What You Need to Know Before You Apply

What is the purpose of this trial?

The long-term goal is to transform the diagnosis and treatment of dysphonia by elucidating cervical and cranial neuromuscular mechanisms underlying typical and disordered voicing. The overall objective of this application is to propose and evaluate a novel objective spectrotemporal diagnostic tool measuring functional cervical-cranial muscle network activity in typical and disordered speakers.The purpose of this study is to improve our understanding of how the vocal tract and the muscles of the larynx and the head work at baseline and after vocal fatigue.

Are You a Good Fit for This Trial?

This trial is for adults over 18 with muscle tension dysphonia or unilateral vocal cord paralysis, recommended for voice therapy or vocal fold injection medialization. Participants must be able to consent and complete assessments. Excluded are those with allergies to the device, 'smart' implants, recent head/neck surgery, open wounds near sensors, abnormal laryngeal structures, or involvement in other investigational studies.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Baseline Assessment

Baseline sEMG measurements and vocal tasks are conducted to assess cervical-cranial muscle network activity

1 visit
1 visit (in-person)

Treatment

Participants undergo vocal loading tasks and receive interventions such as voice therapy or vocal fold medialization

2 months
2 visits (in-person)

Follow-up

Participants are monitored for changes in pitch, loudness, and phonatory effort after treatment

2 months
2 visits (in-person)

What Are the Treatments Tested in This Trial?

Interventions

  • Computational Cranial and Cervical Muscle Network
Trial Overview The study aims to develop a new diagnostic tool by measuring muscle activity in the neck and head using surface electromyogram (sEMG) and flexible laryngoscopy. It will compare typical voicing against disordered conditions before and after vocal fatigue to understand neuromuscular mechanisms better.
