ABSTRACT
PURPOSE: Aphasia is a common and debilitating manifestation of stroke. Transcranial electrical stimulation uses low-intensity electric currents to induce changes in neuronal activity. Recent evidence suggests that noninvasive techniques can be a valuable rehabilitation tool for patients with aphasia. However, it is difficult to recruit patients with aphasia for trials, and the reasons for this are not well understood. This study aimed to elucidate the main difficulties involved in patient's recruitment and inclusion in a randomized clinical study of neuromodulation in aphasia. METHODS: We evaluated the reasons for the exclusion of patients in a pilot, randomized, double-blinded clinical trial in which patients diagnosed with motor aphasia after stroke were recruited from March to November 2018. A descriptive statistical analysis was performed. RESULTS: Only 12.9% (4) of patients with ischemic stroke were included in the clinical trial. A total of 87.1% (27) of the 31 recruited patients were excluded for various reasons including: sensory aphasia (32.2%), dysarthria (25.8%), spontaneous clinical recovery (16.1%), previous stroke (6.4%), and death or mutism (3.2%). CONCLUSION: The presence of other types of aphasia, dysarthria, spontaneous recovery, deaths, and mutism were barriers to recruiting patients evidenced in this neuromodulation study.

RESUMO Objetivo Verificar os resultados de inteligibilidade da fala de pacientes submetidos à palatoplastia primária, de acordo com o julgamento perceptivo de cinco examinadores, experientes ou não, no tratamento de fissuras labiopalatinas. Métodos Foram analisados os registros de fala espontânea, armazenados em sistema audiovisual, de 78 pacientes com fissura labiopalatina previamente reparada, de ambos os gêneros, a partir de 4 anos de idade, submetidos à palatoplastia primária. As amostras de fala foram analisadas por cinco diferentes examinadores, que classificaram a inteligibilidade de fala utilizando uma escala de 3 pontos (1=boa, 2=regular e 3=ruim). A concordância interexaminadores foi verificada por meio do coeficiente de Kappa. O sucesso da reabilitação foi analisado descritivamente quanto às proporções de pacientes, de acordo com o grau de inteligibilidade pós-operatória, determinada pelos examinadores. A significância entre as diferenças das proporções obtidas para cada categoria foi verificada pelo teste Qui-quadrado (p<0,05). Resultados A concordância entre os examinadores variou de discreta a substancial. Em mais da metade das amostras os examinadores obtiveram concordância plena. Com base nos valores médios dos julgamentos dos avaliadores, uma proporção significativa dos casos apresentou boa inteligibilidade de fala. Conclusão Verificou-se adequação da inteligibilidade de fala após a palatoplastia primária, na maioria dos casos estudados, sugerindo, assim, que esses pacientes são bem compreendidos em seu meio social. A experiência do avaliador mostrou-se uma variável importante na análise.
ABSTRACT Purpose To verify the results of speech intelligibility in individuals submitted to primary palatoplasty, according to perceptual analysis by five examiners, experienced or not with the treatment of cleft lip and palate. Methods Analysis of spontaneous speech records, registered in audiovisual system, of 78 individuals with repaired cleft lip and palate, of both genders, aged more than 4 years old, submitted to primary palatoplasty. The speech samples were analyzed by five different examiners, who scored the speech intelligibility using a three-point scale (1=good, 2=regular, and 3=bad). The interexaminer agreement was assessed by the Kappa coefficient. The treatment success was analyzed descriptively regarding the proportion of patients according to the postoperative speech intelligibility, as determined by the examiners. Significance between differences was verified by the chi-square test (p<0.05). Results The interexaminer agreement ranged from fair to substantial. Full agreement between the five examiners was observed in more than half of cases. Based on the mean values assigned by the examiners, a significant proportion of cases showed good speech intelligibility after palatoplasty. Conclusion The present outcomes evidenced adequate speech intelligibility after primary palatoplasty in the majority of cases, suggesting that these individuals are well understood in their social environment. The examiner experience presented to be an important variable in the analysis.
