title: [The measurement of EMG and deglutition pressure after glossal reconstruction]
abstract: Newly designed computer system (SAMP-EMG) was utilized,to measure the myoelectric signal in each region of the 100ms integral values and do the power spectral analysis in 10 normal people and 20 patients.At the same time,the pressure of deglutition was determined with the liquid pressure conducting electronic device.The results were :1.In normal EMG,the myoelectric power in anterior tongue is the highest,that in the margin of the tongue is the second,that in dorsum central area is the lowerest;2.There in no effective myoelectric signal detected in any kind flap;3.Normal swallowing pressure is 21.1+/-5.7kPa,the average value of FA is 10.3kPa,PM is 10.8,GC is 14.6.
