摘要
Balance difficulties are an enduring feature of dyslexia research, however results have been inconsistent. We propose that between-study heterogeneity may be attributable to variability in balance tasks, balance measurement, participant age, and inclusion of comorbid disorders such as ADHD. This study attempted to clarify these issues, employing quantitative, continuous measures of balance and blindfolded balance, and using both adult and child participants without comorbid ADHD. Eighty-seven individuals participated: dyslexic adults (n = 17), matched adult controls (n = 30), dyslexic children (n = 16) and matched child controls (n = 24). The study found significant balance deficits for the child dyslexic group in the eyes-open task and a result approaching significance in the blindfolded task. By contrast, the adult dyslexic group showed significant deficits in the blindfolded task only. This result is interpreted in terms of lack of sensitivity of the non-blindfolded balance task for adults, owing to ceiling effects. This highlights the need for the use of age-appropriate tests, and may explain some of the heterogeneity in the literature. It is concluded that there is a significant incidence of balance difficulties in children and adults with dyslexia, even for those without comorbid attention deficit.
