简要总结
The aim of this study is to investigate the effects of gaze-directed oculomotor training incorporated with web-based curriculum readings in Chinese to enhancing fixation, saccade and Chinese characters recognition in schoolchildren with neuromuscular disease associated with congenital oculomotor anomalies.
详细描述
Background: schoolchildren with neuromuscular diseases associated with congenital oculomotor anomalies find problems in reading, even found difficulties in learning their mother-tongue language of Chinese.
Objectives: (1) To test the hypothesis of using gaze-directed oculomotor training (GDOMT) incorporated with curriculum-based reading platform might enhance reading-related oculomotor skills and Chinese characters recognition; (2) To validate the outcome parameters of reading-related oculomotor skills by using remote eye tracker.
Hypothesis: It has been shown that motor learning theory were effective in motor training for children with neuromuscular diseases. Oculomotor training to re-gain reading skills has been found effective for person with acquired brain injury or children with dyslexia, but there is no study on oculomotor training in children with neuromuscular diseases for reading. In this study, we hypothesize that self-initiated gaze-directed oculomotor training via e-reading platform (activated by horizontal saccade from left to right, then fixation dwell about 500ms to activate read-aloud the words phrases in Cantonese) for children with neuromuscular diseases associated with extra-ocular muscles anomalies, will be improved accuracy in fixation and saccade.
Design: Cross-centers prospective Cohort study with quasi-experimental design; subjects of aged 6 to 8, randomly assigned into age-matched treatment group (N=10) or the age-matched control group (N=11).
Methods: Participants (aged 6 to 8) with neuromuscular diseases, ocular health normal, normal intelligence, studying in main-stream special schools for children with physically disabilities were recruited. Participants passed the vision screening then randomized to age-paired matched control group (N=11) and treatment group (N=10). After time 1 measure, they attended reading class as usual. Therapists or teaching staff brought participants to library one by one and let the participant to read hardcopy or e-reading as assigned control or treatment group. Those therapists and teaching staff involved in training did not involve in repeated measures.

入选标准
- •schoolchildren with neuromuscular disease associated with oculomotor anomalies,
- •study in primary school of normal intelligence;
- •age 6 to 8 years old;
- •with native language in Chinese and Cantonese;
- •because of pure oculomotor training, subjects with aphasia may also be recruited;
- •students with normal to mild visual impairment (best corrected visual acuity is better than 20/60);and

排除标准
- •students with mild to moderate intellectual disability;
- •students unable to read Chinese or unable to understand spoken Cantonese;
- •student without oculomotor anomalies who are expected to have accurate fixation and saccades; or student with moderate to severe visual impairment; and
- •students with ADHD, ASD or with behaviour challenging and attention problems, and/or with epileptic seizure elicited by computer flickering light.
