Abstract
An aspect of the invention providing a method for determining the phase of gait of a subject is provided, the method comprising: transmitting from at least one motion sensor, data corresponding to motion of a part of a lower limb of the subject to a control unit; estimating a gait phase of the subject using the control unit; and sending an input signal based on the estimated gait phase to a controller; based on the input signal, executing a pre-determined instruction or action.
Claims22
A method for determining the phase of gait of a subject, the method comprising:
- transmitting from at least one motion sensor, data corresponding to motion of a part of a lower limb of the subject to a control unit;
- estimating a gait phase of the subject using the control unit;
- and
- sending an input signal based on the estimated gait phase to a controller;
- based on the input signal, executing at least any one of a pre-determined instruction and an action.

A method of estimating gait phase of a subject, the method comprising:
- transmitting from at least one motion sensor to a control unit, data corresponding to motion of a part of a lower limb of the subject to a control unit;
- assigning a phase vector to the data received by the control unit from the at least one motion sensor;
- determining the probability of the phase vector lying within each gait phase of the subject's gait cycle;
- and
- estimating the gait phase of the subject by selecting the gait phase having the highest probability of the phase vector lying therein.
An apparatus for estimating phase of gait of a subject comprising:
- at least one motion sensor associated with the limb of a subject;
- a control unit;
- non-volatile memory;
- and
- communication circuitry,
- wherein, the at least one motion sensor is configured to receive data associated with motion of the limb of the subject, said data being transmitted to the control unit and stored in the non-volatile memory, and wherein external data representative of an action to be undertaken at a predetermined phase of gait is receivable by the communication circuitry and stored in the non-volatile memory,
- wherein the controller is configured to determine the phase of gait from the received data and undertake the action in accordance with the predetermined phase of gait.
