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.

Assessing calvarial vault constriction associated with helmet therapy in deformational plagiocephaly.

OBJECTIVE Deformational plagiocephaly and/or brachycephaly (DPB) is a cranial flattening frequently treated in pediatric craniofacial centers. The standard of care for DPB involves patient positioning or helmet therapy. Orthotic therapy successfully reduces cranial asymmetry, but there is concern over whether the orthotics have the potential to restrict cranial growth. Previous research addressing helmet safety was limited by lack of volume measurements and serial data. The purpose of this study was to directly compare head growth data in patients with DPB between those who underwent helmet therapy and those who received repositioning therapy. METHODS This retrospective cohort study analyzed pre- and posttherapy 3D photographs of 57 patients with DPB who had helmet therapy and a control group of 57 patients with DPB who underwent repositioning therapy. The authors determined the change in cranial vault volume and cranial circumference between each patient's photographs using 3D photogrammetry. They also computed a cubic volume calculated by multiplying anterior-posterior diameter, biparietal diameter, and height. Linear regressions were used to quantify effects of age and therapy type on these quantities. RESULTS A comparison of the following variables between the two groups yielded nonsignificant results: age at the beginning (p = 0.861) and end (p = 0.539) of therapy, therapy duration (p = 0.161), and the ratio of males to females (p = 0.689). There was no significant difference between patients who underwent helmeting versus positioning therapy with respect to change in either volume calculation or head circumference z-score (p ≥ 0.545). Pretherapy photograph age was a significant predictor of cranial growth (p ≤ 0.001), but therapy type was not predictive of the change in the study measurements (p ≤ 0.210). CONCLUSIONS The authors found no evidence that helmet therapy was associated with cranial constriction in the study population of patients with DPB. These results strengthen previous research supporting helmet safety and should allow health care providers and families to choose the appropriate therapy without concern for potential negative effects on cranial growth.

Long-term outcomes in treatment of deformational plagiocephaly and brachycephaly using helmet therapy and repositioning: a longitudinal cohort study.

OBJECTIVES: Deformational plagiocephaly and/or brachycephaly (DPB) is a misshapen head presenting at birth or shortly thereafter, caused by extrinsic forces on an infant's malleable cranium. There are two treatment methods available for DPB: helmeting and repositioning. Little is known about the long-term outcomes of these two treatment options. The purpose of this study was to examine children who received helmeting or repositioning therapy for DPB as infants and compare the long-term head shape outcomes of the two groups. METHODS: A longitudinal cohort study design was used to evaluate change in head shape of the two groups. One hundred children (50 helmeted, 50 repositioned) were initially evaluated at 6 months or younger for DPB. Anthropometric skull measurements taken as infants before treatment were compared with measurements taken for this study. Inclusion criteria included initial clinic visit at age 6 months or younger, evaluation by the same practitioner, and current age 2-10 years. Cephalic index and cranial vault asymmetry were calculated based on caliper measurements. RESULTS: Data from 100 children were evaluated for this study. Significant differences between the treatment groups in the mean change in cephalic index (p = 0.003) and cranial vault asymmetry (p < 0.001) were found; the children that used helmet therapy demonstrated greater improvement. CONCLUSIONS: This is one of the larger published long-term outcome studies comparing children that used helmets and repositioning to treat their DPB as infants. The data suggest that infants will have more improvement in head shape with a helmet than with repositioning.

Prevention of deformational plagiocephaly in hospitalized infants using a new orthotic device.

OBJECTIVE: To measure the feasibility, safety, and efficacy of the cranial cup device in a sample of hospitalized infants at risk for deformational plagiocephaly (DP). DESIGN: A multisite, stratified, and randomized single-blinded study. SETTING: Neonatal intensive care units (NICU) from three urban and one suburban hospital participated. PARTICIPANTS: Subjects included 62 infants with lengths of stay ≥ 14 days. METHODS: Nurses caring for infants in study group 1 used the moldable positioner. In study group 2, nurses rotated the moldable positioner and cranial cup devices using the cranial cup for a target goal of 12 hours/day. Both study groups received routine position changes. Outcome measures included hours of device use (feasibility), cardiorespiratory and emesis events (safety), and cranial measurements obtained at discharge (efficacy) by one of four, licensed orthotists who were blinded to the study. RESULTS: A total of 35 infants were randomized to study group 1 (moldable positioner) and 27 infants to study group 2 (moldable positioner and cranial cup). The median hours per day on the cranial cup was 10.7 (range 4.5-15.3). Emesis and cardiorespiratory events were equally distributed for the moldable positioner and cranial cup devices in study group 2. At discharge, more infants in study group 1 (46%, n = 16) exhibited abnormal cranial measurements than those in study group 2 (19%, n = 5) (p = .03). CONCLUSION: Rotating the cranial cup with the moldable positioner provides a feasible, safe, and potentially efficacious therapy for prevention of DP.

Response to pediatric physical therapy in infants with positional preference and skull deformation.

BACKGROUND: Pediatric physical therapy seems to reduce skull deformation in infants with positional preference. However, not all infants show improvement. OBJECTIVE: The study objective was to determine which infant and parent characteristics were related to responses to pediatric physical therapy in infants who were 2 to 4 months old and had positional preference, skull deformation, or both. DESIGN: This was a prospective cohort study. METHODS: Infants who were 2 to 4 months old and had positional preference, skull deformation, or both were recruited by pediatric physical therapists at the start of pediatric physical therapy. The primary outcome was a good response or a poor response (moderate or severe skull deformation) at 4.5 to 6.5 months of age. Potential predictors for responses to pediatric physical therapy were assessed at baseline with questionnaires, plagiocephalometry, and the Alberta Infant Motor Scale. Univariate and multiple logistic regression analyses with a stepwise backward elimination method were performed. RESULTS: A total of 657 infants participated in the study. At follow-up, 364 infants (55.4%) showed a good response to therapy, and 293 infants (44.6%) showed a poor response. Multiple logistic regression analysis resulted in the identification of several significant predictors for a poor response to pediatric physical therapy at baseline: starting therapy after 3 months of age (adjusted odds ratio [aOR]=1.50, 95% confidence interval [95% CI]=1.04-2.17), skull deformation (plagiocephaly [aOR=2.64, 95% CI=1.67-4.17] or brachycephaly [aOR=3.07, 95% CI=2.09-4.52]), and a low parental satisfaction score (aOR=2.64, 95% CI=1.67-4.17). A low parental satisfaction score indicates low parental satisfaction with the infant's head shape. LIMITATIONS: Information about pediatric physical therapy was collected retrospectively and included general therapy characteristics. Because data were collected retrospectively, no adjustment in therapy for individual participants could be made. CONCLUSIONS: Several predictors for responses to pediatric physical therapy in infants who were 2 to 4 months old and had positional preference, skull deformation, or both were identified. Health care professionals can use these predictors in daily practice to provide infants with more individualized therapy, resulting in a better chance for a good outcome.

Posterior remodeling flap for posterior plagiocephaly.

INTRODUCTION: Nonsynostotic posterior plagiocephaly has become the most common skull deformation since pediatricians have suggested the supine position for the newborns to reduce the risk of sudden death. Prevention of such a "positional" deformation or its management once it has occurred is mainly based on physical maneuvers such as physiotherapy and active positional corrective measures. SELECTION CRITERIA: Surgical correction, however, may be suggested in rare cases where deformation of the skull is so severe or the referral of the child is so late that physical corrective treatment cannot be taken into consideration. Surgical management is based on the creation of a posterior bone flap to be repositioned after the opportune contouring and rotation. PURPOSE: The aim of this paper is to describe the surgical technique used for posterior vault remodeling in posterior plagiocephaly at the craniofacial unit of Hopital Necker Enfants Malades (French National Referral Center for Faciocraniosynostosis) focusing on its advantages and limitations.

Effect of pediatric physical therapy on deformational plagiocephaly in children with positional preference: a randomized controlled trial.

OBJECTIVE: To study the effect of pediatric physical therapy on positional preference and deformational plagiocephaly. DESIGN: Randomized controlled trial. SETTING: Bernhoven Hospital, Veghel, the Netherlands. PARTICIPANTS: Of 380 infants referred to the examiners at age 7 weeks, 68 (17.9%) met criteria for positional preference, and 65 (17.1%) were enrolled and followed up at ages 6 and 12 months. INTERVENTION: Infants with positional preference were randomly assigned to receive either physical therapy (n = 33) or usual care (n = 32). MAIN OUTCOME MEASURES: The primary outcome was severe deformational plagiocephaly assessed by plagiocephalometry. The secondary outcomes were positional preference, motor development, and cervical passive range of motion. RESULTS: Both groups were comparable at baseline. In the intervention group, the risk for severe deformational plagiocephaly was reduced by 46% at age 6 months (relative risk, 0.54; 95% confidence interval, 0.30-0.98) and 57% at age 12 months (0.43; 0.22-0.85). The numbers of infants with positional preference needed to treat were 3.85 and 3.13 at ages 6 and 12 months, respectively. No infant demonstrated positional preference at follow-up. Motor development was not significantly different between the intervention and usual care groups. Cervical passive range of motion was within the normal range at baseline and at follow-up. When infants were aged 6 months, parents in the intervention group demonstrated significantly more symmetry and less left orientation in nursing, positioning, and handling. CONCLUSION: A 4-month standardized pediatric physical therapy program to treat positional preference significantly reduced the prevalence of severe deformational plagiocephaly compared with usual care.

Nonsurgical treatment of deformational plagiocephaly: a systematic review.

OBJECTIVE: To evaluate and summarize the evidence comparing nonsurgical therapies in the treatment of infants with deformational plagiocephaly. DATA SOURCES: Scientific articles and abstracts published in English between January 1978 and August 2007 were searched from 5 online literature databases, along with a manual search of conference proceedings. STUDY SELECTION: Studies were selected and appraised for methodological quality by 2 reviewers independently using a Critical Appraisal Skills Programme form (cohort criteria). INTERVENTIONS: Molding helmet therapy vs head repositioning therapy. MAIN OUTCOME MEASURE: Success rate of the treatment. RESULTS: A total of 3793 references were retrieved. There were no randomized controlled trials. Only 7 cohort studies met the inclusion criteria. Five of the 7 studies presented evidence that molding therapy is more effective than repositioning, even with the biases favoring the repositioning groups. In the molding groups, the asymmetry was more severe and the infants were older. The infants who failed to respond to repositioning therapy were also switched to molding therapy. The treatment outcomes from the other 2 studies were difficult to assess because of flaws in their study design. Finally, the relative improvement of using molding therapy was calculated from one study. It was about 1.3 times greater than with repositioning therapy. CONCLUSION: The studies showed considerable evidence that molding therapy may reduce skull asymmetry more effectively than repositioning therapy. However, definitive conclusions on the relative effectiveness of these treatments were tempered by potential biases in these studies. Further research is warranted.

Torticollis and plagiocephaly in infancy: therapeutic strategies.

BACKGROUND: Asymmetry in infancy is a diagnosis with a large spectrum of features, expressing an abnormal shape of parts of the body or unequal postures and movements, which might be structural and/or functional, with localized or generalized expression. PURPOSE: The purpose of the present study is to highlight different therapeutic aspects of the most occurring asymmetries in infancy: congenital muscular torticollis, positional torticollis and plagiocephaly, based on best evidence in current literature. RESULTS: A flow chart is presented showing different pathways in therapeutic strategies, such as physical therapy, orthotic devices (helmet treatment and Dynamic Orthotic Cranioplasty) and surgery. CONCLUSION: It is concluded that there are different views towards management on torticollis and plagiocephaly. A systematic therapeutic management to evaluate these asymmetries is indicated. The presented therapeutic flow chart might serve as a basis in order to achieve uniformity in therapeutic thinking and performance.
