1. A device for supporting a lower limb of a subject, comprising:
a housing for a lower limb, the housing having a longitudinal axis configured to be aligned with a longitudinal axis of the lower limb, in use;
a limb support comprising an elongated bracing member;
a driving mechanism connected between the housing and the limb support, the driving mechanism comprising a first part attached to the housing and a second part connected to the limb support; and
an actuator configured to be located at or near a knee of the subject wearing the device and connected to the driving mechanism for enabling the subject to operate the driving mechanism,
wherein, in use, actuation of the driving mechanism drives a movement of the limb support between a retracted position parallel to the longitudinal axis of the housing and an extended position in which the limb support extends perpendicularly to the longitudinal axis of the housing to support the lower limb, and
wherein in the extended position, the limb support is adapted to extend between the housing and the ground to support the lower limb above the ground.
