motor seizure

motor seizure

abnormal electrical activity that arises initially in a localized motor area of the cerebral cortex. The manifestations depend on the site of the abnormal electrical activity, such as tonic contractures of the thumb caused by excessive discharges in the motor area of the cortex controlling the first digit or chewing movements resulting from discharges in the lower part of the motor strip controlling mastication. The disturbance may spread, resulting in generalized convulsion, or it may end in a shower of clonic movements. See also epilepsy, focal seizure.

The duration of the motor seizure was recorded as the time from the ECT stimulus to the cessation of tonic-clonic motor activity in the 'isolated' arm; the duration was assessed by an observer through a window outside of the operating theatre to blind the observer to the anaesthetic agent used.

This definition implied that if a patient suffers a motor seizure that stops after 2 minutes but does not return to baseline before having another seizure, the continuing altered awareness would be included in the definition for treatment.
Motor seizure is a temporary disturbance in brain function caused by abnormal nerve signals that begin in a local motor nerve area of the brain.
A 70-year-old man presented with a left focal motor seizure followed by secondary generalized tonic-clonic seizure.
The duration of motor seizure was recorded as the time taken from the administration of the electrical stimulus to the cessation of the tonic-clonic activity in the isolated limb.
Motor seizure duration, electroencephalogram (EEG) seizure duration, and postictal suppression index (PSI) were recorded from the EEG and electromyography traces obtained during the seizure.
The unmodified motor seizure was also monitored using an isolated forearm technique.
Motor seizure duration was recorded as the time interval between ECT stimulus and cessation of tonic-clonic motor activity in the isolated upper limb, while EEG seizure duration was recorded as the interval between ECT stimulus and post-ictal EEG suppression.
