- ItemSomente MetadadadosEstimativa do número de unidades motoras em voluntários normais e sua reprodutibilidade utilizando a técnica da estimulação em múltiplos pontos(Universidade Federal de São Paulo (UNIFESP), 2014-12-31) Azevedo, Lyamara Apostolico de [UNIFESP]; Manzano, Gilberto Mastrocola Manzano [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: Motor unit number estimation (MUNE) is a clinical neurophysiologic technique used to estimate the number functional motor neurons or motor axons innervating a muscle and provides quantitative information on the size of individual motor units. It is of clinical interest to quantify motor unit or axon loss over time, monitor the clinical course and evaluate the efficacy of treatment of neuromuscular diseases. MUNE is calculated by dividing the compound muscle action potential (CMAP) amplitude or area by the mean amplitude or area of individual surface motor unit potencials (S-MUPs). Objective: Evaluate the MUNE calculation parameters, collect MUNE normative data and assess reproducibility in healthy volunteers, using multiple point stimulation technique (MPS). Methods: We estudied 114 healthy volunteers (mean age 38.5±15.73) in two groups divided by age: 18 to 59 years (100) and 60 years or older (14). MUNE was calculated in the right median innervated tenar eminence. In 30 subjects, the protocol was performed twice by the same examiner to evaluate reproducibility. Results and Conclusions: Mean MUNE values among subjects aged 18 to 59, based on three alternative metrics: negative peak amplitude, peak-to-peak amplitude and negative peak area, were 282.6 (±62.6), 296.7 (±71.9) and 307.4 (±73.7), respectively, and among subjects aged 60 years or older were 216.4 (±54.6), 216.4 (±61.5) and 212.2 (±57.3), respectively. MUNE values based on the three metrics differed significantly. Reductions by 27% in MUNE among older subjects were accompanied by increases by less than 1% in mean S-MUP, reductions by 27% in the CMAP and increases in the frequency of larger S-MUPs. Reproducibility, based on three alternative metrics (negative peak amplitude, peak-to-peak amplitude and negative peak area), was high for CMAP (ICC=0.81, 0.82 and 0.76, respectively), moderate for MUNE (ICC=0.53, 0.54 and 0.51, respectively) and poor for mean S-MUP (ICC=0.09, 0.26 and 0.26, respectively).
- ItemSomente MetadadadosTradução e adaptação cultural da escala de qualidade de vida no AVE “SIS” Stroke Impact Scale 20(Universidade Federal de São Paulo (UNIFESP), 2015-06-30) Brandao, Aline Dias [UNIFESP]; Gazzotti, Mariana Rodrigues Gazzotti [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: There are today few specific scale to measure the quality of life of Cerebral Vascular Accident (CVA) patients; and none of these questionnaires have been translated into the Portuguese language or had their reliability assessed. The Stroke Impact Scale (SIS) is available in the international literature as a tool to analyze the overall impact of light and moderate CVA on the patients? daily living. Objective: Translate the SIS ? Stroke Impact Scale 2.0 into the Portuguese language (Brazilian Portuguese), carry out cross-cultural adaptation and assess its reliability. Correlate SIS 2.0 with the SF-36 and with HADS (Hospital Anxiety and Depression Scale) in CVA patients. Methods: The process of translation and back-translation was carried out, along with adaptation to the Portuguese language and Brazilian culture. In order to assess the reliability of the scale, it was applied on 40 CVA patients from the Neurovascular outpatient clinic, who answered the questions for three times. On the first day, the scale was applied twice by two independent researchers (interobserver reproducibility); and after 15 days the scale was applied or the third time by researcher 1 (intraobserver reproducibility). The intraclass correlation coefficient (ICC) was used to test the reliability of the SIS 2.0 scale. Results: The reliability of the scale was very good (ICC: 0.73 to 0.99). The intraobserver reliability was also very good for all domains (ICC = 0.85 to 0.95). Correlating SIS 2.0 with SF-36, for the domains strength, mobility; ADL and functional capacity, and ADL correlated with general health conditions, the correlations were moderate. For all other domains the correlations were weak. Moderate negative correlation was observed between depression and the domains memory and communication. Conclusion: The version of SIS 2.0 translated into Portuguese and adapted to the Brazilian culture proved to be patient-friendly and presented good reliability to be used with patients diagnosed with CVA.
- ItemAcesso aberto (Open Access)Versão brasileira do Dynamic Gait Index(ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2006-12-01) De Castro, Sandra Meirelles; Perracini, Monica Rodrigues [UNIFESP]; Ganança, Fernando Freitas [UNIFESP]; UNIBAN; Universidade Federal de São Paulo (UNIFESP); Universidade Cidade de São PauloThe Dynamic Gait Index (DGI) is a useful test to evaluate balance and gait. AIMS: The objectives of this study were to culturally adjust the DGI to the Portuguese language and to assess its reliability. METHODS: The method proposed by Guillemin et al. (1993) was used for a cultural adaptation of this tool. A prospective study was performed with 46 patients that were assessed in the cultural adaptation phase. The items that not understood by 20% or more patients were reworded and reapplied. The final Portuguese version of DGI was applied to 35 elderly in order to check intra and interobserver reliability. The Spearman rank coefficient was used to correlate intra and interobserver scores and the Wilcoxon test was applied to compare these scores. Internal consistency was analyzed by the Cronbach alpha coefficient. RESULTS: There were statistically significant correlations among the scores for intra and interobserver assessments for all items (p<0.001), which were classified as good and very strong correlations (ranging from r=0.655 to r=0.951). The DGI demonstrated high internal consistency in intra and interobserver assessments (varying from µ or = 0.820 to µ or = 0.894). CONCLUSION: The DGI was culturally adjusted to Brazilian Portuguese and proved to be a reliable tool.
