Abstract
A collar (100) for providing PEMF therapy for the cervical region of the spine. The collar (100) has a single transducer coil (104) and requires no secondary coil. The electronics for driving the coil are contained in a housing (101) that is integral to the collar 100. The housing (101) may also contain a battery for powering the coil (104), whose power usage is sufficiently reduced so as to require only a small battery.
