This muscle involvement causes stimulation of ventilation through the ergoreceptors, causing ineffective ventilation. This affectation can be explained by the findings obtained in the muscle biopsies that the investigators have performed, where the investigators observed a splitting of the basement membrane of the capillaries causing an alteration in the diffusion of metabolic substrates and oxygen. The main objective of our project is to be able to observe the response in ventilatory efficiency in patients with symptoms of post-covid fatigue after ingesting beet juice.
The goal of this clinical trial is to evaluate the digital stabilizing splint in management of masticatory muscle disorder. The main question it aims to answer are: • is the digital stabilizing splint effective in treatment of masticatory muscle disorder signs and symptoms after 3 months follow up ? Participants will be asked to ware the splint and progressively increasing the duration of splint wear, starting from 8 hours per day for 3 months .
The purpose of this research study is to test the feasibility and response of a new exercise protocol on improving physical activity in adolescents with cerebral palsy.
The goal of this clinical trial is to test ketone bodies in healthy elderly and young individuals. The main question it aims to answer are: • Do ketone bodies improve skeletal muscle function? Participants will ingest a ketone monoester and skeletal muscle function will then be evaluated by: - Special magnetic imaging techniques - Intravenous infusion of tracer-marked nutrients - Performance tests on a ergometer bike and in a dynamometer Researchers will compare the outcomes between within the young and elderly groups and between the young and the elderly group to investigate if age has an effect on the outcomes.
Objectives: To observe the effect of newly-created individualized upper airway muscle functional training on the condition and intraday symptoms of OSA patients; to study the effect of this training method on the excitability of the genioglossus muscle cortex; to analyze the factors affecting the efficacy of upper airway training in the treatment of OSA and screening suitable population for upper airway training: Design: A randomized double-blind controlled trial. SAS 9.3 statistical software (SAS Institute, Cary, North Carolina, USA) was used to generate a random number table, and the selected patients were randomly divided into experimental group 1, experimental group 2, and control group according to the ratio of 1:1:1 with 100 cases each. Unit: Shenyang, China Participants: Consecutive specific OSA patients, who are potential candidates for the treatment of upper airway training (n=300), will be recruited from a sleep center or respirologists, psychiatrists, otolaryngologists and dentists practicing with broad inclusion criteria (age: 20-75 years, AHI:15-50/h; BMI<40 kg/m2). Interventions: The three groups of subjects completed 7-day functional training and control training of upper airway muscles in different modes, respectively completed polysomnography, neck circumference, Berlin questionnaire and Epworth sleepiness scale before and after training, The genioglossus myoelectric activity was measured after transcranial magnetic stimulation and the excitability of the genioglossus cortex motor center was used to determine the efficacy of different training. After regression analysis, the factors affecting the efficacy of upper airway muscle group training were analyzed to screen the OSA patient population suitable for upper airway muscle group training.
To compare the effects of stretching exercises versus thermotherapy on RLS symptoms and sleep quality among pregnant women. Research hypotheses: - Pregnant women who perform leg stretching exercises exhibit lower RLS symptoms severity and pain level than those who applied thermotherapy. - Pregnant women who perform leg stretching exercises exhibit higher sleep quality than those who applied thermotherapy.
Hemophilia A and B are inherited disorders characterized by deficient or missing coagulation factors VIII or IX, respectively, of which the main long-term clinical manifestation is joint damage. Patients with haemophilia (PwH) are susceptible to clinical joint bleeding that may cause irreversible joint damage. Some degree of damage may already occur after the first haemarthrosis or even in children who never experienced clinically evident joint bleeds. Joints are mechanical systems with a structure strictly related to functioning. Therefore, any alteration in structure may have an impact on function (starting from the primary level of posture and anti-gravity muscles), which might in turn stress the joints and increase the risk of bleeding.The primary aim of this study is to investigate the changes in posture and the mechanical properties of anti-gravity muscles of adolescent PwH. The secondary aim is to determine the effect of joint dysfunction on posture in adolescent PwH.
Research Problem: To know the immediate effects of high speed and low amplitude cervical manipulation on the electromyographic activity of the masseter muscles of physiotherapy students at the University of the Americas Course objective: To compare the immediate effects of high-speed, low-amplitude cervical manipulation on the electromyographic activity of the masseter muscles versus a placebo intervention in kinesiology students at the University of the Americas. Specific objectives: To describe the changes in the electromyographic activity of the masseter muscles of the high-speed cervical manipulation group in students of the physiotherapy school of the University of the Americas of the Santiago Centro campus. To describe the changes in the electromyographic activity of the masseter muscles of the placebo group in students of the physiotherapy school of the University of the Americas of the Santiago Centro campus. Methodology: Single-blind, randomized clinical trial. Expected results: Significant differences are expected between the intervention group and the control group. This is reflected in a decrease in electromyographic activity in the masseter muscles after high-speed cervical manipulation.
