    Summary: Over the past two decades, electrophysiology has undergone unprecedented changes thanks to technical improvements, which simplify measurement and analysis and allow more compact data storage. This book covers in detail the spectrum of electrophysiology applications in patients with disorders of consciousness. Its content spans from clinical aspects of the management of subjects in the intensive care unit, including EEG, evoked potentials and related implications in terms of prognosis and patient management to research applications in subjects with ongoing consciousness impairment. While the first section provides up-to-date information for the interested clinician, the second part highlights the latest developments in this exciting field. The book comprehensively combines clinical and research information related to neurophysiology in disorder-of- consciousness patients, making it an easily accessible reference for neuro-ICU specialists, epileptologists and clinical neurophysiologists as well as researchers utilizing EEG and event-related potentials. ℗ℓ

    Transcutaneous electrical nerve stimulation (TNS) was used on 20 patients with severe wrist pain due to rheumatoid arthritis. Three different stimulation frequencies were used: high 70 Hz stimulation (70 TNS), low frequency 3 Hz stimulation (3 TNS) and brief trains of stimuli with an internal frequency of 70 Hz and with a repetition rate of 3 Hz (3-70 TNS). The analgesic effect was evaluated on the patient's own estimate of pain relief and by means of a loading test in which the length of time the patient could hold a weight before and after TNS was used. The loading test and the patients' own estimate of pain relief corresponded well. After 70 TNS, 18 patients could double their loading time. The corresponding figure for 3-70 TNS was 16 patients and for 3 TNS 5 patients. The average duration of pain relief after cessation of stimulation was 18 h for 70 TNS and 15 h for 3-70 TNS, while those who responded to 3 TNS experienced pain relief for only 4 h on average.
