A therapeutic device. The therapeutic device includes a first vibration contact configured to be in mechanical communication with a first location of the body of a subject. A first vibrator is connected to the first vibration contact and configured to cause a first vibration at the first vibration contact. A second vibration contact is configured to be in mechanical communication with a second location of the body of the subject. A second vibrator is connected to the second vibration contact and configured to cause a second vibration at the second vibration contact. The second vibration has a different frequency than the first vibration resulting in a low frequency, inferential, traveling wave within the subject that propagates to the subject's head.

A percussive therapy device includes a housing, a motor, a reciprocation shaft coupled to the motor and configured to reciprocate when the motor is active, an infrared radiation emitter contained in the housing, and a fan. The housing includes a window including a surface. The fan is configured to direct air along an air flow path, and a portion of the air flow path extends along the surface of the window.

A therapeutic system includes a device and an attachment for the device. The device comprises an electrical power source and a mount. The attachment can be removably coupled to the mount. The therapeutic system also includes a first electrical connector comprising a socket and a second electrical connector comprising prongs configured to fit the socket. The attachment includes either the first or the second electrical connector, and the mount includes the other of the first or the second electrical connector. The electrical connector comprised by the mount is electrically connected to the power source.
