bilateral integration
The neurological ability to coordinate and use both sides of the body together in a smooth, simultaneous, or alternating fashion.
Full Definition
Bilateral integration, also referred to as bilateral coordination, is a foundational sensory integrative function that involves the ability to use both sides of the body together in a coordinated manner. This neurological process requires effective communication between the brain's hemispheres through the corpus callosum and involves three levels: symmetrical bilateral integration (both sides doing the same thing simultaneously), asymmetrical bilateral integration (both sides doing different but complementary actions), and crossed lateral integration (reciprocal movements across the midline). Deficits in bilateral integration can impact activities requiring two-handed coordination such as cutting with scissors, riding a bicycle, or typing. These difficulties are often seen in children with learning disabilities, developmental coordination disorder, or sensory processing difficulties, making bilateral integration a key focus in pediatric occupational therapy assessment and intervention.
Usage
Usage note: Often assessed through standardized tests like the Sensory Integration and Praxis Tests (SIPT).
In Context
- "The child demonstrated poor bilateral integration during activities requiring coordinated use of both hands, such as manipulating toys or using scissors." — Sensory integration evaluation
- "Treatment activities focused on improving bilateral integration through graduated two-handed tasks and cross-lateral movement patterns." — Pediatric intervention plan
