An Investigation Of Upper Extremity Motor Impairments In Children Diagnosed With Autism Spectrum Disorder: Motor Planning Vs Motor Execution, Patrick Anthony Cereceres

Open Access Theses & Dissertations

---

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder typically diagnosedwhen a child displays social and communication impairments, repetitive behaviors, and rhythmic movements like hand flapping. This disorder is unique because of the high variability of symptoms displayed between each individual who is diagnosed. Because of this, no neurological or physiological test exists to diagnose a child with ASD. Current diagnostic tests are various forms of interviews or observations which an experienced clinician must administer. While these tests have been instrumental in diagnosing children with ASD, many go undiagnosed, which can be detrimental as they transition into adulthood. Current literature indicates …
