Adverse events reported at the time of botulinum toxin A injection occurred in 6% of injection episodes. Adverse events were reported at follow-up in 22% of injection episodes. Children in Gross Motor Function Classification System (GMFCS) levels IV and V have increased rates of systemic adverse events. Children in GMFCS levels IV and V report less local weakness and pain.
Systemic adverse events occur in 3.6% of botulinum neurotoxin A (BoNT-A) injection episodes. Dysphagia and/or aspiration pneumonia are associated with increased likelihood of systemic adverse events. Multivariable models showed no evidence of association between Gross Motor Function Classification System and systemic adverse events. Multivariable models showed no evidence of association between BoNT-A dose and systemic adverse events.
Normative reference values are essential to identify deviation from normal and evaluate response to treatment. As joint range of motion datasets specific to the pediatric population are infrequently reported in the literature, we determined lower limb passive joint range of motion and bone torsion values from 53 typically developing children aged 4-16 years. Our reference values were consistent with previously published norms, although for some measures, large variability in the literature exists. A clear correlation between joint range and age was observed in most measures. Our results highlight the importance of applying age-matched norms when attempting to identify deviation from normal in the growing child.
Areas of importance identified by families relating to BoNT-A treatment included acknowledgement of individual needs, care coordination, empowerment of families and patients, consistency in service delivery, and the distressing nature of appointment and decision-making. Comparison of the data from the staff patient journey mapping and family interviews suggested that staff have a good but incomplete understanding of the factors important to families, highlighting the need for consumer engagement in establishing family-centred care. The themes identified can guide the provision of family-centred BoNT-A injection clinics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
