Effect of varying frequency, intensity, and pulse duration of transcutaneous electrical nerve stimulation on primary hyperalgesia in inflamed rats. ECAP growth function to increasing pulse amplitude or pulse duration demonstrates large inter-animal variability that is reflected in auditory cortex of the guinea pig. Increasing MAT may indicate a higher DECP. This is usually set in microseconds (µs), but sometimes in milliseconds (ms). This 'restrictive' effect of TES on tongue pressure may have the potential to be used during a resistive exercise paradigm for tongue elevation during swallowing. Author … Gopalkrishnan P(1), Sluka KA. Functional Electrical Stimulation ... – Use of FES for a finite time period to minimize impairments and to encourage motor relearning in context of function ... Pulse duration Mean lingual-palatal peak pressures (mmHg) across different TES conditions. Electrical pulses were delivered at 100 Hz (1-ms pulse duration) and 20 Hz (5-ms pulse duration) for the high (HF) and low (LF) frequency protocols, respectively. In experiment 4, pulse rate discrimination was compared for stimuli with differing pulse durations, and in four out of five subjects, there was no effect of pulse duration.
