Vibration of the masseter and temporalis muscles in normal human adult subjects elicits a tonic vibration reflex with unexpected features. The electromyographic response is not asynchronous as in the limb muscles, but involves well-defined spikes with a one-to-one temporal relation to the vibration cycles. The effect of various parameters such as muscle stretch, vibration frequency or amplitude...

In this study, we analyzed the relationship between running economy (RE) and biomechanical parameters in a group running at the same relative intensity and same absolute velocity. Sixteen homogeneous male long-distance runners performed a test to determine RE at 4.4 m.s(-1), corresponding to 11.1% below velocity at the ventilatory threshold. We found significant correlations between RE and biom...

OBJECTIVE To determine the clinical characteristics of gait disorders in patients with pontine medial tegmental lesions. DESIGN We compared features of gait disorders between patients with infarcts in the medial tegmentum and those with stroke in other areas of the pons (pathological control subjects) by measuring electromyographic results of lower limb muscles and several biomechanical param...

[Purpose] To measure electromyographic activity of the piriformis using fine-wire electrodes during 7 hip movements. [Subjects and Methods] Eleven healthy men, without severe low back pain or lower limb injury, participated in this study. Fine-wire electrodes were inserted into the piriformis and surface electrodes were attached to the muscles in the hip region and the trunk muscles on the domi...

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...
