Health-related quality of life in facial palsy: translation and validation of the Dutch version Facial Disability Index.

PURPOSE: Patient-reported outcome measures are essential in the evaluation of facial palsy. Aim of this study was to translate and validate the Facial Disability Index (FDI) for use in the Netherlands. METHODS: The FDI was translated into Dutch according to a forward-backward method. Construct validity was assessed by formulating 22 hypotheses regarding associations of FDI scores with the Facial Clinimetric Evaluation scale, the Synkinesis Assessment Questionnaire, the Short Form-12 and the Sunnybrook Facial Grading System. Validity was considered adequate if at least 75% (i.e. 17 out of 22) of the hypotheses were confirmed. Additionally, confirmatory factor analysis was performed. Cronbach's α was calculated as a measure of internal consistency. Participants were asked to fill out the FDI a second time after 2 weeks to analyse test-retest reliability. Lastly, smallest detectable change was calculated. RESULTS: In total, 19 hypotheses (86.4%) were confirmed. Confirmatory factor analysis showed acceptable fit for the two factor structure of the original FDI (root mean square error of approximation = 0.064, standardized root mean square residual = 0.081, comparative fit index = 0.925, Chi-square = 50.22 with 34 degrees of freedom). Internal consistency for the FDI physical function scale was good (α > 0.720). Internal consistency for the FDI social/well-being scale was slightly less (α > 0.574). Test-retest reliability for both scales was good (intraclass correlation coefficients > 0.786). Smallest detectable change at the level of the individual was 17.6 points for the physical function and 17.7 points for the social/well-being function, and at group level 1.9 points for both scales. CONCLUSION: The Dutch version FDI shows good psychometric properties. The relatively large values for individual smallest detectable change may limit clinical use. The translation and widespread use of the FDI in multiple languages can help to compare treatment results internationally.

Changes in volume and incidence of lymphedema during and after treatment with docetaxel, doxorubicin, and cyclophosphamide (TAC) in patients with breast cancer.

PURPOSES: The purposes of this study were to investigate the incidence of lymphedema in patients with breast cancer during and after adjuvant treatment with docetaxel, doxorubicin, and cyclophosphamide (TAC), to identify predictors for development of lymphedema, and to describe consequences in daily life in relation to lymphedema. METHODS: This is a prospective study with measurements before chemotherapy (T0), during chemotherapy before cycle 2 (T1), cycle 4 (T2), and 1 month after completion of treatment (T3). Volume change was monitored using tape measurements. Lymphedema was defined as ≥ 10% volume difference. Linear mixed-effect models were estimated to analyze differences in arm volume and consequences in daily life (total score and domain scores of the Lymph-International Classification of Functioning (ICF) questionnaire) over time and to identify treatment and patient characteristics as predictors for changes in volume. RESULTS: Forty-eight patients completed all measurements. Volume did not change during TAC treatment. One month after treatment, volume was significantly increased compared to T0-T2, and 12 patients (25%) had developed lymphedema. Axillary lymph node dissection was associated with lymphedema (ES 2.9, 95% CI 0.02-5.7; p < 0.05). In patients with and without lymphedema, 1 month after completion (T3), the Lymph-ICF questionnaire showed significant limitations in physical function compared to T0-T2. In patients with lymphedema at T3, a significant association between volume and total score on the Lymph-ICF questionnaire on physical function and mobility activities was observed. CONCLUSIONS: One month after treatment in 12 patients (25%), volume difference increased over 10%. Axillary lymph node dissection was predictive for development of lymphedema. All patients, but more patients with lymphedema, perceived difficulties in activities in daily life after treatment.

A prospective cohort study assessing differences in cosmetic appreciation of lateralization while smiling in patients with a peripheral facial palsy.

We investigated the differences in cosmetic appreciation of patients with a left and a right peripheral facial palsy (PFP) while smiling. Smiling pictures of patients with a facial palsy with House-Brackmann II-VI were reversed as a mirror image and offered as a pair of pictures, together with the true image. Twenty-six patients with a PFP and 24 medical professionals familiar with facial palsy were asked to choose the most attractive photograph. Patients rated their own pictures. Medical professionals preferred pictures of patients with a right and left PFP in, respectively, a mean of 43.00 ± 12.25% and 57.00 ± 12.28% (p = .005). Patients with a right PFP chose their mirror and true image in 65% and 35% in smiling pictures (p = .01). Patients with a left PFP facial palsy chose their mirror and true image in 58% and 42% in smiling pictures (p = .02). The House-Brackmann score and age of the patients did not influence preferences of medical professionals and patients. We have found that medical professionals have a significant preference for pictures of patients with a left PFP. Patients with a left PFP and right PFP significantly prefer their mirror image in smiling pictures.

Quality of life assessment in facial palsy: validation of the Dutch Facial Clinimetric Evaluation Scale.

This study aimed at validating an existing health-related quality of life questionnaire for patients with facial palsy for implementation in the Dutch language and culture. The Facial Clinimetric Evaluation Scale was translated into the Dutch language using a forward-backward translation method. A pilot test with the translated questionnaire was performed in 10 patients with facial palsy and 10 normal subjects. Finally, cross-cultural adaption was accomplished at our outpatient clinic for facial palsy. Analyses for internal consistency, test-retest reliability, construct validity and responsiveness were performed. Ninety-three patients completed the Dutch Facial Clinimetric Evaluation Scale, the Dutch Facial Disability Index, and the Dutch Short Form (36) Health Survey. Cronbach's α, representing internal consistency, was 0.800. Test-retest reliability was shown by an intraclass correlation coefficient of 0.737. Correlations with the House-Brackmann score, Sunnybrook score, Facial Disability Index physical function, and social/well-being function were -0.292, 0.570, 0.713, and 0.575, respectively. The SF-36 domains correlate best with the FaCE social function domain, with the strongest correlation between the both social function domains (r = 0.576). The FaCE score did statistically significantly increase in 35 patients receiving botulinum toxin type A (P = 0.042, Student t test). The domains 'facial comfort' and 'social function' improved statistically significantly as well (P = 0.022 and P = 0.046, respectively, Student t-test). The Dutch Facial Clinimetric Evaluation Scale shows good psychometric values and can be implemented in the management of Dutch-speaking patients with facial palsy in the Netherlands. Translation of the instrument into other languages may lead to widespread use, making evaluation and comparison possible among different providers.

TheraBite exercises to treat trismus secondary to head and neck cancer.

PURPOSE: The aim of this study was to evaluate the effect of TheraBite exercises on mouth opening and to analyze factors influencing this effect in a patient record evaluation. METHODS: Effect of exercises with a TheraBite to treat trismus was evaluated in 69 head and neck cancer patients of two university medical centers. Mouth opening was measured as interincisal distance in millimeters. Patient, tumor, and treatment characteristics were analyzed for their relationship with change in mouth opening. Variables univariately associated (p ≤ 0.05) with change in mouth opening were entered in a logistic regression analysis as possible predictors for an increase in mouth opening of the smallest detectable difference of 5 mm or more. RESULTS: Mean initial mouth opening was 22.0 mm (SD 6.4); mean increase in mouth opening was 5.4 mm (SD 5.7). "Chemotherapy", "medical center", and "time from oncological treatment to start exercises" were significantly associated with an increase in mouth opening. In the logistic regression analysis, "medical center" (ß = 1.97) and "time from oncological treatment to start exercises" reduced the odds of reaching an increase in mouth opening of 5 mm or more, ß = -0.11 per month. CONCLUSIONS: After TheraBite exercises, mouth opening increased averagely with 5.4 mm. The odds of an increase in mouth opening of 5 mm or more reduces if the time from oncological treatment to start exercises lengthens, corrected for the effect of medical center.

Psychological counselling in patients with a peripheral facial palsy: initial experience from an expert centre.

BACKGROUND: The aims of this pilot study were to evaluate the psychologist's role on the multidisciplinary team during peripheral facial palsy (PFP) patient care and to identify the potential predictors of anxiety and depressive symptoms/disorders in PFP patients. METHODS: Using the prospective non-controlled study design, PFP patients aged 18-75 years who presented to the Radboud Facial Palsy Expert Centre, the Netherlands, were enrolled during a 1-year interval. The main outcome variables were 1) anxiety and depression in relation to PFP using the Hospital Anxiety and Depression Scale (HADS) and 2) the outcome of psychological counselling in patients with a HADS score ≥ 8. RESULTS: A sample comprised 25 patients (68% females, 56% right-side PFP, 16% House-Brackmann scale I-II) with a mean age of 50 ± 14 years were referred to a psychologist. The proportion of patients with a HADS score ≥8, were 16 (64%) and 13 (52%), respectively. Especially, coping (in general or coping with the disease, 48%) and/or help with the choice of possible surgery (8.0%) were important reasons for counselling. In one case, a patient had chronic fatigue syndrome and was therefore referred to a psychological specialist centre. One patient was treated with acceptance and commitment therapy (ACT) with good results. CONCLUSIONS: Despite a small sample size and limited statistical analyses, the results of this study suggest that one-eighth of the PFP patients require psychological evaluation and treatments. This pilot study emphasises the important role of psychological screening and counselling in PFP patient care.

Cosmetic appreciation and emotional processing in patients with a peripheral facial palsy: A systematic review.

Background; The goal of this review is 1) to summarize the studies assessing PFP by casual observers, patients themselves and the cosmetic appreciation of the PFP and 2) to summarize the studies assessing whether there is a difference in emotional recognition/processing of facial emotions and/or cognitive tasks in patients with a PFP. Materials and Methods; A multi-database systematic literature search was performed using the following databases: Pubmed, Embase, Medline, and The Cochrane Library from the earliest date of each database up to December 2019. Population of interest consisted of patients with a PFP and studies that investigated cosmetic appreciation and/or emotional recognition and/or emotional processing in these patients. Two authors rated the methodological quality of the included studies independently using the 'Newcastle - Ottawa Quality Assessment Scale' for nonrandomised studies' (NOS). Two authors extracted the outcome data regarding cosmetic appreciation and/or emotional recognition/processing from the included studies. Results; Twelve hundred and thirty-two studies were found of which eleven studies met the inclusion criteria. Most studies were assessed to be of 'fair' to 'good' methodological quality. The Cohen's kappa (between author RL and SP) was 0.68. Two studies investigated emotional processing and/or emotional recognition. Nine studies investigated cosmetic appreciation in both patients and casual observers. Important findings of this systematic review are that there is a correlation between the perceived severity of the PFP of the patients and the ratings by casual observers. Secondly there seems to be a laterality difference in cosmetic appreciation and thirdly there might to be a decreased emotional recognition and processing in patients with a PFP. Conclusion; Emotional recognition and cosmetic appreciation in patients with a PFP is an under investigated area, in which further studies are needed to substantiate the findings in current literature.

Association between duration of peripheral facial palsy, severity, and age of the patient, and psychological distress.

BACKGROUND: Peripheral facial palsy (PFP) (paralysis) can be a devastating condition that has been shown to have associations with increased depression and worse quality of life. The aim of the present study is to better understand the complex association of psychological distress with the duration, severity, and age of patients with PFP. We hypothesize that a shorter duration of PFP is associated with higher levels of psychological distress. METHODS: Fifty-nine patients with PFP that existed longer than 3 months were included in this study. The Hospital Anxiety and Depression Scale (HADS) was used to assess the presence and severity of anxiety and depressions. Spearman's correlation analysis was used to determine correlation between psychological distress, duration, severity of the PFP, and age. RESULTS: Fifty-nine patients were included in this study, of whom 22 were male and 37 were female. The mean age was 55.6 ±â€¯14.6 years and mean duration of PFP from onset ranged from 3 months to 35 years (with a mean duration of 5.39 ±â€¯6.06 years). Twenty-eight patients had left-sided PFP, 30 patients had right-sided PFP, and one patient had bilateral PFP. The majority were caused by Bell's palsy (50.8%). In the group with a duration less than 5 years, there were five (12.8%) patients having a score between 11 and 15 (on HADS) compared to two (10%) patients in the group with a duration of 5 years or more(p = 0.04). CONCLUSION: There seems to be an association between moderate depression and duration of the PFP. Further studies need to substantiate our findings.

A closer look at the paralyzed face; a narrative review of the neurobiological basis for functional and aesthetic appreciation between patients with a left and a right peripheral facial palsy.

BACKGROUND: The facial nerve or n. facialis (NVII) is the seventh cranial nerve and it is responsible for the innervation of the mimic muscles, the gustatory organ, and the secretomotor function to the salivary, lacrimal, nasal and palatine glands. Clinical presentation of Facial Palsy (FP) is characterized by unilateral facial asymmetry and may present with a change in taste, decreased saliva production, and dysarthria. A facial palsy has a notable effect on the facial appreciation by both the patient and the environment and also affects quality of life and emotional processing. There appear to be differences in the appreciation of people with a left and right facial palsy. PURPOSE OF THIS REVIEW: The purpose of the review is to give an overview of the anatomy of the facial nerve, neuro-anatomy of face processing, and hemispheric specialization and lateralization. Further,an overview is given of the clinical studies that translated the neuro-anatomical and neurobiological basis of these concepts into clinical studies. What this review adds: This review emphasizes the neurobiological evidence of differences in face processing between the left and right cerebral hemisphere, wherein it seems that the right hemisphere is superior in emotional processing. Several theories are proposed; 1) a familiarity hypothesis and 2) a left-right hemispheric specialization hypothesis. In clinical studies, promising evidence might indicate that, in patients with FP, there is indeed a difference in how left and right FP are perceived. This might give differences in decreased quality of life and finally in occurrence of depression. Further research must aim to substantiate these findings and determine the need for altering the standard therapeutic advice given to patients.

Accuracy of a single measurement site for self-monitoring of patients with breast cancer at risk for lymphedema.

Purpose: Early detection of breast cancer-related lymphedema through simple self-monitoring techniques may lead to early treatment and improved outcomes. Methods: Prospective study of circumference measurements at four time points before, during, and after adjuvant chemotherapy with docetaxel, doxorubicin, and cyclophosphamide. Volume was calculated using the 10-cm interval circumference measurement method (reference test) and percentage difference between arms, for volume and circumference, was determined. First, the most valid single measurement location was determined by calculating Pearson's correlation coefficient relative to the reference test. Second, to evaluate the responsiveness to change over four time points, outcomes of the selected single measurement and the reference test were analyzed by repeated-measures ANOVA. Third, area under the curve (AUC) was used to determine the optimal sensitivity and specificity of the selected single measurement site (index test). Relationship between lymphedema (yes/no) and heaviness and swelling (yes/no) was analyzed using phi-coefficient. Results: The measurement point 30 cm proximal to the styloid process showed the highest correlation with percentage difference in total arm volume (r = 0.80) and detected increased percentage difference between arms after treatment. Analyses showed high accuracy (AUC = 0.94; 95% CI 0.90-0.99) and good sensitivity (0.85) and specificity (0.85) using a cutoff score of 4% circumference difference between arms at this location. A moderate correlation between feelings of heaviness and swelling to lymphedema was observed (rφ = 0.64). Conclusions: Circumference difference between arms of 4% measured at 30 cm proximal to the styloid process can be used as a surveillance site for further monitoring of patients at risk for lymphedema and may contribute to early diagnosis. Feelings of heaviness or swelling have moderate relationship with lymphedema, which needs to be confirmed in clinical practice.

The efficacy of physiotherapy upon shoulder function following axillary dissection in breast cancer, a randomized controlled study.

BACKGROUND: Many patients suffer from severe shoulder complaints after breast cancer surgery and axillary lymph node dissection. Physiotherapy has been clinically observed to improve treatment of these patients. However, it is not a standard treatment regime. The purpose of this study is to investigate the efficacy of physiotherapy treatment of shoulder function, pain and quality of life in patients who have undergone breast cancer surgery and axillary lymph node dissection. METHODS: Thirty patients following breast cancer surgery and axillary lymph node dissection were included in a randomised controlled study. Assessments were made at baseline and after three and six months. The treatment group received standardised physiotherapy treatment of advice and exercises for the arm and shoulder for three months; the control group received a leaflet containing advice and exercises. If necessary soft tissue massage to the surgical scar was applied. Primary outcome variables were amount of pain in the shoulder/arm recorded on the Visual Analogue Scale, and shoulder mobility (flexion, abduction) measured using a digital inclinometer under standardized conditions. Secondary outcome measures were shoulder disabilities during daily activities, edema, grip strength of both hands and quality of life. The researcher was blinded to treatment allocation. RESULTS: All thirty patients completed the trial. After three and six months the treatment group showed a significant improvement in shoulder mobility and had significantly less pain than the control group. Quality of life improved significantly, however, handgrip strength and arm volume did not alter significantly. CONCLUSION: Physiotherapy reduces pain and improves shoulder function and quality of life following axillary dissection after breast cancer.

Depth accuracy of the RealSense F200: Low-cost 4D facial imaging.

The RealSense F200 represents a new generation of economically viable 4-dimensional imaging (4D) systems for home use. However, its 3D geometric (depth) accuracy has not been clinically tested. Therefore, this study determined the depth accuracy of the RealSense, in a cohort of patients with a unilateral facial palsy (n = 34), by using the clinically validated 3dMD system as a gold standard. The patients were simultaneously recorded with both systems, capturing six Sunnybrook poses. This study has shown that the RealSense depth accuracy was not affected by a facial palsy (1.48 ± 0.28 mm), compared to a healthy face (1.46 ± 0.26 mm). Furthermore, the Sunnybrook poses did not influence the RealSense depth accuracy (p = 0.76). However, the distance of the patients to the RealSense was shown to affect the accuracy of the system, where the highest depth accuracy of 1.07 mm was measured at a distance of 35 cm. Overall, this study has shown that the RealSense can provide reliable and accurate depth data when recording a range of facial movements. Therefore, when the portability, low-costs, and availability of the RealSense are taken into consideration, the camera is a viable option for 4D close range imaging in telehealth.

Quality of life before and after different treatment modalities in peripheral facial palsy: A systematic review.

OBJECTIVES: A systematic review was conducted to investigate the effect of peripheral facial palsy (PFP) on the quality of life (QoL). Secondly, we investigated if different treatment modalities influence the QoL of patients with PFP. METHODS: A multidatabase systematic literature search was performed using the following databases: PubMed, Embase, MEDLINE, and The Cochrane Library from the earliest date of each database up to August 2015. The inclusion criteria were either prospective and/or retrospective cohort trials and/or case series measurement of QoL before and after treatment, patients with PFP (irrespective of etiology), and various treatment modalities (medication, physical therapy, botulinum toxin injections, and several types of surgical procedures). Two authors rated the methodological quality of the included studies independently using the Newcastle-Ottawa Quality Assessment Scale for nonrandomized studies. RESULTS: Two hundred fifty-eight studies were found, of which 14 studies met the inclusion criteria. Most studies were assessed to be of fair to good methodological quality. The Cohen's κ (between author r.e.l. and s.p.) was 0.68. Eight different questionnaires were used to measure QoL, of which the Facial Clinimetric Evaluation scale was used most frequent. After different modalities, all studies showed significant improvements in terms of QoL. CONCLUSIONS: This study found significant improvement when measuring QoL before and after different treatment modalities in patients with peripheral facial palsy. Future research should focus on patients with PFP due to the same etiology and use of valid QoL instruments for outcome measures. Laryngoscope, 127:1044-1051, 2017.

Stability of benefits of mime therapy in sequelae of facial nerve paresis during a 1-year period.

OBJECTIVE: To assess the stability of benefits of mime therapy, a modality of physiotherapy for patients with facial nerve paresis, during a period of 1 year. STUDY DESIGN: A prospective follow-up build on a randomized clinical trial in which a treatment group is compared with a control group. SETTING: Physiotherapy outpatient department. PATIENTS: Forty-eight patients with a history of a facial nerve paresis of 9 months or more. INTERVENTION: Mime therapy. METHOD: Sequelae of facial nerve paresis were measured using the same measurement instruments as in the randomized clinical trial--the Sunnybrook and the House-Brackmann (HB) Facial Grading Systems, the lip length and pout indices, a stiffness scale, and the Facial Disability Index. Stability of outcome level and of interpatient differences is analyzed. RESULTS: Of the 46 patients who completed the follow-ups, repeated-measures analyses of covariance revealed no significant differences in the average scores nor significant trends of the posttherapy measurements, except for the pout index and the Facial Disability Index-social. For six sequelae (except HB), 95% of patient-sequel combinations showed immediate improvement after mime therapy, for HB grades this was 74%. Where sequelae improved, the posttherapy individual courses (T2-T3-T4) showed, also for HB, in majority absence of deterioration; benefits obtained were stable. CONCLUSION: Mime therapy is effective in patients with facial nerve paresis and benefits are stable 1 year after therapy.

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

QUESTION: What is the effect of mime therapy on facial symmetry and severity of paresis in people with facial nerve paresis? DESIGN: Randomised controlled trial. PARTICIPANTS: 50 people recruited from the Outpatient department of two metropolitan hospitals with facial nerve paresis for more than nine months. INTERVENTION: The experimental group received three months of mime therapy consisting of massage, relaxation, inhibition of synkinesis, and co-ordination and emotional expression exercises. The control group was placed on a waiting list. OUTCOME MEASURES: Assessments were made on admission to the trial and three months later by a measurer blinded to group allocation. Facial symmetry was measured using the Sunnybrook Facial Grading System. Severity of paresis was measured using the House-Brackmann Facial Grading System. RESULTS: After three months of mime therapy, the experimental group had improved their facial symmetry by 20.4 points (95% CI 10.4 to 30.4) on the Sunnybrook Facial Grading System compared with the control group. In addition, the experimental group had reduced the severity of their paresis by 0.6 grade (95% CI 0.1 to 1.1) on the House-Brackmann Facial Grading System compared with the control group. These effects were independent of age, sex, and duration of paresis. CONCLUSION: Mime therapy improves facial symmetry and reduces the severity of paresis in people with facial nerve paresis.

Assessing psychological distress in patients with facial paralysis using the Hospital Anxiety and Depression Scale.

OBJECTIVES: Anxiety and depression are seen among patients with facial paralysis (FP), but less is known about the exact prevalence. The aim of the current study is to assess the prevalence of anxiety and depressive disorders in the FP population and to investigate possible differences between patients with left- and right-sided FP. METHODS: Fifty-nine patients with FP and 59 healthy individuals were included in this study between March and December of 2014. The Hospital Anxiety and Depression Scale was used to assess the prevalence of anxiety and depression among these groups. RESULTS: The mean age of the patients and controls was 56 ± 15 and 40 ± 16 years, respectively. Twenty-eight patients had left-sided FP, 30 patients had right-sided FP, and one patient had bilateral FP. In the patient group, approximately 30% had anxiety and 25% had a depressive disorder. Compared with the control group, significantly more patients presented with mild anxiety (p = 0.031), mild depression (p = 0.047), and moderate depression (p = 0.006). No significant differences were found in terms of the prevalence of anxiety between left- and right-sided FP. However, significantly more patients with left-sided FP had mild depression (p = 0.018) than those with right-sided FP. CONCLUSION: This study found a significant difference in anxiety and depression between patients with FP and healthy controls. No clinically significant difference was noted in the prevalence of anxiety or depression between patients with left- and right-sided FP.

Synkinesis assessment in facial palsy: validation of the Dutch Synkinesis Assessment Questionnaire.

The objective of this study is to validate an existing health-related quality of life questionnaire for patients with synkinesis in facial palsy for implementation in the Dutch language and culture. The Synkinesis Assessment Questionnaire was translated into the Dutch language using a forward-backward translation method. A pilot test with the translated questionnaire was performed in 10 patients with facial palsy and 10 normal subjects. Finally, cross-cultural adaption was accomplished at our outpatient clinic for facial palsy. Analyses for internal consistency, test-retest reliability, and construct validity were performed. Sixty-six patients completed the Dutch Synkinesis Assessment Questionnaire and the Dutch Facial Disability Index. Cronbach's α, representing internal consistency, was 0.80. Test-retest reliability was 0.53 (Spearman's correlation coefficient, P < 0.01). Correlations with the House-Brackmann score, Sunnybrook score, Facial Disability Index physical function, and social/well-being function were -0.29, 0.20, -0.29, and -0.32, respectively. Correlation with the Sunnybrook synkinesis subscore was 0.50 (Spearman's correlation coefficient). The Dutch Synkinesis Assessment Questionnaire shows good psychometric values and can be implemented in the management of Dutch-speaking patients with facial palsy and synkinesis in the Netherlands. Translation of the instrument into other languages may lead to widespread use, making evaluation, and comparison possible among different providers.

Measurement Properties of Instruments for Measuring of Lymphedema: Systematic Review.

BACKGROUND: Lymphedema is a common complication of cancer treatment, resulting in swelling and subjective symptoms. Reliable and valid measurement of this side effect of medical treatment is important. PURPOSE: The purpose of this study was to provide best evidence regarding which measurement instruments are most appropriate in measuring lymphedema in its different stages. DATA SOURCES: The PubMed and Web of Science databases were used, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. STUDY SELECTION: Clinical studies on measurement instruments assessing lymphedema were reviewed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) scoring instrument for quality assessment. DATA EXTRACTION: Data on reliability, concurrent validity, convergent validity, sensitivity, specificity, applicability, and costs were extracted. DATA SYNTHESIS: Pooled data showed good intrarater intraclass correlation coefficients (ICCs) (.89) for bioimpedance spectroscopy (BIS) in the lower extremities and high intrarater and interrater ICCs for water volumetry, tape measurement, and perometry (.98-.99) in the upper extremities. In the upper extremities, the standard error of measurement was 3.6% (σ=0.7%) for water volumetry, 5.6% (σ=2.1%) for perometry, and 6.6% (σ=2.6%) for tape measurement. Sensitivity of tape measurement in the upper extremities, using different cutoff points, varied from 0.73 to 0.90, and specificity values varied from 0.72 to 0.78. LIMITATIONS: No uniform definition of lymphedema was available, and a gold standard as a reference test was lacking. Items concerning risk of bias were study design, patient selection, description of lymphedema, blinding of test outcomes, and number of included participants. CONCLUSIONS: Measurement instruments with evidence for good reliability and validity were BIS, water volumetry, tape measurement, and perometry, where BIS can detect alterations in extracellular fluid in stage 1 lymphedema and the other measurement instruments can detect alterations in volume starting from stage 2. In research, water volumetry is indicated as a reference test for measuring lymphedema in the upper extremities.

Contralateral reinnervation of midline muscles in nonidiopathic facial palsy.

The purpose of this study was to analyze contralateral reinnervation of the facial nerve in eight patients with complete facial palsy after surgery or trauma and seven healthy volunteers. All patients had contralateral reinnervation of facial muscles as demonstrated by electrical nerve stimulation versus none of the control subjects. Four patients had facial muscle movements at the site of the damaged nerve. In one patient this was entirely the result of contralateral reinnervation, whereas the other three patients had innervation both ipsilaterally and contralaterally. This implies that renewed facial muscle activity should be examined considering the origin of the reinnervation, either contralateral or ipsilateral. Contralateral reinnervation is a common phenomenon after total facial palsy and can occur alongside ipsilateral reinnervation. It can be mistaken for adequate reinnervation of the damaged nerve, causing postponement of dynamic reconstruction therapy.

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

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