A new technique for simultaneously recording EMG and movements in experimental animals.
In this protocol a new system is presented for recording EMG signals from leg and trunk muscles along with video-recording of leg and trunk movements. The system comprises a front-end amplifier consisting of a reference amplifier, a differential amplifier with a filter combination and an analog to digital converter (ADC). A fiber optic transmitter connects the front end amplifier via a fiber cable to a receiver board placed in a personal computer (PC). A dedicated software programme (POLY) was written to process the physiological signals on the PC. The physiological recordings can be synchronized to video-recordings and the principles of this technique are given. The system allows to record artifact-free physiological signals and also to link activation patterns in muscles with kinematic aspects of movements.
