Techniques for Registration of Myoelectric Activity of Women's Pelvic Floor Muscles: A Scoping Review.

INTRODUCTION AND HYPOTHESIS: Surface electromyography is commonly applied to measure the electrophysiological activity of the neuromuscular system. However, there is no consensus regarding the best protocol to assess pelvic floor muscles. METHODS: A scoping literature review was carried out in six databases, using MeSH descriptors. It included studies with electromyographic assessment in adult women presenting or not with pelvic floor dysfunction. The results were presented in categories to contribute to the development of a protocol considering the most used parameters for non-invasive assessment of myoelectric activity of pelvic floor muscles. RESULTS: A total of 1,074 articles were identified, and 146 studies were selected for analysis. The intravaginal probe was used in 80.8% of the studies, the bipolar sensor with metallic plates placed on both sides of the vagina was the most frequent (71.3%), with a reference electrode positioned on the anterior superior iliac spine (33.5%). The supine position with hip and knee flexed (45.2%) was the most frequent position used. Of the studies, 44.5% normalized the data by maximum voluntary contraction (MVC) whereas 44.5% performed an average of 3 MVCs. CONCLUSIONS: The most frequently used protocol for the pelvic floor is the bipolar intracavitary probe with metal plates positioned at 3-9 o'clock and introduced distally to the vaginal introitus with the volunteer in the supine position and the hip and knee flexed with the reference placed on the anterior-superior iliac spine.

Oral health quality of life is associated to jaw function and depression in patients with myogenous temporomandibular dysfunction.

OBJECTIVE: To determine which factors influence and better differentiate between good and poor oral health-related quality of life (OHRQoL) in patients with myogenous TMD and which cut-off could predict a good/poor OHRQoL. METHODS: Fifty-eight women with myogenous TMD were included. Factors of interest were collected (i.e., demographic variables, depression symptoms (Symptom Checklist-90 R (RDC/TMD)), pain intensity (Visual Analog Scale), jaw function (Mandibular Functional Limitation Questionnaire), and OHRQoL (Oral Health Impact Profile-14). A multivariable regression model, logistic regression, and receiver operating curve (ROC) analyses were conducted. RESULTS: Depression symptoms (ß = 0.139) and jaw function (ß = 0.478) were significantly associated with OHRQoL in the multivariable model. The best model to discriminate between good/poor OHRQoL included only jaw function (AUC = 0.90), with the best cut-off of 17 points (sensitivity: 0.93; specificity: 0.79). CONCLUSION: Depression symptoms and jaw function were significantly associated with OHRQoL. The best model and cut-off to discriminate good/poor OHRQoL included only jaw function.

What are the best parameters of low-level laser therapy to reduce pain intensity and improve mandibular function in orofacial pain? A systematic review and meta-analysis.

PURPOSE: To determine the effectiveness of laser therapy for managing patients with orofacial pain (OFP). In addition, to determine which parameters provide the best treatment effects to reduce pain, improve function, and quality of life in adults with OFP. METHODS: Systematic review. Searches were conducted in six databases; no date or language restrictions were applied. Studies involving adults with OFP treated with laser therapy were included. The risk of bias (RoB) was performed with the Revised Cochrane RoB-2. A meta-analysis was structured around the OFP type, and outcomes. Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) assessed the overall certainty of the evidence. RESULTS: Eighty-nine studies were included. Most studies (n = 72, 80.9%) were considered to have a high RoB. The results showed that laser therapy was better than placebo in improving pain, maximal mouth open (MMO), protrusion, and tenderness at the final assessment, but with a low or moderate level of evidence. The best lasers and parameters to reduce pain are diode or gallium-aluminum-arsenide (GaAlAs) lasers, a wavelength of 400-800 or 800-1500 nm, and dosage of <25 J/cm2. CONCLUSIONS: Laser therapy was better than placebo to improve pain, MMO, protrusion, and tenderness. Also, it was better than occlusal splint to improve pain, but not better than TENS and medication.Implications for rehabilitationLaser therapy was found to be good in improving pain, maximal mouth opening, jaw protrusion, and tenderness at the end of the treatment.For patients with all types of temporomandibular disorders (TMDs) (myogenous, arthrogenous, and mixed), the following lasers and parameters are recommended: diode or gallium-aluminum-arsenide (GaAlAs) laser, wavelength of 400-800 or 800-1500 nm, and a dosage <25 J/cm2.For patients with arthrogenous TMDs, the following lasers and parameters are recommended: Diode laser and a wavelength between 400 and 800 nm.For patients with myogenous TMDs, the following lasers and parameters are recommended: diode laser, wavelength between 800 and 1500 nm, and dosage of <25 J/cm2.For patients with mixed TMDs, the following lasers and parameters are recommended: diode, GaAlAs, or infrared laser, a wavelength of 800-1500 nm, a dosage >100 J/cm2, and an application time between 15 and 30 s or >60 seconds.

The accuracy of computerized biophotogrammetry in diagnosing changes in the cervical spine and its reliability for the cervical lordosis angle.

BACKGROUND: Accuracy studies of biophotogrammetry protocols require standardization similar to radiography. OBJECTIVE: To estimate the diagnostic accuracy of a biophotogrammetric assessment protocol for cervical hyperlordosis, compared to radiography, and its intra- and inter-examiner reliability for measuring the cervical lordosis angle. METHODS: A study of diagnostic accuracy in women complaining of cervical pain. Two photos were taken using the CorelDraw biophotogrammetric protocol and one radiograph using the Cobb C1-C7 method. The Intra- and Inter-examiner reliability was calculated using the Kappa index and the intraclass correlation coefficient (ICC). The Bland-Altman plot and the ROC curve were presented. RESULTS: The sample consisted of 19 women. The accuracy of biophotogrammetry was 94.73% and the reliability between biophotogrammetry and radiography presented an ICC of 0.84 and a Kappa of 0.87. The excellent intra (ICC = 0.94) and inter-examiner (ICC = 0.86) reliability of the biophotogrammetry was confirmed. The area under the ROC curve was 93.5%. The Bland-Altman plot indicated differences between the two instruments close to the mean (1.5∘). CONCLUSION: The biophotogrammetric protocol proved to be accurate in diagnosing cervical hyperlordosis, with excellent reliability between the biophotogrammetric and radiographic assessments. It also demonstrated excellent intra- and inter-examiner reliability in measuring the cervical lordosis angle.

Ventilation asymmetry, diaphragmatic mobility and exercise capacity in men with traumatic brachial plexus injury.

OBJECTIVE: To investigate the repercussions of traumatic brachial plexus injury (TBPI) on diaphragmatic mobility and exercise capacity, compartmental volume changes, as well as volume contribution of each hemithorax and ventilation asymmetry during different respiratory maneuvers, and compare with healthy individuals. The velocity of shortening of the diaphragm, inspiratory, and expiratory muscles were also assessed. PARTICIPANTS: The cross-sectional study was conducted with 40 male individuals (20 with TBPI who have not undergone nerve transfer surgery [mean age 30.1 ± 5.3] and 20 healthy paired by age and body mass index). Only patients with C8-T1 root avulsion were studied. MAIN OUTCOME: Compartmental and hemithoracic volumes, as well as asymmetry between the affected and unaffected sides were assessed using optoelectronic plethysmography. The 6 minute walking test was performed to evaluate exercise capacity, while diaphragm mobility was assessed during quiet breathing (QB) using an ultrasound device. RESULTS: TBPI patients with mean lesion time of 174 ± 45.24 days showed a decreased pulmonary function, respiratory muscle strength, exercise capacity, and diaphragm mobility (all p < .001) compared with healthy. The pulmonary ribcage compartment of the affected side was the main contributor to the reduction in volume during inspiratory capacity, vital capacity, and inspiratory load imposition (all p < .05). This compartment also exhibited a higher ventilation asymmetry with reduced shortening velocity of the inspiratory ribcage muscles. CONCLUSION: Compared with healthy, TBPI patients who have not undergone nerve transfer surgery present low exercise capacity and diaphragmatic mobility, as well as reduced volume of the upper ribcage compartment on the affected side that leads to reduced shortening velocity and ventilation asymmetry.

The presence of migraine symptoms was associated with a higher likelihood to present eating disorders symptoms among teenage students.

OBJECTIVE: To investigate the association between migraine and signs and symptoms of eating disorders among teenagers. And as secondary objectives: to investigate the prevalence of eating disorders signs and symptoms and to identify the prevalence of migraine among teenagers. METHODS: Cross-sectional study was carried out in public schools which included adolescents aged 11-18 years, of both sexes. For eating disorders evaluation two self-reported questionnaires were used: Eating Attitudes Test-26 (EAT-26) and The Bulimic Investigatory Test of Edinburg (BITE). The presence and characterization of headache were verified following the International Classification of Headache Disorders (ICHD-II). RESULTS: 607 adolescents (388 females) with mean age of 13.9 years (95% CI: 13.7; 14) were included. The eating disorders symptoms based on EAT-26 (p = 0.041) and the bulimia nervosa symptoms (p = 0.014) evaluation were more prevalent among teenagers with migraine compared with non-migraine. Also, in multivariate analysis, the adjusted odds ratio (OR) to present bulimia nervosa symptoms is 1.85 times higher among females than males. And, the adjusted OR to present bulimia nervosa symptoms among teenagers with migraine is 1.51 times (OR) higher than among non-migraine. CONCLUSIONS: The presence of migraine symptoms were associated with a higher likelihood to present eating disorders symptoms among teenagers, especially in females, that was associated with a 1.85-fold increase in the risk to present bulimia nervosa symptoms. LEVEL OF EVIDENCE: III, Evidence obtained from cross-sectional study.

Neck and back muscle chains hypomobility in women with migraine.

OBJECTIVE: To compare the mobility of neck and back flexor and extensor muscle chains in women with migraine, chronic migraine and headache-free. METHODS: This is a cross-sectional study. The muscle chain test was performed based on the theoretical assumptions of the Busquet method, in women with migraine (MG, n = 24), chronic migraine (CMG, n = 36) and headache-free (CG, n = 27). The evaluation of neck and back mobility was performed by an examiner expert in the Busquet method with the aid of cervical range of motion (CROM®) device (neck muscles) and the Tiltmeter® application (back muscles). RESULTS: Compared to woman headache-free, women with migraine (MD = -12° [CI95% = -19°, -5°] and chronic migraine (MD = -15° [CI95% = -21°, -8°] present reduced mobility in the neck extensor muscle chain. Also, in the back extensor muscle chain, migraine vs headache-free (MD = -9° [CI95% = -15°, -2°]) and chronic migraine vs headache-free (MD = -10° [CI95% = -16°, -4°]) and in the back flexor muscle chain, migraine vs headache-free (MD = -6° [CI95% = -10°, -0.1°]) and chronic migraine vs headache-free (MD = -7 [CI95% = -11°, -2°]), with an effect sizes varying between 1.19 e 2.38. No difference was found between groups for neck flexor muscle chain. CONCLUSION: Women with migraine and chronic migraine have hypomobility of the neck and back extensor muscle chains, and of the back flexor chain.

Linking assessment instruments for brachial plexus injury to the international classification of functioning, disability and health.

BACKGROUND: Brachial plexus injuries (BPI) affect not only body structure and function, but also several aspects of individual's well-being. Considering the crescent need for assessing such patients through a biopsychosocial perspective, linking meaningful concepts of BPI instruments to the International Classification of Functioning, Disability and Health (ICF) provides a useful overview of how the ICF components are contemplated on the current measurements available. PURPOSE: To identify patient-reported outcome measures (PROMs) specifically designed for BPI assessment and link the content with the ICF. STUDY DESIGN: Content Analysis through ICF linking. METHODS: The study was conducted in two steps: the first one encompassed a literature review to identify questionnaires specifically designed for assessing patients with BPI, where two PROMs were eligible: the Brachial Assessment Tool (BrAT) and the Impact of Brachial Plexus Injury Questionnaire (IBPIQ); in the second phase, the items of such instruments were linked to the ICF by two independent reviewers, in accordance to the methodology proposed by Cieza et al. RESULTS: 54 different significant concepts were identified from the 74 questionnaire items and linked to 49 distinct ICF categories. The categories were mostly related to the activities and participation component (56.9%, n = 29), followed by body functions (27.45%, n = 14), body structures (9.8%, n = 5) and environmental factors component (1.96%, n = 1). CONCLUSION: The questionnaires developed for adults with BPI were BrAT and IBPIQ. Although both instruments presented with a diverse coverage of ICF components, their content had a major focus on activities and participation domain and poorly or did not addressed environmental factors. Thus, other instruments could be considered in a complementary way for clinical assessment.

Techniques for registration of myoelectric activity of women's pelvic floor muscles: a scoping review protocol.

OBJECTIVE: The objective of this review is to identify the most frequently used protocols for analyzing the myoelectric activity of the pelvic floor muscles during surface electromyography in women aged 18 years or older. INTRODUCTION: Surface electromyography is normally used in assessment and treatment for research purposes when it is intended to quantitatively measure the electrophysiological behavior of the neuromuscular system. However, although there are internationally standardized, non-invasive assessment protocols for most muscle groups, there is no consensus for pelvic floor muscles, which makes it difficult to standardize in scientific research and clinical applicability. INCLUSION CRITERIA: Studies that explore registration protocols and filtering parameters of surface electromyographic signals in women aged over 18 years old with or without pelvic floor dysfunction will be considered. Studies encompassing either electromyographic biofeedback as a treatment resource only or electroneuromyography (needle electrode) will be excluded. METHODS: Primary studies published in the previous 10 years in MEDLINE, Embase, Scopus, Web of Science, CINAHL, and Cochrane Central databases will be included. The search will encompass descriptors registered in MeSH. The identified articles will be assessed for eligibility by two independent reviewers in three stages: evaluation by title, abstract, and full text. If there is any disagreement, a third reviewer will be consulted. Data will be extracted and organized in standardized spreadsheets. The results will be assigned to categories in order to facilitate the organization of a protocol with the most commonly used parameters for non-invasive assessment of myoelectric activity of pelvic floor muscles.

Proprioceptive neuromuscular facilitation compared to conventional physiotherapy for adults with traumatic upper brachial plexus injury: A protocol for a randomized clinical trial.

BACKGROUND: Traumatic upper plexus injury affects daily living activities performance and participation of individuals. Physical therapy treatment has a fundamental role on functional recovery, but it is still an unexplored and challenging field. AIM: To develop a protocol to evaluate the efficacy of Proprioceptive Neuromuscular Facilitation (PNF) compared to conventional physiotherapy (CPT group) on functionality and quality of life. METHODS: A committee was formed by four physical therapists to develop the treatment protocol. A Delphi study was carried out in order to quantify the level of agreement. A protocol for a randomized controlled trial was proposed to evaluate the effectiveness of the protocol in improving functionality and quality of life, according Consolidated Standards of Reporting Trials. Participants will be randomly assigned (1:1) to PNF or CPT group and two weekly sessions will be carried out for 12 months postsurgery, with a three-month follow-up. The main outcome measurements are: upper limb functionality, quality of life, range of motion, muscle strength, tactile sensitivity, and pain, which will be assessed at baseline, on the 6th, 9th, and 12th months postsurgery. RESULT: A PNF protocol was developed for traumatic upper brachial plexus injury, consisting of 11 illustrated exercises, three for immediate postoperative and eight for postoperative. Biomechanical objectives, observations, positions of patients and therapists and PNF principles, procedures and techniques have been described. An 80% agreement on all items in the first round of the Delphi study was achieved. CONCLUSION: A protocol based on the PNF-concept was developed with the aim of improving the functionality and quality of life of individuals undergoing nerve transfer after traumatic injury to the upper plexus. The detailed description of a physical therapy treatment protocol through an appropriate method will allow its use in clinical practice and in future studies with this population.

MRI in migraineurs: are there abnormalities in the area where the myofascial trigger points are palpable and in volume measurements?

INTRODUCTION: Patients with migraine may present a higher quantity of myofascial trigger points (MTrP) and alterations in the cervical muscles when compared to non-migraineurs. The magnetic resonance imaging (MRI) is a robust method for the study of human soft tissues and could be useful to investigate these points. OBJECTIVES: To identify the presence of MTrP in the descending fibers of the trapezius muscle in women with migraine and to quantify the muscle volume by MRI, correlating it with the headache characteristics. METHODS: A cross-sectional analytic study was conducted among 14 women, eight in migraine group, and six in without migraine group. The presence of MTrP was evaluated using Simons' criteria, and linolenic acid capsules subsequently marked the areas. MRI was performed with 1.5T, T1-weighted sequence, and T2 in the axial, sagittal, and coronal planes. The T1-weighted sequences were performed with and without gadolinium contrast. RESULTS: The T1-weighted image analysis with and without gadolinium did not show any signal alteration in the MTrP areas in both groups. The migraine group presented more MTrP in the trapezius muscle (MD [95%CI] = 1[1; 3]; MD [95%CI] = 1[0; 2] right and left side, respectively), and a smaller muscle volume (MD [95%CI] = -198.1[-338.7;-25.6], MD [95%CI] = -149.9[-325.05;-0.13] right and left side, respectively) than non-migraineurs. The migraine frequency presented a negative strong correlation with the trapezius volumes (r = -0.812; p = 0.014). CONCLUSION: Migraineurs present more MTrP and a smaller muscle volume than non-migraineurs. The trapezius volume is negatively correlated with migraine frequency. MRI is not a suitable outcome measure for assessing MTrP.

Contract-relax technique compared to static stretching in treating migraine in women: A randomized pilot trial.

INTRODUCTION: Physical therapy is often used by patients with headache, including modalities such as muscle stretching exercises. OBJECTIVES: To evaluate the feasibility of a pilot trial aimed at determining the efficacy of the proprioceptive neuromuscular facilitation (PNF) contract-relax technique compared to static stretching for treating migraineurs. METHODS: This pilot trial allocated 30 migraineur women (23 ±â€¯4 years) into PNF (n = 15) and static stretching groups (n = 15). The interventions were performed twice a week (16 sessions, 8 weeks). The feasibility outcomes included successful random allocation of 30 patients during a 12-month period, the proportion of eligible patients randomly assigned to each group, and the proportion of those who completed the 30-day follow-up. The outcomes of headache characteristics; medication intake; severity of migraine-related disability; neck disability; cervical mobility; pressure pain threshold; adverse effects and global perception of change were evaluated at baseline, after the end of treatment and after 30-day follow-up. RESULTS: The recruitment rate was 4.66% participants/month. The proportion of eligible patients randomly assigned to each group and for those who completed the 30-day follow-up was 88.23% and 100%, respectively. Both groups improved in headache-related outcomes. The perception of change was important for 67% of the PNF group and 47% of the static stretching group. No differences were found between groups regarding the studied outcomes. CONCLUSION: This is a feasible pilot trial. The PNF contract-relax technique was no more effective than static stretching for treating migraine, but both techniques improved the headache, the severity of migraine-related disability and the satisfaction after treatment.

Efficacy of proprioceptive neuromuscular facilitation compared to other stretching modalities in range of motion gain in young healthy adults: A systematic review.

The objective of this study was to evaluate the efficacy of proprioceptive neuromuscular facilitation (PNF) on range of motion (ROM) gain in young healthy adults. We performed a systematic review of randomized controlled trials and quasi-randomized trials, including young healthy adults. The interventions were: PNF compared with different PNF techniques, control, other muscle stretching exercises and musculoskeletal manipulations. The outcome measures were: articular ROM and adverse effects. The final number of included studies was 46, involving 1,864 adults. There was difference on ROM comparing assisted hold-relax (HR) on diagonal plane to control, based on very low-quality evidence. There was also difference on ROM comparing assisted HR to self-HR; self-contract-relax (CR) to control; assisted CR contract to control; and assisted HR contract to control, based on low-quality evidence. Moderate-quality evidence shows that results differ between self HR and control (SMD: 0.95; 95%CI 0.03, 1.86; I249%; P = 0.16) in terms of ROM gain. When performing the other comparisons, the results were based on low or very low-quality evidence and do not allow to state if PNF is more or less effective than other stretches for improving ROM in healthy young adults. No adverse effects were mentioned.

Life quality, depression and anxiety symptoms in chronic post-traumatic headache after mild brain injury.

Post-traumatic headache (PTH) is the most common symptom found in the post-traumatic syndrome, whose onset occurs within seven days of the trauma. The condition is characterized as acute when it persists for up to 3 months. PTH beyond this period is considered chronic. OBJECTIVES: The objective of this study was to determine the clinical features of chronic post-traumatic headache (cPTH) and its association with depression, anxiety and quality of life. METHODS: A total of 73 female subjects were evaluated. Patients were divided into three groups: (a) group without headache, CONTROL, n=25; (b) cPTH group, n=19; and (c) MIGRAINE, n=29, with all subjects in the 11-84 year age group. Symptoms of anxiety and depression were evaluated by the Beck inventories of anxiety and depression, and quality of life assessed by the Lipp and Rocha quality of life inventory. Qualitative variables were analyzed using the Chi-square or Fisher's exact tests and expressed as percentages whereas quantitative variables were analyzed by ANOVA, Mann-Whitney or Kruskal-Wallis tests with data expressed as mean±standard deviation, p<0.05. RESULTS: Subjects with cPTH presented with headache manifesting similar features to those found in migraine. The cPTH group was associated with similar levels of anxiety and depression to the migraine group and higher than the CONTROL (p<0.001). Quality of life of individuals with cPTH was similar to that of subjects with migraine and lower than CONTROL subjects (p<0.05). CONCLUSIONS: cPTH presents similar clinical characteristics to migraine. Subjects with cPTH had high levels of anxiety and depression symptoms and reduced quality of life.

A cefaleia é o sintoma mais encontrado na síndrome pós-traumática, iniciando-se dentro de sete dias após o trauma. Sua a forma aguda dura até três meses e a crônica persiste após este período. OBJETIVOS: O objetivo deste estudo foi determinar as características clínicas da cefaleia pós-traumática crônica (CPTc) e sua associação com a depressão, ansiedade e com nível de qualidade de vida. MÉTODOS: Foram avaliados 73 sujeitos do gênero feminino, divididos em três grupos: (a) grupo sem cefaleia (CONTROLE, n=25), (b) grupo com CPTc (n=19) e (c) migrânea (MIGRÂNEA, n=29), com idades variando entre 11 e 84 anos. Os sintomas de ansiedade e depressão foram avaliados pelos inventários de ansiedade e depressão de Beck e a qualidade de vida pelo inventário de qualidade de vida de Lipp e Rocha. As variáveis qualitativas foram analisadas pelos testes qui-quadrado ou exato de Fisher e expressas em percentuais e as quantitativas por ANOVA, Mann-Whitney ou Kruskal-Wallis com os dados apresentados em média±desvio padrão, p<0,05. RESULTADOS: Os sujeitos com CPTc apresentaram cefaleia com características semelhantes as encontradas na migrânea. A CPTc esteve associada aos níveis de sintomas de ansiedade e depressão similares ao grupo com migrânea e superior ao CONTROLE (p<0,001). Os níveis de qualidade de vida dos sujeitos com CPTc mostraram-se semelhantes aos dos sujeitos com migrânea e inferior ao CONTROLE (p<0,05). CONCLUSÕES: A CPTc apresenta características clínicas semelhantes a migrânea. Os sujeitos com CPTc apresentam elevado nível de sintomas de ansiedade e depressão e nível de qualidade de vida reduzida.
