Abstract
A method for determining postural stability of a person can include acquiring a plurality of pressure data points over a period of time from at least one pressure sensor. The method can also include the step of identifying a postural state for each pressure data point to generate a plurality of postural states. The method can include the step of determining a postural state of the person at a point in time based on at least the plurality of postural states.
Claims23
A computer-implemented method for determining postural stability of a person, the method comprising:
- acquiring, by a processor, a plurality of pressure data points over a period of time from at least one pressure sensor;
- identifying, by the processor, a postural state for each pressure data point to generate a plurality of postural states;
- and
- determining, by the processor, a postural state of the person at a point in time based on at least the plurality of postural states and a probability of transitioning between at least one of the plurality of postural states and another postural state, wherein the postural state is at least one of a static postural state or a dynamic postural state.
A computer-implemented method for determining postural stability, the method comprising:
- acquiring, by a processor, at least a first pressure data point and a second pressure data point from at least one pressure sensor;
- identifying, by the processor, a first postural state and a second postural state based on the first and second pressure data points, wherein identifying comprises identifying the first postural state as static or dynamic and the second postural state as static or dynamic;
- and
- determining, by the processor, a postural state at a point in time based on at least the first postural state, the second postural state, and a probability of transitioning between at least one of the first or second postural states and another postural state.
A system for determining postural stability of a person comprising:
- at least one pressure sensor coupled to the person that acquires a plurality of pressure data points over a period of time;
- means for identifying a postural state for each pressure data point;
- means for generating a plurality of postural states of the person over the period of time;
- and
- means for determining a postural state of the person at a point in time based on the plurality of postural states and a probability of transitioning between at least one of the plurality of postural states and another postural state, wherein the postural state of the person is one of a static postural state or a dynamic postural state.
