Electromagnetic articulographic assessment of tongue function in dysarthric and nondysarthric speakers following stroke

The present study investigated tongue kinematics in two groups of participants poststroke, including 10 individuals (8 male, 2 female) with dysarthria (Stroke+D) and 9 individuals (6 male, 3 female) without dysarthria (Stroke-D). Nineteen nonneurologically impaired individuals matched for age and gender served as controls. Each participant was assessed using electromagnetic articulography (AG 200) during five repetitions of the tongue-tip sentence Tess told Dan to stay fit and tongue-back sentence Karl got a croaking frog. Kinematic parameters calculated included velocity, acceleration/deceleration, distance moved, and duration of movement across the sentence productions. Statistical analysis revealed a significant difference (
