A repositioning device and a garment (101), to be used in daily activities or exercise, correct ones posture to a proper ideal one and create superior body balance. A posture molding method and a training instruction method utilize the repositioning device and the garment. The repositioning device contains a vibration generator inside a case. From the vibration generator, vibratory stimulation is provided to the skin on a human body surface, thereby promoting neurotransmission in muscles. The garment (101) is equipped with point stimulation parts (10a) and/or surface stimulation parts (10b) for promoting facilitation and inhibition of neurotransmission in muscles, respectively. In molding a posture or giving training instructions, a practitioner/trainer utilizes the repositioning device and the garment (101) to facilitate and/or inhibit neurotransmission in muscles.
