Insights
Prism adaptation using game-based tasks is effective for improving visuospatial skills in children with unilateral brain lesions. This approach shows promise for pediatric interventions targeting neglect and visuospatial deficits.
Area of Science:
- Neuroscience
- Pediatric Rehabilitation
- Visuospatial Cognition
Background:
- Unilateral visuospatial deficits are common in children with brain damage.
- Prism adaptation effectively treats unilateral neglect in adults, but its pediatric application is unexplored.
- This study investigates prism adaptation feasibility in children with unilateral brain lesions.
Purpose of the Study:
- To evaluate the feasibility of prism adaptation in children with unilateral brain lesions.
- To compare a game-based procedure with an ecological task for prism adaptation in pediatric patients.
- To assess the efficacy of prism adaptation in improving visuospatial function in children.
Main Methods:
- Twenty-one children with unilateral brain lesions were randomized into prism or control groups.
- Participants engaged in bimanual tasks using either game-based or ecological procedures.
- After-effects of prism adaptation were measured using visuoproprioceptive and proprioceptive tests.
Main Results:
- Both game and ecological tasks yielded comparable after-effects.
- Prismatic glasses induced a significant shift in visuospatial coordinates, unlike neutral glasses.
- This demonstrates a measurable effect of prism adaptation in the pediatric cohort.
Conclusions:
- Prism adaptation utilizing game-based tasks is an effective method for inducing after-effects in children with unilateral brain lesions.
- Further research is warranted to explore repetitive prism adaptation as a therapeutic intervention for pediatric visuospatial deficits and neglect.
Introduction:
Unilateral visuospatial deficits have been observed in children with brain damage. While the effectiveness of prism adaptation for treating unilateral neglect in adult stroke patients has been demonstrated previously, the usefulness of prism adaptation in a pediatric population is still unknown. The present study aims at evaluating the feasibility of prism adaptation in children with unilateral brain lesion and comparing the validity of a game procedure designed for child-friendly paediatric intervention, with the ecological task used for prism adaptation in adult patients.
Methods:
Twenty-one children with unilateral brain lesion randomly were assigned to a prism group wearing prismatic glasses, or a control group wearing neutral glasses during a bimanual task intervention. All children performed two different bimanual tasks on randomly assigned consecutive days: ecological tasks or game tasks. The efficacy of prism adaptation was measured by assessing its after-effects with visual open loop pointing (visuoproprioceptive test) and subjective straight-ahead pointing (proprioceptive test).
Results:
Game tasks and ecological tasks produced similar after-effects. Prismatic glasses elicited a significant shift of visuospatial coordinates which was not observed in the control group.
Conclusion:
Prism adaptation performed with game tasks seems an effective procedure to obtain after-effects in children with unilateral brain lesion. The usefulness of repetitive prism adaptation sessions as a therapeutic intervention in children with visuospatial deficits and/or neglect, should be investigated in future studies.
