Abstract
In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.
