Step counting and motion state evaluation device

The invention discloses a step counting and motion state evaluation device. According to the step counting and motion state evaluation device, motion posture characteristics are acquired by using a motion sensor, muscle activity levels are acquired by using a multi-channel surface myoelectricity sensor, and with the combination of the motion posture and the muscle activity degree, the steps in different motion modes can be counted, and the calorie consumption can be calculated. With the combination of a surface myoelectricity pedometer and an analysis device, the step counting and motion state evaluation device is relatively professional when being compared with a conventional pedometer, relatively rich muscle physiological information can be provided, and the step counting and motion state evaluation device is particularly applicable to motion and rehabilitation evaluation.
