[Proprioception changes induced by prismatic glasses wear in children suffering from developmental dyslexia]. / Etude de l'impact du contrôle postural associé au port de verres prismatiques dans la réduction des troubles cognitifs chez le dyslexique de développement.

PURPOSE: To evaluate the consequences of proprioception changes induced by a postural treatment on cognitive disturbances in children suffering from developmental dyslexia. MATERIAL: and methods: Twenty male dyslexic children were treated with prisms within their spectacles and a postural treatment. A control group of dyslexics (n=13) only received spectacles without prisms. All participants were evaluated at the beginning of the study and 6 months later with reading impairment tests and postural examinations. RESULTS: Mean age was 11 years and 5 months in the treated group and 11 years and 7 months in the control group. Four children were excluded from the 6-month analysis because of poor compliance. All dyslexic children presented with a postural deficiency syndrome. In 13 out of 16 treated children, dyslexia was improved at 6 months, especially for the global leximetric test and the reading of regular and irregular words. However, the treatment did not allow a complete recovery of reading ability when compared with age-matched individuals. CONCLUSION: Our results show that postural modifications may favorably influence some clinical signs associated with developmental dyslexia. Further studies with a larger sample and with a longer follow-up period are required to better assess the role of postural treatment in developmental dyslexia.

[Ocular proprioception and developmental dyslexia. Sixty clinical observations]. / Proprioception oculaire et dyslexie de développement. A propos de 60 observations cliniques.

PURPOSE: The objective of this study is to assess proprioception anomalies in postural deficiency syndrome in a group of children suffering from reading impairment. MATERIAL AND METHODS: Sixty male patients with an average age of 11 years and 9 months were included in the study. Initially, they were given a standardized neuropsychological examination, which confirmed the diagnosis of reading impairment. Then after filling out a questionnaire seeking a proprioceptive anomaly, the patients were subjected to a clinical ocular and postural examination consisting of nine precisely described steps. RESULTS: All of the patients recruited for the study presented clinical signs confirming a proprioception disorder found as a part of postural deficiency syndrome. CONCLUSION: This study opens a new direction for research concerning the origin and treatment of at least some reading-impaired children.
