CP Motor Assessment and Movement Quality

This cluster shows how to spot small and big movement problems in kids with cerebral palsy. It tells us how to measure balance, muscle control, and walking steadiness with simple tests and wearables. BCBAs can use these tools to pick the right goals and see if therapy is helping. When we know exactly what motor skill is shaky, we can teach better and make playtime safer and more fun.

Key Findings

What 226 articles tell us

  1. About half of school-age children with CP have clinically significant sleep disturbances, and sleep quality — not just duration — drives next-day mood in teenagers with CP.
  2. Poor visual perception independently predicts weaker bimanual coordination in children with unilateral CP, so assess vision before setting hand-use goals.
  3. Motion-capture cameras added during the Assisting Hand Assessment do not change scores, allowing kinematic data collection without compromising clinical validity.
  4. Manual ability level (MACS) predicts fluid intelligence development in children with CP, with divergence from typical peers beginning around age 4.8 years.
  5. Infants at risk for CP experience markedly more time in supine positions and less time in sitting and standing than typically developing peers, suggesting a need for deliberate posture variety in early intervention.

Frequently Asked Questions

Common questions from BCBAs and RBTs

Very common. Research shows that about half of primary school-age children with CP have clinically significant sleep problems. Screen for epilepsy, pain, and behavior issues when a child with CP has poor sleep.

Yes. Research shows that poor visual perception independently predicts weaker two-handed coordination in children with unilateral CP. A thorough vision assessment should precede bimanual goal-setting.

No. Adding motion-capture cameras to the Assisting Hand Assessment does not change its scores. This means kinematic data can be collected at the same time as the standard clinical assessment without affecting validity.

Deliberate variety. Research shows infants at risk for CP spend too much time in supine positions and not enough in sitting and standing. Structured opportunities for upright weight-bearing throughout the day support the postural development needed for later motor skills.

Current evidence does not support it. A randomized controlled trial of SMART online cognitive training found no improvement in IQ or related skills for children with CP, and program completion was very low.
