1. Pelvic floor muscles after prostate radiation therapy: morpho-functional assessment by magnetic resonance imaging, surface electromyography and digital anal palpation
ABSTRACT Aim: To evaluate the radiotherapy (RT) effect in the pelvic floor muscles (PFM) function in men with prostate cancer (PC). Materials and Methods: A cross-sectional study included three groups of patients with PC and RT indication: 1) Pre-RT group: evaluated before the beginning of RT; 2) Acute group: evaluated between six months and one year after

3. Physical and functional aspects of persons with multiple sclerosis practicing Tai-Geiko: randomized trial
OBJECTIVES: This study aimed to verify the influence of Tai-Geiko on the physical and functional aspects of people with multiple sclerosis (MS). METHODS: This was a parallel-group, randomized trial with two arms. People with MS were allocated to an experimental group (EG) (n=10) and control group (CG) (n=09). The participants received multidisciplinary car

4. Parto diferido emg ravidez gemelar bicoriônica: Um caso com 154 dias de latência
Resumo O parto pré-termo espontâneo complica frequentemente as gestações multifetais, condicionando elevada morbimortalidade perinatal. Em determinados casos, o nascimento prematuro do primeiro feto pode não requerer o nascimento do(s) feto(s) restante(s), que podem permanecer in utero, com o objetivo de diminuir a morbidade e mortalidade neonatal. Atua

5. The use of surface electromyography to assess transfemoral amputees: methodological and functional perspective
Abstract Aim: Surface electromyography (sEMG) has been established as a safe non-invasive method to investigate neuromuscular function. However, the use of this instrument to assess lower limbs of transfemoral amputees still presents a lack of standardization in its methods of signal acquisition and processing. The aim of this study was to review the curre

6. Multivariate linear regression analysis to evaluate multiple-set performance in active and inactive individuals
Abstract Aim: To determine how EMG, anthropometric, and psychological factors, and physical activity levels affect isokinetic peak torque performance (IPT) of multiple set exercise sessions. Methods: 20 participants (27±7 years old), classified as active (A=10) and inactive (I=10), performed 10x10:40secs of maximal unilateral knee flexions and extension

7. Control of a robotic knee exoskeleton for assistance and rehabilitation based on motion intention from sEMG
Introduction: This work presents the development of a novel robotic knee exoskeleton controlled by motion intention based on sEMG, which uses admittance control to assist people with reduced mobility and improve their locomotion. Clinical research remark that these devices working in constant interaction with the neuromuscular and skeletal human system impr

8. Adaptation of a smart walker for stroke individuals: a study on sEMG and accelerometer signals
Abstract Introduction: Stroke is a leading cause of neuromuscular system damages, and researchers have been studying and developing robotic devices to assist affected people. Depending on the damage extension, the gait of these people can be impaired, making devices, such as smart walkers, useful for rehabilitation. The goal of this work is to analyze chang

9. EFEITOS DA ALTURA DO SELIM NO DESEMPENHO E NA ATIVAÇÃO MUSCULAR DURANTE TESTE DE WINGATE
RESUMO O presente estudo teve como objetivo analisar o desempenho anaeróbio e a ativação muscular durante um teste de ciclismo supramáximo em três diferentes alturas do selim. Doze ciclistas competitivos completaram um teste incremental em cicloergômetro e três testes de Wingate de 30 s em diferentes alturas do selim (referência, baixa e alta), de fo

10. Proposal of surface electromyography signal acquisition protocols for masseter and temporalis muscles
Abstract Introduction The aim of this study was to propose a method of electrodes positioning on the superficial masseter and anterior temporalis muscles for surface electromyographic (sEMG) recordings in order to overcome some known methodological constraints. Methods Fifteen volunteers with normal occlusion participated in two experimental sessions withi

11. Dexterous hand gestures recognition based on low-density sEMG signals for upper-limb forearm amputees
Abstract Introduction Intuitive prosthesis control is one of the most important challenges in order to reduce the user effort in learning how to use an artificial hand. This work presents the development of a novel method for pattern recognition of sEMG signals able to discriminate, in a very accurate way, dexterous hand and fingers movements using a reduce

12. Efeitos de dexmedetomidina perineural no nervo ciático em ratos
Resumo O presente estudo foi desenvolvido para testar a hipótese de que dexmedetomidina em dose alta aumentaria a duração da antinocicepção a um estímulo térmico em modelo de rato de bloqueio do nervo ciático sem causar danos ao nervo. Os ratos foram anestesiados com isoflurano. Após os registros da eletromiografia (EMG), os nervos ciáticos direito
