The present invention relates to a health care network system and a method thereof utilizing a smart communicator. A portion of an input signal of the optical device and a portion of an output signal from the optical device are coupled to an optical processing unit and a an optical to electrical signal converter. The assembly forms an active electro-optical device that can be driven efficiently. A stepping motor is used as the driver. A method for the treatment or prevention of musculoskeletal indications comprising providing a top plate, providing a base plate, generating a first magnetic field to levitate the top plate, generating a second magnetic field to drive the top plate into vibration, adjusting frequency of vibration of the top plate; and adjusting magnitude of vibration of the top plate.
