Bimanual movements in children with cerebral palsy: a systematic review of instrumented assessments.
Marine Cacioppo, Anthéa Loos, Mathieu Lempereur and 1 others
PMID 36849971WHAT IT FOUND
Motion capture tools distinguish children with CP from typically developing peers during bimanual tasks, but their reliability and ability to track therapy change remain unproven.
Lab protocols fail to capture real-world movement, limiting their use as standalone clinical measures.
Key findings
01Instrumented measures successfully differentiate children with unilateral CP from typically developing peers across various bimanual tasks.
02Reliability and responsiveness of these measures are not sufficiently assessed, preventing their routine use in clinical practice.
03No studies evaluated spontaneous bimanual movement during free play or in the child's home environment.

What it does not show
Protocols were highly heterogeneous, preventing direct comparison between studies. Most participants had unilateral CP; results do not generalize to bilateral CP. No studies reported sample size calculations, so statistical power is unknown. The quality assessment scale used was not previously validated.
Declared interests
None declared.
The easy way to misread this
Do not interpret the ability of these tools to distinguish CP from typical development as evidence they are ready for clinical use. The review found that reliability and responsiveness were largely untested, meaning these measures cannot yet accurately track a child's progress after therapy.
