Acute Effect of a Half-Marathon over the Muscular Function and Electromyographic Activity of the Pelvic Floor in Female Runners with or without Urinary Incontinence: A Pilot Study.

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.

Ampleness of head movements of children and adolescents with sensorineural hearing loss.

INTRODUCTION: Head movements are controlled by the vestibular system. Children with sensorineural hearing loss can present restrictions in ampleness of head movements due to damage in the vestibule-cochlear systems, resulting from injury in the inner ear. OBJECTIVE: To evaluate the ampleness of head movements of children with normal hearing and children with sensorineural hearing loss and compare data between groups. METHODS: Cross-sectional study that evaluated the ampleness of head movements of 96 students, being 48 with normal hearing and 48 with sensorineural hearing loss, of both sexes, with aged between 7 and 18 years old. The performance of ampleness of head movements was analyzed by a manual goniometric evaluation, according the references proposed by Marques. To the statistical analysis we used the t-Student test in case of normality of the data or the Mann-Whitney test when did not applied the suppositions of normality. RESULTS: Hearing loss children showed less mean in ampleness of all movements of head compared to normal hearing children, pointing difference to movements of flexion (p = 0,001), lateral inclination to the right (p = 0,025) and lateral rotation to the left (p = 0,021). CONCLUSION: Hearing loss children showed reduction in the ampleness of these head movements: flexion, lateral inclination to the right and lateral rotation to the left compared to normal hearing children.
