Summary
Adding concurrent motor tasks to fusional vergence therapy can improve automaticity. This allows patients to maintain binocular function while attention is directed elsewhere, enhancing overall cognitive processing.
Area of Science:
- Ophthalmology
- Neuroscience
- Vision Science
Background:
- Fusional vergence therapy typically demands significant patient attention.
- High attentional demands may detract from cognitive processing.
- Developing automaticity in fusional vergence is key for efficient visual function.
Purpose of the Study:
- To investigate a method for enhancing fusional vergence automaticity.
- To assess the impact of concurrent motor demands on fusional vergence training.
Main Methods:
- Retrospective pilot study of patient records.
- Inclusion of a concurrent motor demand (rebounder bouncing) during fusional vergence therapy.
Main Results:
- Most patients showed initial decreased fusional vergence ranges with concurrent tasks, followed by improvement with practice.
- 75% of base-out and 57.1% of base-in protocols showed this pattern.
- Some patients (28.6% base-in) did not improve, while others (25% base-out, 14.3% base-in) showed no initial decrement.
Conclusions:
- Maximum automaticity in fusional vergence may not be achieved with full attention to the task alone.
- Concurrent distractors can help automate fusional vergence performance.
- Increased automaticity frees attentional resources for other cognitive tasks.
