Give me a kiss! An integrative rehabilitative training program with motor imagery and mirror therapy for recovery of facial palsy.

BACKGROUND: Peripheral facial nerve palsy (FNP) can have various causes, such as Bell's palsy or after surgery for acoustic neuroma. Rehabilitation is often required but there is no evidence that any rehabilitation approach is more efficacious than another. AIM: The purpose of this research was to determine the effects of neurocognitive-rehabilitative approach through mirror-therapy (MT) and motor-imagery (MI), integrated into the traditional rehabilitation with mime-therapy and myofascial-approach. DESIGN: This study was designed as a double-blind, randomized, controlled trial. SETTING: This study took place from January 2016 to June 2018 at the Unit of Physical Medicine and Rehabilitation of Umberto I Polyclinic Hospital, Rome, Italy. POPULATION: Twenty-two patients were randomized into two groups: the mirror therapy group (N.=11, MT and MI) and the traditional rehabilitation group (N.=11, mime-therapy and a myofascial-approach). METHODS: Outcome assessments were performed before treatment (T0), after one month (T1=10 session, twice/week), after the second and third months (T2=10 twice/week + 5 of MT+MI one/week and T3=10 twice/week + 5 of MT+MI 1/week), and at the 4-week follow-up (T4=2 months follow-up). RESULTS: The analysis of the functional evaluations show that both groups experienced progressive improvement T0 to T3, with stabilization of the results at the follow-up. There was a significant difference in House-Brackmann-Scale scores between T0 and follow-up in favor of the experimental group. In terms of quality of life (FaCE scale), total scores and social function items improved in both groups from T0 to T3. The experimental group obtained better results with regard to quality of life and emotional depression. CONCLUSIONS: The integrated use of MT and MI is efficacious in the rehabilitation of FNP, improving facial physical function. Further studies are needed to determine the predictive factors of the recovery of facial mimic. CLINICAL REHABILITATION IMPACT: The ability of patients with unilateral facial paralysis to recognize and appropriately judge facial expressions and perceive the judgments of others remains underexplored. The likelihood of recovering near-normal facial-function after grade VI facial paralysis is low. Procedures, such as the immediate repair of the facial nerve with an interposed donor graft, might improve facial function in patients with partially injured facial nerves.

Societal Identification of Facial Paralysis and Paralysis Location.

IMPORTANCE: When able to identify facial paralysis, members of society regard individuals with facial paralysis differently. They perceive a decrease in attractiveness, more negative affect, and lower quality of life. However, the ability of lay people in society to accurately identify the presence of facial paralysis has not yet been defined. OBJECTIVE: To determine societal members' ability to (1) identify paralysis in varying degrees of paralysis severity and (2) localize the defect on the face. DESIGN, SETTING, AND PARTICIPANTS: A prospective observational study conducted in an academic tertiary referral center using a group of 380 casual observers was carried out. MAIN OUTCOMES AND MEASURES: Surveys were designed containing smiling and repose images of normal faces and faces with unilateral facial paralysis of 3 severity levels (low, medium, and high) as categorized by House-Brackmann (HB) grade. The photographs were then shown to casual observers in a web-based survey. After reviewing both normal faces and faces with varying degrees of paralysis, they then indicated (1) whether paralysis was present and (2) if so, where the paralysis was on the face. RESULTS: A total of 380 participants (267 [70.3%] women and 113 [29.7%] men with a mean [SD] age of 29 [12] years) successfully completed the survey, viewing 2860 facial photographs in aggregate. The accuracy rate of identifying paralysis increased from low-grade through high-grade paralysis. Facial paralysis was identified in 249 (34.6%) of 719 facial photographs with low-grade paralysis, 448 (63.2%) of 709 with medium-grade paralysis, and 696 (96.7%) of 720 with high-grade paralysis (χ2 = 912.6, P < .001); 6.2% (44/731) of normal faces were incorrectly identified as having paralysis (χ2 = 912.6, P < .001). Participants correctly localized paralysis in 157 (63.0%) of 249 low-grade photographs, 307 (68.5%) of 448 medium-grade photographs, and 554 (79.6%) of 696 high-grade photographs (χ2 = 32.5, P < .001). In general, participants tended to identify facial paralysis more accurately in smiling vs repose faces (48.6% vs 20.6%, 92.4% vs 33.7%, and 96.7% vs 96.6% in low-, medium-, and high-grade paralysis, respectively) (χ2 = 62.2, P < .001; χ2 = 262.6, P < .001; χ2 = 0.0, P = .96, respectively). CONCLUSIONS AND RELEVANCE: The ability of individuals to identify the presence of facial paralysis increased as paralysis severity increased. Further, smiling increased accurate identification. However, even when individuals can identify paralysis, they are not necessarily able to accurately localize the paralysis on a face. This may speak to a phenomenon in which perception of a facial defect comes from a holistic interpretation of a face, rather than a clinically accurate specification of the defect location. These findings are important in the future counseling of patients. LEVEL OF EVIDENCE: NA.

Contemporary solutions for the treatment of facial nerve paralysis.

LEARNING OBJECTIVES: After reviewing this article, the participant should be able to: 1. Understand the most modern indications and technique for neurotization, including masseter-to-facial nerve transfer (fifth-to-seventh cranial nerve transfer). 2. Contrast the advantages and limitations associated with contiguous muscle transfers and free-muscle transfers for facial reanimation. 3. Understand the indications for a two-stage and one-stage free gracilis muscle transfer for facial reanimation. 4. Apply nonsurgical adjuvant treatments for acute facial nerve paralysis. SUMMARY: Facial expression is a complex neuromotor and psychomotor process that is disrupted in patients with facial paralysis breaking the link between emotion and physical expression. Contemporary reconstructive options are being implemented in patients with facial paralysis. While static procedures provide facial symmetry at rest, true 'facial reanimation' requires restoration of facial movement. Contemporary treatment options include neurotization procedures (a new motor nerve is used to restore innervation to a viable muscle), contiguous regional muscle transfer (most commonly temporalis muscle transfer), microsurgical free muscle transfer, and nonsurgical adjuvants used to balance facial symmetry. Each approach has advantages and disadvantages along with ongoing controversies and should be individualized for each patient. Treatments for patients with facial paralysis continue to evolve in order to restore the complex psychomotor process of facial expression.

Central facial paresis and its impact on mimicry, psyche and quality of life in patients after stroke.

AIM: Using functional scales and face video analysis, changes in central facial paresis are monitored in patients with stroke after orofacial therapy and correlations between changes in mimicry, mental function and overall quality of life of patients after stroke are made. MATERIALS AND METHODS: A prospective randomized study of patients after stroke with facial paresis. The functional status of the experimental group of 50 cases with orofacial regulation therapy and 49 control cases without mimicry therapy is observed after four weeks of rehabilitation. RESULTS: Changes in mimicry functions evaluated by the House-Brackmann Grading System (HBGS) clinical range and using 2D video analysis of the distance between the paretic corner of the mouth and earlobe at rest and during smiling were statistically better in the experimental group than in controls. Changes in mental function - depression using Beck Depression Inventory and changes in the quality of life using Bartle index and modified Rankin score (scale) were significantly greater in the experimental group. There was a very close relationship between the changes in mimicry, mental state and overall quality of life according to the Spearman correlative coefficient. CONCLUSION: Orofacial rehabilitation therapy for patients with paresis after stroke has a significant influence on the adjustment of mimicry, mental functions and overall quality of life after 4 weeks of treatment.

Utilization of visual information and listener strategies in intelligibility impairment related to bilateral facial paresis.

This study investigated how intelligibility scores of a speaker with bilateral facial paresis differed in auditory-only and auditory-visual presentation modes. A speech sample was collected and movies were created in both auditory-only and auditory-visual modes. These movies were presented to listeners who were unfamiliar with the speaker (n=20) with 10 of the listeners randomly assigned to the auditory-only listening mode and 10 assigned to the auditory-visual mode. Listeners transcribed what they heard and also completed a scale to determine the strategies used to understand this speaker's utterances. Results of ANOVA revealed that intelligibility in the auditory-visual condition was significantly greater than intelligibility for the auditory-only condition. Listeners reported utilizing many strategies to transcribe the speaker's utterances and listeners in the auditory-visual mode utilized cognitive strategies significantly more than listeners in the auditory-only mode. Findings of this study highlight the importance of visual information provided to listeners, as well as the types of strategies that listeners may use or be taught to use in understanding speakers with dysarthria.

Positive effects of mime therapy on sequelae of facial paralysis: stiffness, lip mobility, and social and physical aspects of facial disability.

OBJECTIVE: Evaluation of the effect of mime therapy, a novel therapy combining mime and physiotherapy, for patients with longstanding (at least 9 months) sequelae of unilateral peripheral facial paralysis. STUDY DESIGN: Randomized clinical trial, with the treatment group receiving mime therapy and the control group forming a waiting list. SETTING: Physiotherapy outpatient department of two university medical centers. PATIENTS: There were 50 patients, 21 men and 29 women, with sequelae of facial paralysis and a mean House-Brackmann score of Grade IV. INTERVENTION: Mime therapy, including automassage, relaxation exercises, inhibition of synkinesis, coordination exercises, and emotional expression exercises. MAIN OUTCOME MEASURES: Stiffness of the face, lip mobility (both lip and pout length) and the physical and social index of the Facial Disability Index. RESULTS: Stiffness, lip mobility, and both aspects of the Facial Disability Index improved substantially because of mime therapy. CONCLUSIONS: On the basis of present evidence, mime therapy is a good treatment choice for patients with sequelae of facial paralysis.

Emotional experience and perception in the absence of facial feedback.

The facial feedback hypothesis suggests that facial expressions are either necessary or sufficient to produce emotional experience. Researchers have noted that the ideal test of the necessity aspect of this hypothesis would be an evaluation of emotional experience in a patient suffering from a bilateral facial paralysis; however, this condition is rare and no such report has been documented. We examined the role of facial expressions in the determination of emotion by studying a patient (F.P.) suffering from a bilateral facial paralysis. Despite her inability to convey emotions through facial expressions, F.P. reported normal emotional experience. When F.P. viewed emotionally evocative slides her reactions were not dampened relative to the normative sample. F.P. retained her ability to detect, discriminate, and image emotional expressions. These findings are not consistent with theories stating that feedback from an active face is necessary to experience emotion, or to process emotional facial expressions.

The illness known as "twisted mouth" among the Nêhinaw (Cree).

This paper is based on interviews with two individuals who talked about their experiences with a condition known as "twisted mouth." While the biomedical label of Bell's palsy is often applied to such cases, the appropriateness of this label is not explored here. Rather, the focus is on how Nêhinaw (Cree) cultural understandings frame the experience of and response to illness, even when biomedical practitioners were consulted. The interviews were carried out by the first author using the Nêhinaw language as much as possible. Subtle linguistic clues within the interviews point to the pervasiveness of Nêhinaw cultural understandings.

Contralaterally elicited electrical stimulation of paralyzed facial muscles.

Functional electrical stimulation is being explored in the extremities. A major obstacle is found in programming the firing sequence. In 1976, David Zealear proposed using the activity on the normal side in axial muscle pairs that normally function symmetrically to act as a template to control the stimulator. This method was demonstrated in laryngeal muscles in dogs, and is now demonstrated in the face with future applications being proposed. The facial nerve on one side was sectioned in a series of rabbits. Implanted electrodes received electrical potentials from selected muscles on the normal side. Bursts of electrical activity on the normal side during a blink or a twitch were used to trigger a muscle stimulator, which was routed to matching muscles on the paralyzed side. This technique restored symmetric function to the hemiparalyzed side. This technique restored symmetric function to the hemiparalyzed face.
