Trial summary

Purpose of the trial is to study the activations of paralyzed facial muscles in a unilateral facial nerve palsy with a multi-channel electrical stimulator. The principle of the device is to measure muscle activity of the healthy side of the face by surface electromyography (EMG) and to use this information to… Read more about this study

About this study

Official title: Mimetic Interfaces - Toispuoleisen Kasvohermohalvauksen Kojeellinen Kuntoutus Terveen Puolen Lihasaktiviteettiohjauksella. Stimulaattorin Prototyypin Testaus terveillä koehenkilöillä ja Kasvohermohalvauspotilailla.

Purpose of the trial is to study the activations of paralyzed facial muscles in a unilateral facial nerve palsy with a multi-channel electrical stimulator. The principle of the device is to measure muscle activity of the healthy side of the face by surface electromyography (EMG) and to use this information to stimulate the corresponding muscles of the paralyzed side. The ultimate goal is to develop a prosthetic device for persons with a facial nerve palsy.

The trial consists of several different studies. The studies' aims are 1. To study activations of paralyzed facial muscles by the electrical stimulation. 2. To study different stimulation pulse waveforms, frequencies, and electrode placement and their effect on the muscle activations and the tolerability of the stimulation. 3. To study whether a symmetrical movement on the paralyzed side can be achieved with electrical stimulation when compared to the movements of the healthy side. 4. To study tolerability of stimulation-elicited eye blink when watching a film and the effect of the stimulation-induced blink on the eye symptoms, the visual acuity, and the effects of the stimulation on the lacrimal fluid. 5. To develop a method for facial pacing, i.e. measuring the muscle activations on the healthy side of the face and to use this information to stimulate and activate the healthy side of the face.

Forty subjects with a chronic facial nerve palsy are recruited to the studies. Each subject can participate in one or several studies. Another forty subjects with an acute facial nerve palsy are recruited to the study on the tolerability and effect on the eye symptoms. Additionally, altogether ninety healthy volunteers are recruited to the studies in order to gather preliminary information on the tolerability and the effects of the stimulations.

What is being measured

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

  1. Amplitudee of the movement elicited by electrical stimulation

    The offline video analysis is done to determine the current threshold at which a movement of the target muscle is produced. Possible activations of the other muscles alongside the target muscle are also observed. The amplitude of the movement is analyzed offline from a video recording either visually by the investigators, or measured with a digital ruler. With visual evaluation, the outcome is measured on a rough level, i.e. whether the stimulated movement was larger in amplitude compared to the voluntary movement. With a digital ruler, the results a presented numerically (millimeters). The stimulated activation is compared to the voluntary activation of the muscle. Further, in some sub-studies, the facial activations are evaluated with the Facial Action Coding System.

    Measured: Immediate

Secondary outcomes (4)
  1. Subjective ratings related to the tolerability of stimulations

    The participants evaluate the experienced discomfort and painfulness of the stimulation with a numeric rating scale (NRS).

    Measured: Immediate

  2. Subjective ratings related to acceptability of the stimulated movement

    The participants evaluate the naturalness and symmetry and their satisfaction with the stimulation elicited movement with an NRS.

    Measured: Immediate

  3. Visual acuity

    In substudies concerning the elicitation of eye blink, The visual acuity is measured for both eyes separately with a LogMAR chart before and after the stimulation session.

    Measured: Immediate

  4. Changes in lacrimal fluid

    In substudies concerning the elicitation of eye blink, a lacrimal fluid sample is collected before and after the stimulation session to investigate the possible effects of the stimulation in its constitution.

    Measured: Immediate

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Electrical muscle stimulation in people with Facial Nerve Palsy, run by Tampere University Hospital at 1 site in Finland.

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 2 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 19 Dec 2020. 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 Finland. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Amplitudee of the movement elicited by electrical stimulation (time frame: Immediate). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03496025, which also lists 1 linked publication.

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 19 Dec 2020.
