The invention relates to a device for measuring and teaching human position and/or movement, comprising an actuator, specifically a motor-gear assembly, a sensor for measuring a change of the human position and/or movement in at least one joint area, and a control unit for storing the position and/or movement changes measured by the sensor and for controlling the actuator. The device comprises a power supply for operating the actuator, a tensioning mechanism, which is attachable to human skin, linked to the actuator and operated by the actuator, and which communicates to the skin a correction-oriented tensioning stimulus.
