Introdução: As disfunções do CAO são muito frequentes na prática clinica. Devido à
sua natureza multifactorial, muitas têm sido as propostas de intervenção em fisioterapia para
esta condição clínica. No entanto reconhece-se que a utilização do tape McConnell é uma das
estratégias mais utilizadas.
Objetivo: Avaliar os efeitos do Tape McConnell na atividade muscular do TS e TI e
cinemática 3D do CAO, em sujeitos saudáveis, durante a realização de duas atividades
funcionais de elevação do membro superior.
Metodologia: Realizou-se um estudo metodológico observacional descritivo. A amostra
(n=22) é não probabilística por conveniência e teve origem na população de estudantes da
ESS-IPS. O instrumento de medida foi um sistema 3D de captura de movimento. Foram
avaliadas as variáveis de intensidade de contração e instantes de ativação do TS e TI e
cinemática da ET e GH. Para a análise dos dados recorreu-se à estatística descritiva e
inferencial.
Resultados: Ao nível do EMG encontraram-se efeitos na aplicação do tape tanto na
intensidade de contração do TS como do TI, sendo que esta aumentou e diminui,
respectivamente com a aplicação. Apenas para a atividade balística, na intensidade do TS, não
se verificaram efeitos estatísticos. Não se verificaram alterações nos instantes de ativação de
nenhum dos músculos estudados. Na cinemática da ET, verificaram-se efeitos ao nível da
báscula anterior da omoplata, que aumentou em ambas as atividades. Na cinemática da GH,
verificaram-se resultados significativos, e melhoria das amplitudes em todos os movimentos
considerados, excepto na elevação durante a atividade balística.
Conclusão: Este estudo vem demonstrar que o tape, embora tenha efeitos ao nível da
cinemática da ET e da GH, melhorando o desempenho e o REU, a sua forma de atuação
pode ser diferente do que está pressuposto, pelo menos em sujeitos assintomáticos. Após este
estudo questiona-se os pressupostos que muitos autores atribuem ao tape, visto que se estes se
verificassem tal como são considerados, seria de esperar resultados diferentes dos obtidos
neste estudo. A realização deste estudo permitiu compreender o comportamento do tape num
espectro de normalidade, que poderá servir de base a estudos futuros.
Abstract:Background: The dysfunctions of the shoulder complex are frequent and limiting. The choice of an effective treatment is difficult due to the multifactorial nature of the condition. However, there is a focus on the treatment to be directed to the replacement of the mechanisms of dynamic stability, with special attention to the TS and IT muscles. Tape may therefore act as a supplement promoting motor control. Objectives: To evaluate the effects of Shoulder McConnell taping on the surface electromyographic signal of trapezius muscle and 3D shoulder kinematics, during two upper limb functional tasks Methodology: We conducted a descriptive observational study methodology. The sample (n = 22) is non-probabilistic convenience and originated in the student population of ESS-IPS. The measurement instrument was a 3D movement capture system. The variables of intensity and onset of upper (UT) end lower trapezius (LT) and kinematics of ET and GH were evaluated. To analyze the data, we used the descriptive and inferential statistics. Results: For the EMG effects, we found that the contraction intensity of UT and LT, increased and decreased, respectively with the application of the tape. Just for the ballistic activity, in contraction intensity of UT, there were no statistical effects. There are no statistical effects on onsets. In kinematics of ET, there were effects at anterior tilt movement, which increased in both activities. About kinematics of GH, there were significant results, and improvement in all range of movements, except in elevation, during ballistic activity. Conclusions: This study demonstrates that tape, although effects on the kinematics of ET and GH, improving performance and REU, its mechanisms may be different from what is assumed, at least in asymptomatic subjects. After this study, we question the assumptions that many authors attribute to tape, as if these occur how is considered, we would expect different results. This study allows us to understand the behavior of tape in a normal range, which may serve as a basis for future studies.
