Based on the biological concept of equifinality (i.e., employing different means to achieve the same end state), it can be defined as performing an action or a task in a variety of different ways. To put it another way, it involves using movements in a flexible manner so as to achieve a particular outcome such that there is more than one solution to solve a particular problem. Accordingly, a variety of different muscle contractions and joint rotations can produce the same outcome, something that is not a characteristic of a reflex but rather an action.
