Relationship between Isometric Muscle Force and Fractal Dimension of Surface Electromyogram

Table 1

Results of the reliability analysis of initial values of CV, FD, MNF, and ARV at 10 to 90% MVC. Intra- and intersession ICC scores are reported.

Note. MVC: maximal voluntary contraction; ICC: intraclass correlation coefficient intra- and intersession.
