REVIEW
L von Rohden, Julian H W Jürgens
BACKGROUND: The increasing number of treatable hereditary neuromuscular diseases in children requires a diagnostic tool that can quickly, safely, and noninvasively identify affected patients directly after birth or when showing initial clinical symptoms. With clinical analysis alone, this is very difficult. IMAGING MODALITY: Near-field sonography of skeletal muscles has gradually become established as a successful method over the last 35 years. METHODOLOGICAL INNOVATIONS: Examination is performed using a strictly standardized protocol in isotopic muscle regions and with standardized sections and application parameters...

BACKGROUND: Lumbar statilization exercise programs (LSEP) produce positive effects on clinical outcomes, but the underlying mechanisms remain fairly unexplored. Psychological and neuromuscular mechanisms can be involved such as a better activation of the lumbar multifidus which represents one possibility. OBJECTIVES: To determine the (1) effect of a LSEP on lumbar multifidus muscle thickness and activation, as measured with rehabilitative ultrasound imaging (RUSI), in patients with low back pain (LBP); (2) correlation between RUSI measures and any change in clinical outcomes following the LSEP; (3) reliability of RUSI measures in control subjects over 8 weeks...

Low-intensity ultrasound can be used for noninvasive neuromuscular stimulation to enhance the recovery of injured peripheral nerves and muscles. In order to improve the stimulation efficiency, focused ultrasound (FUS) with a high energy density should be used. Because the FUS is concentrated at a miniaturized focal area, deliberate targeting with focal depth control is required to achieve the accurate stimulation. In this study, a low-intensity focused ultrasound (LIFU) stimulator with a focal depth controller is presented as an effective ultrasound stimulation system for the neuromuscular rehabilitation...

Evidence suggests that critically ill children develop muscle wasting, which could affect outcomes. Muscle ultrasound has been used to track muscle wasting and association with outcomes in critically ill adults but not children. This review aims to summarize methodological considerations of muscle ultrasound, structural findings, and possibilities for its application in the assessment of nutrition and functional outcomes in critically ill children. Medline, Embase, and CINAHL databases were searched up until April 2016...

Anaphylaxis during anesthesia is an unpredictable, severe, and rare reaction. It has an incidence of 1/10 000 to 1/20 000 surgeries. In most series, the responsible drugs include neuromuscular blocking agents, latex, or antibiotics. The frequency and etiology of systemic allergic reactions in other medical procedures are largely unknown. The identification of responsible drugs of anaphylaxis is a complex task, requiring testing of all medications and substances used during surgery. We describe our experience in a retrospective study of 15 patients...

Ankle foot orthoses (AFOs) are designed to improve gait for individuals with neuromuscular conditions and have also been used to reduce energy costs of walking for unimpaired individuals. AFOs influence joint motion and metabolic cost, but how they impact muscle function remains unclear. This study investigated the impact of different stiffness AFOs on medial gastrocnemius muscle (MG) and Achilles tendon (AT) function during two walking speeds. We performed gait analyses for eight unimpaired individuals. Each individual walked at slow and very slow speeds with a 3D printed AFO with no resistance (free hinge condition) and four levels of ankle dorsiflexion stiffness: 0...

The abdominal draw-in maneuver (ADIM) is a method commonly used to reestablish neuromuscular control of the deep spine muscles among individuals with musculoskeletal problems. The purpose of this study was to evaluate the effect of ADIM combined with simulated weight-bearing (SWB) activities in the facilitation of the deep spine muscles. The subjects were 30 young healthy individuals. Ultrasound images were used to measure the relative changes in transverse abdominal (TrA), internal oblique (IO) and external oblique (EO) muscle thickness during a simulated weight-bearing ADIM (SWB-ADIM)...

A need exists for biomarkers to diagnose, quantify and longitudinally follow facioscapulohumeral muscular dystrophy (FSHD) and many other neuromuscular disorders. Furthermore, the pathophysiological mechanisms leading to muscle weakness in most neuromuscular disorders are not completely understood. Dynamic ultrasound imaging (B-mode image sequences) in combination with speckle tracking is an easy, applicable and patient-friendly imaging tool to visualize and quantify muscle deformation. This dynamic information provides insight in the pathophysiological mechanisms and may help to distinguish the various stages of diseased muscle in FSHD...

BACKGROUND: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is often associated with pelvic floor muscle spasm. While pelvic floor physical therapy (PFPT) is effective, some men are unable to resolve their symptoms and have residual trigger points (TPs). TP injection has been used for treatment in several neuromuscular pain syndromes. The objective of this study was to examine the efficacy and side effects of TP injection in men with CP/CPPS and pelvic floor spasm refractory to PT...

We examined the neuromuscular adaptations following 3 and 6 weeks of 80 vs. 30% one repetition maximum (1RM) resistance training to failure in the leg extensors. Twenty-six men (age = 23.1 ± 4.7 years) were randomly assigned to a high- (80% 1RM; n = 13) or low-load (30% 1RM; n = 13) resistance training group and completed leg extension resistance training to failure 3 times per week for 6 weeks. Testing was completed at baseline, 3, and 6 weeks of training. During each testing session, ultrasound muscle thickness and echo intensity, 1RM strength, maximal voluntary isometric contraction (MVIC) strength, and contractile properties of the quadriceps femoris were measured...
