“…It has previously been suggested that increased muscle tension could be secondary to inflammation that acts via muscle spindles in muscle pain syndromes (38,39) or due to increased muscle nociception in tension type headaches (40). Neck muscle tension has previously been examined in migraine patients with EMG (41)(42)(43)(44)(45)(46)(47). Findings suggest that EMG activity is increased interictally in the cranial and upper cervical muscles during rest (41) and stressful mental tasks (42).…”

Findings suggest that EMG activity is increased interictally in the cranial and upper cervical muscles during rest (41) and stressful mental tasks (42). Studies have also reported increased activity in the extensors of migraine patients during neck flexion (43,44), and increased activity compared to the generated force (45).…”

Increased neck muscle stiffness in migraine patients with ictal neck pain: A shear wave elastography study

Background Ictal neck pain is a frequent symptom reported by half of migraine patients. It is unknown if neck pain is caused by peripheral or central mechanisms. Neck muscle stiffness can be investigated with ultrasound shear wave elastography. Objectives To determine if migraine patients with ictal neck pain have stiffer neck muscles interictally compared with patients without ictal neck pain and controls. Methods This was a cross-sectional study investigating neck muscle stiffness, pressure pain thresholds and neck pain symptoms in 100 migraine patients recruited from a tertiary headache center and 46 controls. Results Patients with ictal neck pain had increased mean neck muscle stiffness interictally compared to both migraine patients without ictal neck pain ( p = 0.018) and controls ( p = 0.036). Muscle stiffness was negatively correlated with pressure pain thresholds in the neck in migraine patients with ictal neck pain (r = −0.292, p = 0.042). There were no differences in mean pressure pain thresholds between migraine subgroups. Conclusions Migraine patients with ictal neck pain have stiffer neck muscles interictally compared with migraine patients without ictal neck pain and controls measured with ultrasound shear wave elastography. The increased stiffness could be due to local alterations in the neck muscles. Trial registration: clinical-trials.gov, identifier: NCT03626805

“…Additionally, as RELAX-Jr was assessed using a typically developing sample of children, its cleaning performance in clinical samples (e.g., autism, attention deficit hyperactivity disorder, epilepsy) remains to be established. We also note that lower density recordings, particularly those with <32 electrodes, could achieve significantly poorer performance resulting from insufficient ICA decomposition, which may not adequately separate neural from artifactual components (Janani et al, 2018;Klug & Gramann, 2021). For such recordings, the use of non-ICA based methods for data pre-processing should be considered.…”

Automated EEG pre-processing pipelines provide several key advantages over traditional manual data cleaning approaches; primarily, they are less time-intensive and remove potential experimenter error/bias. Automated pipelines also require fewer technical expertise as they remove the need for manual artifact identification. We recently developed the fully automated Reduction of Electroencephalographic Artifacts (RELAX) pipeline and demonstrated its performance in cleaning EEG data recorded from adult populations. Here, we introduce the RELAX-Jr pipeline, which was adapted from RELAX to be designed specifically for pre- processing of data collected from children. RELAX-Jr implements multi-channel Wiener filtering (MWF) and/or wavelet-enhanced independent component analysis (wICA) combined with the adjusted-ADJUST automated independent component classification algorithm to identify and reduce all artifacts using algorithms adapted to optimally identify artifacts in EEG recordings taken from children. Using a dataset of resting-state EEG recordings (N = 136) from children spanning early-to-middle childhood (4-12 years), we assessed the cleaning performance of RELAX-Jr using a range of metrics including signal-to-error ratio, artifact-to-residue ratio, ability to reduce blink and muscle contamination, and differences in estimates of alpha power between eyes-open and eyes-closed recordings. We also compared the performance of RELAX- Jr against four publicly available automated cleaning pipelines. We demonstrate that RELAX-Jr provides strong cleaning performance across a range of metrics, supporting its use as an effective and fully automated cleaning pipeline for neurodevelopmental EEG data.
