Abstract: A device for functional electrical stimulation, including a garment mountable on a user's body part, an assembly having a socket and an electrode in turn having electrode pads and a stimulator with a controlling mechanism for activating/deactivating stimulating electrical signals to be provided to at least some of the electrode pads. The garment defines a hollow area configured to receive the socket, the socket configured to house the stimulator. In use of the device, a first portion of the electrode is in contact with an inner surface of the garment, the electrode pads are in a fixed position with respect to the garment, and a second portion of the electrode is in contact with a surface of the socket for receiving the stimulating electrical signals delivered by the stimulator. A system may include the device and a sensor configured to be positioned on either user or in proximity thereto.
