Effectiveness of transcutaneous electrical acupoint stimulation for improving depressive mood status among nursing home elders in Taiwan: a pilot study.

The purpose of this study was to test the effectiveness of transcutaneous electrical acupoint stimulation (TEAS) to improve depressive mood status among elders in a nursing home in Taiwan. This was an experimental, pre- and posttest study with 2 groups. Nine subjects in the experimental group received TEAS for 15 minutes, 5 times a week for 1 month. Seven subjects in the control group received social visits for 15 minutes, 5 times a week for 1 month. Results indicated that the posttest depression scores significantly differed between the 2 groups. Subjects in the experimental group showed a statistically significant improvement in depressive mood status, but changes in the depressive mood status of subjects in the comparison group were not statistically significant. In conclusion, TEAS can be a safe, easy, and noninvasive technique for nursing home staff to improve the depressive mood status of elders.
