Six subjects between the ages of 18 and 35 years old were examined to compare muscle use. The rectus abdominus, erector spinal, gluteus maximus, quadriceps, hamstring, gastrocnemius, and tibiallis anterior muscles were assessed by electromyogram. Conventional exercise was performed by weight lifting on quadriceps, hamstring, abdominal and back extension machines and then compared to low-impact ...

Conventional methodology for examining conditioned fear has involved visual-based technologies such as cameras and direct observation. These methods are excellent screening tools of fear behavior (i.e. freezing). However, they do not provide a physiological output, which could be useful to examine neurophysiological correlates of fear. We found that dorsal neck electromyography can be used as a...

Electrical signals recorded from muscles require processing before its use, so the modeling of these bioelectric signals is necessary. Wavelets are used for the processing of signals that are non-stationary and time varying. The surface Electromyogram signals were estimated with following steps, first, the obtained signal was decomposed using wavelet transform; then, decomposed coefficients wer...
