TOR-BSST©

PARA INICIARMOS AS LEITURAS PREPARATÓRIAS PARA OS EVENTOS DESTE ANO NA NOSSA ÁREA, SEGUE BREVE DESCRIÇÃO DO TOR-BSST QUE SERÁ APRESENTADO EM JUNHO/2015 NO CONGRESSO BRASILEIRO DE DISFAGIA PELA DR MARTINO. SEGUE ABAIXO BREVE DESCRIÇÃO EXTRAÍDA DO SITE DA AUTORA E LINK PARA O ARTIGO.

“A primary focus of the lab over the last decade has been the development, validation and implementation of the Toronto Bedside Swallowing Screening Test (TOR-BSST©). Dr. Martino developed the TOR-BSST© to be a tool by which patients can be screened for the presence of swallowing difficulties early in the course of their disease.

The premise of the TOR-BSST© is that earlier identification will initiate earlier intervention, and thereby reduce the incidence of preventable medical complications such as pneumonia, malnutrition and even death while at the same time promote earlier overall recovery. The TOR-BSST© was first validated among stroke patients across the continuum of care and has been distributed to speech language pathologists worldwide. It is currently being translated into several languages and is also undergoing validation among critically ill cardiac patients who have undergone prolonged intubation, thereby ensuring that many more people will benefit from early detection of swallowing problems.”

Congresso Brasileiro de Disfagia

CONGRESSO DISFAGIA
Mais um evento para discutirmos e aprofundarmos os conhecimentos nessa área! O Congresso Brasileiro de Disfagia será realizado em Ribeirão Preto-SP entre os dias 12 e 13 de junho de 2015. Uma série de convidados nacionais e a convidada internacional Dra Rosemary Martino, da Universidade de Toronto, discutirão aspectos relacionados à avaliação da disfagia (como o TOR-BSST), disfagia infantil, mecânica e neurogênica e à pesquisa na área de disfagia.

II Simpósio Nacional IGD de Disfagia

Simpósio IGDComo eu disse no início do ano, 2015 será um convite ao aprimoramento científico, com muitos eventos na nossa área. Este Simpósio será realizado em Porto Alegre-RS, entre os dias 20 e 21 de março de 2015 e está cheio de palestras interessantes e palestrantes com grande expertise na área. Segue o link abaixo para maiores informações (e ainda dá tempo de submeter trabalhos científicos!).

Dysphagia Research Society

Fim do ano chegando e já começamos a nos planejar para 2015! E dentre os planos, a atualização científica deve ser um item com lugar no topo da nossa lista. Nós da disfagia sabemos como é uma área complexa e que requer troca constante. Por isso, hoje a dica é do congresso do Dysphagia Research Society que será realizado em Chicago,em março de 2015! Mas não se preocupem porque muita coisa boa vai acontecer aqui no Brasil também, e nos próximos posts vamos divulgar os eventos da disfagia brasileira, que, por sinal, é super forte e tem se destacado internacionalmente! Um abraço da equipe disfagiabrasil!

Acoustic Study of Pharyngeal Swallowing as a Function of the Volume and Consistency of the Bolus

Dysphagia

August 2014Volume 29, Issue 4, pp 468-474

Abstract

Cervical auscultation is a noninvasive technique for the exploration of swallowing and has been used since the 1960s. The aim of our study was to describe how the volume and consistency of the bolus affect swallowing acoustic sound characteristics in healthy subjects. Twenty-three subjects aged from 20 to 59 years were included (13 women and 10 men). A microphone mounted on a stethoscope chest piece, positioned on the skin on the right side in front of the posteroinferior border of the cricoid cartilage, was used; it was connected to a computer for acoustic recordings. Each subject swallowed 2-, 5-, and 10-ml aliquots of water, yogurt, and mashed potato. Each bolus was administered once, with a period of at least 30 s between each swallow. For each recorded sound, the total duration of the sound and the duration of each sound component (SC) (SC1, SC2, and SC3) and interval (IT1 and IT2) between the SCs were measured. For all records, the average duration of acoustic measures was calculated. Differences according to the volume and the consistency of the swallowed bolus were assessed using Student’s t test for paired data. We calculated the percentage of recordings that included each SC. We also compared results between men and women using Student’s t test. We successfully interpreted 540 of the 621 (87 %) records. The results indicated that the average total duration of the sound, and especially the average duration of SC2, increased with increasing volume and was greater for mashed potato than for the boluses of other consistencies. SC2 was present in all of the records.

Effect of Low-Frequency rTMS and NMES on Subacute Unilateral Hemispheric Stroke With Dysphagia

Lim KB, Lee HJ, Yoo J, Kwon YG.

Ann Rehabil Med. 2014 Oct;38(5):592-602

OBJECTIVE:

To investigate the effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) and neuromuscular electrical stimulation (NMES) on post-stroke dysphagia.

METHODS:

Subacute (<3 months), unilateral hemispheric stroke patients with dysphagia were randomly assigned to the conventional dysphagiatherapy (CDT), rTMS, or NMES groups. In rTMS group, rTMS was performed at 100% resting motor threshold with 1 Hz frequency for 20 minutes per session (5 days per week for 2 weeks). In NMES group, electrical stimulation was applied to the anterior neck for 30 minutes per session (5 days per week for 2 weeks). All three groups were given conventional dysphagia therapy for 4 weeks. We evaluated the functional dysphagia scale (FDS), pharyngeal transit time (PTT), the penetration-aspiration scale (PAS), and the American Speech-Language Hearing Association National Outcomes Measurement System (ASHA NOMS) swallowing scale at baseline, after 2 weeks, and after 4 weeks.

RESULTS:

Forty-seven patients completed the study; 15 in the CDT group, 14 in the rTMS group, and 18 in the NMES group. Mean changes in FDS and PAS for liquid during first 2 weeks in the rTMS and NMES groups were significantly higher than those in the CDT group, but no significant differences were found between the rTMS and NMES group. No significant difference in mean changes of FDS and PAS for semi-solid, PTT, and ASHA NOMS was observed among the three groups.

CONCLUSION:

These results indicated that both low-frequency rTMS and NMES could induce early recovery from dysphagia; therefore, they both could be useful therapeutic options for dysphagic stroke patients.

Chin tuck for prevention of aspiration: effectiveness and appropriate posture

Ra JY, Hyun JK, Ko KR, Lee SJ.

Dysphagia. 2014 Oct;29(5):603-9.

Abstract

Chin tuck has been has been widely used to prevent aspiration in the patients with dysphagia. This study was performed to investigate the effectiveness and the degree of optimal neck flexion of chin tuck. Ninety-seven patients who showed aspiration in the videofluoroscopic swallow study (VFSS). Participants were grouped into the effective (patients who showed effect with chin tuck) and ineffective group (those who did not show effect with chin tuck). VFSS was performed in neutral and chin tuck position and findings were compared between the groups. Severity of aspiration was assessed by the point penetration-aspiration scale. Duration of dysphagic symptoms, history of tracheostomy, and other possible contributing factors were also compared. Neck flexion angle was measured to find appropriate posture in which aspiration was prevented with chin tuck. Aspiration was reduced or eliminated in only 19 patients (19.6 %) with chin tuck. Oral transit time, pharyngeal delayed time and pharyngeal transit time were significantly shortened in both groups (p < 0.05), but the difference between the groups was not significant. Female sex and absence of residue in pyriform sinus favored the effect of chin tuck (p < 0.05). At least 17.5° of neck flexion was required to achieve an effect with chin tuck. The effectiveness of chin tuck was less than anticipated. Patients without residue in pyriform sinus were more likely to benefit from chin tuck. Sufficient neck flexion was important in chin tuck to prevent aspiration.
