Subjective visual vertical and postural capability in children born prematurely

Area of Science:

• Developmental neuroscience
• Pediatric motor control
• Sensory-motor integration

Background:

• Preterm birth can impact neurodevelopmental outcomes.
• Postural stability and visual vertical perception are crucial for motor development.

Purpose of the Study:

• To compare postural stability and subjective visual vertical (SVV) performance in very preterm-born children (3-4 years) versus age-matched full-term children.

Main Methods:

• Postural control was assessed using a platform measuring center of pressure (CoP).
• SVV perception was recorded under various conditions (dark, visual perturbation, fixation, eyes closed).

Main Results:

• Preterm children exhibited significantly poorer postural control (larger CoP surface area, medio-lateral length, and mean speed).
• Dual-task conditions negatively impacted postural control in both groups.
• Preterm children showed more variable and less precise SVV values.

Conclusions:

• Impaired postural control and verticality perception in preterm children may stem from immature cortical processes.
• These findings highlight potential challenges in motor control and spatial orientation for very preterm-born individuals.
