Abstract: Objective:To develop a wearable electro-therapeutic apparatus for chronic soft tissue lesion, which used low frequency electric pulse to treatment the shoulder, back and waist of human body.Methods: The fabric electrodes are fixed on specific position of the elastic vest. The vest elasticity ensures that the electrode and the users are in close contact. MSP430 microcontroller is used as the core of control board. Low frequency pulses for treatment are generated by PWM mode of MSP430 Timer1, then pass through the power amplifier and are added to human body by fabric electrodes. Meanwhile the impedance between electrodes is monitored to avoid the striking fire burns the skin of the human body and ensure user’s safety. The wireless data communication and control between intelligent mobile phone and MSP430 microcontroller are achieved by Bluetooth technology.Results:The developed wearable electrotherapy instrument is easy to operate, safe and reliable, convenient for the daily busy office workers treatment and rehabilitation in working time.Conclusion: It is very fitful for long-term therapy and save the time.
