In order to study the influence of interelectrode distance and force level on the electromyographic (EMG) spectral parameters and on their reliability, bipolar surface EMG measurements were performed on the lumbar muscles of 15 subjects. Two test contractions (45 s) at 40% of maximal voluntary contraction (MVC) were performed, one with 2 cm interelectrode(More)
With the purpose of getting an overview of the current research and development in information systems and terminology for nursing practice and outline strategies for the future, an initiative for a workshop was taken at the national level in Sweden by the Section for Nursing Informatics, the Society of Nursing and the Association of Health Professionals in(More)
The recovery of the median frequency of the power spectrum of the electromyogram (EMG) after fatigue has been studied to obtain reference data for healthy subjects (n = 55). In a seated position, the subjects performed a 45 s isometric back muscle contraction at 80% of maximal voluntary contraction, followed by 5 s contractions after 1, 2, 3, and 5 min in(More)
