Efficacy of pediatric integrative manual therapy in positional plagiocephaly: a randomized controlled trial.
Featured on Physle Daily · Thursday, 15 October 2026
Positional plagiocephaly, the flattening of a baby's head shape that can develop from consistent lying positions, is usually managed with repositioning advice and stimulation exercises. This trial asked whether adding hands-on pediatric manual therapy to a caregiver education program would improve head shape more than education alone in infants under 28 weeks old with asymmetric skulls. Over 10 weeks, infants receiving manual therapy alongside education showed a larger reduction in cranial vault asymmetry, a measurement of skull asymmetry, than those receiving education only, and parents in that group also reported feeling more positively about the changes they saw. A separate measure of overall head shape, cranial index, did not show a significant difference between groups.
Because the comparison group received less hands-on attention, part of the parental perception difference could reflect attention or expectation rather than the manual therapy itself. The trial was small, with 34 infants, which limits how confidently these results can be generalized.
If your baby has been diagnosed with positional plagiocephaly, a flattened or asymmetric area of the skull often linked to sleeping position, you may wonder whether hands-on therapy adds anything beyond the usual advice about repositioning and encouraging movement. This small study of 34 babies under 28 weeks old compared adding manual therapy sessions to a caregiver education program against giving the education program alone. Babies who received manual therapy showed a bigger improvement in one measure of skull asymmetry, and their parents also felt more positively about the changes compared to parents in the education-only group.
However, another measure of overall head shape did not show a clear difference between the two groups, so the benefit was not uniform across all the ways head shape was measured. Because the manual therapy group also received more hands-on attention, it is possible some of the parental satisfaction reflects that extra contact rather than the therapy itself.
With only 34 infants studied, these findings should be seen as preliminary rather than conclusive.
This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.
This trial addresses whether adding pediatric integrative manual therapy to a standard caregiver education program (repositioning plus sensory-motor stimulation) improves outcomes in positional plagiocephaly beyond education alone, a question relevant when counseling families about conservative management options before considering helmet therapy. In this randomized controlled trial of 34 neurologically healthy infants under 28 weeks with at least 5mm diagonal diameter difference, the manual therapy group showed a significantly greater reduction in cranial vault asymmetry index (3.72% ± 1.40% vs 0.34% ± 1.72%, p=0.000) and more positive parental perception scores (6.66 vs 4.25 cm on a visual analogue scale, p=0.004) than the education-only group over 10 weeks. Cranial index showed no significant between-group difference, indicating the manual therapy's benefit was specific to the asymmetry measure rather than uniform across head shape parameters.
Because the control group received comparatively less therapist contact and no sham intervention was used, the parental perception finding in particular may partly reflect attention or expectation effects rather than a specific treatment mechanism. The abstract does not report adverse events, and the trial was retrospectively registered, both factors that temper confidence. With a single small trial, these results inform rather than establish manual therapy's role, and the sample size and lack of long-term follow-up limit generalizability to broader practice.
In a small trial of 34 infants with positional plagiocephaly, adding pediatric manual therapy to a caregiver education program produced a greater decrease in cranial vault asymmetry index than education alone (3.72% vs 0.34%, a statistically significant difference).
Cranial index, a separate measure of head shape, did not differ significantly between groups, so the benefit was not consistent across all shape measures.
Parents in the manual therapy group rated perceived improvement more positively on a visual analogue scale than parents in the education-only group, a statistically significant difference.
