What is the observed percentage of seizure activity triggered by the Plainfield method in awake patients?

The Plainfield method is a technique used in the context of seizure monitoring and mapping in awake patients, particularly during procedures such as neurosurgical evaluations or intraoperative monitoring. The observed percentage of seizure activity triggered by this method is documented to be within the range of 20-25%. This figure reflects the effectiveness of the Plainfield method in eliciting and identifying seizure activity in patients who are awake, which is crucial for accurate localization of seizure foci and planning subsequent medical or surgical interventions.

In awake patients, the ability to stimulate areas of the brain while the patient is conscious allows for a more precise assessment of brain functions and the potential impact of seizures. The 20-25% range indicates a notable frequency of activity that can be observed under controlled conditions, which is particularly important for ensuring targeted treatment strategies that minimize disruption to critical brain functions.

The other ranges provided do not reflect the current data on the efficacy of the Plainfield method in terms of seizure activity observation in awake patients. The established range of 20-25% underscores the method's relevance and utility in neurophysiological assessments.
