Dimension and Complexity in Human Movement and Posture.

摘要: There has been considerable effort over the last 25 years to understand emergence of complexity in motor output and how this relates properties individual (e.g., age, disease state, etc.), environment information) task movement, posture, isometric force). This paper addresses behavioral dimension movement posture from a degrees freedom (DF) perspective together with change through aging, fatigue. The behavior for given perceptual-motor is shown be relatively low, dependent on interaction between individual, environmental, constraints varies within limited adaptive range task. determination taken us beyond traditional performance scores but it not sufficient characterization emergent processes complexity.
