A thermostimulation system and method. The inventive thermostimulation system is adapted for use with a console for providing electrical currents for thermal and electrical stimulation in response to a first input from an operator via at least one electrical connector. Generally, the inventive thermostimulation system includes at least one inline control system coupled to the console via electrical connector for regulating the currents to an associated thermostimulation pad via a second connector. The pad has a temperature sensor adapted to provide a feedback signal to the inline control system. In more specific embodiments, plural pads and inline control systems are connected to the console. Each inline control system has a first microprocessor for providing heat and stimulation current control for the pad and a second microprocessor for providing overcurrent safety control for the pad. Each inline control system has a display and a patient over-temperature control switch. Each pad has a connector integrated multilayer construction with a heating element implemented with a wire matrix and slots for flexibility. In addition to a temperature sensor, each pad also includes two electrical stimulation contacts having a wire conductor along the length thereof. Each pad is connected to an associated inline control system via a flat connector. Specially designed strain relief grommets are provided on both ends of the flat cable.L'invention concerne un système et un procédé de thermostimulation.
