This review synthesized current research evidence on the prevalence, risk factors, and natural history of positional plagiocephaly. Research published between 1985 and 2007 was sourced from 13 databases. Evidence was categorized according to a hierarchy and rated on a standardized critical appraisal tool. These evaluations were incorporated into a narrative synthesis of the main results. Eighteen studies met inclusion criteria (prevalence: n=3, risk factors: n=17, natural history: n=1). The methodological quality of studies was fair. The point prevalence of positional plagiocephaly appears to be age‐dependent and may be as high as 22.1% at 7 weeks of age. Point prevalence tends to decrease with age and may be as low as 3.3% at 2 years. When compared with historical data, the prevalence of positional plagiocephaly appears to have remained stable over the last four decades. Assisted delivery, first born child, male sex, cumulative exposure to the supine position, and neck problems may increase the risk of positional plagiocephaly. To reduce the risk of positional placiocephaly, infants should experience a variety of positions, other than supine, while they are awake and supervised, and early treatment may be warranted for infants with neck problems and/or strong head preference.

This review aimed to synthesize current research evidence to determine the effectiveness of conservative interventions for infants with positional plagiocephaly. A systematic review was conducted, where papers were sourced from 13 library and internet databases. Research was included if published in English between 1983 and 2003. Level of evidence and quality of each paper was assessed to determine studies’magnitude of inherent bias. Results were synthesized in a narrative format and were considered with respect to homogeneity of participants, response rate, and outcome measures. Sixteen papers met inclusion criteria: 12 were case series and four were comparative studies. The methodological quality of the studies was moderate to poor, thus their results should be interpreted with caution. A consistent finding was that counterpositioning ± physiotherapy or helmet therapy may reduce skull deformity; however, it was not possible to draw conclusions regarding the relative effectiveness of these interventions. Further investigation is required to compare the effect of helmet therapy with counterpositioning alone or when combined with physiotherapy. First, there is a need to develop an outcome measurement battery which incorporates psychometrically‐sound measures from the perspectives of clinicians and patients.

Executive summaryBackground Obstetric brachial plexus palsy, a complication of childbirth, occurs in 1-3 per 1000 live births internationally. Traction and/or compression of the brachial plexus is thought to be the primary mechanism of injury and this may occur in utero , during the descent through the birth canal or during delivery. This results in a spectrum of injuries that vary in severity, extent of damage and functional use of the affected upper limb. Most infants receive treatment, such as conservative management (physiotherapy, occupational therapy) or surgery; however, there is controversy regarding the most appropriate form of management. To date, no synthesised evidence is available regarding the effectiveness of primary conservative management for obstetric brachial plexus palsy.Objectives The objective of this review was to systematically assess the literature and present the best available evidence that investigated the effectiveness of primary conservative management for infants with obstetric brachial plexus palsy. ) were included in this review.Selection criteria Quantitative studies that investigated the effectiveness of primary conservative management for infants with obstetric brachial plexus palsy were eligible for 28 A Bialocerkowski et al. inclusion in this review. This excluded studies that solely investigated the effect of primary surgery for these infants, management of secondary deformities and the investigation of the effects of pharmacological agents, such as botulinum toxin. Data collection and analysisTwo independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion. Studies were assessed for clinical homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format. ResultsEight studies were included in the review. Most were ranked low on the Hierarchy of Evidence (no randomised controlled trials were found), and had only fair methodological quality. Conservative management was variable and could consist of active or passive exercise, splints or traction. All studies lacked a clear description of what constituted conservative management, which would not allow the treatment to be replicated in the clinical setting. A variety of outcome instruments were used, none of which had evidence of validity, reliability or sensitivity to detect change. Furthermore, less severely affected infants were selected to receive conservative management. Therefore, it is difficult to draw conclusions regarding the effectiveness of conservative management for infants with obstetric brachial plexus palsy. ConclusionsThere is scant, inconclusive evidence regarding the effectiveness of primary conservative intervention for infants with obstetric brachial plexus palsy. Further research should be directed to develop outcome instruments with sound psychometric properties for i...
