Experiment 1 (Aim 1) will utilize a 16-channel sEMG array to characterize cervical-cranial muscle activity networks in typical speakers at baseline and after a vocal loading task. Flexible laryngoscopy will be performed to exclude any existing pathology and confirm eligibility in the healthy control group. Aim 2 will quantify how cervical muscle networks are perturbed in patients with two different types of dysphonia and examine if standard-of-care treatment restores cervical-cranial muscle networks to more typical states.
In Experiment 2 (Aim 2), the study will measure muscle networks in patients with muscle tension dysphonia before and after a course of voice therapy. Patients with muscle tension dysphonia represent an intact but potentially maladaptive network.
In Experiment 3 (Aim 2), the study will measure patients with unilateral vocal old paralysis, representing a neurologically impaired network, before and after a vocal fold medialization procedure.
