Mime therapy improves facial symmetry in people with long-term facial nerve paresis: a randomised controlled trial

Knowledge and Attitude Towards Bell's Palsy Rehabilitation Among Physical Therapists in Saudi Arabia: A Cross-Sectional Study

Background

Bell's Palsy (BP) is an acute lower motor nerve impairment of the facial nerve, causing sudden paralysis on one side of the face and significantly affecting the patient's quality of life. Physiotherapy is critical for rehabilitation after BP, aiding functional recovery. Various physical therapy interventions, such as dry needling, taping, and nerve mobilization, have proven effective in treating BP. However, different rehabilitation approaches and knowledge levels among therapists can result in varying treatment outcomes. Therefore, understanding rehabilitation specialists' knowledge and attitudes towards BP is essential for ensuring effective treatment. To date, no studies have examined the knowledge and attitudes of rehabilitation professionals in Saudi Arabia regarding BP.

Objective

This study aims to evaluate the knowledge and attitudes of physical therapists in Saudi Arabia regarding the rehabilitation of BP.

Methods

A cross-sectional observational study was conducted with 150 licensed physical therapists in Saudi Arabia, selected via convenience sampling. Participants completed an anonymous online survey covering demographics, knowledge of, and attitudes toward BP rehabilitation techniques. Descriptive and inferential statistics were used to analyze the data.

Results

The participants had a mean age of 33.13 ± 6.85 years, with 68.7% being female. Most held Bachelor's degrees (65.3%) and worked in general hospitals (72.7%). The average knowledge score was 8.99 ± 1.95, indicating moderate knowledge levels. Attitudes towards BP rehabilitation were positive, particularly regarding early intervention, emotional support, and coordination exercises. Significant differences in knowledge and attitudes were observed based on gender, experience, and practice location.

Conclusion

Physical therapists in Saudi Arabia demonstrate moderate knowledge and positive attitudes toward BP rehabilitation. Continued professional education and collaboration are recommended to improve clinical standards in treating BP.

Effect of modified facial paralysis rehabilitation nursing on patients with facial paralysis after vestibular schwannoma surgery

Background and objective

After vestibular schwannoma (VS) surgery, some patients exhibit different degrees of peripheral facial paralysis, which can seriously affect their quality of life. The recovery of facial nerve function after surgery typically takes a considerable amount of time; therefore, the recovery of facial nerve function depends mainly on the rehabilitation treatment and nursing after discharge. In the past, we implemented conventional paralysis rehabilitation nursing program for patients with facial paralysis due to VS surgery. However, several patients with facial paralysis have bad compliance and do not achieve ideal facial nerve function recovery. Therefore, this study aimed to investigate whether modified facial paralysis rehabilitation nursing improves the effectiveness of rehabilitation of facial paralysis after VS surgery by analysing the clinical data of patients.

Methods

We screened the patients with facial paralysis after VS surgery from December 2019 to May 2023. The patients were divided into the conventional and modified groups based on the different nursing programs (conventional vs. modified facial paralysis rehabilitation nursing program) to compare the differences in facial nerve function, quality of life of patients, and compliance of rehabilitation between the two groups.

Results

We analysed 128 patients with facial paralysis after VS surgery who met the inclusion and exclusion criteria; 65 and 63 patients in the conventional and modified group, respectively. The number of patients in the modified group with House-Brackmann grade changes >0 in facial nerve function was significantly higher than that in the conventional group 3 months after surgery (82.5 % vs 63.1 %, p = 0.01). Except for the lacrimal control score, the mean scores of the Chinese version of the FaCE scale were significantly higher in the modified group than those in the conventional group at 1 and 3 months postoperatively.

Conclusions

The modified facial paralysis rehabilitation nursing, i.e., integrated use of facial expressive muscle exercises and facial massage with video-assisted education, substantially improved the facial nerve function, quality of life, and compliance of rehabilitation nursing of patients with facial paralysis after VS surgery.

Approaches to the Management of Synkinesis: A Scoping Review

Postparalysis facial synkinesis (PPFS) can develop in any facial palsy and is associated with significant functional and psychosocial consequences for affected patients. While the prevention of synkinesis especially after Bell's palsy has been well examined, much less evidence exists regarding the management of patients with already established synkinesis. Therefore, the purpose of this review is to summarize the available literature and to provide an overview of the current therapeutic options for facial palsy patients with established synkinesis. A systematic literature review was undertaken, following the Preferred Reporting Items of Systematic Reviews and Meta-analyses 2020 guidelines. MEDLINE via PubMed and Cochrane Library were searched using the following strategy: ([facial palsy] OR [facial paralysis] OR [facial paresis]) AND (synkinesis) AND ([management] OR [guidelines] OR [treatment]). The initial search yielded 201 articles of which 36 original papers and 2 meta-analyses met the criteria for inclusion. Overall, the included articles provided original outcome data on 1,408 patients. Articles were divided into the following treatment categories: chemodenervation (12 studies, 536 patients), facial therapy (5 studies, 206 patients), surgical (10 studies, 389 patients), and combination therapy (9 studies, 278 patients). Results are analyzed and discussed accordingly. Significant heterogeneity in study population and design, lack of control groups, differences in postoperative follow-up, as well as the use of a variety of subjective and objective assessment tools to quantify synkinesis prevent direct comparison between treatment modalities. To date, there is no consensus on how PPFS is best treated. The lack of comparative studies and standardized outcome reporting hinder our understanding of this complex condition. Until higher quality scientific evidence is available, it remains a challenge best approached in an interdisciplinary team. An individualized multimodal therapeutic concept consisting of facial therapy, chemodenervation, and surgery should be tailored to meet the specific needs of the patient.

Consensus Among International Facial Therapy Experts for the Management of Adults with Unilateral Facial Palsy: A Two-Stage Nominal Group and Delphi Study

Background: Nonsurgical rehabilitation of unilateral peripheral facial palsy (FP) varies globally with controversy regarding best practice. Objective: To develop facial therapist consensus regarding what should be included or excluded in rehabilitation of adults with FP of any etiology. Three clinical presentations: flaccid, paretic and synkinetic, were separately considered. Methodology: A two-stage study was conducted: a nominal group technique (NGT) to develop a questionnaire plus Delphi study. Delphi participants were recruited worldwide, through an experience-based inclusion questionnaire. The final Delphi questionnaire included 166 items for each clinical presentation covering assessment, outcome measures, and interventions, for example, education, eye care, neuromuscular retraining, and electrical modalities. Inclusion/exclusion agreement was set at 80%, indicating participant consensus. Items reaching 70-79% were deemed "near-included/near-excluded." Results: Averaged across all presentations, 24.9% of the 166 items were included, (e.g., Sunnybrook Facial Grading System, patient education and neuromuscular retraining), 26.9% of the 166 items were excluded, (e.g., gross strengthening and electrical stimulation); 48.2% were neither included nor excluded. Conclusion: This study brings together the global community's expertise as a first step toward establishing best practice for specialist facial therapy. It is hoped this will guide clinical decision making, advance research, and optimize patient outcomes in this challenging field.

Task force of the Brazilian Society of Otology - evaluation and management of peripheral facial palsy

OBJECTIVE

To review key evidence-based recommendations for the diagnosis and treatment of peripheral facial palsy in children and adults.

METHODS

Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on peripheral facial palsy were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions.

RESULTS

The topics were divided into 2 main parts: (1) Evaluation and diagnosis of facial palsy: electrophysiologic tests, idiopathic facial palsy, Ramsay Hunt syndrome, traumatic peripheral facial palsy, recurrent peripheral facial palsy, facial nerve tumors, and peripheral facial palsy in children; and (2) Rehabilitation procedures: surgical decompression of the facial nerve, facial nerve grafting, surgical treatment of long-term peripheral facial palsy, and non-surgical rehabilitation of the facial nerve.

CONCLUSIONS

Peripheral facial palsy is a condition of diverse etiology. Treatment should be individualized according to the cause of facial nerve dysfunction, but the literature presents better evidence-based recommendations for systemic corticosteroid therapy.

Percutaneous Stylomastoid Foramen Pulsed Radiofrequency Combined with Steroid Injection for Treatment of Intractable Facial Paralysis After Herpes Zoster

INTRODUCTION

We investigated the safety and efficacy of percutaneous facial nerve pulsed radiofrequency combined with drug injection for treatment of intractable facial paralysis of herpes zoster. The authors provide a detailed description of percutaneous facial nerve pulsed radiofrequency combined with steroid injection for treatment of intractable facial paralysis after herpes zoster, and they examine its clinical efficacy. This is the first time in the literature to our knowledge that this procedure has been applied in facial paralysis after herpes zoster.

METHODS

A total of 43 patients with a history of facial paralysis after herpes zoster for > 1 month were enrolled in this retrospective study. The patients were subjected to percutaneous stylomastoid foramen pulsed radiofrequency of the facial nerve under computed tomography (CT) guidance combined with drug injection. The House-Brackmann grades and NRS (Numerical Rating Scale) data collection were performed at different time points (preoperatively, 1 day post-procedure, and 2, 4, and 12 weeks postoperatively). The occurrence of complications was also assessed.

RESULTS

The 43 participants successfully completed the CT-guided percutaneous stylomastoid foramen pulsed radiofrequency of the facial nerve combined with drug injection. Both approaches [posterior approach of the ear (7 cases) and anterior approach of the ear (36 cases)] were efficacious and safe. The House-Brackmann grades (I, II, III, IV, V, VI) were 4 (3-4), 2 (2-3), 1 (1-2), and 1 (0-2) at different operation times (T0, T1, T2, T3, T4); patients felt significant recovery at T1 after operation and had gradually recovered at each time point but had no significant recovery after T3. The NRS scores at different operation times were 2.690 ± 2.213, 0.700 ± 0.939, 0.580 ± 1.006, 0.440 ± 0.908, and 0.260 ± 0.759, respectively. Differences in NRS scores between T0 and T1/2/3/4 were significant while differences between T1 and T2/3/4 were not significant. Six patients developed mild numbness, nine patients exhibited muscle tension, while one patient exhibited facial stiffness. During surgery, there was no intravascular injection of drugs, no nerve injury was reported, and there was no local anesthetic poisoning or spinal anesthesia.

CONCLUSIONS

Percutaneous stylomastoid foramen pulsed radiofrequency combined with drug injection of the facial nerve for treatment of intractable facial paralysis after herpes zoster is a minimally invasive technique with high rates of success, safety, and effective outcomes. It is a potential therapeutic option for cases of facial paralysis of herpes zoster with a > 1 month history even for those with severe facial paralysis and whose treatment has failed after oral medication and physiotherapy.

Physical therapy for peripheral facial palsy: A systematic review and meta-analysis

OBJECTIVE

This study aimed to reveal the efficacy of physical therapy for patients with peripheral facial palsy.

METHODS

A literature search was conducted using PubMed, Ichushi-Web, and Cochrane Central Register of Controlled Trials. Published randomized controlled trials comparing the physical therapy versus placebo/non-treatment for peripheral facial palsy such as Bell's palsy, Ramsay Hunt syndrome, and traumatic facial palsy were included for meta-analysis. The primary outcome was non-recovery at the end of the follow-up. Non-recovery was defined according to the authors' definition. The secondary outcomes were the composite score of the Sunnybrook facial grading system and sequelae (presence of synkinesis or hemifacial spasm) at the end of the follow-up. Data was analyzed using Review Manager software and pooled risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI) were calculated.

RESULTS

Seven randomized controlled trials met the eligible criteria. The data on non-recovery from four studies was obtained and included 418 participants in the meta-analysis. Physical therapy might reduce non-recovery (RR = 0.51 [95% CI = 0.31-0.83], low quality). Pooling the data of composite score of the Sunnybrook facial grading system from three studies (166 participants) revealed that physical therapy might increase the composite scores (MD = 12.1 [95% CI = 3.11-21.0], low quality). Moreover, we obtained data on sequelae from two articles (179 participants). The evidence was very uncertain about the effect of physical therapy on reduction of sequelae (RR = 0.64 [95% CI = 0.07-5.95], very low quality).

CONCLUSION

The evidence suggested that physical therapy reduces non-recovery in patients with peripheral facial palsy and improves the composite score of the Sunnybrook facial grading system, whereas the efficacy of physical therapy in reducing sequelae remained uncertain. The included studies had high risk of bias, imprecision, or inconsistency; therefore, the certainty of evidence was low or very low. Further well-designed randomized controlled trials are needed to confirm its efficacy.

Efficacy of adding selective electrical muscle stimulation to usual physical therapy for Bell's palsy: immediate and six-month outcomes

Bell's palsy is the most common cause of facial paralysis, affecting one in every 60 people in their lifetime. Transcutaneously applied selective electrical muscle stimulation could potentially accelerate recovery from Bell's palsy but this intervention remains controversial. Studies have shown benefit, but concerns for lack of efficacy and potential for worsening synkinesis remain. We performed a prospective controlled trial comparing outcomes at initial recovery and six months later with selective electrical muscle stimulation and usual physical therapy versus usual physical therapy alone in adults with acute Bell's palsy. Outcomes were facial function assessed with the House Brackman and eFACE scales. Outcomes were evaluated at discharge and six months after discharge. Discharge occurred when participants were judged to be fully recovered by their treating therapist and supervisor. 38 adults participated in the study. Participants in the electrical stimulation group achieved maximal recovery twice as fast as the control group (2.5 weeks versus 5.2 weeks) with no significant differences in facial function or synkinesis between groups at any time point. This study is the first human trial of electrical stimulation in Bell's palsy to follow patients 6 months from recovery and supports that selective electrical muscle stimulation accelerates recovery and does not increase synkinesis.

Minimization of facial synkinesis

PURPOSE OF REVIEW

To summarize the treatment options available for the management of postparalytic facial synkinesis which include facial rehabilitation, chemodenervation, and a spectrum of surgical interventions.

RECENT FINDINGS

Facial rehabilitation and botulinum toxin chemodenervation represent the foundation of facial synkinesis management, with specific treatment paradigms directed by individual patient needs. Evolving surgical approaches range from isolated selective myectomies or neurectomies to combination approaches which may incorporate various types of nerve transfer with gracilis free muscle transplantation.

SUMMARY

Postparalytic facial synkinesis bears significant patient morbidity due to aesthetic and functional implications. Management strategies must balance patient goals with treatment risks and typically progress stepwise from the least to most invasive interventions. Emerging techniques reveal a convergence in approaches to facial reanimation and synkinesis mitigation.

Guided Self-rehabilitation Contract vs conventional therapy in chronic peripheral facial paresis: VISAGE, a multicenter randomized controlled trial

BACKGROUND

One year after persistent peripheral facial paresis (PFP), prescriptions of conventional rehabilitation are often downgraded into maintenance rehabilitation or discontinued, the patient entering what is seen as a chronic stage. This therapeutic choice is not consistent with current knowledge about behavior-induced plasticity, which is available all life long and may allow intense sensorimotor rehabilitation to remain effective. This prospective, randomized, multicenter single-blind study in subjects with chronic unilateral PFP evaluates changes in facial motor function with a Guided Self-rehabilitation Contract (GSC) vs. conventional therapy alone, carried out for six months.

METHODS

Eighty-two adult subjects with chronic unilateral PFP (> 1 year since facial nerve injury) will be included in four tertiary, maxillofacial surgery (2), otolaryngology (1) and rehabilitation (1) centers to be randomized into two rehabilitation groups. In the experimental group, the PM&R specialist will implement the GSC method, which for PFP involves intensive series of motor strengthening performed daily on three facial key muscle groups, i.e. Frontalis, Orbicularis oculi and Zygomatici. The GSC strategy involves: i) prescription of a daily self-rehabilitation program, ii) teaching of the techniques involved in the program, iii) encouragement and guidance of the patient over time, in particular by requesting a quantified diary of the work achieved to be returned by the patient at each visit. In the control group, participants will benefit from community-based conventional therapy only, according to their physician's prescription. The primary outcome measure is the composite score of Sunnybrook Facial Grading System. Secondary outcome measures include clinical and biomechanical facial motor function quantifications (Créteil Scale and 3D facial motion analysis through the Cara system), quality of life (Facial Clinimetric Evaluation and Short-Form 12), aesthetic considerations (FACE-Q scale) and mood representations (Hospital Anxiety and Depression scale). Participants will be evaluated every three months by a blinded investigator, in addition to four phone calls (D30/D60/D120/D150) to monitor compliance and tolerance to treatment.

DISCUSSION

This study will increase the level of knowledge on the effects of intense facial motor streng-          Facial paralysisthening prescribed through a GSC in patients with chronic peripheral facial paresis.

Botulinum toxin A treatment in facial palsy synkinesis: a systematic review and meta-analysis

BACKGROUND

Synkinesis is defined as involuntary movements accompanying by voluntary movements and can occur during the aftermath of peripheral facial palsy, causing functional, aesthetic and psychological problems in the patient. Botulinum toxin A (BTX-A) is frequently used as a safe and effective treatment; however, there is no standardized guideline for the use of BTX-A in synkinesis. The purpose of this article is to review and summarize studies about the BTX-A treatment of synkinesis in patients with a history of peripheral facial palsy; including given dosages, injection sites and time intervals between injections.

MATERIALS AND METHODS

A multi-database systematic literature search was performed in October 2020 using the following databases: Pubmed, Embase, Medline, and The Cochrane Library. Two authors rated the methodological quality of the included studies independently using the 'Newcastle-Ottawa Quality Assessment Scale' for non-randomised studies' (NOS).

RESULTS

Four-thousand-five-hundred-and-nineteen articles were found of which 34 studies met the inclusion criteria, in total comprising 1314 patients. Most studies were assessed to be of 'fair' to 'good' methodological quality. The Cohen's kappa (between author FJ and AS) was 0.78. Thirty-one studies investigated the reported dosage injected, 17 studies reported injection location and 17 studies investigated time intervals. A meta-analysis was performed for three studies comprising 106 patients, on the effects of BTX-A treatment on the Synkinesis Assessment Questionnaire (SAQ) scores. The mean difference was 11.599 (range 9.422-13.766), p < 0.01. However, due to inconsistent reporting of data of the included studies, no relationship with the dosage and location could be assessed.

CONCLUSIONS

Many treatment strategies for synkinesis exist, consisting of varying BTX-A brands, dosages, time intervals and different injection locations. Moreover, the individual complaints are very specific, which complicates creating a standardized chemodenervation treatment protocol. The BTX-A treatment of long-term synkinesis is very individual and further studies should focus on a patient-tailored treatment instead of trying to standardize treatment.

Effectiveness of facial palsy protocol among patient with mucormycosis following COVID-19: A case study

A 41-year-old male with a history of diabetes mellitus presented with right facial palsy post COVID-19 Associated Mucormycosis. A 4-week physiotherapeutic intervention; ice therapy, Mime therapy, Facial Soft Tissue Manipulation, and Facial Proprioceptive Neuromuscular Stimulation, showed improvement in the symptoms of patient and scores of House- Brackman Facial Grading Scale.

Development of an open-source and free facial rehabilitation website for severe bell's palsy: a within-subject study on user experience and patient's compliance with the MEPP-website

PURPOSE

An open source and free website called Mirror Effect Plus Protocol (MEPP)-website was developed with features to diminish cognitive load and support motor learning during facial exercises. Assessing patient's perceptions is crucial when developing rehabilitation tools because patients' willingness to use the tools strongly affect engagement in the rehabilitation process. This study compared clinicians' and patients' user experience with the MEPP-website versus a hobby-designed website.

MATERIALS AND METHODS

Ten patients with acute severe Bell's palsy and five clinicians were enrolled in a within-subject and crossover design. User experience was assessed with the Modular evaluation of Components of User Experience questionnaire. Wilcoxon-Signed-Rank test analysed user experience, and descriptive analyses explored the order effect. Therapeutic compliance was verified for the MEPP-website by an integrated feature. Clinicians' descriptive statistics and subjective observations were also reported.

RESULTS

Both patients and clinicians demonstrated a preference for the MEPP-website, whether they used it first or second. Despite this preference, compliance with the MEPP-website was reduced, although it tended to be better when used first.

CONCLUSIONS

MEPP- website during facial rehabilitation improved user experience. Better user experience likely optimizes how patients perform and facilitate their exercises. Factors affecting compliance with facial rehabilitation remain to be addressed.Implications for rehabilitationRecent data suggests that mirror effect therapy combined with drug therapy supports the recovery of severe Bell's Palsy.The specialized Mirror Effect Plus Protocol (MEPP)- website is a clinical computer-based tool developed to promote patients' motor learning and diminish cognitive load during mirror therapy.The MEPP-website increase clinicians' accessibility to a specialized facial rehabilitation tool for mirror therapy.Clinicians using the MEPP-website can also objectively and easily measure compliance to facial therapy with the MEPP-website.

Pathogenesis, diagnosis and therapy of facial synkinesis: A systematic review and clinical practice recommendations by the international head and neck scientific group

Introduction

Post-paralytic facial synkinesis after facial nerve injury produces functional disabilities and mimetic deficits, but also cosmetic and non-motor psychosocial impairments for the patients. These patients typically have a high and continuous high motivation for rehabilitation. The aim is to inform the affected patients and their therapeutic professionals (otorhinolaryngologist - head and neck surgeons; oral-maxillofacial surgeons, plastic and reconstructive surgeons, neurosurgeons, neurologists, and mime therapists be it speech and language therapy- or physiotherapy-based) and to provide practical recommendations for diagnostics and a stepwise systematic treatment approach of facial synkinesis.

Methods

In the first phase, a systematic literature search on the topic in PubMed and ScienceDirect starting in 2008 resulted in 132 articles. These were the basis for the review and a comprehensive series of consensus statements on the most important diagnostic tests and treatment options. In the second phase, one consensus article circulated among the membership of the International Head and Neck Scientific Group until a final agreement was reached for all recommendations.

Results

Diagnostics should include a standardized assessment of the degree of synkinesis using validated clinician-graded instruments and synkinesis-specific patient-reported outcome measures. Treatments for facial synkinesis include facial training mainly based on facial biofeedback retraining, chemodenervation with botulinum toxin, selective neurectomy, myectomy, and any combination treatment of these options.

Conclusion

A basic understanding of the pathomechanisms of synkinesis is essential to understand the treatment strategies. A standardized assessment of the synkinetic symptoms and the individual synkinesis pattern is needed. The first-line treatment is facial training, followed by botulinum toxin. Surgery is reserved for individual cases with unsatisfactory first-line treatment.

Physical therapy for facial nerve paralysis (Bell's palsy): An updated and extended systematic review of the evidence for facial exercise therapy

OBJECTIVE

To conduct a systematic review of the effectiveness of facial exercise therapy for facial palsy patients, updating an earlier broader Cochrane review; and to provide evidence to inform the development of telerehabilitation for these patients.

DATA SOURCES

MEDLINE, EMBASE, CINAHL, Cochrane Library, PEDro and AMED for relevant studies published between 01 January 2011 and 30 September 2020.

METHODS

Predetermined inclusion/exclusion criteria were utilised to shortlist abstracts. Two reviewers independently appraised articles, systematically extracted data and assessed the quality of individual studies and reviews (using GRADE and AMSTAR-2, respectively). Thematic analysis used for evidence synthesis; no quantitative meta-analysis conducted. The review was registered with PROSPERO (CRD42017073067).

RESULTS

Seven new randomised controlled trials, nine observational studies, and three quasi-experimental or pilot studies were identified (n  =  854 participants). 75% utilised validated measures to record changes in facial function and/or patient-rated outcomes. High-quality trials (4/7) all reported positive impacts; as did observational studies rated as high/moderate quality (3/9). The benefit of therapy at different time points post-onset and for cases of varying clinical severity is discussed. Differences in study design prevented data pooling to strengthen estimates of therapy effects. Six new review articles identified were all rated critically low quality.

CONCLUSION

The findings of this targeted review reinforce those of the earlier more general Cochrane review. New research studies strengthen previous conclusions about the benefits of facial exercise therapy early in recovery and add to evidence of the value in chronic cases. Further standardisation of study design/outcome measures and evaluation of cost-effectiveness are recommended.

The "Mirror Effect Plus Protocol" for acute Bell's palsy: A randomized controlled trial with 1-year follow-up

OBJECTIVE

To study the effects of the "Mirror Effect Plus Protocol" (MEPP) on global facial function in acute and severe Bell's Palsy.

DESIGN

Single blind and randomized controlled trial to compare the effects of basic counseling (control group) versus MEPP (experimental group) over one year.

SETTING

Outpatient clinic following referrals from Emergency or Otorhinolaryngology Departments.

SUBJECTS

40 patients (n = 20 per group) with moderately severe to total palsy who received standard medication were recruited within 14 days of onset. Baseline characteristics were comparable between the groups.

INTERVENTIONS

The experimental group received the MEPP program (motor imagery + manipulations + facial mirror therapy) while the control group received basic counseling. Both groups met the clinician monthly until 6 months and at one-year post-onset for assessments.

OUTCOME MEASURES

Facial symmetry, synkinesis, and quality of life were measured using standardized scales. Perceived speech intelligibility was rated before and after therapy by naïve judges.

RESULTS

Descriptive statistics demonstrated improvements in favor of the MEPP for each measured variable. Significant differences were found for one facial symmetry score (House-Brackmann 2.0 mean (SD) = 7.40 (3.15) for controls versus 5.1 (1.44) for MEPP), for synkinesis measures (p = 0.008) and for quality-of-life ratings (mean (SD) score = 83.17% (17.383) for controls versus 98.36% (3.608) for MEPP (p = 0.002)). No group difference was found for perceived speech intelligibility.

CONCLUSION

The MEPP demonstrates promising long-term results when started during the acute phase of moderately severe to total Bell's Palsy.

Is There a Difference in Facial Emotion Recognition after Stroke with vs. without Central Facial Paresis?

The Facial Feedback Hypothesis (FFH) states that facial emotion recognition is based on the imitation of facial emotional expressions and the processing of physiological feedback. In the light of limited and contradictory evidence, this hypothesis is still being debated. Therefore, in the present study, emotion recognition was tested in patients with central facial paresis after stroke. Performance in facial vs. auditory emotion recognition was assessed in patients with vs. without facial paresis. The accuracy of objective facial emotion recognition was significantly lower in patients with vs. without facial paresis and also in comparison to healthy controls. Moreover, for patients with facial paresis, the accuracy measure for facial emotion recognition was significantly worse than that for auditory emotion recognition. Finally, in patients with facial paresis, the subjective judgements of their own facial emotion recognition abilities differed strongly from their objective performances. This pattern of results demonstrates a specific deficit in facial emotion recognition in central facial paresis and thus provides support for the FFH and points out certain effects of stroke.

Including Arts in Rehabilitation Enhances Outcomes in the Psychomotor, Cognitive, and Affective Domains: A Scoping Review

OBJECTIVE

The purpose of this scoping review was to analyze the published literature regarding the use of art in the context of rehabilitation for consideration in physical therapy.

METHODS

The CINAHL, PsycArticles, APA PsycInfo, Art Index, Music Index, Cochrane Reviews, and PubMed electronic databases were accessed. Inclusion and exclusion criteria were established and utilized to determine study eligibility. Study details were extracted from each article by researchers using a systematic format. Summation of journal type, participants, dosing and type of intervention, setting and interventionist, outcome domains, and study results were included.

RESULTS

Out of 1452 studies, 76 were included for extraction. Of these studies, most had outcome measures aligned with the psychomotor and affective domains of learning (n = 66). Very few studies had outcome measures with psychomotor and cognitive domains (n = 2) or psychomotor, affective, and cognitive outcome measures (n = 8). Regarding the arts used, music, dance, or both were used in 77 instances. Fewer studies reported using creative arts therapy, singing, theater, writing, and rhythm (n = 17). Of the 76 studies analyzed, 74 reported a within-group treatment effect.

CONCLUSION

The arts effectively enhance physical therapist practice; therefore, it is recommended that physical therapists continue to seek collaboration with art professionals and explore the use of arts in practice.

IMPACT

Findings demonstrate that combining the arts with physical therapist practice amplifies not only psychomotor but affective and cognitive outcomes as well. The arts have applicability across broad populations (eg, chronic pain, neurologic dysfunction, respiratory conditions). This study supports that physical therapist education and practice should embrace the arts as a collaborative modality to promote enhanced psychomotor, affective, and cognitive outcomes.

3D Printed Motor-Sensory Module Prototype for Facial Rehabilitation

This work demonstrates the first 3D printed wearable motor-sensory module prototype designed for facial rehabilitation, focusing on facial paralysis. The novelty of the work lies in the fast fabrication of the first fully soft working prototype, including feedback control, with a focus on the methodology for individual customization. Facial paralysis results from a variety of conditions, and more wearable and modular technologies are needed to address the complexity of facial movement rehabilitation. Smiling muscles are especially important for both expression and eating, and so this work focuses on this motion as an example of how the module can be applied to mimic and support needed muscle movement. A generalized actuator-sensor pair with a feedback control system is created to translate signals from smiling on the healthy side of the face (notably temporal and zygomatic branch) to actuation on the paralyzed side of the face for augmented physiotherapy. Fabric and a sensor fluid are integrated during the silicone printing process to create a multicomponent wearable that is ready to use with minimal postprocessing. The actuators' force and vertical contraction results under a 0.98 and 1.96 N load meet the 1-7 N requirements needed for smiling. It is a challenge to measure soft surface-based force and contraction ratio consistently; therefore, a novel modular surface is designed to simulate the interaction of skin and bone using 3D printed hard plastic (bone) and a silicone sheet (skin). The actuator is tested on top of four different repeatable and standardized surface morphologies, and results reveal that the actuator force application will vary based on topography and hardness of the facial surface. Demonstration of the complete system on the face while collecting sensor and pressure data serves as a proof-of-concept and motivates potential applications in rapid customization of highly specialized soft wearable orthotics, prosthetics, and rehabilitation devices. This unique actuator-sensor combination can have additional applications for wearables due to the (1) customizability, (2) closed-loop control, and (3) unique "grounding" test platform.

Therapists' perceptions and attitudes in facial palsy rehabilitation therapy: A mixed methods study

Background: Facial palsy rehabilitation therapy plays an essential role in treating facial palsy.Purpose: This study aimed to gain insight into therapists' perceptions and attitudes toward facial palsy rehabilitation therapy and to examine whether therapists could be categorized into distinct groups based on these attitudes and perceptions.Methods: Thirteen semi-structured, in-depth interviews were conducted in a purposive sample of therapists. Interviews were analyzed using thematic analysis. Next, a questionnaire containing questions about therapists' characteristics and perceptions and attitudes toward facial palsy rehabilitation therapy was sent to all facial palsy rehabilitation therapists in the Netherlands and Flanders (n = 292). Latent class analysis (LCA) was performed to identify and analyze distinct groups of therapists.Results: Seven themes were derived from the interviews: treatment goals, therapy content, indications, measurement instruments, factors influencing success, emotional support, and cooperation with colleagues. The questionnaire was filled out by 127 therapists. A 2-group structure consisting of a positive class and a negative class was found to fit the questionnaire data best. No distinction could be made regarding therapists' characteristics.Conclusion: Considerable variation in stated treatment practices was present among therapists. Therapists could be classified into 2 groups. This study raises several hypotheses that require further study.

Combining an end to side nerve to masseter transfer with cross face nerve graft for functional upgrade in partial facial paralysis-an observational cohort study

BACKGROUND

Results of a single stage technique combining cross facial nerve graft(s) (CFNG) with an ipsilateral end to side nerve to masseter transfer (NTM) in incomplete facial paralysis are assessed in a retrospective cohort study. The hypothesis is that the technique can safely improve the quality of smile in these patients. End to side coaptations for the recipient facial nerve minimise the risk of iatrogenic function loss, contrasting with the end to end neurorrhaphies used in conventional babysitting procedures.

METHODS

A series of 27 patients was studied through case note review and standardised assessments. Surgical technique involves extensive exposure of the facial nerve and the NTM on the affected side and access is by bilateral preauricular incisions. End to end coaptations are made to the facial nerve on the donor side and on the recipient a standard CFNG is combined with an end to side NTM coaptation. Follow up was a minimum of 9 months from surgery.

RESULTS

Overall improvement in the Sunnybrook scale averaged 33, from a pre-operative score of 40 (p < 0.05). Average upgrade of 4.7 mm of increased movement at the modiolus was achieved (p < 0.05), 43% improvement compared to the normal side. An improved resting symmetry of 3.8 mm was achieved in relevant cases. Where eye closure was strengthened the average improvement was 5 mm of increased lid closure. The smile achieved was spontaneous in 22 of 27 cases.

CONCLUSION

The study confirms the hypothesis that CFNG with NTM transfer offers a physiological upgrade of facial movement in partial facial paralysis, applicable in both early and longstanding cases.

Physical Therapy for Iatrogenic Facial Paralysis: A Systematic Review

Importance

Facial paralysis (FP) after surgery has substantial functional, emotional, and financial consequences. Most iatrogenic FP is managed by watchful waiting, with the expectation of facial function recovery. A potential treatment is physical therapy (PT).

Objective

To investigate whether noninvasive PT compared with no PT or other intervention improves facial nerve outcomes in adults with iatrogenic FP.

Evidence Review

Patients with noniatrogenic FP, facial reanimation surgery, and invasive adjunctive treatments (acupuncture or botulinum toxin injection) were excluded. A systematic review was conducted for records discussing iatrogenic FP and PT; a search for these records was performed using Ovid MEDLINE (1946-2019), Embase (1947-2019), Scopus (1823-2019), Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry Platform (2004-2019), and ClinicalTrials.gov (1997-2019). The references of all the included articles were also assessed for eligible studies. All human participant, English-language study designs with at least 2 cases were included. Quality assessment was performed using the Methodological Index for Non-randomized Studies (MINORS) and the revised Cochrane Risk of Bias 2 (RoB 2) tool for randomized controlled trials. All search strategies were completed on May 16, 2019, and again on October 1, 2019.

Findings

Fifteen studies (7 of which were retrospective cohort studies) and 313 patients with iatrogenic FP were included in the systematic review. Most iatrogenic FP (166 patients [53%]) was associated with parotidectomy; traditional PT (ie, facial massage) was the most common intervention (196 patients [63%]). The use of various facial grading systems and inconsistent reporting of outcomes prevented direct comparison of PT types.

Conclusions and Relevance

Because of heterogeneity in reported outcomes of facial nerve recovery, definitive conclusions were unable to be made regarding the association between PT and outcomes of iatrogenic FP. Physical therapy probably has benefit and is associated with no harm in patients with iatrogenic FP.

Raising the Digital Profile of Facial Palsy: National Surveys of Patients' and Clinicians' Experiences of Changing UK Treatment Pathways and Views on the Future Role of Digital Technology

BACKGROUND

Facial nerve palsy leaves people unable to move muscles on the affected side of their face. Challenges exist in patients accessing facial neuromuscular retraining (NMR), a therapy used to strengthen muscle and improve nerve function. Access to therapy could potentially be improved through the use of digital technology. However, there is limited research available on patients' and clinicians' views about the potential benefits of such telerehabilitation based on their lived experiences of treatment pathways.

OBJECTIVE

This study aims to gather information about facial palsy treatment pathways in the United Kingdom, barriers to accessing NMR, factors influencing patient adherence, measures used to monitor recovery, and the potential value of emerging wearable digital technology.

METHODS

Separate surveys of patients with facial palsy and facial therapy specialists were conducted. Questionnaires explored treatment pathways and views on telerehabilitation, were co-designed with users, and followed a similar format to enable cross-referencing of responses. A follow-up survey of national specialists investigated methods used to monitor recovery in greater detail. Analysis of quantitative data was conducted allowing for data distribution. Open-text responses were analyzed using thematic content analysis.

RESULTS

A total of 216 patients with facial palsy and 25 specialist therapists completed the national surveys. Significant variations were observed in individual treatment pathways. Patients reported an average of 3.27 (SD 1.60) different treatments provided by various specialists, but multidisciplinary team reviews were rare. For patients diagnosed most recently, there was evidence of more rapid initial prescribing of corticosteroids (prednisolone) and earlier referral for NMR therapy. Barriers to NMR referral included difficulties accessing funding, shortage of specialist therapists, and limited awareness of NMR among general practitioners. Patients traveled long distances to reach an NMR specialist center; 9% (8/93) of adults reported traveling ≥115 miles. The thematic content analysis demonstrates positive attitudes to the introduction of digital technology, with similar incentives and barriers identified by both patients and clinicians. The follow-up survey of 28 specialists uncovered variations in the measures currently used to monitor recovery and no agreed definitions of a clinically significant change for any of these. The main barriers to NMR adherence identified by patients and therapists could all be addressed by using suitable real-time digital technology.

CONCLUSIONS

The study findings provide valuable information on facial palsy treatment pathways and views on the future introduction of digital technology. Possible ways in which emerging sensor-based digital technology can improve rehabilitation and provide more rigorous evidence on effectiveness are described. It is suggested that one legacy of the COVID-19 pandemic will be lower organizational barriers to this introduction of digital technology to assist NMR delivery, especially if cost-effectiveness can be demonstrated.

Trends in the Treatment of Bell's Palsy

The aim of the study is to: (1) evaluate national trends in care of facial paralysis, namely Bell's palsy, patients to identify the types of treatments patients are receiving and treatment gaps and (2) identify if newer, more complex surgical therapies published in the literature are being employed. Data were collected from the MarketScan Commercial Claims and Encounters Database by Truven Health. From the database, all inpatient and outpatient claims with International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes for facial paralysis/dysfunction between 2005 and 2013 were extracted. Trends in medical and surgical management were evaluated specifically cataloging the use of steroids, antivirals, botulinum toxin, surgical and rehabilitation service current procedural terminology codes. A total of 42,866 of patients with a formal diagnosis of Bell's palsy were identified with 39,292 (92%) adults and 3,754 (8%) children (< 18 years old), respectively. Steroids were provided to 50.1% of children and 59.8% of adults and antivirals were prescribed to 26.2 and 39.4% of the children and adults, respectively. Within the first 2 years after diagnosis, 0.5% of children and 0.9% of adults received surgery, 0.1% of children and 0.8% of adults received botulinum toxin treatments, and 10.9% of children and 21.5% of adults received rehabilitation services. Despite the limitations of a claims database study, results showing trends in care of facial paralysis are still nonsurgical with many patients receiving no treatment at all. Although limited literature has shown an increase in the use of pharmacotherapy as well as techniques including physiotherapy, chemodenervation, and various surgical therapies, these interventions may be underutilized.

Mirror Book Therapy for the treatment of Idiopathic Facial Palsy

OBJECTIVE

To determine the utility of treating facial palsy with mirror book therapy in conjunction with facial physical rehabilitation.

METHODS

We randomly selected and reviewed the charts of 25 patients with idiopathic facial palsy. 10 of these patients received facial physical rehabilitation including manual therapy and postural exercises. 15 of these patients received mirror book therapy in conjunction with standard facial rehabilitation. Before and after treatment, patients in both groups were rated using the Facial Grading System (FGS) score, the Facial Disability Index--Physical (FDIP) score, and the Facial Disability Index--Social (FDIS) score. Differences in response to therapy were analyzed.

RESULTS

Patients in the facial physical rehabilitation group without mirror book therapy group showed on average a 20.8% increase in the FGS score, a 19% increase in the FDIP score, and a 14.6% increase in the FDIS score. Patients in the mirror book therapy group showed an average of 24.9% increase in the Facial Grading System (FGS) score, a 21.6% increase in the Facial Disability Index--Physical (FDIP) score, and a 24.5% increase in the Facial Disability Index--Social (FDIS) score.

CONCLUSION

The addition of mirror book therapy to standard facial rehabilitation treatments does significantly improve outcomes in the treatment of idiopathic facial palsy.

Facial taping as biofeedback to improve the outcomes of physical rehab in Bell's palsy: preliminary results of a randomized case-control study

PURPOSE

This study aimed to investigate the efficacy of taping in association with Kabat rehabilitation to ameliorate the outcomes of Bell's palsy.

METHODS

This case-control study was conducted on hospital-outbound patients. 20 patients over 18 years affected from Bell's palsy were recruited at the onset of the disease (< 5 days). Patients were simply randomized into two groups. Patients in group A underwent exclusively Kabat rehabilitation, while patients in group B were treated by combining facial taping and Kabat. Facial palsy severity was evaluated with ADS assessment at baseline (T0), 1 week (T1), 1 month (T2) and 3 months (T3) after treatment. One-way ANOVA was used to compare ADS scores variance between groups to evaluate differences between the two treatments.

RESULTS

Both groups presented statistically significant differences comparing the baseline with the other observational points (within analysis) (p < 0.0001). Patients in group B showed a statistically significant improvement compared to group A (between analyses) (p < 0.0001), especially at T2 (p < 0.01).

CONCLUSIONS

Facial taping combined with Kabat rehabilitation allowed to reduce the time of recovery and improved the outcomes of Bell's palsy.

Combination of in-situ collagen injection and rehabilitative treatment in long-lasting facial nerve palsy: a pilot randomized controlled trial

BACKGROUND

Many rehabilitative attempts have been made to prevent or reduce residual deficits in patients with established and long-term facial palsy (FP). In many clinical settings in-situ injection of collagen-based medical devices have been demonstrated to provide nutritional support for tissues.

AIM

To test the effectiveness of a collagen-based treatment for patients complaining of long standing FP, who are following a proprioceptive neuromuscular facilitation protocol (Kabat method) (group A), compared to a FP group only undergoing the Kabat method (group B).

DESIGN

Randomised controlled trial.

SETTING

Tertiary referral outpatient center and University Hospital.

POPULATION

Forty-one patients with a medical diagnosis of long-term unilateral peripheral FP.

METHODS

Twenty-one Group A patients were compared, after randomization, to nineteen matched group B patients after 8 weeks of treatment. The outcomes were electromyographic findings, validated questionnaires (Facial Disability Index, FDI and General health-related quality of life assessment, QOL) and clinical grading (House-Brackmann, HB, and synkinesis grading scale). A correlation analysis was performed between pre-/post-treatment differences (Δ) in outcome and clinical-demographic measures.

RESULTS

A significant within-subjects improvement, both in electrophysiological and questionnaire scores, was found in both groups. When compared with group B, group A patients exhibited a significant reduction of post-treatment polyphasic potentials of voluntary activity of orbicularis oculi (P=0.017) and oris (P=0.015) and a significant increase in post-treatment duration of voluntary activity of orbicularis oris (P=0.018). Group A subjects demonstrated a significant improvement in questionnaire subscales regarding overall disease perception. Although positive correlations between the ∆FDI and ∆percentage of polyphasic potentials of voluntary activity were found in both groups, negative correlations in group A were found between disease duration and ∆duration of voluntary activity of orbicularis oculi and oris.

CONCLUSIONS

The combination of physical rehabilitative procedures with in-situ collagen injections, possibly acting in redirecting the phenomena of reinnervation/reorganization, demonstrated encouraging results in patients affected by long term FP.

CLNICAL REHABILITATION IMPACT

In-situ collagen injection could be a safe option enlarging the 'window of opportunity' to improve the voluntary muscle contraction pattern and general and specific disability referred by patients affected by long standing FP.

Developmental unilateral facial palsy in a newborn: six cases and literature review

Unilateral facial palsy in a newborn is rarely caused by a developmental defect. It occurs either isolated or in the context of a syndrome. This article describes a multidisciplinary approach towards unilateral, isolated congenital facial palsy along with a literature review. We report six patients, three boys and three girls, who presented with a unilateral facial palsy at birth. Clinical assessment was performed by an ear-nose-throat (ENT) surgeon, a pediatric neurologist, and an ophthalmologist. Magnetic resonance imaging (MRI) of the posterior fossa and computerized tomography (CT) of the temporal bone were requested to exclude structural anomalies of the facial nerve. Imaging revealed the underlying cause in five patients out of six (80%), showing an ipsilateral facial nerve aplasia or hypoplasia. These findings point towards an underlying developmental defect and underscore the importance of MRI in the diagnostic work-up. Surgical and non-surgical therapies were discussed with the parents.Conclusion: Congenital unilateral facial palsy caused by a developmental defect outside the context of a syndrome is rare. A multidisciplinary approach is recommended to differentiate between various causes and to initiate timely treatment.What is Known:• Congenital facial palsy is mostly caused by environmental/external fcators.• However in rare cases it can be developmental defect.What is New:• This paper describes 6 cases of isolated congenital facial palsy related to a developmental defect and presents the largest case series in the literature caused by aplasia/hypoplasia of the facial nerve.• MRI and CT-imaging allow for an assessment of the facial nerve at the root entry zone of the brainstem and along its course through the middle ear or the face. Moreover, they proved to be helpful in differentiating between several causes of congenital facial palsy.

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.

Facial Rehabilitation: Evaluation and Treatment Strategies for the Patient with Facial Palsy

This article describes the most widely used clinician-graded and patient-reported outcome measures, and describes facial rehabilitation strategies for acute and chronic facial palsy, and rehabilitation following dynamic facial reanimation surgery. The multimodality rehabilitation of the facial palsy patient is determined by the extent of facial nerve injury, specific functional deficits, the presence of synkinesis, and the patient's individual goals. Appropriate intervention, including patient education, soft tissue mobilization, neuromuscular reeducation, and chemodenervation, decreases facial tension and improves facial muscle motor control, physical function, facial expression, and quality of life.

Paradoxical Frontalis Activation: An Underrecognized Consequence of Facial Palsy

BACKGROUND

Aberrant reinnervation and synkinesis are common and debilitating after facial palsy. Paradoxical frontalis activation can antagonize eye closure and increase the risk of corneal damage. If recognized, judicious botulinum toxin injection to the affected side may reduce this risk.

METHODS

One hundred consecutive patients with synkinesis were identified from a prospective database. Routine facial view photographs were converted to a standardized scale using iris diameter. The vertical distance from the midpoint of the midcanthal line to the inferior border of the eyebrow was measured bilaterally. A value of p < 0.05 was considered significant.

RESULTS

Eighty-two patients were included, with a median age of 44 years (interquartile range, 33 to 59 years); 59 of the patients were women. The commonest cause was idiopathic (n = 55). The median time since onset of palsy was 13 months (interquartile range, 6.5 to 27 months). There was less midpoint of the midcanthal line to the inferior border of the eyebrow excursion on the synkinetic side of the face (p < 0.001). Twenty-two patients (27 percent) displayed paradoxical frontalis movement on the affected side of their face, with increased midpoint of the midcanthal line to the inferior border of the eyebrow distance (eyebrow raise) when attempting eye closure compared with eyebrow raise (n = 19), and tight eye closure compared with gentle eye closure (n = 3).

CONCLUSIONS

This study highlights the phenomenon of paradoxical frontalis activation during eye closure. This is often underrecognized and may contribute to lagophthalmos. The authors found it to be present in 27 percent of patients with moderate or severe synkinesis. Further dynamic studies are required to understand the relationship among frontalis activity, eye closure, and the effects of its inhibition.

Role of Kabat rehabilitation in facial nerve palsy: a randomised study on severe cases of Bell's palsy

The treatment of Bell's palsy (BP), based on steroids and/or antiviral drugs, may still leave a certain percentage of affected subjects with disfiguring sequelae due to incomplete recovery. The different procedures of physical rehabilitation have not been demonstrated to play a favourable role in this disorder. The aim of the present study was to compare functional outcomes in severe cases of Bell's palsy when treated by steroids alone or by steroids accompanied by Kabat physical rehabilitation. This prospective study included 94 subjects who showed sudden facial nerve (FN) palsy with House-Brackmann grade IV or V and who were divided into two groups on the basis of the therapeutic approach: one group (a) was treated by steroids, and the other (b) received steroids in combination with physical rehabilitation. Medical treatment consisted in administration of steroids at a dosage of 60 mg per day for 15 days; physical rehabilitative treatment consisted in proprioceptive neuromuscular facilitation according to Kabat, and was administered to one of the two groups of subjects. Recovery rate, degree of recovery and time for recovery were compared between the two groups using the Mann-Whitney and univariate logistic regression statistical tests (Ward test). Kabat patients (group b) had about 20 times the odds of improving by three HB grades or more (OR = 17.73, 95% CI = 5.72 to 54.98, p < 0.001) than patients who did not receive physical treatment (group a). The mean speed of recovery in group b was the half of that recorded for group a (non-Kabat subjects). No difference was observed in the incidence of synkineses between the two groups. Steroid treatment appears to provide better and faster recovery in severe cases (HB IV and V) of BP when complemented with Kabat physical rehabilitation.

Description of interventions is under-reported in physical therapy clinical trials

•

A clear definition and description of the interventions in randomized controlled trials are pre-requisites for implementation in clinical practice.

•

There is a trend among investigators to describe control group interventions poorly compared to the experimental group.

•

The readers would not be able to apply the findings of the trial to their clinical practice if the interventions are poorly described.

Background

Amongst several barriers to the application of quality clinical evidence and clinical guidelines into routine daily practice, poor description of interventions reported in clinical trials has received less attention. Although some studies have investigated the completeness of descriptions of non-pharmacological interventions in randomized trials, studies that exclusively analyzed physical therapy interventions reported in published trials are scarce.

Objectives

To evaluate the quality of descriptions of interventions in both experimental and control groups in randomized controlled trials published in four core physical therapy journals.

Methods

We included all randomized controlled trials published from the Physical Therapy Journal, Journal of Physiotherapy, Clinical Rehabilitation, and Archives of Physical Medicine and Rehabilitation between June 2012 and December 2013. Each randomized controlled trial (RCT) was analyzed and coded for description of interventions using the checklist developed by Schroter et al.

Results

Out of 100 RCTs selected, only 35 RCTs (35%) fully described the interventions in both the intervention and control groups. Control group interventions were poorly described in the remaining RCTs (65%).

Conclusions

Interventions, especially in the control group, are poorly described in the clinical trials published in leading physical therapy journals. A complete description of the intervention in a published report is crucial for physical therapists to be able to use the intervention in clinical practice.

Mime therapy for Ramsay Hunt syndrome: A case study

Background/Aim:

There are limited physiotherapy interventions and lack of significant outcome for Ramsay Hunt syndrome. This case report is the first to our knowledge that uses mime therapy as physiotherapy treatment for Ramsay Hunt syndrome.

Method:

A 53-year-old male patient received mime therapy along with electrical stimulation at two and half months post-diagnosis. The patient received electrical stimulation at the first week intervention as 30 minutes per session for 5 days a week and was discontinued at the third week intervention because the patient could not continue with facial muscle stimulation at home. Mime therapy was given three times a week for 13 weeks, with a total of 24 visits spread over 3 months.

Findings:

Facial symmetry was measured using the Sunnybrook Facial Grading System and severity of paresis was measured using the House-Brackmann scale throughout the course of treatment. House-Brackmann grades improved from grade V to grade II. Facial symmetry and synkinesis also improved. The facial disability index also showed improvement in both the physical function and social/wellbeing subscale components (Initial scores: physical subscale = 35/100; social/wellbeing subscale = 55/100. The final scores: physical subscale = 75/100; social/wellbeing subscale = 85/100).

Conclusions:

Overall, mime therapy was effective and benefits are stable for the short term. Therefore, mime therapy can be a good treatment choice for patients with Ramsay Hunt syndrome. Further research should include randomised controlled trials with a large sample size to prove its long-term effects.

Acupuncture for the sequelae of Bell's palsy: a randomized controlled trial

BACKGROUND

Incomplete recovery from facial palsy results in social and physical disabilities, and the medical options for the sequelae of Bell's palsy are limited. Acupuncture is widely used for Bell's palsy patients in East Asia, but its efficacy is unclear.

METHODS

We performed a randomized controlled trial including participants with the sequelae of Bell's palsy with the following two parallel arms: an acupuncture group (n = 26) and a waiting list group (n = 13). The acupuncture group received acupuncture treatments for 8 weeks, whereas the waiting list group did not receive acupuncture treatments during the 8-week period after randomization. The primary outcome measure was change in the Facial Disability Index (FDI) social and well-being subscale at week 8. We also analyzed changes in the FDI physical function subscale, the House-Brackmann score, the Sunnybrook Facial Nerve Grading system, lip mobility and stiffness at 5 and 8 weeks after randomization. An intention-to-treat analysis was applied.

RESULTS

The acupuncture group exhibited greater improvements in the FDI social score (mean difference, 23.54; 95% confidence interval, 12.99 to 34.08) and better results on the FDI physical function subscale (mean difference, 21.54; 95% confidence interval, 7.62 to 35.46), Sunnybrook Facial Nerve Grading score (mean difference, 14.77; 95% confidence interval, 5.05 to 24.49), and stiffness scale (mean difference, -1.58; 95% confidence interval,-2.26 to -0.89) compared with the waiting list group after 8 weeks. No severe adverse event occurred in either group.

CONCLUSION

Compared with the waiting list group, acupuncture had better therapeutic effects on the social and physical aspects of sequelae of Bell's palsy.

Advances in diagnosis and non-surgical treatment of Bell's palsy

Bell's palsy is a commonly seen cranial nerve disease and can result in compromised facial appearance and functions. Its etiology, prognosis and treatment are still being debated. This paper is a review of recent development in the understanding of etiology, diagnosis and non-surgical treatment of Bell's palsy.
