“…Park et al [ 12 ] reported that the thickness of SCM in B-mode ultrasound was well correlated with PROM of neck. In clinical settings, however, physicians encountered several infants who showed similar thickness of SCM, but different PROM of neck, like group 1S and 1M in current study.…”

“…The classifications of the severity of SCM fibrosis using B-mode ultrasound have been reported. [ 9 , 11 ] B-mode ultrasound was well correlated with PROM of neck, [ 12 ] and feasible as it can be quickly implemented in a clinical setting. But it is inevitably subjective, semiquantitative (imprecise), and prone to inter-observer error.…”

Congenital muscular torticollis (CMT) is characterized by shortening or excessive contraction of the sternocleidomastoid muscle (SCM). The main purpose of this study was to evaluate the feasibility of quantifying SCM stiffness using acoustic radiation force impulse (ARFI) sonoelastography in infants with CMT. Twenty infants with an SCM thickness greater than 10 mm with or without involvement of the entire SCM length (limitation of neck rotation passive range of motion [PROM]: group 1S >30°, group 1M = 15°−30°) and 12 infants with an SCM thickness smaller than 10 mm with or without involvement of any part of SCM (group 2) were included. The SCM thickness was measured using real time B-mode ultrasound, and the local SCM shear wave velocity (SWV) and subcutaneous fat layer using ARFI sonoelastography. The neck rotation PROM was significantly greater in group 1S (36.5° ± 5.3°) than in group 1M (18.8° ± 4.9°; P < .01); the SWV of the SCM in the affected side (2.96 ± 0.99 m/s) was significantly higher than that in the unaffected side (1.50 ± 0.30 m/s; P < .01) in group 1. The SWV of the SCM was significantly higher in group 1S than in group 1M. There was significant correlation between the degree of PROM deficit of neck rotation and the SWV of the affected SCM (r = .75; P < .01) in all infants. This study revealed a difference in the SWV of the affected SCM in relationship to the limitation of neck rotation PROM in infants with CMT, if there was no difference in SCM thickness among infants.

“…Congenital muscular torticollis (CMT) is a common congenital disorder in neonates and infants, showing incidence of 0.3% to 1.9% [ 28 - 30 ]. In previous studies, ultrasonographic findings showed focal or diffuse thickening in the lower two-thirds of the sternocleidomastoid muscle (SCM), with the size of the lesions ranging from 8 to 15.8 mm at the maximal transverse diameter and the length ranging from 13.7 to 45.8 mm [ 31 ].…”

“…However, there are some limitations in evaluating CMT using ultrasonography. First, the size of the SCM can decrease after physical therapy, which can affect its thickness and echogenicity [ 30 , 33 ]. In addition, the echogenicity and the maximum thickness of the SCM range widely, and for those demonstrating subtle changes, the diagnosis of CMT using ultrasonography can be challenging [ 31 - 34 ].…”

Usefulness of strain elastography of the musculoskeletal system

2016

Ultrasound elastography is a widely used technique for assessing the mechanical characteristics of tissues. Although there are several ultrasound elastography techniques, strain elastography (SE) is currently the most widely used technique for visualizing an elastographic map in real time. Among its various indications, SE is especially useful in evaluating the musculoskeletal system. In this article, we review the SE techniques for clinical practice and describe the images produced by these techniques in the context of the musculoskeletal system. SE provides information about tissue stiffness and allows real-time visualization of the image; however, SE cannot completely replace gray-scale, color, or power Doppler ultrasonography. SE can increase diagnostic accuracy and may be useful for the follow-up of benign lesions.

“…Ultrasound‐guided BoNT injections provide the most recent technique, which allows visualization of muscles, provides an atlas‐like observation, and also visualizes the diffusion of BoNT‐containing fluid out of the needle tip . Ultrasound‐guided injections are just beginning to be used in patients with CD or in pediatric patients . The combination of ultrasound and EMG is also possible, and dedicated probes are becoming available.…”

Therapeutic advances in dystonia

2015

Knowledge on dystonia has greatly improved recently, because of a renewed effort in understanding its cause, pathophysiology, and clinical characterization. Different drug classes traditionally have been used for the symptomatic treatment of dystonia, more recently surpassed by the introduction of botulinum neurotoxins and deep brain stimulation. No curative or disease-modifying treatments are available. Recent knowledge regarding the pathophysiology of inherited dystonias is highlighting new potential treatment strategies. We review therapeutic advances in dystonia that have been published over the last 3 years, particularly regarding oral medications, local injections of botulinum neurotoxins, deep brain stimulation, and transcranial or epidural brain stimulations. We discuss evidence of efficacy, highlight recent advances, and focus on key areas under development.
