WebCo-contraction Lumbar spine Trunk muscles Neuromuscular ABSTRACT Background: Many methods exist to describe coactivation between muscles. However, most methods have limited capability in the assessment of coactivation during complex dynamic tasks for multi-muscle systems such as the lumbar spine. WebAdditionally, a co-contraction ratio index (CCR) ... 29 Muscle coactivation is an important component of motor control and joint stability, 30 but excessive coactivation can induce … domain of sine inverse WebHowever, more recent evidence suggests that excitation of Renshaw cells may facilitate antagonist coactivation whereas excitation of Ia inhibitory neurons can induce reciprocal … Webphenomenon of "coactivation"-the weaker contraction of antagonist muscle during the contraction of agonist muscle.-a muscle is activated coordinately with another muscle. A single motor neuron may innervate. a number of muscle fibers. antagonist muscle. domain of sine function WebIn either case a large proportion of spindle responses followed, rather than preceded, activation of the muscle underlying finger movement. Again this supports alpha-gamma … WebJul 1, 2024 · The phenomenon of agonist-antagonist muscle coactivation is discussed with respect to its consequences for movement mechanics … domain of sine function interval notation WebDec 1, 2014 · As already mentioned, coactivation is classically defined as the unintentional concurrent activation of antagonist muscles during the activation of agonist muscles …
