Participants will answer three questionnaires: FSFI (the Female Sexual Function Index), MENQOL (Menopause-specific Quality of Life) and MEEM (Mini-Mental State Examination). The results will be compared according to treatment group.
INTRODUCTION: The autonomic nervous system (ANS) is responsible for controlling several visceral functions, including the motility and secretion of the gastrointestinal system (GIS). Alterations in the functioning of the ANS can directly influence the physiological mechanisms of the GIS. Due to the importance of the ANS in the control of various body functions, strategies aimed at acting in this system have become extremely important and have been widely used in the literature. Some of the studies involving ANS analysis have shown that osteopathic manipulative treatment is able to promote a reduction in sympathetic ANS activity and an increase in parasympathetic ANS activity in asymptomatic youngsters, however, none of them addressed the GIS, already known to be influenced by autonomic fibers. OBJECTIVE: To evaluate the immediate effects of GIS-directed osteopathic techniques on ANS behavior and pain sensitivity to pressure in young people without symptoms of gastrointestinal disorders. METHODS: The present study is characterized by a randomized, single-blind clinical trial, in which 42 asymptomatic individuals will be recruited, regardless of gender, aged between 18 and 30 years. Volunteers will be randomly distributed into two groups called intervention protocol and placebo protocol. The intervention protocol will be performed by a professional with 10 years of clinical experience in the field of Osteopathy and will perform the techniques of Generalized Discharge of the peritoneum and intestinal wings, Mobilization of the Cecum, technique for the Mesentery Root, Release of the D1-D2 angle, technique for the Sigmoid Colon. The approximate duration of the set of techniques will be 15 minutes with the volunteers positioned supine on a stretcher. The placebo protocol will apply in the same way regarding the positioning and duration of the techniques. The therapist will position the hands in the same regions of the intervention protocol, maintaining superficial contact for 3 minutes in each region, without therapeutic intent. Volunteers will be evaluated for outcomes before and immediately after performing the protocols. The heart rate variability will be measured by capturing the intervals between each beat in ms, using a heart rate monitor and extracting the linear indices in the domain of time, frequency and geometric heart rate variability. The pressure pain threshold will also be measured using a pressure algometer that will be positioned in the vertebral region of T5-L3. Comparisons of variables (indices of HRV and pressure pain threshold) between the intervention protocol group and placebo protocol will be performed using the Student's T test (normal data) or the Mann-Whitney test (non-normal data). All results will be discussed at the 5% significance level.
Introduction: Parkinson's disease (PD) is responsible for several changes in the body, such as balance, gastrointestinal and autonomic disorders and are associated with impairments in the clinical prognosis of these individuals. In this sense, therapies capable of minimizing this impact are extremely important. Osteopathy has become an alternative treatment for individuals with neurological disorders and has been shown to be effective in treating various conditions, including PD. Objective: a) to evaluate the acute effect of visceral manipulation directed to the intestines and visceral plexuses in the autonomic nervous system of PD patients; b) identify the effect of this approach, after four visits, on balance, plantar pressure, gastrointestinal disorders and autonomic nervous system in this population. Materials and Methods: For this randomized clinical trial, 28 adults diagnosed with PD will be recruited. Subjects will be randomized to protocols in two groups: intervention protocol and placebo protocol, where both will consist of 4 visits twice a week. The intervention protocol will consist of osteopathic manipulative techniques and the sham protocol will consist of simulation of therapy, where the therapist will place his hands in the same regions of the intervention protocol, with superficial contact and without therapeutic intention in each region. The outcome measures of the study will consist of Berg balance assessment and plantar pressure, Rome survey on gastrointestinal disorders, and assessment of autonomic modulation by means of heart rate variability analysis. Volunteers and evaluators will be blind to the protocol and not informed of their order. Only the person responsible for the intervention will not be blind to the protocol. Data will be analyzed according to normality (Shapiro-Wilk test), and comparisons of outcomes between the moments (pre and post) will be performed using the T-student test for paired data or Wilcoxon, as normal and for comparisons between protocols. placebo and intervention, Student's T-test for unpaired data or Mann-Whitney test according to normality will be applied. The adopted statistical significance will be fixed at 5%.
The purpose of this clinical trial is to learn whether the study medicine prevent symptoms of COVID-19 in adults who have been exposed to household member(s) with a confirmed symptomatic COVID-19 infection. All participants in the study will receive treatment for COVID-19 as needed, based on their regular doctor's recommendation. Two-thirds of participants will also receive two study medicines (PF-07321332 and ritonavir) by mouth twice a day for either five or ten days. We will compare the experiences of people receiving the study medicines to those of the people who do not. This will help us determine if the study medicines are safe and effective
From the change in self-regulation, memory is inhibited, allowing individuals to suppress or ignore unwanted or outdated associations and thus help to filter information relevant to dietary goals from irrelevant information. Provoking changes in neuroplasticity and cortical excitability contribute to the regulation of neural activity. Both could be modified by applying direct electrical current to the sensorimotor cortex, with polarity/current-dependent results, and their effect would last for hours after the end of stimulation. Transcranial Direct Current Stimulation (tDCS), translated into Portuguese as Estimulação Transcraniana por Corrente Contínua (ETCC) is a neuromodulating tool in which a low-intensity electrical current is applied to the scalp to modulate neuronal activity.
INTRODUCTION: Chronic low back pain (CLBD) is one of the major public health problems in the world. Given the complexity of the situation, complementary and alternative practices such as pain neuroscience education (PNE), clinical hypnosis (HC) and osteopathic manipulative treatment (OMT) are options for we manage these patients. OBJECTIVE: The aim of this study will be to evaluate the effects of OMT associated with PNE through HC on pain and disability in patients with CLBP compared to PNE and HC. MATERIALS AND METHODS: The study design will be a randomized clinical trial and 40 adults diagnosed with chronic low back pain will be recruited. Subjects will be randomized in two groups: the first group (G1) will be submitted to the PNE based on information from the book "Explain Pain" with hypnotic suggestions. Group 2 (G2) will receive PNE following the book "Explain Pain" with hypnotic suggestions associated with OMT. Volunteers will be evaluated by a blind researcher the interventions performed in the allocation of groups. The evaluation moments will be pre-intervention and immediately after the end of the last intervention for G1 and G2. Volunteers continued to be evaluated 4 weeks after completion of the protocols. Pain will be evaluated as the main outcome, being evaluated by the numerical pain scale. Pain will also be assessed by the pressure threshold using a pressure algometer device (Fnd-50, PIAB 50-n, Italy) in the lumbar region. Still as the main outcome, disability will be assessed using the Oswestry Disability Questionnaire. As secondary outcomes, the patient's global impression of improvement, central sensitization, biopsychosocial factors will be evaluated. The patient's global impression of improvement will be assessed using the Percentage of Improvement Scale with a score of -5 to +5; the Central Sensitization will be assessed using the Central Sensitization Questionnaire and the biopsychosocial factors using the Start Beck Toll questionnaire. In addition, the behavior of the autonomic nervous system will be evaluated through the Heart Rate Variability (HRV), which will be analyzed through linear methods, in the domains of time and frequency, and by geometric indices. The researcher/evaluator will be blinded to the allocation of intervention groups. Given the nature of the study, it is impossible to blind the researcher/therapist and volunteers.
Osteoarthrosis (OA), a multifactorial degenerative process, is responsible for joint pain and functional limitation. In the hand, more specifically in the proximal and distal interphalangeal joints of the fingers, it is one of the sites of greatest manifestation of the disease. Numerous treatments, whether drug, rehabilitation or surgery, have been proposed with the aim of both interrupting the natural evolution of the disease and alleviating or stopping the symptoms. This study aims to evaluate the effectiveness of personalized Photobiomodulation Therapy (PBT) with regard to alleviating symptoms and improving the quality of life of these patients with the disease.
