The purpose of this paper is to give a brief background to the development of the Lawson Anti Suppression Device (LASD) and its use and report on a preliminary study to determine whether or not treatment with the LASD could benefit those with Dyslexia.
Eighty patients diagnosed as Dyslexic or having learning difficulties were included in the study. The subjects had a full Orthoptic examination and their reading ability was determined by the Watts Reading Test. The subjects then underwent a course of treatment on the LASD with associated home exercises and were reassessed at the conclusion of treatment.
