| Outline of Final Research Achievements |
The aim of the study was to examine the temporal correlation between rectified EMG and instantaneous MU discharge rate in low frequencies. Healthy young subjects produced steady submaximal force with their right finger. Surface EMG and fine-wire MU potentials were recorded from the first dorsal interosseous muscle in the right hand. Rectified surface EMG and the instantaneous discharge frequency of MUs were smoothed by a Hann-window of 400 ms duration. In each of the identified MUs, the smoothed MU discharge frequency was positively and temporally correlated with the rectified-and-smoothed EMG as confirmed by the distinct peak in cross correlation function. The results indicated that the low-frequency component of rectified surface EMG provide temporal information on the low-frequency oscillations in the MU discharge frequency.
