Abstract: Apparatus (30) for detecting motion of a device (1) for electrical stimulation of a subject is described. The apparatus (30) comprises a motion detector (2) to detect the motion of the device (1) and generate a motion output signal in response to the detected motion. The motion output signal is indicative of the amount of detected motion. A processor (21) is coupled to the motion detector (20). The processor (21) receives (72) the motion output signal from the motion detector (20) and generates a first processor output signal in response to the received motion output signal. An output device (14, 26) is coupled to the processor (21). The output device (14, 26) receives the first processor output signal from the processor (21) and generates a first output signal in response to the received first processor output signal.
