Article Abstract
Neuromuscular conduction dysfunction-induced underactive bladder (UAB) is a major urological complication associated with diabetes mellitus (DM), and there remain deficiencies in reliable pharmacological treatment options. Astragalus polysaccharides (APS), as an edible active substance in , have a therapeutic effect on diabetes and its complications. We investigated the effects and mechanism of APS in high-fat-diet-induced (HFD) diabetic UAB mice. APS significantly reduced fasting plasma glucose, insulin, and HOMA-IR index. Furthermore, APS treatment significantly decreased maximum bladder capacity, residual volume, bladder compliance, contraction intervals, empty and full resting pressure, and increased voiding volume and voided efficiency. In addition, APS ameliorated the hyporesponsiveness of purinergic and cholinergic-mediated neuromuscular contraction of the detrusor and improved the dysregulation of inhibitory and excitatory neurotransmission by downregulating the levels of nNOS and VIP, and upregulating ChAT and SP in HFD mice. This study revealed that APS ameliorates diabetic UAB via the normalization of neuromuscular conduction.

Objectives: To describe the main features and the clinical management of a cohort of patients with immune-mediated necrotizing myopathy (IMNM).
Methods: We conducted an observational, monocentric, retrospective study of IMNM patients diagnosed in the Neuromuscular Unit of a tertiary hospital in Madrid (Spain) between 2013 and 2021.
Results: Sixteen IMNM cases were diagnosed, with a median age of 71.
Risdiplam and nusinersen in spinal muscular atrophy: a descriptive real-world study on motor function outcomes in northwestern Iran.

Spinal muscular atrophy (SMA) types 2 and 3 are chronic neuromuscular disorders characterized by progressive motor impairment. Although disease-modifying therapies such as risdiplam and nusinersen have shown clinical efficacy, real-world data in pediatric populations remain limited. This prospective observational study evaluated motor function outcomes in 20 children with SMA (aged 3 to 13 years; 12 with type 2, 8 with type 3) receiving either risdiplam or nusinersen in Northwestern Iran.

Objective: High-density surface electromyography (HD-sEMG) is a non-invasive and quantitative tool for studying neuromuscular disorders, enabling assessments of muscle excitation, motor unit (MU) characteristics and firing patterns. This systematic review reports the published evidence on the clinical applications of HD-sEMG across neuromuscular disorders, identifying the range of disorders studied, indexes utilized, and gaps in the literature.
Methods: Systematic searches in PubMed and Scopus identified 200 studies, of which 55 met the inclusion criteria.
Exploring the role of ankle torque fluctuations and intramuscular coherence in gait function among older adults.

Division of Rehabilitation Sciences, Department of Health Sciences, Medical School, Nagoya City University, Nagoya, Japan.
Objective: This study aimed to investigate the relationship between ankle joint function and walking performance in older adults by assessing qualitative ankle functions through torque fluctuation analysis and tibialis anterior (TA) intramuscular coherence during isometric dorsiflexion.
Methods: Thirty-eight community-dwelling older adults participated in this study. Ankle torque fluctuations and intramuscular coherence were evaluated during a dorsiflexion task at 30% of maximum voluntary torque (MVT).

Fatigability refers to the inability of the neuromuscular system to generate enough force to produce movements to meet task challenges. Fatigability has a central and a peripheral component linked via the neuromuscular system, but how these two components interact as fatigue develops lacks a complete understanding. The effects of fatigability are experienced in healthy humans but also accompany various disorders, often exacerbating their symptoms.
