Purpose: The purpose of this study is to examine and evaluate the effects of auricular acupressure on musculoskeletal pain, depression and sleep of the elderly who are institutionalized in long-term care facilities. Methods: The research was conducted in a non-equivalent control group and non-synchronized design with data collected from October to December, 2016. The subjects were from long-term care facilities for the elderly in D city and divided into an experimental group (24 subjects) and a control group (25 subjects). Results: After the intervention, the experimental group showed significant improvement in degree of musculoskeletal pain on time (x²=23.89, p<.001) and degree of depression on time and group (x²=37.42, p<.001, U=122.0, p<001) and degree of sleep on time (x²=33.62, p<.001). Thus, the suggested hypothesis is partially supported. Conclusion: Auricular acupressure therapy is expected to be a practical and efficient nursing intervention for the elderly institutionalized in long-term care facilities.
