NEW INTERPRETATION ON EMG CHARATERISTICS OF SPASTIC CEREBRAL PALSY DURING A REHABILITATIVE WALKING EXERCISE
Keywords: electromyography, spastic cerebral pal'sy, power spectrum analysis
AbstractThe purpose of this study is to interpret the EMG characteristics of spastic cerebral palsy children during walking with power spectrum analysis. The EMG signal of 16 cerebral palsy patients (GP) and 18 age matched control (Normal) were collected during several walking trial. It was found that our CP participants ha:d significantly longer firing duration and higher median frequency within a gait cycle for al.l the muscle groups, these indicated of the EMG characteristics of in the spastic muscles. In addition, the CP produced significantly smaller root mean square value in tibialis anterior muscle than the normal; this indicated that the tibialis anterior muscle of GP was weakness or atrophy. Because of good objectivity and reproducibility, employing RMS and the MF could :be suggested to be the parameters for further gait studies.
