Learning Disabilities

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Summary

Dyslexic children show poorer postural control, with greater body sway, compared to non-dyslexics. However, oculomotor and attention training may improve this mild postural instability in individuals with dyslexia.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Biomechanics

Background:

  • Postural control is linked to visual-motion processing, which may be impaired in dyslexia.
  • Clinical and fundamental studies present conflicting evidence regarding posture abnormalities in dyslexics.

Purpose of the Study:

  • To investigate posture stability in dyslexic children during quiet stance.
  • To explore the relationship between visual-motion processing, oculomotor control, and postural stability in dyslexia.

Main Methods:

  • Posture stability was assessed in 13 dyslexic and 13 non-dyslexic children using center of pressure (COP) measurements.
  • Experiment 1: Quiet stance at near and far distances.
  • Experiment 2: Posture stability during active vergence movements.
  • Experiment 3: Eye movement recordings (video-oculography) to assess vergence stability.

Main Results:

  • All children exhibited better stability at near distances.
  • Dyslexic children showed significantly higher COP surface area and greater lateral/antero-posterior oscillations.
  • Active vergence movements partially improved postural stability in dyslexics, but lateral oscillations remained higher.
  • Dyslexics demonstrated difficulties in maintaining stable vergence angles.

Conclusions:

  • Mild postural instability may be present in dyslexic children.
  • Oculomotor control deficits, particularly in vergence stability, contribute to postural instability in dyslexia.
  • Attention and oculomotor training could potentially enhance postural control in individuals with dyslexia.
