Disclosed is an orthopedic support for securing about the lumbar region of a wearer. The support includes a smoothly contoured body having a template surface bounded by an upper margin and a lower margin. A central trough extends between the upper and lower margins for accommodating the spinal processes of a wearer when the template surface is pressed against the lumbar region. Two raised plateau regions flank the central trough for contacting the erector spinae muscles of the wearer to provide support therefor. The central trough and the plateau regions form a smoothly curving surface approximating the lordotic curve of a wearer to assist maintaining spinal posture. A magnetic pad is attached to the contoured template surface and extends between the margins and extends over the central trough between the two raised plateau regions to provide a therapeutic magnetic field to the lumbar region.
