The invention discloses a sound-light-electricity rhythm physiotherapy instrument. The physiotherapy instrument comprises a physiotherapy electrode, a battery and a light-emitting diode, and further comprises a suction cup, a piezoelectric flat speaker, a sound-light-electricity control circuit, a rhythm generator and a rhythm control key, wherein the battery is connected with the rhythm generator and the sound-light-electricity control circuit; the rhythm generator is connected with the rhythm control key and the sound-light-electricity control circuit; the sound-light-electricity control circuit is connected with the light-emitting diode, the piezoelectric flat speaker and the physiotherapy electrode; and the electrode, the speaker and the light-emitting diode are arranged on the suction cup. The electrode, the speaker and the light-emitting diode are skillfully combined and fixed to the skin through the suction cup, so that sound-light-electricity physical factors synchronous with music rhythms can effectively act on a human body to generate brand-new rhythm stimulation; and the rhythm stimulation can enable the muscles, nerves, body fluids, blood and the like of the human body to produce physicochemical reactions, so that the effects of effectively relieving pain, diminishing inflammation, removing swelling, regulating the nerves and eliminating fatigue can be achieved.
