The invention relates to the technical field of physiotherapy, and provides a liquid metal-based wearable physiotherapy instrument. The liquid metal-based wearable physiotherapy instrument comprises athermal therapy unit; the thermal therapy unit comprises a heat conduction layer and electric heating elements; the heat conduction layer comprises a first flexible accommodating body and a heat conduction material filled in the first flexible accommodating body; the heat conduction material adopts the liquid metal at a room temperature; and the electric heating elements are in contact with the heat conduction material. According to the liquid metal-based wearable physiotherapy instrument in the scheme, by virtue of high fluidity and high heat conductivity of the liquid metal, heating uniformity can be ensured and quick heating and warm keeping can be realized, thereby improving partial tissue temperature, accelerating blood circulation, relieving muscular tension and muscular soreness, and even improving sleeping quality and relieving tension emotion; and in addition, the wearable physiotherapy instrument can be set into the shapes of gloves, foot sheaths or head sheaths so as to becarried conveniently.
