Clinical Trial Summary

This study will test laryngeal adaptation in speech and swallowing function in healthy adults, in patients with cerebral stroke, and in patients with spinocerebellar ataxia type 6. The findings from this proposal will be the first step toward implementing rehabilitation techniques that help patients to prevent speech and swallowing errors before they occur.

Intervention

Device:
• Intermittent Perturbation to Continuous Perturbation
Manipulate the Movement Planning Period (MPP), by interrupting sensory predictions by removing e-stim during the inter-trial interval (Intermittent Perturbation), followed by a washout/de-adaptation period.
• Continuous Perturbation to Intermittent Perturbation
Manipulate the Movement Planning Period (MPP), by keep sensory input about the perturbation constant by maintaining e-stim during the inter-trial interval.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Laryngeal Adaptation in Speech	To differentiate laryngeal adaptation during speech among cerebral stroke, SCA6, and healthy controls when vocal loudness is perturbed with expiratory loading.	Day 1
Primary	Laryngeal Adaptation in Swallowing	To differentiate laryngeal adaptation among cerebral stroke, SCA6, and healthy controls when swallowing is perturbed with neck surface electrical stimulation to restrict laryngeal elevation.	Day 1
