“…2d–f). Slower, more-variable and more-extraneous movements are observed in the paretic forelimb of rodents after motor system damage than in intact animals 65,67,68 . To reach for food rewards with the paretic forelimb, rodents use compensatory rotational movements of the trunk to extend and control paw position, and use compensatory trunk and head movements to bring the mouth to the paw 16,63,69 .…”

“…The strategies of relying mostly on the non-paretic hand and of relying on proximal body movements instead of distal arm movements can encourage the disuse of any residual capacity for a greater range of paretic limb movements that might be achieved with practice to enable better overall functionality 47,67,142 . Such forms of compensation could be the best option for those with the most-severe impairments; for those with milder impairments, however, they are unlikely to be.…”

“…Compensatory use of the proximal musculature is also commonly observed in humans after stroke (Cirstea and Levin, 2000). Functional outcomes improve over time, but true recovery may be masked (Whishaw, 2000;Whishaw et al, 1991), or even hindered (Alaverdashvili et al, 2007(Alaverdashvili et al, , 2008, by the use of alternative movement strategies (Levin et al, 2009). …”

“…Once a bias to produce a particular outcome is in place, that bias can be very difficult to change, even when it is less efficient than alternatives that are physically possible to produce. For example, once certain aspects of reaching in rats become habitual, they can persist even when they produce a lower success rate in retrieving food items than an alternative combination of movements (Alaverdashvili, Foroud, Lim, & Whishaw, 2008). The same may apply to phylogenetically biased movement patterns (Berthoz, 2000;Llinás, 2001).…”
