  • 3D facial video retrieval and management for decision support in speech and language therapy
    Publication . Carrapiço, Ricardo; Guimarães, Isabel; Grilo, Ana Margarida; Cavaco, Sofia; Magalhães, João
    3D video is introducing great changes in many health related areas. The realism of such information provides health professionals with strong evidence analysis tools to facilitate clinical decision processes. Speech and language therapy aims to help subjects in correcting several disorders. The assessment of the patient by the speech and language therapist (SLT), requires several visual and audio analysis procedures that can interfere with the patient's production of speech. In this context, the main contribution of this paper is a 3D video system to improve health information management processes in speech and language therapy. The 3D video retrieval and management system supports multimodal health records and provides the SLTs with tools to support their work in many ways: (i) it allows SLTs to easily maintain a database of patients' orofacial and speech exercises; (ii) supports three-dimensional orofacial measurement and analysis in a non-intrusive way; and (iii) search patient speech-exercises by similar facial characteristics, using facial image analysis techniques. The second contribution is a dataset with 3D videos of patients performing orofacial speech exercises. The whole system was evaluated successfully in a user study involving 22 SLTs. The user study illustrated the importance of the retrieval by similar orofacial speech exercise.

  • Accuracy of acoustic evaluation of swallowing as a diagnostic method of dysphagia in individuals affected by stroke: preliminary analysis
    Publication . Enz, Vivian; Vaz, Amanda; Nunes, Maria Cristina; Rosa, Marcelo; Nunes, Janaína; Marques, Jair; Santos, Rosane Sampaio
    After a stroke, more than half of the patients have some kind of disability, and dysphagia is frequently found. Cervical auscultation by Doppler sonar is an innovative technique with gain of credibility in the clinical evaluation of swallowing. To verify the diagnostic accuracy of Doppler sonar along with the DeglutiSom® software as an auxiliary method in the evaluation of oropharyngeal dysphagia in patients after stroke. The research is a cross-sectional, uncontrolled, blind, quantitative study with systematic random sampling. Patients from inpatient and outpatient units of a reference hospital with a stroke care unit were concomitantly submitted to both Doppler sonar and Fiberoptic Endoscopic Evaluation of Swallowing (FEES®). Seventy-three audio files collected from 26 patients through Doppler sonar were analyzed using DeglutiSom® software and confronted with the FEES® report, regarding three food consistencies offered to them during the exam. The study showed that the Doppler sonar correctly identified, among all the analyzed files, those that actually presented tracheal aspiration as well as it effectively identified patients who did not aspirate. The Youden index of 0.91 corroborates this information, showing a promising accuracy in detecting tracheal aspiration in the studied sample. The study evaluates the diagnostic accuracy of Doppler sonar, showing that it can be used as a valuable tool in the diagnosis of tracheal aspiration in patients after stroke. It is important to emphasize that the identification of residue by this method requires further studies. Also, larger sample size and more than one blind evaluator should be considered in future researches to increase the reliability of the proposed method.

  • Acoustic analysis of swallowing as an auxiliary method for assessing dysphagia in Parkinson's disease
    Publication . Silva, Glauce; Figueiredo, Ana Clara; Zeigelboim, Bianca; Araújo, Cristiano; Neto, José; Santos, Rosane Sampaio
    Objective: To measure the accuracy of DeglutiSom as an auxiliary method to assess swallowing in patients with Parkinson's disease (PD). Methodology: Accuracy study. Among 248 individuals, 91 participants met the inclusion criteria, with a mean age of 64.9 years (SD 7.7), 53.8% male and 46.2% female, with a mean disease duration of 12.6 years (SD 3.8 years). Two instrumental studies were performed: An acoustic analysis with Sonar Doppler via the DeglutiSom Software, and a videofluoroscopic swallow study. Three judges analyzed the swallowing sounds in the DeglutiSom software and the instrumental examination findings. Results: The inter-rater reliability was 90.1%, with 4.4% degree of partial agreement and 5.5% disagreement. Sensitivity resulted in 90.0% and specificity in 90.0%. A sensitivity of 97.0% and specificity of 91.0% are indicators of a high validity for the dysphagia screening method, with predictive value (+) of 97.0% and predictive value (-) of 91.0%, with an accuracy method of 96.0%. The validity indicator values for screening aspiration were also high, with a sensitivity of 90.0%, specificity of 90.0%, predictive value (+) of 82.0%, predictive value (-) of 95% , 0% and 90.0% accuracy. Conclusion: The method proposed is considered appropriate for oropharyngeal dysphagia and tracheal aspiration screening in patients with Parkinson's Disease.

  • Acoustic analysis of swallowing sounds with the use of Sonar Doppler in premature babies during food transition
    Publication . Vieira Cunha, Talita; Figueiredo, Ana Clara; Guidotti Lemos, Raquel; Pereira, Karina; Zeigelboim, Bianca Simone; Stechman-Neto, José; Sampaio Santos, Rosane
    Objective: To define the acoustic parameters and the feasibility of using swallowing acoustic analysis as an auxiliary method for the transition from nasogastric or orogastric tube feeding to oral breastfeeding. Methodology: A cross-sectional study, which consisted of the following steps: 1. Data collection: Thirty-two newborns participated in this study (16 preterm and 16 full-term); 2. Clinical speech-language pathology evaluation: Clinical data were collected using Sonar Doppler used to assess the readiness of preterm infants to start oral feeding and swallowing sounds. Swallowing sounds were captured during breastfeeding and analyzed according to the frequency, intensity, and time of swallowing, as well as the pause time between swallows and the number of swallows. Results: The control and study groups presented significant differences in the mean wave time and swallowing per minute variables. Conclusion: Sonar Doppler, as an instrument used to capture sounds, is a viable auxiliary resource to evaluate the transition from nasogastric or orogastric tube to oral breastfeeding.

  • Action verbal fluency in Parkinson’s patients
    Publication . Tello Rodrigues, Inês; Ferreira, Joaquim; Coelho, Miguel; Rosa, Mário; Castro-Caldas, Alexandre
    We compared the performance of 31 non-demented Parkinson´s disease (PD) patients to 61 healthy controls in an action verbal fluency task. Semantic and phonemic fluencies, cognitive impairment and behavioural dysfunction were also assessed. The mean disease duration of PD was 9.8 years (standard deviation (SD) = 6.13). There were no age (U = 899.5, p = 0.616), gender(chi-square = 0.00, p = 1.00) or literacy (U = 956, p = 0.96) differences between the two groups. A significant difference was observed between the two groups in the action verbal fluency task (U = 406.5, p < 0.01) that was not found in the other fluency tasks. The education level was the only biographical variable that influenced the action (verb) fluency outcomes, irrespective of disease duration. Our findings suggest a correlation between the disease mechanisms in PD and a specific verb deficit, support the validity of the action (verb) fluency as an executive function measure and suggest that this task provides unique information not captured with traditional executive function tasks.

  • Acupuncture and expression of neurotransmitters in temporomandibular disorders: systematic review
    Publication . Vilela, Maria Cristina; Ramos, Carina; Silva, Hilton Justino
    Temporomandibular disorders (TMD) is a common condition of chronic orofacial pain. Acupuncture is a therapeutic method of traditional Chinese medicine (TCM) and some studies to get understand the mechanisms of action and molecular basis involved in this approach therapeutic. We propose to verify in the current literature on the integration of neurotransmitters expression in treat temporomandibular joint disorders by acupuncture in adulthood. A predefined protocol was used and registered on PROSPERO. This qualitative review of the literature analysed international scientific publications in several databases that used the following keywords: Temporomandibular Joint Disorders OR Acupuncture OR Neurotransmitter. Then, in the study selection phase, the eligible texts were read in full to determine their final inclusion or exclusion. The pre-established selection criteria in the protocol determined the inclusion or exclusion of studies during the selection phase. Although to know the diverse effects of acupuncture are intrinsically linked at the cellular and molecular level there is not yet any paper about this in adulthood, but there is a publication about the relationship between TMD and Acupuncture Treatment. There are no studies in the literature that correlate the temporomandibular disorders, acupuncture therapy and neurotransmitters in humans.
