The pressure sensor can directly contact the foot, which can easily cause pain. [Solution] When the subtalar joint, navicular bone, and medial cuneiform bone area move, the membrane 37 is pushed inward into the main body 35, and the air inside the main body 35 moves to the relief section 34 via the hose 32. The air flow rate at this time is acquired by the flow sensor 33. The output signal of the flow sensor 33 is transmitted from the sensor board 4 to the computer 5. The pronation measurement unit 3 acquires from the output signal of the flow sensor 33 where and to what extent pronation movement is occurring. The judgment unit 52 calculates and outputs the pronation movement and the COP of the foot based on these measurement results. The measurement results are generated in real time. The subject refers to these measurement results and performs correction through effort walking.
