“…The reduction of the P-P of RM trajectory in the anteroposterior direction reflects a higher efficiency of the postural control system (Bennell & Goldie, 1994;Kinzey, et al, 1997;Norris, et al, 2005;Prieto, et al, 1996) related to supraspinal processes that define an instantaneous point about which the body is stabilised (Zatsiorsky & Duarte, 1999. The increased MV of the RM component could be related to a reweighted combination of reciprocal activation and co-activation commands (Drew & Rossignol, 1987;Feldman, 1980aFeldman, , 1980bFeldman & Levin, 1995;Lacquaniti, 1992;Lacquaniti et al, 1991;Levin et al, 1992).…”
