The role of congenital muscular torticollis in the development of deformational plagiocephaly

Risk Factors for Delayed Diagnosis of Positional Plagiocephaly: A Review of 25,322 Patients

OBJECTIVE

This study identifies risk factors for late positional plagiocephaly (PP) diagnosis and impact on helmet therapy.

DESIGN

We conducted a retrospective review of all patients diagnosed with PP over 10 years at five Southern California hospitals.

SETTING

Patients diagnosed with PP at an included hospital.

PATIENTS

25,332 patients were diagnosed with PP over 10 years.

INTERVENTIONS

Patients diagnosed with PP early (< = 6 months) and late (>6 months) were compared.

MAIN OUTCOME MEASURES

Cohorts were evaluated for demographics, gestational history, associated conditions, and hospitalizations through direct comparison, logistic regression, and correlation analyses. Rates of referrals and helmet orders were compared.

RESULTS

Of patients reviewed, 4.8% (n  =  1216) were diagnosed late. On multivariate analysis, late diagnoses were more likely Hispanic or Black/African-American. Early gestational age, hydrocephalus, and VP shunt were more frequent in late diagnoses. Patients diagnosed late had longer NICU and overall hospital stays. Earlier gestational age, longer NICU or overall hospital stay correlated with later age at PP diagnosis. 8.9% of patients were referred for helmet therapy evaluation. Patients diagnosed late were 2.63 and 1.64 times as likely to be referred and require helmet therapy, respectively.

CONCLUSIONS

Patients who are Hispanic or Black/African-American, premature, have hydrocephalus, or VP shunt have higher rates of delayed PP diagnosis. Shorter gestational age or longer NICU or hospital stay correlates with later diagnosis, which increases helmet therapy requirements. Additional interventions are needed for at risk patients to routinely evaluate for and minimize the risk of developing PP.

Positional Plagiocephaly Side and Neurodevelopmental Delay: Study on 408 Infants

OBJECTIVE

Provide data on a cross-sectional study of neurodevelopmental delays in positional plagiocephaly (PP) based on severity and flattening side on early childhood patients.

METHODS

Neurodevelopment of 408 PP in patients with an age range of 3 to 59 months was assessed with Battelle Developmental Inventory (BDI) tests during and after their cranial orthotic treatment. Data obtained were compared with the cranial anthropometric measurements taken the same day the test was made, and results were segregated by flattening side, grouped by diagnosis and severity, segmented by age group, and split by sex.

RESULTS

From 3983 patients with positional skull deformities and simple craniosynostosis, 526 patients accepted to participate and took a total of 1261 BDI tests. Premature, patients with neurological diseases, cranial malformations, tests taken when positional skull deformity was corrected, and tests without plagiocephaly were excluded. The resulting database was made of 408 PP patients (300 boys and 108 girls) and 883 BDI tests (345 with left-side plagiocephaly and 538 with right-side plagiocephaly). Significant neurodevelopmental delay in more than one BDI domain on left-side plagiocephaly tests is observed in 76.4% of female and 92.2% of male patients and on right-side plagiocephaly tests in 75.5% of female and 95.5% of male patients. Neurodevelopmental delay difference between flattening sides, when both plagiocephaly sides presented significant delays, ranges from 0.2 to 3 months (BDI domain fine motor, Cephalic Index range ≥85 <100; BDI communication, age group 18-23).

CONCLUSION

Neurological delay may vary depending on plagiocephaly side, thus when evaluating plagiocephaly patients the flattening side should be noted.

Clinical Application of Custom Neck Collar with Negative Sensory Feedback in Children with Intractable Torticollis

BACKGROUND/OBJECTIVES

The aim of this study was to investigate the effect of a custom neck collar with negative sensory feedback for the treatment of torticollis that was previously unresponsive to conservative or surgical treatment.

METHODS

Twenty-four children diagnosed with unresponsive or intractable torticollis were enrolled in this two-stage, single-arm study. The ipsilateral aspect of the orthosis is adjustable in height and designed to provide support between the clavicle and the mandibular angle on the tilted side. In stage 1 (the adjustment period), the orthosis with a smooth surface was applied for 2 h per day for 3 months. In stage 2, a rough surface with a hook-and-loop fastener (Velcro©) was attached to the collar, and it was worn for a further 2 h a day for 3 months. Twenty children (mean age 63.95 ± 13.44 months) were included in the analysis.

RESULTS

The mean torticollis angle was 17.60 ± 5.65° (mean ± SD) at baseline; 14.15 ± 3.62° directly after stage 1; and 6.00 ± 3.67° directly after stage 2 (X2 = 36.685, df = 19, p = 0.000).

CONCLUSIONS

This study demonstrated the feasibility, therapeutic effect, and safety of a novel tactile feedback orthosis for the treatment of children with torticollis. The use of a custom neck collar with negative sensory feedback may be a viable therapeutic option for the treatment of unresolved or intractable torticollis.

Comorbidities of deformational plagiocephaly in infancy: A scoping review

AIM

While deformational plagiocephaly (DP) is suspected to be associated with comorbidities, their nature and prevalence are unclear. This scoping review aims to report DP comorbidities occurring until the age of 2 years, their prevalence and whether they depend on the child's age and sex.

METHODS

Relevant studies were identified by searching the Cochrane, MEDLINE, EMBASE, PubMed and EBSCO databases from 1992 to 30 April 2021. Data on study characteristics, comorbidities and assessment instruments were extracted and qualitatively synthesised. Risk of bias was assessed and studies with high risk of bias were excluded.

RESULTS

Studies meeting selection criteria (n = 27) often evaluated groups from tertiary clinics, implying selection bias. Studies reported on developmental delay (n = 16), limited speech production (n = 1), auditory (n = 3), visual (n = 3), mandibular (n = 3) and neurological impairments (n = 1). The data did not allow prevalence calculation or modifying effect of sex. Due to biased data, the review provided no evidence on DP comorbidities. Weak evidence suggested that in the selective samples, DP was associated with motor and language delays in the first year.

CONCLUSION

Due to biased data, no evidence on comorbidity in infants with DP was available. Our study underlined the need of risk of bias assessment in scoping reviews.

Another look at “tummy time” for primary plagiocephaly prevention and motor development

It is three decades since it was recommended that infants sleep on the back to reduce risk of sudden unexpected infant death (SUID). The SUID prevention program is known as "back to sleep" or "safe sleeping", and this initiative is not questioned. Sleeping on the back is associated with, but not the cause of, the development of infant positional plagiocephaly, also known as deformational or a non-synostotic misshapen head when the skull sutures are open, not fused. This paper provides a synthesis of the history and impact of positional plagiocephaly. It includes a scoping review of plagiocephaly prevention facilitating motor development and reveals few articles on primary prevention which aims to prevent it developing in the first place. It is concerning that preschool-aged children with a history of infant plagiocephaly continued to receive lower developmental scores, particularly in motor development, than unaffected controls, and this may be a marker of developmental delay. Tummy-time (prone) for play is the mainstay of plagiocephaly prevention advice to minimize development of plagiocephaly and to facilitate infant motor development, particularly head control. While tummy-time has shown benefit for infant development, there is limited evidence of its effectiveness in preventing plagiocephaly and some evidence that it promotes only prone-specific motor skills. Most of the published literature is concerned with treatment post-diagnosis, in the form of reviews, or clinical notes. There is a plethora of opinion articles reinforcing tummy-time from birth for plagiocephaly prevention. The review shows that there are gaps in advice for early infant development of head control. An accepted test of head control in infants is "pull to sit" from supine which demonstrates antigravity strength of the neck flexors and coordination of the head and neck when the infant is drawn to sit from supine. This motor skill was cited as achievable by 4 months in the earliest paper on plagiocephaly in 1996. Physical therapists and others should revisit the mechanism of early infant head control development against gravity, particularly antigravity head, neck and trunk coordinated flexion movement in supine, as there has been little attention to early facilitation of this motor skill as a plagiocephaly prevention strategy. This may be achieved by considering "face time" as well as tummy time for primary prevention of plagiocephaly.

New insights in pediatrics in 2021: choices in allergy and immunology, critical care, endocrinology, gastroenterology, genetics, haematology, infectious diseases, neonatology, neurology, nutrition, palliative care, respiratory tract illnesses and telemedicine

In this review, we report the developments across pediatric subspecialties that have been published in the Italian Journal of Pediatrics in 2021. We highlight advances in allergy and immunology, critical care, endocrinology, gastroenterology, genetics, hematology, infectious diseases, neonatology, neurology, nutrition, palliative care, respiratory tract illnesses and telemedicine.

Torticollis in childhood-a practical guide for initial assessment

Torticollis is encountered often in the paediatric setting and should be considered a presenting symptom, rather than a diagnosis. Aetiologies of torticollis are numerous, and the nomenclature describing underlying diagnosis can be confusing. Furthermore, children with torticollis typically present in the first instance to primary or secondary care rather than to the subspecialist. These factors can contribute to erroneous treatment of this patient-group which could be time critical in some instances. In this review, we discuss the common causes for torticollis and propose a simple clinical assessment tool and early management scheme that will assist in the differential-diagnosis and treatment pathway of this challenging condition.Conclusion: Torticollis can be the initial presentation of various conditions. The diagnosis and management tools provided in this article can aid in guiding paediatricians as to the correct initial management, imaging, and specialist referral. What is Known: • Torticollis in childhood is a very common presenting symptom with numerous aetiologies. • Management is complex, requires multiple clinical and imaging examinations, and is usually performed by non-specialized professionals. What is New: • A new, simple clinical-assessment tool under the acronym PINCH designed to aid paediatric general practitioners in diagnosing correctly the aetiology of torticollis. • A practical management scheme to aid in the treatment pathway of children with torticollis.

Active Cervical Range of Motion in Babies with Positional Plagiocephaly: Analytical Cross-Sectional Study

Positional plagiocephaly (PP) is a general term describing cranial distortion from pre- or postnatal forces on the infant head. Abnormal intrauterine forces, multiple births, primiparous mothers, obstetric interventions, prematurity, male sex, excessive time lying in the supine position, and mobility restrictions of the cervical spine have been considered as the main predisposing factors. The objective was to investigate the association between the severity of PP and the active cervical rotation and to analyze the influence of predisposing factors in babies with PP. An analytical cross-sectional study was performed on 74 babies with moderate PP. Clinical and demographic data, cranial vault asymmetry, and active cervical rotation range of motion (ROM) were measured. Associations were analyzed with generalized linear models. The mean age was 16.8 ± 5.0 weeks, and 56.8% were male. A restriction in the ROM of active cervical rotation, especially to the left side, was observed. Our models showed that cranial asymmetry was related with left active cervical rotation ROM (p = 0.034) and with being transported in a pushchair (p < 0.001). Conclusions: An increased severity of PP was related with being transported in a baby pushchair and with a reduced active cervical rotation ROM toward the most restricted side.

Efficacy of pediatric integrative manual therapy in positional plagiocephaly: a randomized controlled trial

BACKGROUND

Positional plagiocephaly frequently affects healthy babies. It is hypothesized that manual therapy tailored to pediatrics is more effective in improving plagiocephalic cranial asymmetry than just repositioning and sensory and motor stimulation.

METHODS

Thirty-four neurologically healthy subjects aged less than 28 weeks old with a difference of at least 5 mm between cranial diagonal diameters were randomly distributed into 2 groups. For 10 weeks, the pediatric integrative manual therapy (PIMT) group received manual therapy plus a caregiver education program, while the controls received the same education program exclusively. Cranial shape was evaluated using anthropometry; cranial index (CI) and cranial vault asymmetry index (CVAI) were calculated. Parental perception of change was assessed using a visual analogue scale (- 10 cm to + 10 cm).

RESULTS

CVAI presented a greater decrease in PIMT group: 3.72 ± 1.40% compared with 0.34 ± 1.72% in the control group (p = 0.000). CI did not present significant differences between groups. Manual therapy led to a more positive parental perception of cranial changes (manual therapy: 6.66 ± 2.07 cm; control: 4.25 ± 2.31 cm; p = 0.004).

CONCLUSION

Manual therapy plus a caregiver education program improved CVAI and led to parental satisfaction more effectively than solely a caregiver education program.

Effectiveness of pediatric integrative manual therapy in cervical movement limitation in infants with positional plagiocephaly: a randomized controlled trial

BACKGROUND

Positional plagiocephaly (PP) is a cranial deformation frequent amongst children and consisting in a flattened and asymmetrical head shape. PP is associated with excessive time in supine and with congenital muscular torticollis (CMT). Few studies have evaluated the efficiency of a manual therapy approach in PP. The purpose of this parallel randomized controlled trial is to compare the effectiveness of adding a manual therapy approach to a caregiver education program focusing on active rotation range of motion (AROM) and neuromotor development in a PP pediatric sample.

METHODS

Thirty-four children with PP and less than 28 week-old were randomly distributed into two groups. AROM and neuromotor development with Alberta Infant Motor Scale (AIMS) were measured. The evaluation was performed by an examiner, blinded to the randomization of the subjects. A pediatric integrative manual therapy (PIMT) group received 10-sessions involving manual therapy and a caregiver education program. Manual therapy was addressed to the upper cervical spine to mobilize the occiput, atlas and axis. The caregiver educational program consisted in exercises to reduce the positional preference and to stimulate motor development. The control group received the caregiver education program exclusively. To compare intervention effectiveness across the groups, improvement indexes of AROM and AIMS were calculated using the difference of the final measurement values minus the baseline measurement values. If the distribution was normal, the improvement indexes were compared using the Student t-test for independent samples; if not, the Mann-Whitney U test was used. The effect size of the interventions was calculated using Cohen's d.

RESULTS

All randomized subjects were analysed. After the intervention, the PIMT group showed a significantly higher increase in rotation (29.68 ± 18.41°) than the control group (6.13 ± 17.69°) (p = 0.001). Both groups improved the neuromotor development but no statistically significant differences were found. No harm was reported during the study.

CONCLUSION

The PIMT intervention program was more effective in increasing AROM than using only a caregiver education program. The study has been retrospectively registered at clinicaltrials.gov, with identification number NCT03659032 . Registration date: September 1, 2018.

A Quantitative Analysis of Facial Asymmetry in Torticollis Using 3-Dimensional Photogrammetry

OBJECTIVE

To assess whether children with torticollis have quantifiably greater facial asymmetry than their age-matched controls using 3-dimensional (3D) photogrammetry.

DESIGN

We retrospectively analyzed patients diagnosed with torticollis and age-matched volunteers who underwent 3D photogrammetry of their faces. We calculated the root mean square deviation (RMSD) between native and reflected facial images, as a measure of asymmetry. Two observers independently measured RMSD values for all study participants. The Spearman correlation coefficient evaluated interobserver reliability. The Wilcoxon rank-sum test with Bonferroni adjusted P values for multiple comparisons.

SETTING

Institutional.

PARTICIPANTS

Twenty patients diagnosed with torticollis and 12 age-matched volunteers. Patients were analyzed on a computer database and volunteers were selected and consented in the hospital. We excluded patients with a history of facial trauma, facial operations, or other craniofacial diagnoses.

INTERVENTIONS

Facial surface scans were obtained using the Canfield Vectra stereophotogrammetry system. The technology captures surface anatomy without radiation.

MAIN OUTCOME MEASURES

RMSD comparisons between patients with torticollis and age-matched controls.

RESULTS

Compared to controls, patients with torticollis had statistically significant greater full face, upper third, and middle third facial asymmetry. There was a trend toward greater asymmetry of the lower facial third.

CONCLUSIONS

We used 3D photogrammetry to quantitate facial asymmetry from torticollis. We found greater asymmetry in patients with torticollis than in their unaffected peers. All areas of the face appeared to be affected, though the asymmetry in the lower facial third just failed to reach significance.

Congenital muscular torticollis: the reliability of visual estimation in the assessment of cervical spine active rotation and head tilt by physiotherapists and the impact of clinical experience

There is a lack of reliable and valid measurement tools to assess neck function in infants with congenital muscular torticollis, and most physiotherapists use visual estimation, which has not been adequately tested for reliability in this population. We examined the reliability of visual estimation of head tilt and active neck rotation in the upright position, on infants with congenital muscular torticollis by physiotherapists. We recruited 31 infants and 26 physiotherapists. Therapists rated videos of infants' head position in the frontal plane (tilt) and transverse plane (active rotation) using visual estimation, on two occasions at least one week apart. Overall, inter-rater reliability was good (mean ICC, 0.68 ± 0.20; mean SEM, 5.1° ± 2.1°). Rotation videos had better reliability (mean ICC, 0.79 ± 0.14) than head tilt videos (mean ICC, 0.58 ± 0.20). Intra-rater reliability was excellent (mean ICC, 0.85 ± 0.08). Both head tilt and rotation had excellent reliability (mean ICC, 0.84 ± 0.08 for head tilt and 0.85 ± 0.09 for rotation). There was no correlation between intra-rater reliability and clinical experience.Conclusion Visual estimation had excellent intra-rater reliability in the assessment of neck active rotation and head tilt on infants with congenital muscular torticollis. Visual estimation had acceptable inter-rater reliability in the assessment of neck active rotation but not of head tilt. There was a wide variation in reliability with no correlation between reliability and clinical experience. Assessment tools for head tilt that are more psychometrically robust should be developed. What is Known: • A thorough assessment of infants presenting with torticollis is essential, using assessment tools with robust psychometric properties • Visual estimation is the most commonly used method of assessment of neck function in infants with torticollis What is New: • Visual estimation had excellent intra-rater reliability in the assessment of neck active rotation and head tilt in the upright position in videos of infants and acceptable inter-rater reliability in the assessment of rotation but not of head tilt • Physiotherapists' clinical experience had minimal relationship with reliability.

Correlations between the Clinical and Ultrasonographic Parameters of Congenital Muscular Torticollis without a Sternocleidomastoid Mass

Objective

To determine whether ultrasonography at initial presentation can help assess the clinical severity of congenital muscular torticollis (CMT) in infants without a sternocleidomastoid muscle (SCM) mass.

Materials and Methods

This retrospective study included 71 infants aged less than 12 months (4.1 ± 2.3 months) with non-mass CMT. The clinical severity was divided into three grades (groups 1–3) based on the degree of lateral head bending or cervical rotation. The difference (SCM-D) and ratio (SCM-R) between the maximal thickness of the affected and non-affected SCMs were obtained using transverse and longitudinal ultrasonography. The sonographic echotexture and echogenicity of the involved SCM were reviewed.

Results

A significant difference was observed in the SCM-D (0.42 ± 0.30 mm in group 1; 0.74 ± 0.50 mm in group 2; 1.14 ± 0.85 mm in group 3; p = 0.002) and SCM-R (1.069 ± 0.067 in group 1; 1.129 ± 0.087 in group 2; 1.204 ± 0.150 in group 3; p = 0.001) among the groups when measured along the longitudinal but not along the transverse ultrasonography plane. The areas under the curves of the SCM-R and SCM-D measured by longitudinal ultrasonography were 0.731 (p < 0.001) and 0.731 (p < 0.001) for group 1 versus groups 2–3. The proportions of heterogeneous echotexture or hyperechogenicity in the involved SCM did not differ significantly among the three clinical groups (all p > 0.05).

Conclusion

Ultrasonography can aid in assessing the clinical severity of CMT in infants without an SCM mass at the time of initial diagnosis. The SCM-R and SCM-D helped grade the clinical severity when obtained by longitudinal scan.

Motor Function in School-Aged Children With Positional Plagiocephaly or Brachycephaly

OBJECTIVE

To determine whether children with a history of positional plagiocephaly/brachycephaly (PPB) show persistent deficits in motor development.

METHODS

In a longitudinal cohort study, we completed follow-up assessments with 187 school-aged children with PPB and 149 participants without PPB who were originally enrolled in infancy. Primary outcomes were the Bruininks-Oseretsky Test of Motor Proficiency-Second Edition (BOT-2) composite scores.

RESULTS

Children with PPB scored lower than controls on the BOT-2. Stratified analyses indicated that differences were restricted to children who had moderate-severe PPB. No consistent differences were observed in children who had mild PPB.

CONCLUSION

Children who had moderate-severe PPB in infancy show persistent differences in motor function. We suggest close developmental monitoring and early intervention to address motor deficits.

Measurement properties of instruments for assessment of cervical spine function in infants with torticollis: a systematic review

The aim of this study was to systematically review the measurement properties of instruments which assess cervical spine function in infants with torticollis. Electronic searches were performed in MEDLINE, CINAHL, Embase, Web of Science and the Cochrane Library, combining three constructs ('torticollis', 'cervical spine assessment' and 'measurement properties'). Two reviewers independently rated the methodological quality and the quality of measurement properties of identified articles, using both the COSMIN (COnsensus-based Standards for the selection of health status Measurement INstruments) checklist and quality criteria for measurement properties. Five studies, using six instruments, met the inclusion criteria and were analysed. Included instruments were the goniometer, electronic pendular goniometer, protractor, still photography, Muscle Function Scale and a range of motion limitation scale. All studies assessed reliability, and one study also assessed content validity and hypothesis testing. The methodological quality of the studies varied from poor to excellent according to the COSMIN checklist. Two instruments were found to have good measurement properties from high-quality studies: still photography for the assessment of habitual head tilt in supine and the Muscle Function Scale for the assessment of side-flexor muscle function in lateral head righting.Conclusion: This systematic review identified two reliable tools for the assessment of cervical spine function in infants with torticollis. Further research is required to assess the measurement properties of tools already described in the literature and to develop further tools for use in this population. What is known? • A thorough assessment of the infant presenting with torticollis is essential, in order to correctly diagnose, rule out 'red flags' and manage appropriately • Assessment tools need to have robust measurement properties in order to be of value for clinical practice and research What is new? • This systematic review identified two valid and reliable tools for the assessment of cervical spine function in infants with torticollis • Further research is required to assess the measurement properties of tools already described in the literature and to develop further tools for use in infants with torticollis.

A randomized controlled study on the efficiency of soft tissue mobilization in babies with congenital muscular torticollis

BACKROUND

Soft tissue mobilization techniques (STM) are used in clinical practice in treatment of congenital muscular torticollis(CMT).However, little is known about its effectiveness.

OBJECTIVES

To investigate whether using STM to manage CMT in babies with mild to moderate head tilt was effective or not.

METHODS

Twenty-nine babies with CMT aged between 0-6 months, who had a head tilt from 5 to 20 degrees were allocated to two groups. Both groups received a baseline home program (positioning, handling strategies, stretching and strengthening exercises, environmental adaptations). The study group (SG) also received STM three times a week. Babies were evaluated initially, at six weeks, at 12 weeks and for follow-up at 18 weeks with muscle function scale, head tilt and range of motion for neck lateral flexion and rotation.

RESULTS

Both groups showed significant improvements in all measured parameters (p< 0.05). In comparison of groups, there were differences at six weeks in favor of the SG for neck rotation (0.001) and head tilt (= 0.006); but at 12 weeks and follow up, there were no longer any differences between the groups in any of the measured parameters.

CONCLUSIONS

STM techniques are effective in getting faster positive results in the treatment of CMT.

Common Manual Therapy Practices in the Netherlands for Infants With Upper Cervical Dysfunction: A Prospective Cohort Study

OBJECTIVE

The purpose of this study was to describe common clinical practices of manual therapists (MTs) in the Netherlands for infants with indications of upper cervical dysfunction (UCD).

METHODS

A prospective observational cohort study was conducted to gain insight into characteristics, reasons for seeking care, and common clinical practice for infants (<27 weeks) with indications of UCD, referred to MTs. Pre- and posttreatment self-reported questionnaires were used to collect data from parents and MTs. Parents reported on infant characteristics and perceived effect of treatment. Manual therapists reported on diagnostics, therapeutic procedures, and outcomes.

RESULTS

Between 2006 and 2007, data regarding 307 referred infants (mean age: 11.2 weeks) were collected by parents and 42 MTs. The most frequent reasons for seeking care were positional preference, restlessness, and/or abnormal head position. Manual therapists observed active, spontaneous, and provoked mobility and passive upper cervical mobility. Of the 307 infants, 295 were diagnosed with UCD based on positive outcomes on the flexion-rotation test and/or lateral flexion test. After treatment with mobilization techniques, positive outcomes on the flexion-rotation test decreased from 78.8% to 6.8%. For the lateral flexion test, the positive outcomes decreased from 91.5% to 6.2%. All parents perceived positive treatment effects. No serious adverse events were reported during this study.

CONCLUSIONS

This is the first study to describe common clinical practice for infants referred for manual therapy. Infants with UCD were treated mainly with upper cervical mobilization techniques, and the greatest perceived effect was observed after approximately 2 treatment sessions.

Surgical management of congenital torticollis in children older than 7 years with an average 10-year follow-up

The aim of the present study is to present the results of the surgical management of late presenting cases of congenital muscular torticollis. Between 1990 and 2010, 31 cases of late presenting congenital muscular torticollis were managed surgically in our department. Postoperatively, head halter traction was applied for 10 days; a cervical brace was applied for 5 weeks, followed by a soft one collar for 3 months. The final result was assessed on the basis of the criteria of Cheng and Tang. In total, 84% of patients achieved an excellent final result and 16% of the patients achieved a good result. Our results indicated that in children older than 7 years, surgical release combined with appropriate orthosis and a structured physiotherapy regime can lead to satisfactory results.

Positional plagiocephaly is associated with sternocleidomastoid muscle activation in healthy term infants

PURPOSE

To explore the relationship between sternocleidomastoid activation and positional plagiocephaly in healthy full term infants.

METHODS

Participants were 82 infants from a regionally based-longitudinal study of infant development. Sternocleidomastoid (SCM) activation was assessed using active head-righting responses of body-on-head with and against gravity and head-on-body against gravity at 3, 6 and 9 weeks. Plagiocephaly was assessed using the Modified Cranial Vault Asymmetry Index (mCVAI) at 9 weeks.

RESULTS

More severe plagiocephaly was associated with more severe asymmetry in active head-righting responses at all ages (p < 0.001). Greater right-sided occipital flatness was related to stronger contralateral/left SCM activation at 3 and at 9 weeks (p = 0.008). Greater left-sided occipital flatness was related to stronger contralateral/right SCM activation at 3 weeks (p = 0.004). In infants with any right-sided occipital flatness, the mCVAI was greater in infants with asymmetrical gravity assisted body-on-head responses at 3 weeks (mCVAI = 4.31 (2.01)%, 95% CI 2.87-5.75) compared to those with symmetrical responses (mCVAI = 2.64 (1.66)%, 95% CI 2.06-3.22) (p = 0.011).

CONCLUSIONS

Sternocleidomastoid activation asymmetry is a significant contributor to plagiocephaly development by 9 weeks of age due to stronger contralateral SCM activation. Active head-righting responses are appropriate to assess sternocleidomastoid activation in infants under 2 months of age.

Assessing the Cervical Range of Motion in Infants With Positional Plagiocephaly

PURPOSE

To determine if infants with positional plagiocephaly have limitations of active and passive cervical range of motion measured with simple and reliable methods.

METHODS

The examiners assessed bilateral active and passive cervical rotations and passive cervical lateral flexion. Cervical assessment was performed twice by 2 different physicians to assess intertester reliability. To assess intratester reliability the first investigator performed a second examination 48 hours after the first one.

RESULTS

One-hundred nine subjects were analyzed; 70.7% of the sample had head positional preference on the right, while 29.3% had head positional preference on the left (χ 35.52, P <0.001). Cervical rotations and lateral flexion showed reliable levels of agreement for intra and intertester reliability.

CONCLUSIONS

The most limited range of motion in infants with positional plagiocephaly was cervical active rotation which affected more than 90% of patients. Passive cervical rotations and lateral flexion were limited in more than 60% of patients.

Clinical assessment of head orientation profile development and its relationship with positional plagiocephaly in healthy term infants - A prospective study

BACKGROUND

Positional plagiocephaly refers to atypical development of an uneven head shape with asymmetrical head orientation as a post-natal risk factor. The development of the head orientation profile and its relationship with positional plagiocephaly are lacking.

OBJECTIVES

To explore the head orientation profile development and its relationship with positional plagiocephaly in healthy full term infants.

METHODS

A prospective observational study including 94 infants was conducted. Head orientation measures including head orientation duration, head orientation strength and latency to turn were conducted at three, six and nine weeks of age. Plagiocephaly outcome was measured by modified Cranial Vault Asymmetry Index at nine weeks.

RESULTS

Lateral head orientation duration predominated at three weeks, mean (standard deviation) (right=40 [21.7]%; left=41 [21.5]%; midline=19 [19.9]%). It decreased bilaterally in favour of midline positioning at nine weeks (right=30 [22.3]%; left=24 [22.0]%; midline=46 [27]%. Although head orientation strength was similar across the three ages after accounting for side, head orientation strength to left was decreased from three to nine weeks (p=0.031; 95% CI: 0.12-2.06). There was a reduction in left-consistent with increase in left-bias from 3weeks to 6weeks of age (p=0.011). Positional plagiocephaly at nine weeks was associated with head orientation duration-right (p<0.001; r(2)=0.20); head orientation duration-left (p<0.001; r(2)=0.17); head orientation strength at three and six weeks (p<0.001; r(2)=0.22), but not latency to turn.

CONCLUSIONS

Healthy infants show progressive change from symmetrical lateral head orientation to midline orientation from three to nine weeks. There is association of head orientation duration and strength with positional plagiocephaly.

Methods to Diagnose, Classify, and Monitor Infantile Deformational Plagiocephaly and Brachycephaly: A Narrative Review

OBJECTIVE

The purpose of this study is to review the literature for possible methods in diagnosing, classifying, and monitoring deformational plagiocephaly and brachycephaly.

METHODS

A search was conducted on articles through February 2014 in PubMed (Medline) and Google Scholar. Articles were included if they met the following criteria: (1) they were written in English or German; (2) they involved humans; (3) they were published in the last 10 years; (4) they had a primary research question about all possible methods for diagnosing, classifying, and monitoring deformational plagiocephaly and brachycephaly; and (5) an abstract was available.

RESULTS

The search resulted in 58 articles. After the review, the number was reduced to 16. Of the 16 articles included, 9 were reliability studies on measurements of deformational plagiocephaly. Six measurement tools for diagnosing, classifying, and monitoring deformational plagiocephaly and brachycephaly were found: visual assessment, anthropometric measurements with a caliper, measurements with a flexicurve, plagiocephalometry, 3-dimensional photography, and radiological imaging.

CONCLUSION

This study found that visual assessment, flexicurve, anthropometric measurements with a caliper, and plagiocephalometry are useful measurements. At present, the plagiocephalometry and the anthropometric measurements with a caliper are more reliable methods than the visual assessment and the measurement with a flexicurve.

Preventing deformational plagiocephaly through parent guidance: a randomized, controlled trial

Deformational plagiocephaly (DP) occurs frequently in otherwise healthy infants. Many infants with DP undergo physiotherapy or helmet therapy, and ample treatment-related research is available. However, the possibility of preventing DP has been left with little attention. We sought to evaluate the effectiveness of intervention in the newborn's environment, positioning, and handling on the prevalence of DP at 3 months and to investigate the causal relationship between DP and cervical imbalance. We carried out a randomized controlled trial, with healthy newborns randomized into two groups at birth. All families received standard positioning instructions to prevent SIDS. Additionally, the intervention group received detailed instructions regarding the infant's environment, positioning, and handling, with the goal of creating a nonrestrictive environment that promotes spontaneous physical movement and symmetrical motor development. Two- and three-dimensional photogrammetry served to assess cranial shape and goniometry to measure cervical motion. At 3 months, the prevalence of DP was lower in the intervention group in both 2D (11 vs 31 %) and 3D analyses (15 vs 33 %), and the asymmetry was milder in the intervention group. Infants with DP at follow-up had also developed more torticollis.

CONCLUSION

An early educational intervention reduces the prevalence and severity of DP at 3 months.

WHAT IS KNOWN

•Deformational plagiocephaly, often with associated torticollis, is common in healthy infants. •Parental education is frequently recommended for preventing deformational plagiocephaly, although information regarding the effectiveness of preventive strategies is scarce.

WHAT IS NEW

•Early parent guidance effectively reduces the prevalence and severity of DP and improves the cervical range of motion at three months. •Educating both parents and professionals about proper infant positioning on a national scale could help minimize public healthcare costs.

Effectiveness of conservative therapy and helmet therapy for positional cranial deformation

BACKGROUND

The authors investigated the effectiveness of conservative (repositioning therapy with or without physical therapy) and helmet therapy, and identified factors associated with treatment failure.

METHODS

A total of 4378 patients evaluated for deformational plagiocephaly and/or deformational brachycephaly were assigned to conservative (repositioning therapy, n = 383; repositioning therapy plus physical therapy, n = 2998) or helmet therapy (n = 997). Patients were followed until complete correction (diagonal difference <5 mm and/or cranial ratio <0.85) or 18 months. Rates of correction were calculated, and independent risk factors for failure were identified by multivariate analysis.

RESULTS

Complete correction was achieved in 77.1 percent of conservative treatment patients; 15.8 percent required transition to helmet therapy (n = 534), and 7.1 percent ultimately had incomplete correction. Risk factors for failure included poor compliance (relative risk, 2.40; p = 0.009), advanced age (relative risk, 1.20 to 2.08; p = 0.008), prolonged torticollis (relative risk, 1.12 to 1.74; p = 0.002), developmental delay (relative risk, 1.44; p = 0.042), and severity of the initial cranial ratio (relative risk, 1.41 to 1.64; p = 0.044) and diagonal difference (relative risk, 1.31 to 1.48; p = 0.027). Complete correction was achieved in 94.4 percent of patients treated with helmet therapy as first-line therapy and in 96.1 percent of infants who received helmets after failed conservative therapy (p = 0.375). Risk factors for helmet failure included poor compliance (relative risk, 2.42; p = 0.025) and advanced age (relative risk, 1.13 to 3.08; p = 0.011).

CONCLUSIONS

Conservative therapy and helmet therapy are effective for positional cranial deformation. Treatment may be guided by patient-specific risk factors. In most infants, delaying helmet therapy for a trial of conservative treatment does not preclude complete correction.

Impact of torticollis associated with plagiocephaly on infants' motor development

OBJECTIVE

This study investigated whether torticollis (congenital or acquired) in infants with plagiocephaly affects the achievement of specific gross motor milestones.

METHODS

A total of 175 infants affected by plagiocephaly with or without torticollis were recruited and included in this prospective trial. Anthropometric and clinical variables were recorded at baseline. The infants were included in a physiotherapy treatment program, and they were monthly assessed until hospital discharge.

RESULTS

Significant differences (P < 0.05) were observed in the achievement of rolling over, crawling, and standing skills depending on the specific profile (plagiocephaly and plagiocephaly with congenital or acquired torticollis). After adjusting for the severity of the plagiocephaly and the age at referral, the torticollis was significantly (P < 0.05) associated with crawling and standing skills.

CONCLUSIONS

The findings suggest that the presence or absence of congenital or acquired torticollis is an important factor that affects gross motor development in infants with plagiocephaly.

Risk factors for positional plagiocephaly and appropriate time frames for prevention messaging

OBJECTIVE

To determine potential risk factors for developing positional plagiocephaly in infants seven to 12 weeks of age in Calgary, Alberta.

METHODS

A prospective cohort design was used. Healthy term infants (n=440), seven to 12 weeks of age, from well-child clinics at four community health centres in Calgary, Alberta were assessed by the primary author and a registered nurse research assistant using Argenta's plagiocephaly assessment tool. Parents completed a questionnaire surveying risk factors.

RESULTS

The incidence of positional plagiocephaly was estimated to be 46.6%. The following risk factors were identified using multiple logistic regression: right-sided head positional preference (OR 4.66 [95% CI 2.85 to 7.58]; P<0.001), left-sided head positional preference (OR 4.21 [95% CI 2.45 to 7.25]; P<0.001), supine sleep position (OR 2.67 [95% CI 1.58 to 4.51]; P<0.001), vacuum/forceps assisted delivery (OR 1.88 [95% CI 1.02 to 3.49]; P=0.04) and male sex (OR 1.55 [95% CI 1.00 to 2.38]; P=0.05).

CONCLUSION

Advice to vary infants' head positions needs to be communicated to parents/guardians well before the two-month well-child clinic visit. This could occur in the prenatal period by prenatal care providers or educators, or during the neonatal period by postpartum and public health nurses. Prevention education may be emphasized for parents/guardians of male infants and infants who have had assisted deliveries.

Cranial shape, size and cervical motion in normal newborns

BACKGROUND

Deformational plagiocephaly (DP) and torticollis are commonly seen in infants and they often co-occur, but little is known of the prevalence and relationship of these conditions in the immediate newborn period. No previous studies focusing on the relationship between cranial shape and cervical motion in newborns can be found.

OBJECTIVES

Determining the incidence rates and characteristics of DP and torticollis and examining the relationship between cervical range of motion (ROM), cranial size and cranial shape in neonates.

METHODS

A single-center, descriptive cross-sectional study including 155 healthy neonates was conducted. Participants were examined during their birth hospitalization. Oblique Cranial Length Ratio (OCLR) and Cephalic Index (CI), indicating cranial asymmetry and shape, were measured from standardized digital photographs with a computer-based cephalometric method. Cervical ROM was measured with goniometry.

RESULTS

7.7% of the newborns had DP and 3.9% had torticollis. 46.4% presented lesser cervical imbalances. DP was associated with gestational diabetes (adjusted OR 5.6; p<0.01) and vacuum assisted delivery (adjusted OR 6.8; p<0.01), but not at all with torticollis. CI correlated strongly with cervical ROM in all directions, while no definite association between cranial asymmetry and cervical motion could be found.

CONCLUSIONS

DP and torticollis are common and minor cervical imbalances very common in normal newborns. Our results support the theory that in most cases neither DP nor torticollis is congenital, but rather develops and worsens synergistically in early infancy. Still, although no direct association between DP and torticollis was found, cranial shape is linked to cervical motion at birth.

Positional plagiocephaly: an analysis of the literature on the effectiveness of current guidelines

OBJECT

Positional plagiocephaly (PP) has been on the rise in recent years. In this review, the authors' aim was to assess the effectiveness of current recommendations to parents on this exceedingly common problem through a comprehensive literature search. Additionally, the current treatment options and the most recent studies on PP are reviewed.

METHODS

A search of the existing literature was conducted to obtain all relevant studies on guidelines, recommendations, parental and clinician practices, and epidemiological aspects.

RESULTS

Although the incidence and risk factors for PP have been well delineated, there continues to be debates on its management and association with developmental delays. Current guidelines and recommendations on prevention set by the American Association of Pediatrics may not be easily followed by both parents and clinicians. There is also evidence that certain populations, including those with lower education, socioeconomic status, and in particular geographic regions may be more affected by the condition. Additionally, the marketing and financial aspects of PP treatments exist and should be addressed.

CONCLUSIONS

Better awareness and education are necessary to inform the population as a whole, although certain populations should be given special attention. Additionally, current guidelines and recommendations can be modified to foster a better grasp of the condition by both parents and clinicians. Adjusting current recommendations, introducing initiatives, and offering elaborate educational campaigns would help deliver these aims. Educating parents on PP as early as possible through clearer guidelines and close monitoring is central to preventing and managing this common condition.

Is sternocleidomastoid muscle release effective in adults with neglected congenital muscular torticollis?

BACKGROUND

Neglected congenital muscular torticollis is rare in adults but may be associated with pain and cosmetic problems. The efficacy of surgical correction in these patients has not been well established in the literature.

QUESTIONS/PURPOSES

We sought to describe (1) the primary goals that influenced adults with neglected muscular torticollis to seek surgical correction, (2) improvements of patients' function (specifically ROM) and radiographic parameters associated with deformities, (3) patient-derived outcomes using a previously published scale that includes function, and cosmesis, and (4) complications associated with sternocleidomastoid release in one surgeon's series of patients.

METHODS

We retrospectively reviewed the records of all adult patients who had surgical release of the sternocleidomastoid muscle between 2003 and 2011 by one surgeon and who were followed up for more than 1 year after surgery; 42 of these procedures were performed, and complete followup was available for 37 of them (88%). The mean age of the patients was 27 years (range, 18-48 years), and the minimum followup was 1.5 years (mean, 2.4 years; range, 1.5-4.7 years). The primary goal of the operation for each patient was determined to assess if it was met. Functional outcomes were assessed in terms of motion deficit: lateral flexion and rotation. Radiographic outcomes were assessed for cervicomandibular angle, lateral translation of the head and neck, and Cobb's angle of the cervicothoracic spine. The overall clinical results of surgery were assessed with the modified Cheng and Tang scoring system, and complications were tallied from a chart review.

RESULTS

The primary goals of surgery were cosmesis in 17 (46%) patients, pain in 11 (30%) patients, and function in nine (24%) patients. Patients for whom pain was the primary goal of surgery were older than the other patients. ROM and radiographic parameters associated with deformity consistently improved in these patients (p < 0.001 in all planes), and the overall results according to the modified Cheng and Tang scoring system indicated that 21 (57%) patients had an excellent result, 12 (32%) had a good result, and four (11%) had a fair result. There were no serious complications and no reoperations in these patients.

CONCLUSIONS

Sternocleidomastoid release was beneficial for the treatment of neglected congenital muscular torticollis in adults and was not associated with any serious complications. Surgical treatment led to cosmetic and functional improvements and relieved pain originating from the muscle imbalance brought about by the long-standing deformity.

Conservative management of congenital muscular torticollis: an evidence-based algorithm and preliminary treatment parameter recommendations

PURPOSE

To present an algorithm with accompanying treatment parameters for the management of congenital muscular torticollis (CMT) based on the best available literature.

METHODS

A systematic search of PubMed, MEDLINE, CINHAL, and Cochrane databases was conducted to identify evidence to guide the conservative management of CMT.

RESULTS

An evidence-based algorithm was created based on three prognostic factors that influence treatment duration and outcome, including a sternocleidomastoid fibrotic mass, passive range of motion rotation deficit, and age at initiation of treatment. Preliminary treatment parameter recommendations for clinic and home programming accompany the algorithm.

CONCLUSION

Use of the proposed evidence-based algorithm with accompanying preliminary treatment parameter recommendations may improve consistency of care and outcomes for infants with CMT. While a higher level of evidence supports the three prognostic factors utilized in the algorithm, research gaps continue to exist with regards to treatment parameters.

Is craniofacial asymmetry progressive in untreated congenital muscular torticollis?

BACKGROUND

Although craniofacial asymmetry is frequently involved in patients with congenital muscular torticollis, it has not been evaluated appropriately. The authors analyzed preoperative craniofacial asymmetry objectively and confirmed the relationship between craniofacial asymmetry and aging in congenital muscular torticollis patients who underwent surgical release.

METHODS

The authors retrospectively measured preoperative craniofacial asymmetry using the Cranial Vault Asymmetry Index and intercommissural angle and reviewed preoperative rotational and flexional deficit of neck movement for 123 congenital muscular torticollis patients who underwent surgical release at Ajou Medical Center from February of 2007 to February of 2011. The relationships among Cranial Vault Asymmetry Index, intercommissural angle, rotational deficit, flexional deficit, and age were analyzed. Mean values of dependent variables were compared after patients were grouped by age.

RESULTS

Mean age at operation was 82.5 months (range, 5 to 498 months). Seventy-one percent (n=87) of patients had a significant cranial asymmetry and 87 percent (n=107) had a significant facial asymmetry. In correlation analysis, intercommissural angle increased proportional to age (r=0.334, p=0.000), especially before 3 years (r=0.42, p=0.001). Cranial Vault Asymmetry Index was unrelated to age or rotational or flexional deficit. Rotational deficit decreased proportional to age (r=-0.229, p=0.032). By analysis of variance test, intercommissural angle and rotational deficit between the age groups were statistically significantly different (p<0.05).

CONCLUSIONS

In congenital muscular torticollis, facial asymmetry is progressive if the contracted sternocleidomastoid muscle is not released, although cranial asymmetry is already determined in those younger than 6 months. Early correction of torticollis should be considered to prevent progression of facial asymmetry in congenital muscular torticollis patients.

Clinical profile and evolution of infants with deformational plagiocephaly included in a conservative treatment program

PURPOSE

The aim of this study was to evaluate the results of a conservative intervention in infants with plagiocephaly according to their specific clinical profile.

METHODS

Prospective clinical trial in which 104 infants with plagiocephaly accompanied or not by congenital or positional torticollis were referred to Early Care and Monitoring Unit (USAT) of San Cecilio Hospital in Granada, between 2009 and 2012. All the infants, grouped into three categories of severity, were included in the physiotherapy protocol until adequate craniofacial morphology and motor development were achieved. The study included an assessment of parents and infants. Parents were assessed with a questionnaire about the mother's medical history and birth-related issues. The assessment of infants included anthropometric measures, a positional assessment, the observation of the head, the assessment of severity, and motor development.

RESULTS

Birth characteristics were similar in the total sample but showed different clinical profiles according to treatment aspects. More specifically, infants with severe plagiocephaly were referred to treatment later and spent more time in treatment; use of an orthotic helmet was also more prevalent in this category. There were also significant differences (P < 0.05) in the acquisition of specific gross motor skills depending on the severity of plagiocephaly.

CONCLUSION

The findings suggest that the physiotherapy protocol presented is effective to correct plagiocephaly. Severity of plagiocephaly is a marker that should be taken into account when designing actions aimed at improving gross motor skill development.

The value of high-frequency and color Doppler ultrasonography in diagnosing congenital muscular torticollis

Background

Congenital muscular torticollis (CMT) is a relatively common neck deformity in infancy. The aim of our research was to determine the value of high-frequency and color Doppler ultrasonography in diagnosing CMT.

Methods

Patients with a clinical suspicion of CMT underwent an ultrasound examination before diagnosis, and the sonographic characteristics were analyzed and compared with the clinical findings.

Results

The sensitivity and specificity of an ultrasound diagnosis for CMT was 95.83% and 83.33%, respectively. The patients were divided into 2 groups based on the stage of the disease: the early-stage group (age <1 year) and the late-stage group(age ≥1 year). Differences existed between the two groups with respect to sonographic findings and clinical characteristics. The sonographic characteristics of the early-stage group included local thickening of the sternocleidomastoid muscle (SCM), weak or uneven echoes, and blood flow signals around or inside most of the lesions. The sonographic characteristics of the late-stage group included diffusely hyperechoic, or cord-like hyperechoic signals inside the muscle layer without significant blood flow signals.

Conclusions

Different stage of CMT patients had different sonographic characteristics. High-frequency and color Doppler ultrasonography can serve as adjunct confirmation tool for the diagnosis of CMT.

Deformational plagiocephaly and orthotic treatment: indications and limitations

PURPOSE

As the incidence of deformational plagiocephaly (DP) has risen, so has the demand on clinicians to make appropriate treatment recommendations. While knowledge of risk factors and natural history continue to evolve, there is uncertainty and controversy regarding intervention approaches. The purpose of this report is to review current treatment approaches for DP, in particular the use of orthotic helmets.

METHODS

A narrative literature review was conducted to summarize current evidence supporting preventative measures and re-positional and orthotic interventions.

RESULTS

When started early at under 2 months of age, positional efforts and 'tummy time' can be effective in preventing and improving DP, but these strategies need to be better promoted to caregivers. The timing, severity and parental concerns as indicators for orthotic treatment are reviewed. Limitations discussed include high cost, lower level of evidence and poor understanding of long-term outcomes and caregiving implications.

CONCLUSION

For optimal outcome, current evidence supports use of repositioning in young infants and start of orthotic helmet treatment for infants with significant DP at 4-6 months. Further research is needed to better understand the parameters for use (stratified by age and severity), long-term outcomes and natural history and the impact on caregiving, as well as the cultural significance of head shape.

Evidence-based care of the child with deformational plagiocephaly, Part I: assessment and diagnosis

Non-synostotic deformational plagiocephaly (DP) is head asymmetry that results from external forces that mold the skull in the first year of life. Primary care providers are most likely to encounter DP when infants present for well-child care, and for this reason it is important that providers be competent in assessing, diagnosing, and participating in the prevention and management of DP. The purpose of this two-part series on DP is to present an overview of assessment, diagnosis, and evidence-based management of DP for health care providers. In Part I we provide a brief background of DP and associated problems with torticollis and infant development, and we present strategies for visual and anthropometric assessment of the infant with suspected DP. We also provide tools for differentiating DP from craniosynostosis and for classifying the type and severity of lateral and posterior DP. Part II (to be published in a future issue of the Journal of Pediatric Health Care) provides a synthesis of current evidence and a clinical decision tool for evidence-based management of DP.

Positional plagiocephaly: what the pediatrician needs to know. A review

INTRODUCTION

Positional or deformational plagiocephaly is the most common type of cranial asymmetry in infancy and has become more prevalent after the introduction of the "Back to Sleep" campaign in Western countries. However, the supine position cannot be considered as the only etiologic factor and different predisposing variables have been investigated in the last few years.

DISCUSSION

The pediatrician should correctly diagnose this condition and exclude the possibility of craniosynostosis in any child with plagiocephaly in order to optimize management and reduce potential morbidity associated with different conditions other than positional ones. In addition, the pediatrician needs to be able to educate parents on methods to proactively decrease the likelihood of the development of occipital flattening, initiate appropriate management, and make referrals when necessary.

Clinical features and outcome of physiotherapy in early presenting congenital muscular torticollis with severe fibrosis on ultrasonography: a prospective study

BACKGROUND

It has been reported that ultrasonography (US) can detect the severity of congenital muscular torticollis (CMT), and severe fibrosis of the sternocleidomastoid (SCM) muscle noted on US is irreversible and likely to require surgery. Clinical outcome of CMT depends mainly on the patient's age, which is also associated with the severity of fibrosis as determined by US. However, there has been no well-designed study to elucidate the true relationship among these factors nor a definite consensus on treatment of young infants with severe fibrosis in the SCM compared with well-documented reports that late cases require surgery.

PURPOSE

The purpose of the current study was to investigate whether severity of SCM fibrosis on US is correlated with clinical severity and outcome of standardized physiotherapy in early presenting CMT.

METHODS

Fifty patients with a palpable neck mass, initial deficit of passive neck rotation (ΔROT) more than 10°, and age less than 3 months were classified into 4 US types according to the severity of fibrosis in the SCM and underwent standardized physiotherapy and regular assessment. Relationship between US types and 2 variables (ΔROT and treatment duration) and success rate of physiotherapy was assessed.

RESULTS

None of the cases was classified as type 4. Type 3 showed greatest ΔROT and longest mean treatment duration. Both variables showed a significant linear trend of association with US types by P for trend (P = .003, P < .001, respectively). Treatment was "successful" in 49 patients (98%).

CONCLUSION

In young infants with CMT, US can document severity; and an early and adequate physiotherapy is a good treatment option, particularly even in those with severe fibrosis.

Deformational plagiocephaly, brachycephaly, and scaphocephaly. Part I: terminology, diagnosis, and etiopathogenesis

Cranial deformation is the most common cause of abnormal head shape. Intentional and unintentional alterations of cranial form are associated with the application of external pressure to the growing infant head, and such changes have been recorded throughout man's history. Recent changes in Western sleeping practices, instituted to reduce the incidence of sudden infant death syndrome, have led to a dramatic rise in the incidence of cranial deformation and renewed interest in this subject. This 2-part review presents a pragmatic clinical approach to this topic including a critical review of the literature as it applies to each aspect of this common diagnosis: historical perspective, terminology, differential diagnosis, etiopathogenesis and predisposing factors, and prevention and treatment.
