- Objectives: To conduct a systematic review to examine the scientific literature for rehabilitation/habilitation among individuals with pediatric-onset spinal cord injury (SCI). Methods: A literature search of multiple databases (i.e., PubMed/MEDLINE, CINAHL, EMBASE, PsychINFO) was conducted and was filtered to include studies involving humans, published as full-length articles up to December 2020, and in English. Included studies met the following inclusion criteria: (1) >= 50% of the study sample had experienced a traumatic, acquired, nonprogressive spinal cord injury (SCI) or a nontraumatic, acquired, noncongenital SCI; (2) SCI onset occurred at <= 21 years of age; and (3) sample was assessed for a rehabilitation/habilitationrelated topic. Studies were assigned a level of evidence using an adapted Sackett scale modified down to five levels. Data extracted from each study included author(s), year of publication, country of origin, study design, subject characteristics, rehabilitation/habilitation topic area, intervention (if applicable), and outcome measures. Results: One hundred seventy-six studies were included for review (1974-2020) with the majority originating from the United States (81.3%). Most studies were noninterventional observational studies (n = 100; 56.8%) or noninterventional case report studies (n = 5; 2.8%). Sample sizes ranged from 1 to 3172 with a median of 26 (interquartile range [IQR], 116.5). Rehabilitation/habilitation topics were categorized by the International Classification of Functioning, Disability and Health (ICF); most studies evaluated ICF Body Function. There were 69 unique clinical health outcome measures reported. Conclusion: The evidence for rehabilitation/habilitation of pediatric-onset SCI is extremely limited; nearly all studies (98%) are level 4-5 evidence. Future studies across several domains should be conducted with novel approaches to research design to alleviate issues related to sample sizes and heterogeneity.

- Neuronal network formation in the developing nervous system is dependent on the accurate navigation of nerve cell axons and dendrites, which is controlled by attractive and repulsive guidance cues. Ephrins and their cognate Eph receptors mediate many repulsive axonal guidance decisions by intercellular interactions resulting in growth cone collapse and axon retraction of the Eph-presenting neuron. We show that the Rac-specific GTPase-activating protein α2-chimaerin binds activated EphA4 and mediates EphA4-triggered axonal growth cone collapse. α-Chimaerin mutant mice display a phenotype similar to that of EphA4 mutant mice, including aberrant midline axon guidance and defective spinal cord central pattern generator activity. Our results reveal an α-chimaerin-dependent signaling pathway downstream of EphA4, which is essential for axon guidance decisions and neuronal circuit formation in vivo.
