Short-term sensorimotor training incorporating cognitive tasks for pediatric survivors of posterior fossa tumors: a pilot study.

Abstract

Purpose: Posterior fossa tumors account for half of all childhood brain tumors, prompting the search for effective and affordable interventions to combat the neurocognitive and motor sequelae of the tumor and its treatment. The main aim of this pilot study was to evaluate the feasibility and effects of sensorimotor training incorporating cognitive tasks for a group of pediatric survivors of posterior fossa tumors.

Materials and methods: A total of 48 participants (M_age= 12.3 ± 3.25 years, 41.7% female; 56% with malignant tumors) in remission after completing treatment for posterior fossa tumors were enrolled. Participants received 3 weeks of sensorimotor training targeting visual-motor and cognitive abilities on a FitLight Trainer™. The protocol consisted of 2-3 15-minute training sessions per week, with each session including tasks designed to promote: (1) eye-hand and eye-foot coordination and motor control (simple sensorimotor reaction task); (2) inhibitory control (inhibition task); (3) inhibitory control and working memory (color task).

Results: Participants completed an average of six sessions, indicating a moderate adherence rate. Results showed a significant reduction in visuomotor reaction time across age and tumor subgroups in nearly all tasks, which might indicate improvement in the targeted functions, with performance characteristics varying across subgroups.

Conclusion: The results suggest that training might be a feasible intervention to promote visual-motor performance in pediatric survivors of posterior fossa tumors across age and tumor type groups, however, further research should address the assessment issues and other limitations of the present study, to provide a more substantial justification for the use of this training.
