About this study

Official title: Effects of Vocal Exercise Following Botox Injection on Voice Handicap and Communicative Participation for Adductor Spasmodic Dysphonia

The purpose of this study is to assess the effect of voice exercise and voice rest on subject's perception of vocal handicap and communicative participation following Botox injections for adductor spasmodic dysphonia.

Read the detailed description

Spasmodic dysphonia (SD) is a neurological disorder characterized by involuntary spasms of the vocal folds resulting in a strained and strangled voice quality. This disorder is quite disabling to patients who suffer from it, particularly affecting patients' quality of life. Botulinum toxin (Botox) has been found to be the most effective treatment for SD. The Botox is injected into the affected muscle resulting in temporary weakening of the muscle. The patients return for injections on average every 3 - 6 months.

There is a suggestion in the literature that increased diffusion of the Botox injectate could improve the effects of the injection. Furthermore, there is literature supporting the use of exercise to increase the diffusion of the Botox. Previous research examined the use of voluntary muscle activity vs. rest immediately following Botox injection for writer's cramp. It was found that the active condition resulted in greater reduction of muscle strength in the injected muscle. Another small study of 9 patients implemented intense exercise comprised of loud reading for one hour and a rest condition of total voice rest for 24 hours. They found that the exercise condition resulted in improved scores on the voice related-quality of life (V-RQOL) measure and concluded that improvement in results of Botox injections may be achieved more consistently with the implementation of exercise following the injection. The exercise used in this study was intense and may be contrary to the overall benefit as the subjects may experience phonotrauma. Timing of the exercise post-injection may also be a factor. Previous literature review revealed combined modality treatment of Botox injection only, Botox with therapy and Botox with sham treatment. They found no significant differences in acoustic stability, V-RQOL, or duration of injection benefit. However, the exercise was initiated 3 weeks post-injection and completed once per week for 5 weeks. Investigators aim to identify what might improve or extend the duration of botox injections for adductor Spasmodic dysphonia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Voice exercise will consist of sustained pitches and pitch glides on a variety of different vocal facilitators.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. A quantifiable difference between the effects of voice exercise vs. voice rest post Adductor Spasmodic Dysphonia botox treatment through analysis of the Voice Handicap Index Questionnaire.

    Pre randomized condition and post 6 week and 12 week, participants will be asked to complete the Voice Handicap Index (VHI).

    The VHI Questionnaire (Voice Handicap Index) is a 30-item questionnaire divided into 3 subsections (Functional, Physical, Emotional) and a Total which measures the effect of voice problems on quality of life. Individuals mark each item on this 30-item questionnaire on a scale from 0-4 (0 being never and 4 being always). Points for each subscale are tallied and a total composite score is also given. A total score of 0-11 is considered Normal, 12-28 is considered Mild Minimal handicap, 29-56 is considered Moderate Handicap, and 57-120 is considered severe handicap.

    Measured: Assessing the change of the post VHI questionnaire between groups. Data will be reported at study completion, an average of 1 year.

Questions about this trial

What is this clinical trial studying?

A study testing Voice Exercise in people with Adductor Spasmodic Dysphonia, run by University of Wisconsin, Madison at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

A quantifiable difference between the effects of voice exercise vs. voice rest post Adductor Spasmodic Dysphonia botox treatment through analysis of the Voice Handicap Index Questionnaire. (time frame: Assessing the change of the post VHI questionnaire between groups. Data will be reported at study completion, an average of 1 year.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 May 2019.
