Abstract

In one aspect, a method of detecting a step taken by a patient with a walking aid is disclosed. At least one load sensor detects a transitory positive load upon the walking aid having a maximum load value that exceeds a positive load threshold. A duration of the transitory positive load is measured. A verification is made that the measured duration of the transitory positive load upon falls within a range. The load sensor(s) and a motion sensor further detect an unweighted movement of the walking aid exceeding a movement threshold. A duration of the unweighted movement is measured. A further verification is made that the duration of the unweighted movement of the walking aid exceeds a minimum recovery phase duration threshold. Conditionally upon the detecting, the verifying, the further detecting, and the further verifying, an indicator of the step is stored in a non-transitory memory.
