Large Degrees of Freedom Goal-directed and coordinated movement of body parts is inherently variable because there are many ways of<unk> g body parts to achieve the intended movement goal. This is because the degrees of freedom (DOF) is large for most movements due to the many associated neuro-musculoskeletal elements. Some examples of non-repeatable movements are when pointing or standing up from sitting. Complexity The complexity of<unk>  goes unnoticed in everyday tasks, such as in the task of picking up and pouring a bottle of water into a glass. This seemingly simple task is actually composed of multiple complex tasks. For instance, this task requires the following: (1) properly reaching for the water bottle and then configuring the hand in a way that enables grasping the bottle. (2) applying the correct amount of grip force to grasp the bottle without crushing it. (3)<unk> g the muscles required for lifting and articulating the bottle so that the water can be poured into the glass. (4) terminating the action by placing the empty bottle back on the table. Hand-eye<unk>  is also required in the above task. There is simultaneous<unk>  between hand and eye movement as dictated by the multi-sensory integration of proprioceptive and visual information. Additional levels of<unk>  are required depending on if the person intends to drink from the glass, give it to someone else, or simply put it on a table.
