Oculomotor and vestibulo-ocular function post-concussion in children and adolescents
Notice bibliographique
Résumé
Objective: The objectives of this study were (1) to document oculomotor (OM) and vestibulo-ocular (VO) function in children who sustained a concussion and were symptomatic at the time of assessment, and to compare them to that of children with prior concussion who were clinically recovered (asymptomatic) and of uninjured children, and (2) to document the extent to which OM and VO function relate to post-concussion symptom severity in children with symptomatic and asymptomatic concussion. Study Design: A prospective cross-sectional study that included 108 symptomatic/clinically recovered pediatric patients with concussion and 79 healthy youth, between 9 and 18 years of age. Setting: Participants with concussion were recruited from a speciality concussion clinic at the Montreal Children’s Hospital, McGill University Health Center. Methods: OM (smooth pursuit, saccades, anti-saccades and vergence) and VO (average vestibulo-ocular reflex gain) function were acquired with a commercial VR eye-tracking system (Saccade Analytics, InSight software). Post-concussion symptoms were scored with the Post-Concussion Symptom Inventory (PCSI) and were obtained from the patient’s concussion clinic electronic medical records, as were number of previous concussions and premorbid conditions. A series of one-way ANOVA tests and Pearson r correlations were used to address the two objectives. Results: There was a significant main effect at the p<.05 level for vergence during smooth pursuit [ F (2,176) =10.90, p<.05], mean latency during saccades [F (2, 171) = 5.99, p=.003] and mean response delay during anti-saccades [F (2,177=9.07, p.<05]. For VO, there was a significant main effect for average vestibular ocular reflex gain in the horizontal leftward [F (2,168) = 7, p=.001] and rightward directions [W (2,163) = 13.08, p <.05] and vertical upward [F (2,147) = 7.60, p=.001] and downward directions [W (2,144) = 13.70, p <.05]. Significant group differences in OM and VO function highlighted that children with symptomatic concussion showed poorer performance when compared to clinically recovered and healthy children. The Pearson correlation test indicated a significant strong positive correlation between mean saccade error and total PCSI scores for the younger (8-12-year-olds) clinically recovered children. Additionally, children with greater symptom scores on the PCSI tended to preform worse on the OM/VO eye tracking tasks than children who reported lower symptom scores. Conclusion: Our results lead us to conclude that children with symptomatic concussion do indeed present with clinical oculomotor and vestibulo-ocular function impairments and tend to report more severe post- concussion symptoms when compared to healthy and recovered children. The significant group differences between the symptomatic children, recovered and healthy children suggests that VR eye tracking may be an effective tool for identifying OM and VO deficits in the acute phase of concussion. Although more investigation is needed, VR eye tracking of OM and VO function has the potential to provide clinicians with a measurement tool that is both objective and developmentally appropriate for use with children

Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
