Accurate anatomical matching for patient-specific electromyographic (EMG) mapping is crucial yet technically challenging in various medical disciplines. The fixed electrode construction of multielectrode arrays (MEAs) makes it nearly impossible to match an individual's unique muscle anatomy. This mismatch between the MEAs and target muscles leads missing relevant activity, highly redundant data, complicated placement optimization, inaccuracies classification algorithms. Here, we present...
Interstitial cystitis/bladder pain syndrome patients can experience overactive pelvic floor muscle activity at rest. While the frequency power spectrum of has briefly been explored, intermuscular connectivity yet to be studied, which may provide useful insight into neurological component, ie, neural drive muscles, in interstitial syndrome.

The innervation zone asymmetry of the external anal sphincter (EAS) has been investigated as a risk factor for development fecal incontinence (FI). This study aims to utilize an intra-rectal high-density surface electromyogram (HD-sEMG) recording and advanced HD-sEMG decomposition technique characterize effects aging on EAS functional innervation.HD-sEMG signals were recorded intra-rectally from six healthy young seven elderly women during voluntary contractions EAS. EMG decomposed into...
Objective: The aim of this study is to compare the performance three strategies in determining global innervation zone (IZ) distribution. Methods: High-density surface electromyography was recorded from biceps brachii muscle seven healthy subjects under isometric voluntary contractions at 20%, 50%, and 100% maximal contraction supramaximal musculocutaneous nerve stimulations. IZs were detected: first, by visual identification a column-specific manner (IZ-1D); second, based on decomposed...
Several studies have shown interstitial cystitis/bladder pain syndrome (IC/BPS), a chronic condition that poses challenges in both diagnosis and treatment, is associated with painful pelvic floor muscles (PFM) altered neural drive to these muscles. However, its pathophysiology could also involve other alterations the electrical activity of PFM motor units (MUs). Studying provide novel insights into IC/BPS help clinical management. This study aimed characterize at MU level women myalgia using...
Abstract Objective . It is of great value to accurately localize innervation zones (IZs) better diagnose and treat neuromuscular diseases, but it challenging do so noninvasively from surface electromyography (sEMG) recordings because the blurring/distorting effect low conductive fat tissues. This study aimed develop an innovative transcutaneous IZ imaging (TIZI) technique precisely efficiently distribution directly over muscle in vivo high-density sEMG (HD-sEMG). Approach The TIZI was...
The prevalence of fecal incontinence (FI) increases with age and affects more than 15% the elderly population. Sarcopenia, skeletal muscle structural, functional decline aging, is known to be caused by neuromuscular dysfunction. However, age-related alterations function external anal sphincter (EAS) have not been studied. This study aims quantitatively characterize effect aging on EAS assessing firing patterns size motor unit action potential (MUAP) using high-density surface...
Previous studies have shown that beta-band transcranial alternating current stimulation (tACS) applied at the M1 hotspot can modulate corticospinal excitability. However, it remains controversial whether tACS influence motor unit activities spinal cord level. This study aims to compare efficacy of applying over versus conventional C3 site on and subsequent behavioral changes. used a randomized crossover trial design, where fifteen healthy participants performed paced ball-squeezing exercise...
Older adults with type II diabetes (T2D) are at risk of developing nerve disorders that result in functional impairment. Most work proprioceptive dysfunction older T2D has focused on deficits the lower limb. The purpose this study was to examine effects upper limb adults. Kinematic performance a reach-to-pinch action toward virtual target assessed group (60+ years old T2D) and healthy age- sex-matched control group. Tactile vibratory thresholds did not differ between controls. Task accuracy...
Interstitial cystitis/bladder pain syndrome (IC/BPS) can result in pelvic floor muscle (PFM) overactivity. Current clinical assessment protocols include basic electromyographic of PFM activation; however, they do not provide a comprehensive localized to each region the PFM. We examined ability high-definition features from intravaginal high-density surface electromyography (HD-sEMG) assess severity overactivity female IC/BPS patients. HD-sEMG was collected fifteen patients and urologically...

contrast, substantial muscle fiber attenuation and disorganization was observed in VD rats treated with saline or empty A-G-beads.CONCLUSIONS: IGF1-A-G-beads improved recovery a rat model of SUI, suggesting that these microspheres could provide local sustained delivery method for IGF-1.
INTRODUCTION AND OBJECTIVE: Pelvic floor hypertonicity (PFH) is a debilitating symptom of interstitial cystitis/bladder pain syndrome (IC/BPS). The diagnosis and assessment PFH are based on subjective pelvic examinations, results between examiners may vary. Precise critical to the clinical management PFH. objective this study provide innovative techniques objectively assess neurogenic in women with IC/BPS using an intra-vaginal high-density surface electromyography (HD-sEMG) probe.
