The Phasic Electromyographic Metric (PEM) has been recently introduced as a sensitive indicator to differentiate Parkinson's Disease (PD) patients from controls, non-PD patients with a history of Rapid Eye Movement Disorder (RBD) from controls, and PD patients with early and late stage disease. However, PEM assessment through visual inspection is a cumbersome and time consuming process. Therefore, a reliable automated approach is required so as to increase the utilization of PEM as a reliable and efficient clinical tool to track PD progression. In this study an automated method for the detection of PEM is presented, based on the use of signal analysis and pattern recognition techniques. The results are promising indicating that an automatic PEM identification procedure is feasible.

The Role of Occlusal Appliances in Reducing Masseter Electromyographic Activity in Bruxism.
J Clin Med
November 2024
Department of Dental Prosthetics, University of Medicine and Pharmacy of Craiova, 200349 Craiova, Romania.
: Bruxism is a masticatory muscle activity, phasic or tonic, with/without teeth contact, that appears in sleep or an awake state. An instrumental technique used to measure the surface electromyographic (sEMG) activity of the masseter muscle is used to diagnose bruxism activity during sleep and while awake. The objective of this study was to compare the variation in bruxism (sleep and awake) indices and masseter activity indices in low sleep bruxism and moderate sleep bruxism before and after wearing an occlusal appliance (OA) for 3 months each night.

Reaching movements are essential for daily tasks and they have been widely investigated through kinematic, kinetic, and electromyographic (EMG) analyses. Recent studies have suggested that the central nervous system simplifies control of reaching movements by using muscle synergies. An alternative approach is to investigate how EMG activity reflects at theneural level with the representation of spinal maps that visualize the spatiotemporal activity of motoneuronal pools.

Article Synopsis
- The study investigates muscle atonia during REM sleep in patients with REM sleep behavior disorder (RBD) and narcolepsy to refine diagnostic criteria.
- Polysomnography recordings of 16 RBD patients, 15 narcolepsy patients, and 19 controls were analyzed, revealing specific electromyographic cut-off values for distinguishing these disorders.
- Results showed that RBD patients had significantly higher rates of REM sleep without atonia, particularly increasing in the second half of the night, unlike the relatively stable levels in narcolepsy patients.
Sleep Bruxism and Obstructive Sleep Apnea Are Not Risk Factors for Tension-Type Headache (TTH): A Polysomnographic Study.

Article Synopsis
- * A study involving 108 adults found that while the incidence of SB was lower in those with TTH compared to the control group, severe SB and overall sleep quality didn't significantly differ between the groups.
- * The findings suggest that neither OSA nor SB is a risk factor for TTH, and more research is needed to clarify their relationships, as TTH may not impact sleep structure.
Attentional focus differentially modulates the corticospinal and intracortical excitability during dynamic and static exercise.

Although attentional focus affects motor performance, whether corticospinal excitability and intracortical modulations differ between focus strategies depending on the exercise patterns remains unclear. In the present study, using single- and paired-pulse transcranial magnetic stimulation and peripheral nerve stimulation, we demonstrated changes in the cortical and spinal excitability under external focus (EF) and internal focus (IF) conditions with dynamic or static exercise. Participants performed the ramp-and-hold contraction task of right index finger abduction against an object (sponge or wood) with both exercises.
