Deanna Kennedy, M.S.Coordinating movements between the limbs is important for many activities of daily living and sport specific skills. Buttoning your shirt, opening a bottle, driving your car, and serving a tennis ball are tasks that involve some type of coordination between the limbs. Although these examples of bimanual movements are relatively easy for most individuals to produce, other more complex coordination patterns have proved to be quite difficult. Bimanual tasks like playing the pian...

Jason Boyle, Ph.DOur nervous system is highly adaptable in perceiving, analyzing and executing movements in relation to an ever-changing perceptual environment. We use vision, knowledge of limb location, and anticipation of force production while simultaneously recognizing variability in our judgment to execute movements through the world around us. Whether it is simple (reaching for a door knob) or complex (threading a needle), goal directed movement has been repeatedly shown to follow a speed/...

Deanna Kennedy, M.S. The ability to coordinate movements between the limbs is important for many activities of daily living and sport specific skills. For example, tying your shoes, slicing bread, driving your car, and serving a tennis ball are tasks that involve some type of coordination between the limbs. However, the role of each limb may vary with different task requirements. Some tasks, such as clapping your hands, require the limbs to produce mirror movements in both time and space. O...

 Jason Boyle, Ph.DOur muscles are controlled by “motor units”, which each consist of a neuron, and the muscle fiber(s) it activates or “innervates”. The muscle that responds is termed an “effector”. Brain mapping studies have shown that a disproportionate area of the motor cortex governs certain effectors of the body. For example, your fingers, lips, and tongue are highly innervated organs that can execute complex movement patterns, but your toes are not ...
