The diagnosis and evaluation of neuromuscular disorders traditionally involves electrodiagnostic (EDx) testing, including nerve conduction studies (NCSs) and electromyography (EMG). These tools can cause pain and discomfort, an important consideration when performed on children. Neuromuscular ultrasound is noninvasive, cost-effective, and increasingly utilized for the detection of neuromuscular pathology. Studies investigating the performance and clinical implementation of ultrasound have primarily been performed in adult populations. Ultrasound in children has the potential to guide EDx testing and ultimately improve diagnostic efficiency and accuracy. This review aims to describe key features of neuromuscular ultrasound in the pediatric population based on the available studies, including our own institutional experience.

Unlabelled: Congenital titinopathy has recently emerged as one of the most common congenital muscle disorders.
Objective: To better understand the presentation and clinical needs of the under-characterized extreme end of the congenital titinopathy severity spectrum.
Methods: We comprehensively analyzed the clinical, imaging, pathology, autopsy, and genetic findings in 15 severely affected individuals from 11 families.

The study aimed to identify expert opinions and obtain recommendations on the management of post-stroke hemiplegic shoulder pain (HSP) and treatment with botulinum toxin A (BoNT-A). A multicenter Delphi study was conducted using an online survey designed by a committee of experts with at least 10 years of experience in post-stroke HSP management with BoNT-A in Spain. Forty-seven panelists (specialists with at least 5 years of experience in post-stroke HSP management with BoNT-A) rated their level of agreement in two rounds based on acceptance by ≥66.

Competitive alpine skiing requires a high level of physical fitness to perform sport-specific manoeuvres and to minimise the risk of injury. The aim of this study was to establish reference values for the maximal anatomical cross-sectional area (ACSA) of the individual hamstrings (HAM) and quadriceps (QUAD) muscles as well as for the maximal voluntary torque (MVT) during knee flexion (KF) and knee extension (KE) of female and male elite competitive alpine skiers. Ultrasound and dynamometer data were obtained from a largely overlapping but not identical dataset.

Introduction: Proprioceptive neuromuscular facilitation (PNF) stretching is widely used to increase range of motion, but its underlying mechanisms are not well understood. This experimental, parallel group design study investigated the acute effects of PNF stretching on rectus femoris muscle stiffness and explored a potential dose-response relationship.
Methods: Thirty healthy young adults (23 females, 7 males) were randomly assigned to either a PNF stretching group (n = 15; 22.

Biallelic pathogenic variants in cause a fatal autosomal recessive multisystem disorder characterized by recurrent autoinflammation, hypomyelination, progressive neurodegeneration, microcephaly, failure to thrive, liver dysfunction, respiratory chain defects and accumulation of glycogen in skeletal muscle. No missense variants in have been reported to date.We report a 6-year-old boy with microcephaly, global developmental delays, lower limb spasticity with hyperreflexia, epilepsy, abnormal brain MRI, failure to thrive, recurrent fevers and transaminitis.
