Abstract
Apparatus and method for providing PEMF therapy to selected portions of a patient's body such as the hips and spine. The apparatus preferably includes at least two transducer coils. Electronics for driving the coils are contained in a housing. The housing is preferably connected to the transducer coil by a flexible cable. The housing preferably includes a battery power supply.
Claims30
An apparatus for providing electromagnetic therapy to a patient comprising:
- a housing containing an electrical circuit for generating an electrical drive signal;
- a first transducer coil and a second transducer coil for generating respective electromagnetic fields in response to the drive signal;
- a first portion with a configuration corresponding generally with a chair seat and a second portion with a configuration corresponding generally with a chair back, the first transducer coil disposed within the first portion and the second transducer coil disposed within the second portion;
- a flexible cable adapted to connect the electrical drive signal with the first transducer coil and the second transducer coil;
- and
- the first and second transducer coils being adapted to cooperate with each other to produce a pulsed electromagnetic field having a plurality of pulses in response to the electrical drive signal, each pulse having a pulse period of ten microseconds to twenty microseconds.
