Abstract

|
|
The purpose of this study was to determine the effects of high voltage pulsed current(HVPC) and low voltage pulsed current(LVPC) on posttraumatic edema formation in frog hind limbs.
In this study, 16 bullfrogs(Rana Catesbeiana), weighting 182g to 340g, were used. Limb 16 anesthetized bulifrogs were systemically injuried by weight drop. One hind limb of each frogs was randomly selected to receive continous 120 pps HVPC and
100
pps
LVPC at 90% of motor threshold(HVPC : 33.3V, LVPC : 0.2-1mA). The opposite hind was remained as a control. A series of six 30-minute treatent(interrupted by 30-minute rest) was begun minutes after injury.
@ES The results were as follows.
@EN 1. Cathodal HVPC has been shown to be effective in curbing posttraumatic edema formation in frogs, but anodal HVPC did not effect.
2. Volumes of hind limbs treated with LVPC were not significantly different over time from those of untreated lhnd limbs.
3. Therefore, waveform(HVPC versus LVPC) seems to influence the efficacy of electrotherapy for edema control.
4. Electrical stimulation were not increased edema formation on frog hind limbs.
