“…Four infants died after recruitment leaving 109 children eligible for follow‐up. The current study cohort consisted of the 99 children who had repeated assessments with the SOMP‐I during the first year 7 and were assessed with the Bayley‐III at 2.5 years' corrected age (median: 31 months range 27‐44 months). One child was excluded due to a condition unrelated to the prematurity [Corrections made on 11 September 2020, after first online publication: In the preceding sentence, “congenital orthopaedic disorder” has been changed to “condition unrelated to the prematurity” in this version.].…”

“…Both the infant's level of motor development and quality of motor performance are assessed. 7 The method also allows for repeated assessments to monitor the infant's development. The main purpose of the SOMP-I is to identify infants in need of early motor interventions, regardless of the underlying cause.…”

The aim of this study was to investigate the level of motor development and the quality of motor performance during the first 10 months in relation to the Bayley Scales of Infant Development-third edition (Bayley-III) motor index at 2.5 years. Methods: Children born very preterm from a population-based study (n = 113) were assessed with the Structured Observation of Motor Performance in Infants (SOMP-I) at 2, 4, 6 and 10 months corrected age and the Bayley-III motor index at 2.5 years corrected age (n = 98). Logistic regressions were performed to investigate the independent association of each SOMP-I domain to Bayley-III motor index. Results: There were significant associations between the SOMP-I-scores and Bayley-III motor index per every assessment age. At 4 months, both level and quality were independently associated with a later motor outcome, OR for level was 1.26 (95% CI = 1.08-1.50, P = .002) and for quality, 0.75 (95% CI = 0.63-0.90, P = .002). Quality was independently associated with the Bayley-III motor index at 6 and 10 months: OR 0.080 (95% CI = 0.67-0.95 P = .010) and 0.79 (95% CI = 0.64-0.97, P = .026). Conclusion: Both SOMP-I domains, level and quality, are markers to identify motor problems early. Quality became more important with age.

Clinical utility of the Structured Observation of Motor Performance in Infants within the child health services

AimThis study aimed to evaluate the clinical utility of the Structured Observation of Motor Performance in Infants (SOMP-I) when used by nurses in routine child healthcare by analyzing the nurses’ SOMP-I assessments and the actions taken when motor problems were suspected.MethodInfants from three child health centers in Uppsala County, Sweden, were consecutively enrolled in a longitudinal study. The 242 infants were assessed using SOMP-I by the nurse responsible for the infant as part of the regular well-child visits at as close to 2, 4, 6 and 10 months of age as possible. The nurses noted actions taken such as giving advice, scheduling an extra follow-up or referring the infant to specialized care. The infants’ motor development was reassessed at 18 months of age through review of medical records or parental report.ResultsThe assessments of level of motor development at 2 and 10 months showed a distribution corresponding to the percentile distribution of the SOMP-I method. Fewer infants than expected were assessed as delayed at 4 and 6 months or deficient in quality at all assessment ages. When an infant was assessed as delayed in level or deficient in quality, the likelihood of the nurse taking actions increased. This increased further if both delay and quality deficit were found at the same assessment or if one or both were found at repeated assessments. The reassessment of the motor development at 18 months did not reveal any missed infants with major motor impairments.InterpretationThe use of SOMP-I appears to demonstrate favorable clinical utility in routine child healthcare as tested here. Child health nurses can assess early motor performance using this standardized assessment method, and using the method appears to support them the clinical decision-making.

“…The diagnostic scales used in clinical practice are based on the subjective evaluation of the diagnostician and, consequently, on his or her experience and knowledge (Ciuraj et al 2019). The most popular scales include Test of Infant Motor Performance (TIMP) (Nuysink et al 2013), General Movements Assessment (GMA) (Einspieler & Prechtl 2005), Vojta's kinesiological diagnostics (Gajewska et al 2006), Alberta Infant Motor Scale (AIMS) (Piper et al 1992 (Montgomery et al 2017;Johansen et al 2017). The described situation inspires the search for an objective, non-invasive, and effective measurement system (Ciuraj et al 2019;Kieszczyńska et al 2018).…”

Background: The assessment of spontaneous activity of infants is of fundamental importance to the diagnosis and prediction of abnormal psychomotor development in children. Comprehensive and early diagnosis allows for quick and effective treatment and therapy. Subjective methods are based on the knowledge and experience of the diagnostician. The lack of objective methods to assess the motor development of infants makes it necessary to search for solutions for reliable, credible, and reproducible assessment expressed in numerical or pictorial terms. This study discusses the possibilities of pictorial standardization and optimization of measurable infant behavior based on video recordings. Methods: The authors attempt to perform computer analysis of spontaneous movements depending on the left, right, and front head position. The study was based on data of 26 healthy infants aged 7 to 15 weeks, with three infants included in an in-depth analysis. The selected films represented the input data for the parameters used as the author's temporal and spatial characteristics describing the global movements of the upper and lower limbs. The obtained videos were used as the input data for the algorithm of automatic detection of characteristic points using the OpenPose library. Results: The following movement characteristics were analysed: Factor of Movement's Area (FMA) ("amount of movement in the movement"), Factor of Movement's Shape (FMS) ("circularity” or "ellipticity" of the movement), Center of Movement's Area (CMA) ("inward and outward" and "up and down" movements). Preliminary analysis of the videos showed that the activity of the limbs, especially the upper limbs, may depend on the position of the head.Conclusions: The movement behavior of the infants varies in terms of the range and quality of movement, depending on age and head position.

The Structured Observation of Motor Performance in Infants has convergent and discriminant validity in preterm and term infants

Abstract: Convergent validity and discriminant validity of the SOMP-I were supported in preterm and term infants and facilitates early identification of infants with atypical motor development.
