Previous studies have explored to saturation the efficacy of the conventional signal (such as electromyogram) for muscle function assessment and found its clinical impact limited. Increasing demand for reliable muscle function assessment modalities continues to prompt further investigation into other complementary alternatives. Application of mechanomyographic signal to quantify muscle performa...

The aim of this study was to investigate the kinematical movements and electromyographic activities of the trunk and hip during trunk flexion and extension at different velocities. Thirteen male subjects performed trunk flexion and extension movements for 5 times at three different velocities of 1 s, 3 s, and 5 s in the standing position. Sagittal angular displacements of the lumbar spine, pelv...

BACKGROUND McConnell recommended that patellar tape be kept on all day, until patients learn how to activate their vastus medialis obliquus (VMO) during an exercise program. This application may pose problems because prolonged taping may be inadvisable for some patients or even contraindicated owing to skin discomfort, irritation, or allergic reaction. HYPOTHESIS Wearing patellofemoral tape f...

PRESENTATION An elderly man had recurrent hospital admissions with falls. OUTCOME Acetylcholine receptor antibodies and single-fibre electromyogram were useful in the diagnosis of myasthenia gravis. Treatment prevented further hospital admissions.

Friedberg's Triad is (1) measure the brain; (2) preempt the pain; (3) emetic drugs abstain. Persistent anesthesia problems include over- and under-medication, postoperative pain management, and postoperative nausea and vomiting. Inspired by Vinnik's diazepam-ketamine paradigm, Friedberg's propofol ketamine paradigm was first published in 1993. The 1997 addition of the bispectral (BIS) index bra...

The evoked electromyogram often decreases during anaesthesia in the absence of neuromuscular block. We have measured the electromyogram of the first dorsal interosseous muscle evoked by train-of-four stimulation of the ulnar nerve in 63 patients undergoing anaesthesia for minor surgery. We used Medicotest P-00-S electrodes, a Datex Relaxograph and a current sink in the stimulating leads in para...

[Purpose] Lower-limb deep vein thrombosis is a complication of orthopedic surgery. A leg-exercise apparatus named "LEX" was developed as a novel active-exercise apparatus for deep vein thrombosis prevention. Muscle activity was evaluated to assess the effectiveness of exercise with LEX in the prevention. [Subjects] Eight healthy volunteers participated in this study. [Methods] Muscle activities...

Functional electric stimulation is a new method for dynamic rehabilitation of paralyzed muscles. The output of such prosthetic devices needs to be modulated by some index of the muscle movement. In facial paralysis a measure of the muscle contractions of the normal contralateral side seems to be an appropriate input. In the rabbit, we simultaneously measured the compound action potential of the...

1. Failure of muscle force during sustained fatiguing contraction is associated with myoelectrical and metabolic alterations. However, the inter-relationships between these two types of events remain unclear. The purpose of this study was to examine the effects of decreased oxygen availability during sustained contraction on myoelectrical and metabolic changes, thereby addressing the issue of f...
