## Abstract

A massage apparatus providing a pulsed electromagnetic field may comprise: a massage unit which comprises a mount frame provided so as to be movable along the body of a user, and an acupressure module protrudingly provided to the mount frame so as to apply pressure to the body of the user; a pulsed electromagnetic field generator which is provided to the mount frame so as to be independent from the acupressure module, and which generates a pulsed electromagnetic field by means of power applied thereto; and a controller which controls the operation of the acupressure module or the generation of the pulsed electromagnetic field. According to such massage apparatus, a pulsed electromagnetic field may be generated by having the pulsed electromagnetic field generator be provided to the massage unit so as to be separate from the acupressure module or air cells performing a massaging operation. In addition, an effect such as body tissue cell activation or damaged cell healing of the pulsed electromagnetic field may be provided when the massaging operation is being performed. Thus, compared to when only a pulsed electromagnetic field is provided without a massaging operation, or when only a continuous electromagnetic field is provided, fatigue of a user may be alleviated, or a disease or illness treatment or prevention effect may be doubled. In addition, since the pulsed electromagnetic field generator is arranged so as to be independent from the acupres sure module or air cells, the range of effects of the electromagnetic field may be expanded so as to include providing a pulsed electromagnetic field to even nearby sites to which pressure is not applied by the acupressure module or air cells, and since the pulsed electromagnetic field generator may be independently detached or replaced, costs for managing the massage apparatus may be reduced.
