This paper proposes a basic mechanism of a motion simulator for lower extremities of human in high magnetic field. The motion simulator would provide a wearer with physical supports or physical constrains during walking in a functional magnetic resonance imaging device (fMRI) room so that brain activities during walking could be measured. An fMRI is one of the most powerful tools to measure brain activities but a very simple device attached on a subject for an application of a stimulus was conventionally used in a fMRI room because it constrains a posture of an upper body and limits the use of any magnetic material. This paper shows the compatibility of the motion simulator that consists of Mckibben-type pneumatic artificial muscles and nonmagnetic materials.
