Abstract: This study investigated range, maximum speed, and duration of tongue and jaw movements in Amyotrophic Lateral Sclerosis (ALS; n=26) and healthy controls (n=16). The study objectives were to examine tongue and jaw movements and their interactions at varying stages of bulbar impairment. The patient group was classified based on the severity of bulbar impairment, via the measure of speaking rate. Kinematic measures were obtained from a sentence produced at individual's comfortable speaking rate and loudness. With ALS, the jaw movements decreased in maximum speed at a later stage of disease compared to the tongue. A positive correlation between range of tongue and jaw movements was observed at an early stage of disease. This correlation was lost at a later stage. Changes in jaw movements may be a compensatory response to tongue impairment. The findings of this study contribute to the understanding of disease progression and speech preservation in ALS.
