Improved human body balance function detection method and training system

The invention discloses an improved human body balance function detection method and training system, and relates to the field of medical equipment. According to the invention, monitoring on myoelectricity, measurement of the center of gravity based on an acceleration sensor and a falling-down detection method are applied to balance function detection and rehabilitation function training, the defect that the test index of an existing balancing instrument is single is corrected, and therefore comprehensive and accurate detection on the human body balance function and more scientific rehabilitation function training are achieved. The training system comprises a human body myoelectricity and acceleration detection module, a human body balance pressure signal detection device, a centre-of-gravity position real-time display, a balance function liquid crystal display screen and balance function monitoring software based on a computer. The human body myoelectricity and acceleration detection module comprises a myoelectricity amplification circuit, a three-axis acceleration sensor, a signal processing circuit, a data acquisition circuit and a radio communication circuit. The human body myoelectricity and acceleration detection module fixed on the back waist position carries out data transmission with the computer through a wireless transmission module. The balance function monitoring software based on the computer processes, analyzes, stores and replays myoelectric signals, acceleration signals and pressure signals, and detects and gives alarms to falling-down events in real time.
