A therapeutic device (10) for treating a limb of a human or a non-human animal, comprises an elongate, flexible panel (11), at least one vibrating source in the form of an electric motor (23) driving an eccentric element to produce vibrations at a rate in a range up to 30 Hz, a battery (24) and a control unit (not shown), all being embedded within the elongate, flexible panel (11). As the wiring is embedded within the elongate flexible panel (11) it cannot be interfered with, in use, with the attendant advantages.
