Postural Control Among Children with and Without Dyslexia

As Chinese-speaking children with dyslexia typically have different cerebellar sign behavior from non-Chinese-speaking counterparts, this study compared the effect of visual occlusion on the static balance between dyslexic and non-dyslexic children using the Chinese language.

1.Normal IQ(>85, WISC-III)
2.Children with dyslexia assessed by standard tools, performed by psychological-teachers of special education

Exclusion criteria

1.Attention deficit hyperactivity disorder(ADHD)
2.Neurological or psychiatric abnormalities

Treatment and study plan

Eye-opened and Eye-closed

Behavioral

The participants were instructed to perform six 60-second trials (2 conditions × 3 trials) of maintaining an upright stance on a force plate (Kistler Type 9260A, Switzerland) under the eyes open (EO) and eyes closed (EC) conditions. The order of EO and EC was alternated for each participant, and half of the subjects began with the EO (or EC) condition. For both conditions, the participants stood with their feet 1 cm apart on a force plate and their arms relaxed comfortably at their sides.

Primary outcomes

Postural sway analysis

Time frame: through study completion, an average of 1 year

Root mean squared sway amplitude and sample entropy along the AP and ML axes

Secondary outcomes

Stabilogram diffusion analysis of central of pressure

Time frame: through study completion, an average of 1 year

Trajectories of central of pressure will be analyzed with stabilogram diffusion analysis to reveal behavior mechanisms for practice-related variations in feedback and feedforward process for error corrections
