A method is disclosed for enhanced vaccination and genetic vaccination of mammals. The vaccination is accomplished by delivering molecules such as proteins and nucleic acids into skeletal muscle and other cells residing in the skeletal muscle in vivo. The protein or nucleic acid is first injected into the muscle at one or multiple sites. Immediately or shortly after injection, electrodes are placed flanking the injection site and a specific amount of electrical current is passed through the muscle. The electrical current makes the muscle permeable, thus allowing the pharmaceutical drug or nucleic acid to enter the cell. The efficiency of transfer permits robust immune responses using DNA vaccines and produces sufficient secreted proteins for systemic biological activity to be observed.

[Problem to be Solved]The problem to be solved by the present invention is to reduce the load applied to the wearer by correcting a parameter in correspondence with detectivity of biosignals.[Means to Solve Problem]The calibration controlling part 162 of the movement assisting apparatus 10 enables the power amplifying part 158 to apply a driving force of the driving source 140 as a load (input torque) from the load generating part 164 to the wearer 12 when the wearer 12 wears the movement assisting wearing device. Then, the wearer 12 applied with the driving force of the driving source 140 generates power from the skeletal muscles by performing a predetermined calibration operation. Accordingly, the physical phenomenon detecting part 142 detects joint angle along with the calibration operation, and the biosignal detecting part 144 detects myoelectric signals. In the parameter correction part 156, a parameter K is corrected based on the difference between the load (input torque) and the driving force (muscular strength) being calculated by the difference deriving part 154 with respect to the phase identified by the phase identifying part 152.
