This text is the continuation of the XVIII SBFa Congress publication. In part "A" we presented the analyses on clinical vocal evaluation. Part "B" focuses on vocal rehabilitation: 4. Traditional techniques of vocal therapy; 5. Modern techniques of electrostimulation and photobiomodulation applied to vocal rehabilitation. The numerous studies on the various programs, methods, and techniques of traditional rehabilitation techniques, and many with high quality of evidence, allow us to consider such procedures relatively well described, safe, and with known effects, accounting for the treatment of various vocal disorders. The scientific evidence with traditional techniques is recognized worldwide. New fronts of evolution, with electrostimulation or photobiomodulation used to handle voice problems, seem to be promising as coadjutant approaches. There are more studies on electrostimulation in vocal rehabilitation than with photobiomodulation; however, scientific evidence for these two modern techniques is still limited. Knowledge and caution are required for the application of either technique.

During the XXVIII Brazilian Congress of SBFa, 24 specialists met and, from a leading position on scientific research as a tool for connecting laboratory and clinic, five fronts of knowledge of the voice specialty were discussed as following: Perceptual-auditory judgment of vocal quality; 2. Acoustic analysis of the vocal signal; 3. Voice self-assessment; 4. Traditional techniques of therapy; 5. Modern techniques of electrostimulation and photobiomodulation (PBMT) in voice. Part "a" of this publication was associated with the consolidation of the analyses of the first three aspects. The trend in the perceptual-auditory judgment of vocal quality was related to the use of standard protocols. The acoustic evaluation of the vocal signal is accessible and can be done descriptively or by extraction of parameters, thus preferring multiparametric measures. Finally, the analysis of the individual himself closes this triad of voice documentation, which will be the basis for the conclusion of the evaluation, reference for monitoring progress, and evaluation of treatment results.

Unlabelled: Dystonia is a central motor processing neurological disorder characterized by abnormal, often action-induced, involuntary movements or uncontrolled spasms., Aim: To compare patients with the diagnoses of focal and segmental adductor laryngeal dystonia at the Neurolarynx Outpatient Clinic of the Federal University of São Paulo., Materials and Methods: A clinical retrospective study of data collected from patient registries from 2003 to 2009., Results: Of 34 patients, 25 presented focal dystonia and 9 presented segmental dystonia. There were 30 females (88. 2%) and 4 males (11. 8%). A relation with a traumatic event was reported in 11 cases (32. 4%). Vocal tremor was observed in 21 patients (61. 8%). The mean age at onset, the age at diagnosis, and time between the onset and the diagnosis were respectively 55, 61. 3 and 6. 3 years. There was no statistical difference between patients with focal laryngeal adductor dystonia and segmental dystonia in the study data., Conclusions: There were no statistical differences among patients with focal adductor laryngeal dystonia and segmental dystonia relating to age of onset, age of diagnosis, gender, time between onset and diagnosis, presence of associated tremor, and relation to trauma.
