A therapeutic device for treating a limb of a human or a non-human animal, has an elongate, flexible panel, at least one vibrating source in the form of an electric motor driving an eccentric element to produce vibrations at a rate in a range up to 30 Hz, a battery and a control unit, all being embedded within the elongate, flexible panel, and connected together by wiring (not shown), which wiring is also embedded within the elongate, flexible panel. As the wiring is embedded within the elongate flexible panel it cannot be interfered with, in use, with the attendant advantages.
