RESUMEN
OBJECTIVE: to verify the acute effect of running a half marathon on pelvic floor muscle (PFM) function and electromyographic (EMG) activity in female runners with and without urinary incontinence. METHODS: This is a cross-sectional pilot study. The sample was divided into two groups: runners with urinary incontinence (with UI) and runners without urinary incontinence (without UI). A semi-structured form and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI-SF) were used for data collection. The EMG and PFM function were evaluated using the PERFECT method before and immediately after running a half marathon. RESULTS: A total of 14 runners were included (8 with UI; 6 without UI). Runners with and without UI did not show significant differences for EMG and PERFECT. The acute effects of the half marathon on runners without UI were reduced PFM function in terms of strength (p = 0.00), reduced endurance (p = 0.02), and reduced repetition (p = 0.03), and an increase in EMG measured by the median frequency (p = 0.02). Runners with UI showed reduced PFM function in terms of strength (p = 0.05) and repetition (p = 0.01). CONCLUSION: there was no difference in the acute effects of the half marathon on PFM function and EMG in women with and without UI.

OBJECTIVE: To determine the prevalence and factors associated with urinary incontinence (UI) in female crossfitters. METHODS: This is a cross-sectional study. Data were collected using assessment forms: Knowledge, Attitude and Practice survey for young female athletes; Incontinence Severity Index; and International Consultation on Incontinence Questionnaire for UI. Descriptive analysis was conducted to obtain absolute and relative frequencies, means and 95% confidence intervals (95% CI). Multivariate analysis was carried out to determine the association between UI and sociodemographic, gynecological-obstetric, and anthropometric variables, associated morbidities, previous history and physical activity. RESULTS: Prevalence of UI, in the 189 included volunteers, was 38.6% and the most frequent type was stress UI (69.9%). A total of 72.6% of incontinent women reported urine loss during CrossFit training. Knowledge (53.4%) and attitude (86.2%) regarding UI were generally adequate, while prevention, management and treatment were inadequate (96.3%). The predominant characteristics of UI were frequency of once a week or less (74.0%), in small amounts (86.3%), mild intensity (57.5%) and slight impact on quality of life (64.3%). In multivariate analysis, no variable was significantly associated with UI. CONCLUSIONS: The prevalence of UI in female crossfitters was 38.6%. The factors investigated did not contribute to the development of UI.

Osteoporosis and the risk of falls increase the risk of fractures and events of falls. Prescriptions and programs for different forms of exercise have different impacts on the risk of falls, and exercises from multiple categories of whole-body vibration can be effective. This study aims to evaluate the effectiveness of whole-body vibration (WBV) protocol combined with multicomponent training (MCT) in elderly women with osteoporosis and their history of falls. Our proposal is a protocol for a randomized clinical trial, divided into two stages: First, development of a protocol for WVB combined with MCT for elderly women with osteoporosis and a history of falls, under the Guidelines of the American College of Sports Medicine, and following the recommendations of the Standard Protocol Items Recommendations for Interventional Trials (SPIRIT), and second, a randomized controlled clinical trial following the Consolidated Standards of Reporting Trials (CONSORT). This trial will have implications for the effectiveness of a vibration protocol combined with multicomponent exercise on the risk of falls and quality of life for older women with osteoporosis. We expect that adding full-body vibration to an exercise protocol will decrease the risk of falls and improve participants' quality of life, as well as their strength, balance, and functional capacity.
RESUMEN
OBJECTIVE: The primary aims of this study are to compare neck disability in masticatory myofascial pain subjects versus asymptomatic controls, and to evaluate the correlation between neck disability and muscle pain. DESIGN: Two groups composed this case-control study: a symptomatic group comprised of 27 subjects diagnosed with masticatory myofascial pain, as determined by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), and a control group comprised of 28 asymptomatic subjects. The collected variables were pain intensity (visual analogue scale), pressure pain threshold of the temporomandibular joint, anterior temporalis, masseter, sternocleidomastoid muscle, upper trapezius and Achilles tendon (digital dynamometer, kgf/cm(2)), and neck disability (Neck Disability Index). Statistical analysis included Student's t-test and the Pearson product-moment correlation coefficient (5% significance level and 95% confidence interval). RESULTS: The symptomatic group showed greater neck disability with a mean (SD) of 11.8 (7), as compared with 2.8 (2.4) for the asymptomatic group (p<0.05). A negative correlation was found between neck disability and pressure pain threshold of the anterior temporalis (r=-0.4, 95% CI -0.6 to -0.15, p=0.002), the sternocleidomastoid (r=-0.35, 95% CI -0.56 to -0.09, p=0.007) and the upper trapezius (r=-0.37, 95% CI -0.58 to -0.12, p=0.005). CONCLUSION: Our results reinforced the clinical interconnection between masticatory and cervical structures, insofar as subjects with masticatory myofascial pain reported greater neck disability, which, in turn, was correlated with regional muscle sensitivity.

AIM: To compare the craniocervical angles and distances between temporomandibular dysfunction (TMD) and free TMD subjects. CASUISTIC AND METHODS: The sample consisted of young adults, of both genders, with age ranging between 18 and 30 years. TMD diagnosis was based on the clinical criteria of the Research Diagnostic Criteria for TMD (RDC/TMD), associated with self-reported symptoms of TMD. For radiological analysis we measured three angles and two distances of craniocervical region. RESULTS: Of the 56 subjects, only 23 completed all stages of research, which were divided into two groups: (1) free TMD group - composed of 11 individuals; (2) TMD group - constituted of 12 subjects. The most common clinical diagnosis of TMD was arthralgia (75.0%) followed by myofascial pain without limited mouth opening (58.4%). Among the self-reported symptoms of TMD, the most frequents were facial (83.4%) and neck (66.6%) pain. Of radiological measurement, only plane atlas angle (APA) (p=0.026) and anterior translation distance (Tz C(2)-C(7)) (p=0.045) showed statistical difference between groups TMD (APA=16.7+/-1.63; Tz C(2)-C(7)=28.7+/-2.58) and free TMD (APA=21.64+/-1.24; Tz C(2)-C(7)=19.82+/-3.29). CONCLUSION: It could be verified that the symptomatic TMD patients presented a flexion of the first cervical vertebra associated with an anteriorization of the cervical spine (hyperlordosis).
