The control of upper-limb prostheses is commonly realized via the detection, processing and classification of myoelectric signals. Pattern recognition techniques enable users to control prosthetic devices by contracting remaining muscles, so that up to nine hand positions can be distinguished with high accuracy. It is however difficult to identify single fingeror sophisticated finger-movements....

OBJECTIVE Assess the effect of different controlled lumbar back support tightness levels on trunk muscle activity. DESIGN Two-way repeated measure design assessing lumbar back support tension and submaximal trunk extension moments on trunk muscle electromyographic activity. BACKGROUND Biomechanical studies on lumbar back supports often use electromyography (EMG) to assess the affect on trun...

PURPOSE To characterize the electrical activity of the masseter muscle during swallowing of liquids in healthy young adults. METHODS Participants were 14 volunteers considered healthy according to the inclusion and exclusion criteria established for this study. The bilateral electromyographic evaluation of the masseter muscle was conducted at rest and in swallowing tasks of 14.5 ml, 20 ml and...

Introduction: Diaphragm and lateral abdominal muscles frequently show sparing effects to muscle relaxants. This study compared visual estimation of neuromuscular transmission corrugator supercilii adductor pollicis (AP) with electromyographic measurements wall during recovery from vecuronium-induced intense block. Methods: 60 patients undergoing elective surgeries under general anesthesia were ...

BACKGROUND AND OBJECTIVES: Understanding the importance of surface electromyography as a complementary method to understand the myofunctional status of the stomatognathic system, this study aimed at analyzing the frequency of altered and normal electromyographic indices in a sample of subjects with temporomandibular disorders, in addition to their relation with pain complaint. METHODS: Particip...

Swallowing is under the control of premotoneurons located in the medullary solitary tract nucleus. Although rats with transected midbrain do not seek out food, they are able to ingest food present near the mouth, and acute food deprivation induces an increase in food intake. Leptin is a satiety signal that regulates feeding behavior. Because leptin receptors are found within the caudal brainste...

BACKGROUND The aim of the proposed study is to analyze the effect of a six-week osteopathic visceral manipulation (OVM) program on the flexion-relaxation phenomenon in individuals with non-specific chronic low back pain (LBP) and functional constipation. METHODS/DESIGN An assessor-blinded, two-arm, randomized, placebo-controlled trial will be conducted. The sample will comprise 76 individuals...
