Voluntary contractions induce thixotropic changes in intrafusal muscle fibres and hence, by induction or removal of "slack", the background discharge and sensitivity of spindle endings to stretch is altered. This study assessed whether such changes also altered the "excitability" of the motor cortex. Eleven subjects performed a series of voluntary(More)
BACKGROUND The ability to detect sinusoidal vibrations on the skin surface is dependent on the activation of two classes of receptors. The density of such receptors varies across the skin surface and is a factor in determining the sensory acuity of each skin area. However, the acuity of many sensory systems is known to deteriorate with advancing age. The(More)
AIMS AND OBJECTIVES To explore which medications Australian nurse practitioners most frequently prescribe. BACKGROUND Although nurse practitioners in Australia have prescriptive authority, little is known about which specific medications nurse practitioners are prescribing and how frequently they do so. DESIGN Descriptive electronic survey. METHODS A(More)
A number of human and animal studies have reported a differential representation of the frequency of vibrotactile stimuli in the somatosensory cortices: neurons in the primary somatosensory cortex (SI) are predominantly responsive to lower frequencies of tactile vibration, and those in the secondary somatosensory cortex (SII) are predominantly responsive to(More)
BACKGROUND Inter-professional learning has been promoted as the solution to many clinical management issues. One such issue is the correct use of asthma inhaler devices. Up to 80% of people with asthma use their inhaler device incorrectly. The implications of this are poor asthma control and quality of life. Correct inhaler technique can be taught, however(More)
Modulation of ongoing electromyographic (EMG) activity in the small hand muscles can be induced by electrical stimulation of the digital nerves or by stimulation of the skin of the fingers. Several groups have attempted to establish a role for the motor cortex in the generation of the facilitatory component of the cutaneomotor reflex. Our aim was to(More)
PURPOSE The purpose of this study was to investigate the sources, both print and electronic formats, which Australian nurse practitioners (NPs) currently use to obtain information regarding quality use of medicines (QUM). An additional aim was to document NPs' preferences for continuing education in relation to QUM. DATA SOURCES A national electronic(More)
