Determining whether an individual has turned during ambulation includes identifying a first foot parameter for the individual in at least two or more successive stances and identifying a change in the first foot parameter between the two or more successive stances. The determination also includes identifying a second foot parameter for the individual in at least two or more successive strides and identifying a change in the second foot parameter between the two or more successive strides. Based on the identified changes in the first and second foot parameters, a determination can be made whether the individual has turned during ambulation.
