Comparison of knee mechanics among risky athletic motions for noncontact anterior cruciate ligament injury.

abstract：:We tested the ability of healthy elderly persons to use anticipatory synergy adjustments (ASAs) prior to a self-triggered perturbation of one of the fingers during a multifinger force production task. An index of a force-stabilizing synergy was computed reflecting covariation of commands to fingers. The subjects produ...
