Facial Synkinesis

Background: There is no current standard for facial synkinesis rehabilitation programs. The benefit and stability of effect of an intensified 10-day facial training combining electromyography and visual biofeedback training was evaluated.Methods: Fifty-four patients (77.8% female; median age: 49.5 years) with post-paralytic facial synkinesis (median time to onset of paralysis: 31.1 months) were included in retrospective longitudinal study between January 2013 and June 2016. Facial function was assesses at baseline (T0), first days of training (T1), last day of training (T2), and follow-up visit (T3) at a median time of 6 months later using the House-Brackmann (HB) facial nerve grading system, Stennert index (SI), Facial Nerve Grading System 2.0 (FNGS 2.0), and Sunnybrook Facial Grading System (SFGS). Pairwise comparisons between the time points with post-hoc Bonferroni correction were performed.Results: No significant changes of the gradings and subscores were seen between T0 and T1 (all p > 0.01). The 10-day combined and intensified feedback training between T1 and T2 improved facial symmetry and decreased synkinetic activity. Facial grading with the FNGS 2.0 or the SFGS were most suited to depict the training effect. FNGS 2.0, regional score, FNGS 2.0, synkinesis score, and FNGS 2.0 total score improved significantly (all p ≤ 0.0001). Both, the FNGS 2.0 and the SFGS showed the strongest improvement in the nasolabial fold/zygomatic and the oral region. Neither the age of the patient (r = 0.168; p = 0.224), the gender (r = 0.126; p = 0.363) nor the length of the interval between onset of the palsy and training start (r = 0.011; p = 0.886) correlated with the changes of the SFGS between T1 and T2. The results remained stable between T2 and T3 without any further significant change.Conclusion: Intensified daily combined electromyography and visual biofeedback training over 10 days was effective in patients with facial synkinesis and benefits were stable 6 months after therapy.

Compound Muscle Action Potentials

Twenty normal individuals were submitted to facial nerve electroneurography using different techniques in order to determine the most accurate to obtain the latencies and amplitudes of the compound muscle action potentials (CMAP) of the facial muscles. First of all it was determined in which muscle or muscle group highest amplitude CMAP could be recorded with the lowest variability between sides and in test-retest. Different techniques were studied in order to determine which could give the best results. This was shown to be an arrangement of bipolar surface electrodes fixed to a plastic bar. The records with higher amplitude where obtained from the nasolabial fold muscles. Therefore 65 normal volunteers were examined using this technique and recording the potentials obtained over the nasolabial fold muscles. Normal values were determined (latency lower than 4.5 ms and amplitude larger than 2 mV - 95% confidence limits).

Objectives: The aim of the study was to determine the prognosis of children with Bell’s palsy and analyze the prognostic factors affecting early recovery. Methods: The records of children with a diagnosis of Bell’s palsy were retrospectively analyzed. Demographic and clinical features including age, gender, House-Brackmann Facial Nerve Grading System House-Brackmann Grading Scale (HBGS) grade at admission and follow-up, and the dosage and onset of steroid treatment were reviewed. Laboratory findings such as red blood cell distribution width and neutrophil-to-lymphocyte ratio were noted. The patients who were recovered within the first month (early recovery) were compared with the patients who were recovered after first month (late recovery) in terms of demographic, clinical characteristics, laboratory findings and treatment modalities in order to determine the risk factors affecting early recovery. Results: A total of 102 children (65 girls and 37 boys) with a mean age of 10.37 ± 4.2 years were included in the study. The complete recovery was detected in 101 children (%99) with Bell’s palsy. Statistically significant difference was found in terms of dosage and time of onset of steroid treatment ( P = .04, P = .035, respectively) and House-Brackmann Facial Nerve Grading System grade on the 10th day ( P = .001) between the early and late recovery groups. Conclusion: The prognosis of Bell’s palsy in children was very good. The prognostic factors affecting the early recovery were being House-Brackmann Facial Nerve Grading System grade 2 or 3 on the 10th day and receiving steroid treatment in the first 24 hours. Neutrophil-to-lymphocyte ratio and red blood cell distribution width were not found to be predictive factors for early recovery.

Eeg Alpha

The study asks whether voluntary control over the relative appearance of EEG alpha in midline frontal and parietal sites can be achieved with auditory biofeedback training. 16 Ss participated in the training and testing regimen. Ss varied in the number of hour-long single-channel feedback training sessions received. In the test period, dual-channel feedback was given, and Ss were asked to increase the ratio of frontal to parietal alpha and then the reverse. Evidence for small but significant control is presented. Amount of control was correlated with number of practice sessions.
