Validity and cross-cultural differences of the Bayley Scales of Infant and Toddler Development, Third Edition in typically developing infants

BACKGROUND: The Dutch translation of Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III-NL) is a comprehensive tool assessing cognitive, language and motor development in children up to 42 months. AIMS: The first aim of this study was to evaluate concurrent validity of the Bayley-III-NL Gross Motor Scale (GMS) in relation to the Alberta Infant Motor Scale (AIMS). Secondly, divergent validity between the other subscales mutually and the AIMS was investigated. Finally, the importance of population-specific reference values was examined. METHODS AND PROCEDURES: A sample of 122 healthy, typically developing Flemish children (mean age: 9 months 7 days), born full term was assessed with the Bayley-III-NL and the AIMS. OUTCOMES AND RESULTS: Concurrent validity of the Bayley-III-NL GMS and the AIMS was moderate to high (0.59-0.98; p < 0.001). In addition, weak correlations (-0.10-0.27) between the non-motor-Bayley-III-NL subscales and the AIMS were found. Finally, significant differences were found between Bayley-III scores based on Flemish and American norms (p < 0.001), except for fine motor skills (p = 0.11). CONCLUSIONS AND IMPLICATIONS: This study provides support for the concurrent validity of the Bayley-III-NL GMS and divergent validity of the different Bayley-III-NL subscales. Secondly, population-specific reference values should be used to avoid over- and under estimation of infant's development.status: publishe

Diagnostic criteria for DCD: Past and future

The aim of this review was to gather information on how well authors comply to DSM criteria in their description and selection of children with DCD. We investigated which selection criteria were used in experimental and intervention studies published in the last 5 years (2010-2014). Results on 176 papers are summarized. Compliance to the DSM criteria has improved over this time period. In general, detailed information was provided on motor performance using standardized test scores and cut-off values are reported. Method sections were far less detailed about other DSM criteria (i.e., whether motor coordination problems interfered with activities of daily living and how IQ, other medical conditions or co-occurring disorders were checked). Views on how the new DSM-5 criteria could be specified for clinical and research use are discussed.publisher: Elsevier articletitle: Diagnostic criteria for DCD: Past and future journaltitle: Human Movement Science articlelink: http://dx.doi.org/10.1016/j.humov.2015.03.010 content_type: article copyright: Copyright © 2015 Elsevier B.V.

Normative data and percentile curves for the three-minute walk test and timed function tests in healthy Caucasian boys from 2.5 up to 6 years old

The three-minute walk test (3MWT) and timed function tests (TFTs) (rise from floor, 10 m run, climbing and descending four stairs) are currently used to evaluate functional capacity in young boys with neuromuscular disorders. This study aimed to generate normative data in healthy boys aged 2.5 up to 6 years for these tests and to provide percentile curves according to age and height. The relation between the 3MWT, TFTs and anthropometric variables was investigated. In total 179 boys (mean age: 4.1 y ± 1.0) were evaluated across four age (2.5 years; 3 years; 4 years and 5 years) and three height groups: (<100 cm; 100 to <110 cm and ≥110 cm). Three-minute walk distance (3MWD) increased significantly, from 168.4 m (± 18.8) at 2.5 years to 214.5 m (± 26.1) at 5 years and from 172.6 m (±21.8) for children <100 cm to 212.7 m (±26.2) for children ≥110 cm. TFTs times decreased significantly with age and height. Significant correlations between the anthropometric values, 3MWD and TFTs were found (r(s)= 0.55-0.84; p <0.0001). These normative data and percentile curves provide a useful tool in the assessment of functional capacity in young boys. This study also confirms the association between functional tests and anthropometric values.status: publishe

Time Course of Upper Limb Function in Children with Unilateral Cerebral Palsy: A Five-Year Follow-Up Study

Knowledge on long-term evolution of upper limb function in children with unilateral cerebral palsy (CP) is scarce. The objective was to report the five-year evolution in upper limb function and identify factors influencing time trends. Eighty-one children (mean age 9 y and 11 mo, SD 3 y and 3 mo) were assessed at baseline with follow-up after 6 months, 1, and 5 years. Passive range of motion (PROM), tone, muscle, and grip strength were assessed. Activity measurements included Melbourne Assessment, Jebsen-Taylor test, Assisting Hand Assessment (AHA), and ABILHAND-Kids. At 5-year follow-up, PROM (p<0.001) and AHA scores (p<0.001) decreased, whereas an improvement was seen for grip strength (p<0.001), Melbourne Assessment (p=0.003), Jebsen-Taylor test (p<0.001), and ABILHAND-Kids (p<0.001). Age influenced the evolution of AHA scores (p=0.003), with younger children being stable over time, but from 9 years onward, children experienced a decrease in bimanual performance. Manual Ability Classification System (MACS) levels also affected the evolution of AHA scores (p=0.02), with stable scores in MACS I and deterioration in MACS II and III. In conclusion, over 5 years, children with unilateral CP develop more limitations in PROM, and although capacity measures improve, the spontaneous use of the impaired limb in bimanual tasks becomes less effective after the age of 9 years
