Abstract
Methods and systems may provide for a plurality of kinematic sensors to be coupled to a corresponding plurality of shanks of an individual, a processor, and a memory to store a set of instructions. If executed by the processor, the instructions can cause the system to calculate a timed up and go (TUG) time segment based on angular velocity data from the plurality of kinematic sensors. The instructions may also cause the system to calculate a derived parameter based on the angular velocity data, and generate a falls risk assessment based on at least one of the TUG time segment and the derived parameter.
Claims22
1-20. (canceled)
A system comprising:
- a plurality of shank-mounted kinematic sensors;
- a processor;
- and
- a memory to store a set of instructions which, when executed by the processor, cause the system to:
- obtain a plurality of adaptive thresholds whose values change based on angular velocity data from the plurality of kinematic sensors, wherein the plurality of adaptive thresholds defines a likely range of a plurality of heel-strikes and toe-off points in the angular velocity data.
A method comprising:
- obtaining a plurality of adaptive thresholds whose values change based on angular velocity data from a plurality of shank-mounted kinematic sensors, wherein the plurality of adaptive thresholds defines a likely range of a plurality of heel-strikes and toe-off points in the angular velocity data.
A non-transitory computer readable storage medium comprising a set of instructions which, if executed by a processor, cause a computer to
- obtain a plurality of adaptive thresholds whose values change based on angular velocity data from a plurality of shank-mounted kinematic sensors, wherein the plurality of adaptive thresholds defines a likely range of a plurality of heel-strikes and toe-off points in the angular velocity data.
