Effects of vibratory stimulation and maximal isometric contraction on a fine motor control task were evaluated in 17 human subjects. Electromyographic audiovisual feedback cues derived from two fine-wire bipolar electrodes, inserted to a depth of 12 and 6 mm respectively, were used to train the subjects to isolate a motor unit in the extensor carpi radialis(More)
The aim of this study was to assess the electromyographic (EMG) activity of the middle part of the deltoid and of the supraspinatus muscles in subjects suffering from supraspinatus tendinitis. This experimental group (N = 10) was compared to a control group (N = 10). Each subject performed three isometric contractions for each of four pre- determined levels(More)
BACKGROUND In patients undergoing primary percutaneous coronary intervention (PPCI) ticagrelor is superior to clopidogrel in reducing cardiovascular events. This study sought to evaluate the effect of clopidogrel pretreatment on the pharmacodynamics of ticagrelor in patients undergoing PPCI. METHODS We measured platelet reactivity using the VerifyNow(More)
OBJECTIVES Recent clinical trials suggest an LDL-independent superiority of intensive statin therapy in reducing target vessel revascularization and peri-procedural myocardial infarctions in patients who undergo percutaneous coronary interventions (PCI). While animal studies demonstrate that statins mobilize endothelial progenitor cells (EPCs) which can(More)
BACKGROUND The adoption of the transradial (TR) approach over the traditional transfemoral (TF) approach has been hampered by concerns of increased radiation exposure-a subject of considerable debate within the field. We performed a patient-level, multi-center analysis to definitively address the impact of TR access on radiation exposure. METHODS AND(More)
An EMG basic method of testing the fine motor control of the hand, a necessary clinical request, is needed to provide a practical approach on normal neuromuscular observations of the fine motor control parameters in order to interpret the harmonious motor functioning of the central and peripheral nervous systems. In this EMG study, predetermined voluntary(More)
The interpretation of neuromuscular impairment may be aided by an analysis of functional anatomic factors. The anatomy of the abductor pollicis brevis (APB), a muscle used for skilled movements, was investigated in 19 embalmed hands, and the muscular divisions joining the common tendon at different sites were reproduced on clear vinyl sheets. The median(More)
With the aid of electromyography, voluntary control of fine neuromuscular activity of deltoid and extensor digitorum communis muscles was studied in patients with motor dysfunction of the upper limb. A sequential training procedure was carried out both while the patient was wearing and not wearing a hand orthosis, during a static posture and dynamic hand(More)
