Motor repertoire is age-inadequate in infants with cystic fibrosis.

Abstract：

BACKGROUND:General movements (GMs) in infants occur as fidgety movements (FMs) between postterm 9 and 20 weeks. We aimed to evaluate FMs and motor repertoire in infants with cystic fibrosis (CF) and their relation with clinical findings. METHODS:Demographic and clinical characteristics were recorded. FMs and motor repertoire were analyzed from a 5-min video recording of each infant. Videos were rated based on the Prechtl General Movement Assessment and motor optimality score (MOS) was calculated. RESULTS:The analysis included 18 infants with CF and 20 healthy infants at postterm age of 3-5 months. MOS was significantly lower in the infants with CF compared to controls (p < 0.05). Fifty percent of the infants with CF had abnormal or absent/sporadic FMs. MOS was negatively associated with hospitalization duration (r = -0.378, p = 0.036); and positively associated with vitamin A level in CF infants (r = 0.665, p = 0.026). CONCLUSIONS:Infants with genetically anticipated severe CF phenotype tended to have lower MOS. MOS may be used in addition to genetic testing to predict disease severity in infants with CF. Infants with CF, absent/sporadic FMs, and lower MOS could be considered for planning specific age-adequate early intervention programs. IMPACT:Motor repertoire was age-inadequate in infants with cystic fibrosis (CF).50% of infants with CF had abnormal or absent/sporadic fidgety movements (FMs).Motor optimality score (MOS) was positively associated with vitamin A level and negatively correlated with hospitalization duration in infants with CF.MOS tended to decrease as genetically anticipated disease severity increased; thus, MOS might enable us to predict disease severity in CF. The relationship between motor repertoire and phenotype and genotype is unclear and warrants further study.CF infants with absent/sporadic FMs, and lower MOS could be considered for planning early intervention.
