Modern Possibilities for Reconstruction of Nerves of the Head and Neck

The main etiological factors of nerve damage to the head and neck include injuries, oncological diseases, iatrogenic injuries during surgical interventions. An important task of treatment is to restore the lost function of the nervous head and neck, the functions of which certainly determine the quality of life of the patient. The article presents modern methods of nerve reconstruction of the head and neck. The methods of reconstructive surgery of the facial, trigeminal, inferior alveolar, lingual, recurrent laryngeal nerves are described. This article also describes the types of rehabilitation after reconstructive operations on the nerves of the head and neck using pharmacological and non-pharmacological treatment methods such as botulinum therapy, neuromuscular retraining, taping, post-isometric relaxation, acupuncture, phonophoresis, gymnastics.

Combining early lower eyelid surgery with neuromuscular retraining for synkinesis prevention after facial palsy: the role of the eye in aberrant facial nerve regeneration.

Facial synkinesis (FS) is a distressing sequela of facial palsy (FP) characterized by involuntary, simultaneous movements of facial muscles occurring during voluntary facial expressions. Treatment of synkinesis is challenging, and preventive methods are needed. This study evaluated the efficacy of physical facial nerve rehabilitation (PFNR) therapy alone vs. PNFR with eyelid surgery to correct lagophthalmos and prevent the onset of synkinesis. Twenty five outpatients were randomized to receive either PFNR alone (neuromuscular retraining and Kabat proprioceptive neuromuscular facilitation) or PNFR and early (90 days after FP onset) eyelid surgery (involving a conservative oculoplastic correction for lagophthalmos with epiphora or ectropion). Comprehensive otolaryngological assessments and Magnetic Resonance Imaging (MRI) were conducted. Synkinesis progression was measured using Another Disease Scale (ADS) at baseline, 3-, 6-, 12-, and 24-months post-treatment. The data were analyzed with ANOVA, τ-test, Chi-Square analyses. Patients undergoing eyelid surgery with PFNR showed faster (p < 0.001) and better recovery of facial movements (p < 0.05) than patients receiving PFNR alone comparing T0 and T12 (p < 0.0001). No synkinesis were observed in the PFNR plus surgery group while 37% of patients in PFNR alone had synkinesis (p = 0.03). At 24 months, none of the patients in the surgery group presented synkinesis. Combining early surgical treatment of paralytic lagophthalmos or epiphora with PFNR accelerated functional recovery and reduced synkinesis in patients with FP compared to facial rehabilitation alone. Further investigations in larger populations with long-term follow-up are needed. https://clinicaltrials.gov/study/NCT06538103, NCT06538103.

The Effectiveness of Facial Neuromuscular Retraining on Patients with Facial Nerve Dysfunction: A Mental Health and Quality of Life Analysis.

Background: Facial muscle dysfunction can have drastic psychosocial effects. Objectives: To evaluate the impacts of customized neuromuscular retraining on mental health, quality of life (QoL), facial muscle function, and synkinesis. Methods: Thirty patients with facial nerve dysfunction completed a course of neuromuscular retraining. Patients' mental health, QoL, facial muscle function, and synkinesis were evaluated using Patient Health Questionnaire (PHQ-9), Facial Clinimetric Evaluation (FaCE) scale, electronic, clinician-graded facial function scale (eFACE), and Synkinesis Assessment Questionnaire (SAQ) at the initial and final visits. Scores were compared before and after treatment. Results: Patients (n = 30) included had a mean age of 59.4 ± 13.4 years (range 32.3-82.8) and were mostly female (22/30, 73.3%). The most common etiology was Iatrogenic facial nerve paralysis (11/20, 36.7%). Most patients had postfacial paralysis synkinesis (15/30, 50%), while 10 had complete flaccid paralysis. The median house-Brackmann score was 2 (range 1-6). The mean duration of facial palsy was 39.5 ± 106.9 (range 1-576 months). The duration of follow-up after the initial treatment session was 5.5 months, including 10 sessions. After neuromuscular retraining median PHQ-9 scores improved from 5 (range 0-25) to 3 (range 0-20) (p = 0.002). Mean FaCE PROM scores increased from 47.7 ± 11.5 to 56.5 ± 8.8 (p = 0.001). The mean eFACE score increased from 55.8 ± 15.1 to 71.7 ± 13.6 (p < 0.001). Median SAQ score was lower at the final visit (34.6 ± 13.4) compared to the initial visit (47.7 ± 17.8; p < 0.001). Conclusion: Customized neuromuscular retraining may improve patient-reported mental health, QoL, and facial muscle function and reduce synkinesis in facial nerve dysfunction.

Patterns and timing of recovery from facial nerve palsy after nerve-sparing parotid surgery: the role of neuromuscular retraining

ObjectivesAmong the complications of parotid surgery, facial palsy is frequent and burdened by high functional and social impact for the patient. There are few data on the efficacy of facial neuromuscular retraining (FNR) in patients with facial palsy after parotid surgery, and no data exist on its impact in timing and extent of recovery.Material and methodsA retrospective study was conducted on patients undergoing FN sparing parotid surgery and suffering from postoperative facial palsy. Among 400 patients undergoing surgery between July 2016 and May 2023, those with the preservation of the FN and onset of facial palsy were selected. Nerve function was evaluated during 2 years follow up using the House-Brackman (H&Bs) and Sunnybrook scales (SBs).ResultsA total of 46 patients undergoing partial or total parotidectomy were included. At discharge 18 patients (39,1%) had IV to VI grade paralysis according to the H&Bs and the mean SBs value was 54. At 2 and 6 months after surgery, the average value of Sunnybrook increased to 76.5 and 95.4 respectively. After 12 months no patients with IV to VI grade paralysis were represent in our cohort. Two years after surgery, only five patients (10.9%) had persistent grade II paralysis according to HBs.ConclusionsOur study supports the efficacy of FNR in the rehabilitation of facial paralysis after nerve-sparing parotidectomy. The greater functional improvement is achieved within the first 6 months of rehabilitation. A significant improvement is detected still after 18 months, supporting the importance of long rehabilitation for patients without complete recovery after the first year.

Etiology and Management of 800 Patients With Facial Palsy at a Private Practice Setting Over a 5-Year Period.

Very few papers investigated the etiologic breakdown and demographic characteristics of patients with facial nerve (FN) palsy. Our paper aims to present the etiologic breakdown and demographic characteristics of patients with FN palsy, presenting at a private care center between 2014 and 2019, along with the treatment modalities that were offered to them. Charts of 800 patients with facial palsy (FP) were reviewed. Data included the etiology of their diagnosis, family history, recurrent FP, demographic information, and treatment provided before and after presentation. Seventy-five percent of our study population were females. The average period between diagnosis with FP and presentation at our center was 10.8 years. The most commonly identified etiology was Bell's palsy, followed by acoustic neuroma. Eighty-one percent of the study subjects were prescribed steroids and/or antivirals. Facial neuromuscular retraining, electrical stimulation, chemodenervation, and surgical intervention were also part of some treatment plans for our population. Recommendations for the treatment of idiopathic FP include steroids with adjuvant antiviral medications. Data remains uncertain whether the combination therapy of steroids and antivirals has better results compared to steroids alone. Electrical stimulation is still a controversial therapeutic tool for facial paralysis with a potential role in exacerbating synkinesis. The difference in referral patterns between tertiary and private care centers can explain the disparity in the ranking of the etiologies between our study and what has been published. Management of FP is a complex process. The FN community must develop a common database to improve its understanding of the different presentations.

Neuromuscular Control and Resistance Training for People With Chronic Low Back Pain: A Randomized Controlled Trial.

OBJECTIVE: To determine if adding lumbar neuromuscular control retraining exercises to a 12-week program of strengthening exercises had greater effect for improving disability than 12 weeks of strengthening exercises alone in people with chronic low back pain (LBP). DESIGN: Single-center, participant- and assessor-blinded, comparative effectiveness randomized controlled trial. METHODS: Sixty-nine participants (31 females; 29 males; mean age: 46.5 years) with nonspecific chronic LBP were recruited for a 12-week program involving lumbar extension neuromuscular retraining in addition to resistance exercises (intervention) or 12 weeks of resistance exercises alone (control). The primary outcome measure was the Oswestry Disability Index. Secondary outcome measures included the Numeric Rating Scale, Tampa Scale for Kinesiophobia, Pain Self-Efficacy Questionnaire, and the International Physical Activity Questionnaire. Outcomes were measured at baseline, 6 weeks, and 12 weeks. RESULTS: Forty-three participants (22 control, 21 intervention) completed all outcome measures at 6 and 12 weeks. Fourteen participants were lost to follow-up, and 12 participants discontinued due to COVID-19 restrictions. Both groups demonstrated clinically important changes in disability, pain intensity, and kinesiophobia. The difference between groups with respect to disability was imprecise and not clinically meaningful (mean difference, -4.4; 95% CI: -10.2, 1.4) at 12 weeks. Differences in secondary outcomes at 6 or 12 weeks were also small with wide confidence intervals. CONCLUSIONS: Adding lumbar neuromuscular control retraining to a series of resistance exercises offered no additional benefit over resistance exercises alone over a 12-week period.

Effect of botulinum toxin type A in functionality, synkinesis and quality of life in peripheral facial palsy sequelae

ObjectivesThis study aimed to assess the effects of botulinum toxin A (BTX-A) infiltration on face muscle function, synkinesis, and quality of life in patients with sequelae of peripheral facial palsy (PFP). Material and methodsWe present the results of a prospective study including a sample of 20 patients with sequelae of PFP (15 women, 5 men) who underwent BTX-A (Botox© or Xeomin©) infiltration. All patients had previously received personalised treatment with neuromuscular retraining. A clinical assessment was performed before BTX-A infiltration and 4 weeks after treatment. The effect of BTX-A on face muscle function, quality of life, and synkinesis was evaluated using the Sunnybrook Facial Grading System (SFGS), the Facial Clinimetric Evaluation (FaCE) questionnaire, and the Synkinesis Assessment Questionnaire (SAQ), respectively. ResultsMean SFGS scores increased from 64.8 to 69.9 after BTX-A infiltration (P=.004). Increases were also observed in mean total FaCE scores (from 52.42 to 64.5; P<.001) and the mean score on the FaCE social function subscale (from 61.15 to 78.44; P<.001). Mean SAQ scores decreased from 46.22 to 37.55 after BTX-A infiltration (P=.001). ConclusionsBTX-A infiltration increases face muscle function, improves quality of life, and reduces synkinesis in patients with sequelae of PFP.

Measuring the Potential Effects of Mirror Therapy Added to the Gold Standard Facial Neuromuscular Retraining in Patients With Chronic Peripheral Facial Palsy: Protocol for a Randomized Controlled Trial.

Facial neuromuscular retraining (fNMR) is a noninvasive physical therapy widely used to treat peripheral facial palsies. It consists of different intervention methods that aim to reduce the debilitating sequelae of the disease. Recently, the use of mirror therapy in the acute facial palsy and postsurgical rehabilitation contexts has shown promising results, suggesting its use as an adjunct to fNMR in treating patients with later stages of paralysis, such as the paretic, early, or chronic synkinetic. The main aim of this study is to compare the efficacy of an added mirror therapy component with fNMR in patients with peripheral facial palsy (PFP) sequelae in 3 different stages. The specific objectives of this study are to measure the effects of combined therapy compared to fNMR alone on (1) participants' facial symmetry and synkinesis, (2) quality of life and psychological aspects of the participants, (3) motivation and treatment adherence, and (4) different stages of facial palsies. This study is a randomized controlled trial that compares the effect of fNMR combined with mirror therapy (experimental group: n=45) with fNMR alone (control group: n=45) in 90 patients with peripheral facial palsy presenting with sequelae 3-12 months after onset. Both groups will receive 6 months of rehabilitation training. Facial symmetry and synkinesis; participants' quality of life; and their psychological factors, motivation, and compliance will be assessed at baseline (T0), 3 months (T1), 6 months (T2), and 12 months (T3) postintervention. Outcome measures are (1) changes in facial symmetry and synkinesis assessed with facial grading tools, (2) quality of life changes with patient questionnaires, and (3) therapy motivation with a standardized scale, as well as adherence to treatment with metadata. Changes in facial symmetry and synkinesis will be judged by 3 assessors blinded to group assignment. Mixed models and Kruskal-Wallis, chi-square, and multilevel analyses will be conducted according to the appropriate variable type. Inclusion will start in 2024 and is anticipated to be completed in 2027. The 12-month follow-up will be completed with the last patient in 2028. We expect patients included in this study to experience improvement in facial symmetry, synkinesis, and quality of life, regardless of group assignments. A potential benefit of mirror therapy for facial symmetry and synkinesis could be noted for patients in the paretic phase. We hypothesize better motivation and adherence to treatment for the mirror therapy group. The results of this trial may provide new guidelines for PFP rehabilitation with patients dealing with long-term sequelae. It also fills the need for robust evidence-based data in behavioral facial rehabilitation. PRR1-10.2196/47709.

Chemodenervation Algorithm: Functional and Aesthetic Considerations for Facial Harmony in Patients with Post-Facial Paralysis Synkinesis.

Management of post-facial paralysis synkinesis has evolved for the past decade with diversification of neuromuscular retraining, chemodenervation, and advanced surgical reanimation techniques. Chemodenervation with botulinum toxin-A is a commonly used treatment modality for synkinesis patients. Treatment has shifted from solely weakening the unaffected contralateral facial musculature for rote symmetry to selective reduction of undesired or overactive synkinetic muscles, allowing for a more organized motion of the recovered musculature. Facial neuromuscular retraining should be considered a crucial component of treating patients with synkinesis along with soft tissue mobilization, but specifics of these are beyond the scope of this article. Our goal was to create a descriptive platform for our method of chemodenervation treatment in the evolving field of post-facial paralysis synkinesis. A multi-institutional and multidisciplinary comparison of techniques was performed with photograph and video creation, review, and discussion over an electronic platform with all authors. Anatomic specifics of each region of the face and individual muscles were considered. A muscle by muscle algorithm for synkinesis therapy was created to include chemodenervation with botulinum toxin that should be considered for patients suffering from post-facial paralysis synkinesis.

Neuromuscular retraining therapy combined with preceding botulinum toxin A injection for chronic facial paralysis

Background Neuromuscular retraining therapy (NMRT) is the central treatment for synkinesis. The efficacy of botulinum toxin type A (BTX-A) may be enhanced with the addition of physical therapy. Objectives To investigate the effects of NMRT combined with preceding BTX-A injection (NMRT-B) on facial synkinesis and asymmetry in chronic facial paralysis. Materials and Methods We recruited 99 patients with unilateral facial paralysis and no recovery for > 6 months who underwent NMRT-B for > 1 year. The patients were scheduled to receive NMRT after 1–2 weeks of BTX-A injection. We used a computer-based numerical scoring system to evaluate the facial functions. Primary, secondary, and final facial movement scores were evaluated before and after 1 year of treatment. Results Patients with chronic facial paralysis who underwent NMRT-B exhibited improved facial movement after 1 year of treatment. NMRT-B provided satisfactory control of synkinesis and improved the primary movements. The mean primary and final facial movement scores were significantly increased after treatment, while the mean secondary facial movement scores were significantly decreased. Conclusions and significance NMRT-B improved the final facial movement in patients with chronic facial paralysis and synkinesis, regardless of the degrees of facial synkinesis and asymmetry before treatment.

Neuromuscular retraining therapy for early stage severe Bell's palsy patients minimizes facial synkinesis.

To explore whether early physical interventions, including neuromuscular retraining therapy, can minimize excessive movement or any unwanted co-contraction after a severe Bell's palsy. From March 2021 to August 2022, the therapist treated Bell's palsy patients for the acute (<3 months, Group A), subacute (3-6 months, Group B) and chronic (> 6 months, Group C) stages of the condition. We explored whether early physical interventions, including neuromuscular retraining therapy, can minimize facial synkinesis after a severe episode of Bell's palsy. Each patient was informed about the potential for synkinesis and the therapist explained that the main purpose of neuromuscular retraining therapy is to learn new patterns to minimize synkinesis. The facial function of Group A was compared to that of Groups B and C using the 'Synkinesis' scale of the Sunnybrook Facial Grading System. The final facial function score after neuromuscular retraining therapy was significantly associated with both the initial electroneuronographic degeneration rate and initial facial function. Early therapy did not prevent synkinetic movement in 84.7% of the patients. But, there was a significant difference between patients who started early neuromuscular retraining therapy and other groups in final facial function. Synkinesis in Bell's palsy patients can be minimized if physiotherapy commences before synkinesis develops; appropriate neuromuscular retraining therapy timing is essential. A patient with sudden severe Bell's palsy should receive oral steroids as soon as possible, along with physical therapy (including neuromuscular retraining therapy) within 3 months, to minimize synkinesis just before synkinesis onset.

Facial synkinesis: A distressing sequela of facial palsy.

Synkinesis refers to abnormal involuntary facial movements that accompany volitional facial movements. Despite a 55% incidence of synkinesis reported in patients with enduring facial paralysis, there is still a lack of complete understanding of this debilitating condition, leading to functional limitations and decreased quality of life.1 This article reviews the diagnostic assessment, etiology, pathophysiology, rehabilitation, and nonsurgical and surgical treatments for facial synkinesis. A PubMed and Cochrane search was done with no date restrictions for English-language literature on facial synkinesis. The search terms used were "facial," "synkinesis," "palsy," and various combinations of the terms. The resultant inability to control the full extent of one's facial movements has functional and psychosocial consequences and may result in social withdrawal with a significant decrease in quality of life. An understanding of facial mimetic musculature is imperative in guiding appropriate intervention. While chemodenervation with botulinum toxin and neurorehabilitation have continued to be the primary treatment strategy for facial synkinesis, novel techniques such as selective myectomy, selective neurolysis, free-functioning muscle transfer, and nerve grafting techniques are becoming increasingly utilized in treatment regimens. Facial rehabilitation, including neuromuscular retraining, soft tissue massage, and relaxation therapy in addition to chemodenervation with botulinum toxin, remains the cornerstone of treatment. In cases of severe, intractable synkinesis and non-flaccid facial paralysis, surgical interventions, including selective neurectomy, selective myectomy, nerve grafting, or free muscle transfer, may play a more significant role in alleviating symptoms. A multidisciplinary approach involving therapists, clinicians, and surgeons is necessary to develop a comprehensive treatment regimen that will result in optimal outcomes. Ultimately, therapy should be tailored to the severity and pattern of synkinesis, and each patient approached on a case-by-case basis. A multidisciplinary approach involving therapists, clinicians, and surgeons is necessary to develop a comprehensive treatment regimen that will result in optimal outcomes.

Effectiveness of Facial Neuromuscular Retraining with and without Mirror Visual Feedback in Patients with Bell's Palsy

Effectiveness of Facial Neuromuscular Retraining with and without Mirror Visual Feedback in Patients with Bell's Palsy

Neuromuscular Retraining versus BTX-A Injection in Subjects with Chronic Facial Nerve Palsy, A Clinical Trial.

Introduction:Chronic facial nerve palsy has long been known to negatively affect the quality of life in patients. The present study aimed to investigate the efficacy of Botulinum Toxin A (BTX-A) and neuromuscular retraining therapy (NMRT) in the symmetry of chronic facial palsy. Materials and Methods:Two groups, namely experimental and control, were considered each consisting of 13 patients. The study population included a total of 15 female subjects. The BTX-A was injected into the synkinetic muscle in the experimental group; nevertheless, the patients in the second group participated in special neuromuscular retraining. The rate of reducing synkinesis and symmetrical improvement was evaluated using the Facial Grading System (FGS) after 4 months of treatment. The independent t-test was performed to compare the two groups. Results:According to the Sunnybrook FGS, the mean changes in Sunnybrook scores in the experimental and neuromuscular retraining groups were 3% and 24%, respectively. The comparison of the mean scores of the two groups was statistically significant after the interventions (P=0.033). A variable ratio of statistically significant improvement was observed in synkinesis in both groups following the treatment (P=0.041). In addition, by comparing the synkinesis scores between the two groups, the reduction of synkinesis was observed to be greater in the neuromuscular retraining group (P=0.041) after the treatment. Conclusions:The findings of the current study indicated that special neuromuscular retraining leads to significant improvement in the FGS score, compared to botulinum toxin therapy alone. Moreover, it was observed that facial symmetry can be treated with special neuromuscular retraining and the patient can overcome synkinesis.

Muscle Activation During Single-Legged Squat Is Affected by Position of the Nonstance Limb.

The single-legged squat (SLS) is appropriate for targeting activation, strengthening, and neuromuscular retraining of the gluteus maximus, gluteus medius, and quadriceps. However, the effects of different nonstance-limb positions on muscle activity have not been fully evaluated. To compare the muscle activity of selected stance-limb hip muscles during the SLS using 3 nonstance-limb positions: in front (SLS-Front), in the middle (SLS-Middle), and in back (SLS-Back). Controlled laboratory study. Biomechanics laboratory. A total of 17 healthy adults (8 men, 9 women; age = 22.6 ± 3.6 years, height = 173.3 ± 10.7 cm, mass = 71.2 ± 11.0 kg) participated. Surface electromyographic data of the gluteus maximus, gluteus medius, lateral hamstrings, medial hamstrings, rectus femoris, and tensor fascia lata (TFL) as well as kinetic data of the hip and knee were collected while participants performed the 3 SLS tasks. Mean muscle-activation levels during the descent and ascent phases for the selected hip muscles and hip and knee kinetics in all 3 planes were compared for the 3 tasks. Each variable of interest was analyzed using a separate linear regression model with a generalized estimating equations correction. Muscle-activation levels of the gluteus maximus, gluteus medius, medial hamstrings, rectus femoris, and TFL for the stance limb during descent (P ≤ .04) and the medial hamstrings and TFL during ascent (P ≤ .002) were different among the SLS tasks. The greatest number of differences occurred between SLS-Front and SLS-Back. During descent, gluteal muscle activity was greater in SLS-Front (P ≤ .03) and SLS-Middle (P = .03) than in SLS-Back. For both phases, TFL activity was greater during SLS-Front than during both SLS-Middle and SLS-Back (P ≤ .006). Kinetic differences at the hip and knee between SLS tasks were also observed (P values ≤ .02). The 3 SLS tasks had different muscle-activation and kinetic profiles. Clinicians and researchers can vary nonstance-limb position during the SLS to manipulate muscle-activation levels and tailor the exercise to assist with goals at different stages of rehabilitation.

Efecto de la toxina botulínica tipo A en la funcionalidad, las sincinesias y la calidad de vida en secuelas de parálisis facial periférica

ObjectivesThis study aimed to assess the effects of botulinum toxin A (BTX-A) infiltration on face muscle function, synkinesis, and quality of life in patients with sequelae of peripheral facial palsy (PFP). Material and methodsWe present the results of a prospective study including a sample of 20 patients with sequelae of PFP (15 women, 5 men) who underwent BTX-A (Botox® or Xeomin®) infiltration. All patients had previously received personalised treatment with neuromuscular retraining. A clinical assessment was performed before BTX-A infiltration and 4weeks after treatment. The effect of BTX-A on face muscle function, quality of life, and synkinesis was evaluated using the Sunnybrook Facial Grading System (SFGS), the Facial Clinimetric Evaluation (FaCE) questionnaire, and the Synkinesis Assessment Questionnaire (SAQ), respectively. ResultsMean SFGS scores increased from 64.8 to 69.9 after BTX-A infiltration (P=.004). Increases were also observed in mean total FaCE scores (from 52.42 to 64.5; P<.001) and the mean score on the FaCE social function subscale (from 61.15 to 78.44; P<.001). Mean SAQ scores decreased from 46.22 to 37.55 after BTX-A infiltration (P=.001). ConclusionsBTX-A infiltration increases face muscle function, improves quality of life, and reduces synkinesis in patients with sequelae of PFP.

Comparison of the efficacy of electrotherapy and neuromuscular retraining techniques in restoring function of children with obstetric palsy

Background: Obstetric palsy (OP) is defined as the paralysis or paresis of all or part of the upper limb that occurs in the newborn during childbirth. It can be treated surgically and conservatively. Physiotherapy and in particular electrotherapy and neuromuscular retraining techniques help to restore the function of the upper limb. The purpose of this review is to describe and compare recent research data on the efficacy of electrotherapy and neuromuscular retraining techniques in the rehabilitation of infants with OP. The Google Scholar and PubMed databases were searched in English and Greek with the following keywords: obstetric palsy, physiotherapy, electrotherapy, rehabilitation. The review included clinical trials, case studies and systematic reviews. The review included 10 articles: three clinical trials, two case studies, two research articles and three systematic reviews. Conclusions: Electrotherapy and neuromuscular retraining techniques are equally useful methods for treating OP. Electrotherapy is applied during the acute stage, while the techniques begin in the 2nd week of life with the most common choices being the Vojta and Bobath methods and in older age the Proprioceptive Neuromuscular Facilitation and Constraint-Induced Movement Therapy.

Impaired Regulation of Submaximal Force after ACL Reconstruction: Role of Muscle Spindles.

Ongoing motor deficits are routinely present following anterior cruciate ligament (ACL) reconstruction, including the ability to regulate muscle force. While such deficits are known, it is unclear why this occurs. The goal of the current study was to investigate the potential influence of muscle spindle input on submaximal force regulation and muscle activity at the knee in people following ACL reconstruction. Fourteen participants (8 female) who were 6-24 months post-ACL reconstruction and 15 control participants (8 female) undertook submaximal force matching and force modulation tasks before and after 20 min of vibration applied to the patella tendon. Across all tasks, the ACL reconstruction participants were poorer at force matching (P=0.007). The effect of vibration was not significant in either group for the force matching tasks (P=0.06), although there was a reduction in maximum voluntary contraction post-vibration in the control group (P<0.001). The ACL reconstruction group also showed evidence of greater activation of the medial hamstring muscles in comparison to controls (P=0.04). Individuals who have undergone ACL reconstruction have a diminished ability to accurately match and regulate submaximal muscle force, but this does not appear to be related to impaired muscle spindle input. Neuromuscular retraining programs that involve force regulation tasks may be necessary to optimize rehabilitation after ACL reconstruction.

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.

BackgroundFacial 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.ObjectiveThis 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.MethodsSeparate 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.ResultsA 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.ConclusionsThe 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.

Modern approaches to the treatment and rehabilitation of patients with facial neuropathy

Facial nerve neuropathy can manifest itself with gross organic and functional disorders. The esthetic defect worsens social adaptation and quality of life. However, there is no consensus, protocol or algorithm of treatment of the patient with this pathology. In article we present a modern way of treatment and rehabilitation of patients with neuropathy of a facial nerve of various etiology. Conservative and surgical types of treatment are applied during the different periods of a disease. Surgical methods of treatment can be divided into two groups: reconstructive, decompressive and also plastic. The choice of a type of operation is defined individually with many factors, including an etiology and time of a disease. Both the new and tested by time techniques are applied. Conservative therapy includes corticosteroids, antiviral, antibacterial drugs depending on a clinical situation. Traditionally specialists of policlinics and hospitals appoint additional therapy (group B vitamins, cholinesterase inhibitors, antioxidants, neuroprotectors, nootropic drugs), however single small researches couldn't enforce these drugs recommendations. Botulinum toxin type A is effective in the acute and chronic periods of a disease. Depending on a clinical situation of botulinum toxin type A are injected both in affected, and in healthy part of the face. Patients with incomplete eye closure are given keratoprotection as early as possible, and blepharography is performed in case of pronounced deficit. As an alternative method, botulinum toxin type A injections are used into the upper eyelid lifting muscle. One of the most effective methods of rehabilitation of patients with facial nerve neuropathy is therapeutic physical education such as neuromuscular retraining with biological feedback. The most optimal combination is the injection of botulinum toxin type A and therapeutic physical education.
