Manual therapy of infants with postural and movement asymmetries and positional preference

Background There are different therapeutic approaches to persistent positional preference (kinematic imbalance due to suboccipital strain, KISS) in infants. There are no evidence-based or controlled studies investigating the effect of manual medicine treatment in children aged 3–6 months, particularly in combination with a home exercise programme. The presented monocentric study on one-time manual medicine treatment of infants aged 14–24 exhibiting these symptoms aims to close this gap. Methods This study comprises a controlled double-blind trial and per-protocol-analysis. Primary outcome was the 4-item symmetry score (4–17 points). The second measurement was performed after 4–6 weeks. Results A total of 62 infants were treated and evaluated (mean age 17 weeks). The intervention and control groups started with a symmetry score of 12.9 ± 2.1 and 12.5 ± 1.7 points, respectively. In the intervention group the score improved by 4.9 ± 2.4 to 8.0 ± 2.7 points, in the control group it improved by 2.9 ± 2.9 to 9.6 ± 3.0 points. The difference between the groups was statistically significant (p = 0.03). Both groups had significantly better values over time (p < 0.001). No adverse events or side effects were observed. Conclusion Manual medicine treatment of infants with postural and movement asymmetries as well as positional preference in combination with a home exercise programme is superior to a home exercise programme alone. Both treatment concepts achieved significant improvements. However, the manual medicine treatment played an important role in reducing the symmetry score value for the affected children, such they were no longer in need of treatment.

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.
