“…Terrier and Schutz 2003), as well as in occupational tasks of differing complexity (e.g. Hammarskjo¨ld et al 1989, van Diee¨n et al 2001, Mathiassen et al 2003, Madeleine et al 2008b, Jackson et al 2009). Motor variability is of interest to the engineer to the extent that it may interfere negatively with performance in terms of quality and error rate, even if not all kinematic and kinetic variability will have adverse effects on target performance (Domkin et al 2005).…”

“…Após a análise qualitativa e do RMS, os dados foram submetidos a normalização para obter uma amostra homogênea em que diferenças de procedimentos, como posicionamento de eletrodos e interdindividuais como presença de tecido adiposo, fossem atenuados 33 . As amostras foram submetidas aos critérios de pico máximo e média do sinal eletromiográfico, em que análises estatísticas demonstraram que após a normalização houve diminuição de diferença entre as classes, uma vez que os dados foram suprimidos para a atenuação das diferenças.…”

“…Na eletromiografia cuidados como a normalização, a qual permite que possíveis variabilidades nos procedimentos 32 e diferenças interindividuais entre os sujeitos e grupos possam ser atenuados, devem ser realizados 32,33 . Critérios inerentes ao próprio sujeito nesse caso são utilizados para a obtenção de um perfil homogêneo da amostra 32 .…”

“…Isometric maximal voluntary contraction of the right extensor carpi radialis (ECR), extensor carpi ulnaris (ECU), and extensor digitorum (ED) muscles were registered separately with maximum isometric contraction against manual resistance for 5 s as the subject sat and situated the forearms on the table (Akesson et al 1997). For the trapezius (Trap) muscle, the isometric submaximal reference voluntary contraction approach has been proposed to offer physiologic advantages (Jackson et al 2009). A 15-s submaximal voluntary contraction of the Trap was performed while the right hand of the subject was holding a 1-kg dumbbell with shoulder abduction 90°in the frontal plane, elbow fully extended, and palm side down (Hansson et al 2000).…”
