Abstract: The present disclosure provides device and method for measuring cervical vertebra movement. The device comprises a sensor unit, a computation unit, a storage unit and a determination unit. The sensor unit comprises at least one transmission part and at least one reception part. Either of the transmission part and the reception part moves along with user's head, the other fixes relative to user's body. The transmission part transmits detection signals and the reception part receives them. The computation unit computes, based on detection signals, distance changes in a distance between the transmitting and reception part before and after user's head moves. The storage unit stores a mapping table indicating relations between distance changes and movement angles of user's head. The determination unit inquires the mapping table based on distance changes to determine movement angles of user's head. The device is simple, easily operated and practicable.
