A method and a monitoring device for optimizing physiological parameter using a motion sensor are provided. The method includes synchronously acquiring a physiological signal and a motion signal of a patient; determining a signal characteristic of the physiological signal from the physiological signal, and determining whether the physiological signal is reliable according to the signal characteristic of the physiological signal; when determining the physiological signal is unreliable, determining a signal characteristic of the motion signal from the motion signal, and determining a motion state during each heartbeat period of a monitored object according to the signal characteristic of the motion signal; according to the motion state during the heartbeat period, determining an effectiveness of the physiological signal during the heartbeat period, or correcting the signal characteristic of the physiological signal during the heartbeat period when calculating physiological parameters, or directly correcting physiological parameters.
