Synkinesis

Brief summary

This proposal will prospectively assess the social, physical, and emotional recognition function in participants with synkinesis. It will measure the effectiveness of neuromuscular retraining therapy to improve muscle coordination compared to chemodenervation, the more established treatment modality, in a single-blinded, randomized control trial using clinician- and patient-reported outcomes measures. The hypothesis tested is that participants undergoing neuromuscular retraining therapy will achieve greater improvement on clinical outcome measures as compared to participants receiving chemodenervation. In this clinical trial, 36 participants undergoing treatment for synkinesis will be enrolled into one of two treatment arms: chemodenervation or neuromuscular retraining therapy. Participants can expect to be on study for approximately 8 months. Participants who enroll in this mixed methods investigation will be recruited from patients of the University of Wisconsin Facial Nerve Clinic and also be enrolled in a another study for assessment \[Perception of Emotion Expression in Clinical Populations with Facial Paralysis, IRB approval 2015-0366\].

Detailed description

Facial nerve paralysis is a devastating event that in up to 30% of cases may result in chronic weakness and/or the disfiguring condition of synkinesis, a long-lasting muscle discoordination of facial movement caused by aberrant facial nerve regeneration after facial nerve paralysis. This is believed to have a detrimental effect on social interactions, mental health, and quality of life. Neuromuscular retraining therapy and ipsilateral chemodenervation into discoordinated muscles by injection (onabotulinumtoxinA/Botox, Allergan or incobotulinumtoxinA/Xeomin, Merz) are two common treatments for the abnormal muscle movements found in synkinesis. No study has compared the effectiveness of these treatment modalities for synkinesis. Retrospective data including our series at the University of Wisconsin Facial Nerve Clinic show significant benefit of retraining therapy using clinician- and patient-reported outcome measures. However, the manner in which this therapy may be optimized for use in treatment of the sequelae of facial paralysis is unclear. While literature shows beneficial improvement in outcomes with chemodenervation in prospective studies, no study has explored the effectiveness of physical therapy for synkinesis in a controlled, prospective manner. Further, the efficacy of therapy has not been shown to improve recognition and emotional information interpretation, both thought to be impaired in synkinesis. This study has 3 specific aims: AIM 1: Determine the effect of neuromuscular retraining or chemodenervation on clinician-reported and patient-reported outcomes. The primary outcome measure after four and eight months of treatment will be the clinician-reported Sunnybrook Facial Grading System (SFGS) scored on participant videos by blinded reviewers. Further, the investigators seek to measure the efficacy of treatment with existing patient-reported instruments. A correlation of clinician-reported outcome measure changes to changes in patient-reported instruments with treatment will be calculated, including the widely utilized disease specific Synkinesis Assessment Questionnaire (SAQ) and Facial Clinimetric Evaluation Scale (FaCE), and with two disease non-specific instruments, the Hospital Anxiety and Depression Scale (HADS), and Brief-Illness Perception Questionnaire (BIPQ). The efficacy of our clinical intervention will be measured with social-perceptual and mental health outcome measurement before and after treatment (AIM 3). AIM 2: Determine the social, emotional, and functional burden of synkinesis, not captured in current patient-reported outcome measures as well as effect of treatment. Qualitative interviews with individual participants collected before treatment, after four months of treatment, and after eight months of treatment will be analyzed to study the burden of disease, experience with treatment, and potential differences in both treatments. The primary outcome is to identify the domains that may be missing from existing patient-reported measures collected in AIM 1. To do this, findings to assessment domains (i.e. decreased engagement, negative mood, etc.) in the FaCE, SAQ, and the two disease non-specific instruments, HADS and BIPQ will be compared. The investigators will then evaluate their findings based on domains in Patient-Reported Outcomes Measurement Information System (PROMIS) measures, an NIH-supported collection of validated and standardized scales. AIM 3: Quantify the disruption in social functioning caused by synkinesis using innovative social-perceptual outcomes and emotion recognition tasks. Prior to treatment, participants will enroll in IRB Protocol 2015-0366 and complete a series of social functioning and mental health instruments and emotion expression recognition tasks. Results will be compared to control participants without facial disability to reveal the social-perceptual impairment attributable to synkinesis. Repetition of these tasks after four months of either treatment may show improvement in recognition and emotional information interpretation when compared to initial measurements.

Interventions

OTHERNeuromuscular Retraining Therapy (4 months)

Neuromuscular retraining is an intervention where facial therapists utilize voluntary input to access improved movement patterns in patients with synkinesis.

Change in Sunnybrook Facial Grading System (SFGS) Between Baseline and 4 Month Scoringup to 4 monthsParticipants will be videotaped as part of routine care and undergo a blinded SFGS scoring. Scoring is determined by a voluntary movement score (5-items scored from 1-5 where 1 is unable to move and 5 is complete voluntary movement - total range of 5-25, multiplied by 4, where a higher score is a better outcome) minus a resting symmetry score (total of 0-4 where 0 is normal and 4 indicates some asymmetry, multiplied by 5, where a lower score is a better outcome) minus a synkinesis score (5-items scored from 0-3 where 0 is none and 3 is severe, a lower score is a better outcome). Total possible range of scores is 20-100, with a higher score being a better outcome. Scores from baseline will be compared to those at 4 months and the change between the two will be reported.

Qualitative analysis will proceed concurrently with data collection to allow identified themes to be explored in subsequent interviews. In qualitative research this involves both coding the written transcripts and then modeling the coded data. All team members will analyze the data and look for themes and trends that are emergent from the data. For post-treatment interviews, directed content analysis will be employed as findings from pre-treatment interviews will guide analysis of post-treatment interviews while capturing emergent themes that come up in the data.

Time frame: up to 4 months

Pre-Treatment Qualitative Interviews

Qualitative analysis will proceed concurrently with data collection to allow identified themes to be explored in subsequent interviews. In qualitative research this involves both coding the written transcripts and then modeling the coded data. All team members will analyze the data and look for themes and trends that are emergent from the data. For the pre-treatment interviews, Conventional Content Analysis will be employed to obtain direct information from study participants without imposing preconceived categories or theoretical perspectives.

Time frame: up to 8 months

Population: Data were not collected.

Synkinesis Assessment Questionnaire (SAQ) at 4 Months

The SAQ is a 9-item questionnaire where each item is scored on a scale from 1-5, 1 is seldom or not at all, and 5 is all of the time, or severely. A higher score indicates a worse outcome. The total range in possible scores is 9-100 (summate scores for questions 1-9/45x100 = SAQ total score) with higher scores indicating more severe facial paralysis symptoms. SAQ scores will be collected as part of routine care throughout the study. Scores will be reported for baseline, 4 months (mid-study), and 8 months (end of study).
