    Abstract This study aimed to evaluate the usefulness, reliability, quality, and related characteristics of YouTube video clips on congenital muscular torticollis (CMT). This cross-sectional study analyzed 47 YouTube video clips on CMT. They were classified as either useful or misleading by 2 rehabilitation doctors. The modified DISCERN tool and the Global Quality Scale (GQS) were used to evaluate their reliability and quality. An analysis was conducted using the characteristics, such as presenters, ownership of YouTube channel accounts, countries, contents, and the video popularity. Of the 47 YouTube video clips, 8 (17%) were evaluated as misleading, which indicated that they included at least one scientifically unproven piece of information on CMT or more. They were less reliable and of lower quality than the useful video clips. The video clips presented by healthcare professionals were more useful compared to those presented by others (P = .015). However, the video popularity was not related to its usefulness. The reliability and quality (3.70 ± 0.82 vs 0.75 ± 0.50 and 2.95 ± 1.21 vs 1.50 ± 1.00) assessed by the modified DISCERN tool and GQS, respectively, were significantly higher in the video clips presented by healthcare professionals compared to those presented by others. There were misleading YouTube video clips on CMT. Video clips presented by healthcare professionals could be more useful, reliable, and of better quality. The popularity of the video clips does not indicate more usefulness, reliability, and better quality. YouTube viewers should be aware of these findings. We recommend that the viewers preferentially choose video clips on CMT presented by healthcare professionals, not by the video popularity.

    Abstract Objective: This study was to investigate ipsilateral hypertrophy of the mastoid process in the patients with congenital muscular torticollis (CMT).
    Design: Retrospective cross-sectional study.
    Patients: Children with CMT.
    Methods: A total of 212 surgical cases of patients with CMT (age: 50.9 ± 44.3 months) and 212 age- and gender-matched controls (age: 50.4 ± 44.2 months) were included. The mastoid process volume was calculated and compared for both groups on the computed tomography axial images. A linear regression analysis was performed between the age and the intrasubject volume difference in the mastoid process.
    Results: The volume of the mastoid process in the CMT side was significantly larger than that of the non-CMT side in the CMT group (32.2 ± 30.3 cm
    Conclusion: We showed ipsilateral hypertrophy of the mastoid process in patients with CMT and demonstrated that the volumetric asymmetry increased with age.

    Abstract Background: To determine whether there is an asymmetry in bilateral sternocleidomastoid muscle (SCM) thickness in patients with unilateral congenital superior oblique palsy (SOP) and its association with surgical results.
    Methods: The medical records of 186 patients with head tilt secondary to unilateral SOP, who were evaluated for the status of the SCM with neck ultrasound or magnetic resonance imaging, were reviewed. The SCM asymmetry index was calculated as a bilateral difference in the maximal muscle thickness divided by each tilted-side SCM thickness. The presence of SCM asymmetry, defined as an index of >10%, and its relationship to residual torticollis ≥5° after SOP surgery were assessed.
    Results: Of 186 patients with a median age of 1.2 years, SCM asymmetry was present in 102 (54.8%) patients (6.8 ± 1.9 mm for the SOP side vs. 6.6 ± 2.1 mm for the tilted side). The SCM asymmetry did not differ according to age, amount of head tilt or hypertropia. In the patients with SCM asymmetry, more patients (87.3%) underwent physiotherapy than those without asymmetry (61.9%) (P = 0.021). In 99 patients who underwent surgery for SOP, the resolution of torticollis was not significantly different between patients with and without SCM asymmetry (87.2% vs. 76.9%, P = 0.184).
    Conclusions: Nearly half of the patients with congenital SOP had SCM thickness asymmetry that was already determined at a young age. However, the surgical results did not differ significantly with respect to SCM asymmetry when physiotherapy was combined. Thus, SOP surgery can be considered despite preoperative SCM asymmetry.

    Abstract We analyzed whether macular superficial vascular density (SVD) and foveal vascular zone (FAZ) on optical coherence tomography angiography (OCTA) can distinguish between bilateral ametropic and anisometropic amblyopia. We included 42, 33, and 50 eyes in the bilateral ametropic amblyopia, anisometropic amblyopia, and normal control groups, respectively. Using macular swept-source optical coherence tomography angiography, we measured and analyzed the superficial FAZ areas and five sectoral macular SVDs after magnification correction. The anisometropic amblyopic eye group showed significantly increased foveal SVDs (p < 0.001) and significantly decreased superficial FAZ areas (p < 0.001), compared with the remaining groups. Additionally, the bilateral ametropic amblyopia group had significantly decreased nasal SVDs. SVDs and superficial FAZ areas differed among hyperopic amblyopia subtypes. These findings may reflect vascular distribution differences and macular changes in hyperopic amblyopia subtypes compared with normal eyes.

    Abstract Torticollis could be the only symptom and sign of craniovertebral junction (CVJ) abnormality. It could be difficult to identify CVJ abnormality as a cause of torticollis due to their rarity, especially for the subjects with torticollis caused by nontraumatic CVJ abnormalities. There has been no report to focus on nontraumatic CVJ abnormalities as a cause of torticollis. The objective of this study was to report 27 patients of torticollis caused by nontraumatic CVJ abnormalities, with the aim of helping clinicians to identify nontraumatic CVJ abnormalities as a cause of torticollis. This is a retrospective cohort study including 27 subjects who had torticollis caused by nontraumatic CVJ abnormalities. The CVJ was examined in terms of atlanto-occipital angle, atlanto-axial angle, and lateral and anterior atlanto-dens intervals for the evaluation of occipital condylar hypoplasia, rotation of atlanto-axial joint, and lateral and anterior shift of the dens, respectively. Abnormalities of the lower cervical or thoracic spine were also evaluated. Occipital condylar hypoplasia, rotation of atlanto-axial joint, and lateral shift of the dens were the most common CVJ abnormalities. The 18.5% of the subjects had concurrent anomalies of lower cervical or thoracic vertebrae along with CVJ abnormalities. Each subject had 2.22 ± 1.10 types of CVJ abnormalities on average. In conclusion, comprehensive evaluation of CVJ abnormalities is recommended for differential diagnosis of subjects with unexplained torticollis. Once CVJ abnormalities are identified, concurrent abnormalities of other vertebrae need to be evaluated.

    Abstract Background: Prone hip extension (PHE) has been investigated to strengthen the hip joint and back extensor muscles. However, it has not been compared with various PHE exercises in individuals with iliopsoas shortness.
    Objective: This study compared pelvic compensation and hip and back extensor muscle activities in individuals with iliopsoas shortness during prone hip extension (PHE) using the abdominal drawing-in maneuver alone (PHEA) and after iliopsoas stretching (PHEAS).
    Methods: Twenty-five individuals with iliopsoas shortness were included in the study. Electromyography was used to investigate bilateral erector spinae (ES) and ipsilateral gluteus maximus (GM), biceps femoris (BF), and semitendinosus (ST) muscles during PHE, PHEA, and PHEAS. Pelvic anterior tilting and rotation angles were measured during each PHE exercise via electromagnetic motion tracking. A modified Thomas test was used to examine the hip extension angle before and after iliopsoas stretching. One-way repeated-measures analysis of variance was used to investigate differences in pelvic anterior tilting and rotation angle and in hip and back extensor muscle activities among PHE, PHEA, and PHEAS. The level of statistical significance was set at α= 0.01.
    Results: GM muscle activity was significantly greater with PHEAS, compared to PHE and PHEA (p< 0.01). Bilateral ES and ipsilateral BF and ST muscle activities were significantly reduced with PHEAS, compared to PHE and PHEA (p< 0.01). Anterior pelvic tilting and rotation angles were significantly reduced with PHEAS, compared to PHE and PHEA (p< 0.01).
    Conclusions: PHEAS is recommended to selectively strengthen GM muscles with minimal BF and ST muscle activities and pelvic compensation in individuals with iliopsoas shortness. The abdominal drawing-in maneuver (ADIM) after iliopsoas stretching is more efficient than ADIM alone during PHE, especially in individuals with iliopsoas shortness.

    Abstract Background: This study aimed to analyze the literature systematically to determine the clinical characteristics and prognosis of patients with connective tissue disease (CTD) with combined pulmonary fibrosis and emphysema (CPFE) compared to those of patients with CTD-interstitial lung disease (CTD-ILD) without emphysema.
    Methods: We searched MEDLINE, EMBASE, Cochrane Library, and KoreaMed for relevant articles published before July 2019. Studies meeting all the following criteria were included: (1) original research studies evaluating the effect of CPFE on CTD, (2) studies that compared patients with CTD-CPFE to those with CTD-ILD without emphysema, and (3) studies providing data on physical capacity, pulmonary function, or death in patients with CTD. Clinical characteristics of patients with CTD-CPFE were compared with those of patients with CTD-ILD without emphysema, and the influence of CPFE on physical capacity, pulmonary function, and death was analyzed.
    Results: Six studies between 2013 and 2019 were included. Two hundred ninety-nine (29.5%) and 715 (70.5%) patients had CTD-CPFE and CTD-ILD without emphysema, respectively. Regarding the type of CTD, 711 (68.3%) patients had systemic sclerosis, 263 (25.3%) rheumatoid arthritis, and 67 (6.4%) other CTDs. Patients with CTD-CPFE had a higher frequency of pulmonary hypertension and pulmonary fibrosis > 20% of the total lung volume, higher ratio of the forced vital capacity to the diffusion capacity of the lung for carbon monoxide (DLCO), lower arterial oxygen pressure at rest, and lower DLCO compared to those in patients with CTD-ILD without emphysema. In addition, more deaths occurred among those with CTD-CPFE (odds ratio, 2.95; 95% confidence interval, 1.75-4.96).
    Conclusion: CTD-CPFE is associated with worse physical and pulmonary function and more deaths compared to those in CTD-ILD without emphysema. These findings indicate the need for increased awareness and close monitoring of patients with CTD-CPFE.

    Abstract Grisel syndrome is a rare, non-traumatic atlanto-axial subluxation associated with an inflammatory or infectious process in the upper neck. According to the two-hit hypothesis, which is widely accepted for the pathogenesis of Grisel syndrome, preexisting ligamentous laxity of the atlanto-axial joint is regarded as the first hit. An inflammatory or infectious process of the atlanto-axial joint acts as the second hit, resulting in non-traumatic atlanto-axial subluxation. We report on a 6-year-old girl with atlanto-axial subluxation following retropharyngeal and cervical lymphadenitis. She was diagnosed with Grisel syndrome, for which an initial computed tomography did not show any preexisting ligamentous laxity of the atlanto-axial joint. A literature review found only 4 case reports on Grisel syndrome with an initially normal atlanto-axial joint. The present case offers some evidence that a single hit, such as inflammatory changes in the atlanto-axial joint, might cause Grisel syndrome, even without underlying ligamentous laxity.
