“…diculties in controlling muscle force and limb position precisely (Kinoshita and Francis 1996). For example, a larger force variation when trying to keep force constant (Galganski et al 1993), as well as a larger variability between repeated movements, especially when the movements are of small amplitude (Cooke et al 1989) have been found in elderly compared to younger subjects. Such age-related changes could be of signi®cance in performance (Smith et al 1999) and muscle load when carrying out computer tasks.…”

“…The majority of the additional time to complete accuracy-constrained aiming movements is associated with the time after peak velocity, and typically the time between peak deceleration and the end of the movement (Cooke, Brown, & Cunningham, 1989;Darling, Cooke, & Brown, 1989;Goggin & Stelmach, 1990;Welsh, Higgins, & Elliott, 2007). This latter portion of the trajectory is usually associated with target control (Carlton, 1992;Chua & Elliott, 1993).…”

“…Although there is some debate in the literature, it is generally accepted that in aiming or prehension tasks requiring a degree of accuracy and precision older adults take longer to complete their movements than younger adults, display a more asymmetric velocity profile; usually characterised by a lengthened deceleration phase, are more variable, and make more corrective movements at the end (Cooke, Brown and Cunningham 1989;Goggin and Stelmach 1990;Pratt et al 1994;Weir et al 1998). It is also evident that these differences between older and younger adults are exacerbated when task difficulty is increased e.g.…”
