A low frequency ultrasonic treatment and monitoring system

In this research, we developed the low-cost equipment applied in the physical treatment of finger-joints. This system can eliminate fatigue of muscle and enhance the healing of hurt tissue with the application of 40 kHz ultrasonic waves. The patients with various conditions can modify the exposed time and periods of ultra sound through a computer for the best curative effect. The system consists of PC-base virtual instrument panel designed by LabView graphic language, transmitting module of ultrasound and electromyogram circuit. Users set the exposed conditions of ultrasound by the virtual panel on the computer screen. Then, commands are connected to the transmitting module of ultrasound via the output channel of PCMCIA card. The EMG of the tissue also are displayed on the panel in real time. Besides, the effect of ultrasonic exposed conditions on EMG was discussed in this article.
