Injuries to the lower extremity can limit joint motion and alter movement patterns of the limb segments during gait. Researchers have also found changes in variability and complexity as a function of injury. Injury or joint pain appears to decrease gait cycle variability ; however, the results on complexity are less clear. While some researchers have found a decrease in complexity due to disease and aging, e.g., , others have found an increase in complexity . One of the goals of the current work was to quantify changes in the variability and complexity of motion patterns as assessed using phase portraits.
