Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: High-volt electrical stimulation
Plan to use a monophasic waveform having 100µmsec pulse duration, at 35 Hz using tolerated voltage to generate a contraction a total of 20 minutes. The stimulation will have 10 seconds on time, 30 seconds off time and 2 second ramp up and down. Electrical stimulation will be produced with the Orthostim 3 device (VQ Ortho Care). The cathode will be placed on the ipsilateral muscle to stimulate and the anode over the ipsilateral mastoid region. Four facial muscles will be stimulated: 1)frontalis, 2) orbicularis oculi, 3) zygomaticus major, and 4) orbicularis oris. The voltage is turned up by the participant until he or she can see twitches or as high as tolerated. Ten contractions in each muscle group will be performed or 5 minutes per muscle if no contraction is achieved. |
An electrical stimulation device with adjustable voltage.
Useful for both Sensory and Subsensory
|
Placebo Comparator: Subsensory electrical stimulation
Plan to use the same device and settings to provide placebo treatment by delivering minimal electricity. The settings will be the same as the intervention except the voltage will be subsensory. ie. below the minimum at which patients feels any effect of the current. The voltage is turned down two clicks from the voltage at which the participant can first notice any electricity or at the minimal setting. |

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Recovery at 3 Months as Measured From Facial Photos With Different Facial Expressions
Time Frame: 3 months
|
To evaluate for complete recovery, standardized photos of patients at rest, and during movement, will be evaluated by three treatment-blinded otolaryngologists.
Total number of patients fully recovered over number of participants will be reported.
|
3 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
House Brackmann Scale
Time Frame: Baseline, and 3 months
|
Determined by three blinded otolaryngologist reviewing facial photos of patients with smile and eye closure.
Reported as an average of the three scores.
The scales ranges from 1 (normal) to 6 (most severe dysfunction)
|
Baseline, and 3 months
|
Patient Reported Quality of Life in Relation to Facial Synkinesis Measured by the Synkinesis Assessment Questionnaire (SAQ)
Time Frame: Baseline, 3 months and 6 months
|
Quality of life is in part measured in this study using the patient reported Synkinesis Assessment Questionnaire (SAQ).
The instrument consisting of 10 items asks participants how difficult certain facial activities are.
Based on the average score for each domain the test gives a score between 20 (no synkinesis) to 100 (severe synkinesis, all the time).
|
Baseline, 3 months and 6 months
|
Patient Reported Global Quality of Life Specific to Facial Paralysis
Time Frame: Baseline, 3 months and 6 months
|
Measured by the validated quality of life patient reported questionnaire Facial Clinimetric Evaluation (FaCE) Scale with a scale from 0 (normal) to 100 (severe dysfunction).
The scale encompasses facial movement, facial comfort, oral function, eye comfort, lacrimal control, and social function.
|
Baseline, 3 months and 6 months
|
Objective Measurements of Brow Elevation
Time Frame: Baseline and in 3 months
|
Measuring brow elevation using the MEEI FACE-gram program reported as the millimeters in decreased elevation in comparison to the unaffected side
|
Baseline and in 3 months
|
Eye Closure
Time Frame: Baseline and 3 months
|
Measuring in millimeters of the eyelids remaining open during maximal eye closure using the MEEI FACE-gram program
|
Baseline and 3 months
|
Smile Excursion
Time Frame: Baseline and 3 months
|
Measuring oral commissure exclusion using the MEEI FACE-gram program reported as the change in millimeters in the distance between the midline of the lower lip and the oral commissure in comparison between rest and smile
|
Baseline and 3 months
|
Facial Symmetry at Rest
Time Frame: Baseline and 3 months
|
Measured by facial asymmetry index (FAI) at rest in photos which is calculated as the difference in the distance from the lateral canthus to the oral commissure between the affected and unaffected side.
In the scale 0 equals no difference between sides and perfect symmetry.
The closer a number is to 0, the higher the symmetry is.
Ranges have not been published for this scale.
FAI does not have a maximum score.
|
Baseline and 3 months
|
Facial Symmetry During Smile
Time Frame: Baseline and 3 months
|
Measured by facial asymmetry index (FAI) during smile in photos which is calculated as the difference in the distance from the lateral canthus to the oral commissure between the affected and unaffected side.
In the scale 0 equals perfect symmetry and no difference in sides.
The closer a number is to 0, the greater the symmetry.
Ranges have not been published for this scale.
FAI does not have a maximum score.
|
Baseline and 3 months
|
Patient Tolerability
Time Frame: 3 months
|
Measured by a visual analog scale (VAS) which ranged from 0 to 10 where 0 stands for completely comfortable and 10 to very uncomfortable.
A questionnaire designed by research team using a Likert's scale was created to measure patient tolerability.
|
3 months
|
Self Reported Subject Adherence
Time Frame: 3 months
|
Percentage of subjected who reported full adherence, partial adherence and non-adherence confirmed by comparing to the daily diary of use.
|
3 months
