We investigated the effects of forearm flexor/extensor muscles vibration on corticospinal excitability by means of transcranial magnetic stimulation (TMS) in healthy subjects. Motor evoked potentials (MEPs) and ongoing baseline activity of forearm flexor and extensor muscles were analyzed during muscle activity increase produced by vibration of these muscles (Tonic Vibratory Reflex) and by anta...

Forelimb trajectory and the activity of eight muscles operating at the elbow, wrist and digit joints were analyzed during contact placing (CP) reactions elicited by tactile stimuli applied to the lateral (L) or medial (M) side of the cat's forepaw to verify whether a common movement strategy was used in these reactions. A tactile stimulus applied to the lateral side of the paw led, most frequen...

This is an electromyographic study of the activity in flexor and extensor muscles of the big toe in 22 patients with a Babinski sign and 49 controls, after mechanical or electrical stimulation of the sole. The results indicate: (1) the Babinski sign is mediated by the extensor hallucis longus (EHL), and not by the extensor hallucis brevis; (2) electrical stimuli may fail to activate the EHL in ...

The objective is to find out the variant anatomy of muscles anterior compartment leg in human fetuses at 4-6 months.Material and methods. study was performed on 28 preparations 81.0-230.0 mm parietal-coccygeal length (PCL) using macro-microscopic preparation, morphometry statistical analysis.Results. structure topography 26 months revealed classic sites origin attachment, typical shape, number ...

OBJECTIVE It is known that patients in the intensive care unit show an enormous loss of muscle mass. Neuromuscular electrical stimulation is effective in enhancing strength and endurance in immobilized patients. The aim of this study was to evaluate the effects of neuromuscular electrical stimulation on muscle layer thickness of knee extensor muscles in intensive care unit patients. DESIGN Ra...

OBJECTIVE to identify the occupational factors associated with low back pain using a surveillance tool and to characterize the low back pain by the resistance of the extensor muscles of the vertebral column among nursing professionals at an Intensive Care Unit. METHODS Cross-sectional study. The workers answered a questionnaire about occupational factors and participated in a resistance test ...

OBJECTIVES The aim of this study was to evaluate the reliability and validity of a modified isometric dynamometer (MID) in performance deficits of the knee extensor and flexor muscles in normal individuals and in those with ACL reconstructions. METHODS Sixty male subjects were invited to participate of the study, being divided into three groups with 20 subjects each: control group (GC), group...

OBJECTIVE Although patients with diabetic peripheral neuropathy (DPN) are more likely to fall than age-matched controls, the underlying causative factors are not yet fully understood. This study examines the effects of diabetes and neuropathy on strength generation and muscle activation patterns during walking up and down stairs, with implications for fall risk. RESEARCH DESIGN AND METHODS Si...
