Embodiments of the present disclosure provide a method for measuring a movement of the cervical vertebra, a device thereof and a wearable apparatus. The method for measuring a movement of the cervical vertebra comprises: obtaining a movement angle of the cervical vertebra with a sensor; and calculating a movement amount of the cervical vertebra based on the movement angle of the cervical vertebra. Therefore, according to embodiments of the present disclosure, exact data values of the movement angles of the cervical vertebra can be acquired with the sensor, and the movement amount of the cervical vertebra can be calculated on the basis of this, thereby a quantitative value of the movement of the cervical vertebra can be acquired exactly in form of a numerical value, which is convenient for future processings.
