NCT03770377

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • 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

  • 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

Interventions

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.
