Physiological analysis of asterixis: silent period locked averaging.
نویسندگان
چکیده
Asterixis was studied in nine patients, using a new electrophysiological technique: silent period locked averaging (SPLA). There were two types of electromyographic (EMG) silence in the movements clinically judged as asterixis. The jerky movement in one of the two types might be caused by the silent period after the subclinical cortical myoclonus. SPLA would be useful for studying asterixis as well as other EMG silences.

Onset and offset of electromyographic (EMG) silence in asterixis.
The onset and offset of electromyographic (EMG) silence were studied physiologically by silent period locked averaging method (SPLA) combined with a computer-assisted method for detecting EMG changes in 11 patients with asterixis of various aetiologies. The onset followed the EMG discharge which was closely associated with a sharp wave probably generated by the motor cortex in three patients. N...
متن کاملPathophysiology of unilateral asterixis due to thalamic lesion.
OBJECTIVE Unilateral asterixis has been reported in patients with thalamic lesion. This study aims at elucidating the pathophysiology of the thalamic asterixis. METHODS Two cases with unilateral asterixis caused by an infarction in the lateral thalamus were studied by analysing the asterixis-related cortical activities, transcranial magnetic stimulation (TMS) for motor cortex excitability and...
متن کاملAsterixis as a Focal Neurologic Sign: Report of Three Cases and Literature Review
Asterixis, firstly described in metabolic encephalopathies, may occur unilaterally in patients with various focal brain diseases. Although hardly localizing, most reported cases have showed a contralateral thalamic pathology; but Lesions in the medial frontal lobe, parietal lobe, brain stem, basal ganglia, insular lesions, may also cause unilateral asterixis. In this article, three cases of acu...
متن کاملReaction-time binning: a simple method for increasing the resolving power of ERP averages.
Stimulus-locked, response-locked, and ERP-locked averaging are effective methods for reducing artifacts in ERP analysis. However, they suffer from a magnifying-glass effect: they increase the resolution of specific ERPs at the cost of blurring other ERPs. Here we propose an extremely simple technique-binning trials based on response times and then averaging-which can significantly alleviate the...
متن کاملA 5-year evaluation and results of treatment of chronic locked dislocations of the shoulder joint
Abstract Background: Chronic neglected dislocation of the shoulder joint can be defined as a neglected dislocation for more than a 3 week period. However, it has been shown that the negligence could range from a 24 hour period to 6 months1. Depending on age, signs, symptoms, etiology and types of dislocation, conservative treatment or surgical intervention could be considered. Methods: In t...
