Article Synopsis
- Clinical rating scales often miss the full range of dystonic symptoms, prompting the need for a reliable biomarker to assess the effectiveness of deep brain stimulation (GPi-DBS) for treating dystonia.
- In a study of 12 patients undergoing GPi-DBS, researchers found that those with arm dystonia had higher intermuscular coherence in the 4-12 Hz range before surgery, which significantly decreased after the procedure.
- Despite the observed changes in coherence, the study found no strong links between coherence levels and clinical rating scale scores, suggesting that more research is needed to determine the biomarker's clinical utility.
Background And Purpose: Tremor is a frequent complaint of solid organ transplant recipients. We report on the largest population investigated with clinical neurophysiological methods. Our aim is to objectively establish the tremor prevalence and syndrome in the largest population of solid organ transplant recipients.

Electrophysiology can help differentiate between these subtypes; however, the diagnostic value of several features is largely unknown.
Objective: This study aims to determine the diagnostic value of the burst duration in distinguishing CM and NCM.
Background: Increased 4-12 Hz oscillatory activity in the cortico-basal ganglia-thalamo-cortical (CBGTC) loop is reported in dystonia. Coherence analysis is a measure of linear coupling between two signals, revealing oscillatory activity drives that are common across motor units. By performing coherence analysis, activity of the CBGTC-loop can be measured with modalities like local field potentials (LFPs), electromyography (EMG), and electro-encephalography (EEG).

TCD is frequently used to monitor aneurysmal subarachnoid hemorrhage (aSAH) patients. This study compares TCD-criteria for vasospasm and its association with Delayed Cerebral Ischemia (DCI).
