Exteroceptive Reflexes in Stiff Person Syndrome, Other Neurological Conditions and Healthy Controls

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Stiff person syndrome (SPS) is a rare disabling neurological condition with overlapping symptomatology with more common neurological conditions. Exaggerated exteroceptive reflex mechanisms are thought to play a role in its pathophysiology.

Lower Urinary Tract Symptoms as Diagnostic Clues in Parkinsonism: A Practical Framework for Neurologists

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Lower urinary tract symptoms (LUTS) are among the most prevalent nonmotor complaints across the parkinsonian spectrum, yet they remain underutilized as diagnostic and management signals in neurology practice. Although prior reviews have characterized disease‐specific patterns of urinary dysfunction, and recent guidelines address ...

Defining the Clinical Phenotypic Ground Truth: Expert Interrater Agreement in Hyperkinetic Movement Disorders

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Reliable clinical phenotyping is crucial for diagnosis, treatment, and research in hyperkinetic movement disorders, yet its interrater reliability remains uncertain. Objectives To quantify interrater agreement in clinical phenotyping of hyperkinetic movement disorders among experts in a large, phenotypically diverse cohort.

Decoding Sleep Architecture from Ambulatory Basal Ganglia Signals in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Sleep architecture and circadian rhythms are frequently disrupted in Parkinson's disease (PD). BrainSense‐enabled neurostimulators combined with wearable technology enable chronic assessment of nocturnal brain activity, with potential for future diagnostics and personalized treatments. Objectives To neurophysiologically characterize

EMG Activity as a Function of the Performer's Focus of Attention

Journal of Motor Behavior, 2004
In previous studies of attentional focus effects, investigators have measured performance outcome. Here, however, the authors used electromyography (EMG) to determine whether difference between external and internal foci would also be manifested at the neuromuscular level.

Muscle motion and EMG activity in vibration treatment

Medical Engineering & Physics, 2009
The aim of this study is to highlight the relationship between muscle motion, generated by whole body vibration, and the correspondent electromyographic (EMG) activity and to suggest a new method to customize the stimulation frequency. Simultaneous recordings of EMG and tri-axial accelerations of quadriceps rectus femoris from fifteen subjects ...

EMG Activity in Response to Static and Dynamic Facial Expressions

International Journal of Psychophysiology, 2011
The EMG activity associated with static and dynamic facial expressions (morphs with happy or angry emotions) were compared. We hypothesized that dynamic faces would (a) enhance facial muscular reactions and (b) evoke higher intensity ratings. Our analysis showed that dynamic expressions were rated as more intense than static ones.

EMG Activity of the Muscular and Stromal Layer of the Cervix in Relation to EMG Activity of the Myometrium and Cervical Dilatation in PGF2α Induced Parturition in the Cow

Theriogenology, 2007
The goal of this study was to quantify and characterize the electromyographic (EMG) activities in the cervical outer muscular layer and in the cervical stromal layer, and to characterize their relationship with myometrial EMG activity and cervical dilatation during PGF2alpha-induced parturition in term pregnant cows.

Muscular activity and surface EMG

Journal of Biomechanics, 1985
In human movement, the skeletal muscles act as the active force elements. The force exerted by a muscle as well as the coordination of several muscles involved e. g. in a complex movement are controlled by the neural control of the muscles. A specific innervation pattern or program is transmitted from the CNS to the effectors via the axons and motor ...

Simulation of the Surface EMG of an Active Muscle

Biomedizinische Technik/Biomedical Engineering, 1998
A model of the motoneuronal (MN) pool-muscle system was developed. The model consists of four modules: (1) the input to the MN pool, (2) the MN pool, (3) the muscle and (4) the surface electromyogram (EMG). A control parameter activates the input fibers and determines the activity level of the muscle.
