Background: The purpose of this study was influence of change of electrical stimulation time on body regions affects on electrical current threshold. Methods: The present study is to examine the effect of silver spike point (SSP) electrical stimulation (1Hz), transcutaneous electrical nerve stimulation (TENS, 100Hz), and interferential current therapy (ICT, 50Hz) from the low back and scapulodorsal and knee joint regions on stimulation-induced current thresholds from the elderly (over sixty) people (male:72, female:91) in senior welfare center. Result: The low back region, but not scapulodorsal and knee joint region, significantly increased the TENS and ICT, but not SSP, electrical stimulation, significantly increased the time-dependent current thresholds in elderly patients. Conclusion: Therefore, these results, in part, suggest that the TENS and ICT were shown to be a more adaptable method of stimulation, and that needed of the development of senile specialized physical therapy and the utilization of senior leisure facilities such as senior welfare center the others.
