Background: Sleep disturbance in older people is an important health issue that is associated with many other health problems. Effective interventions are required to address sleep problems in this group. Acupressure has been suggested as a potential therapeutic technique to improve sleep. The aim of this study is to evaluate the effects of an acupressure intervention on sleep quality, anxiety, depression, and quality of life among older persons in residential aged care facilities within an Australian context. Methods/design: This is a randomised controlled trial with two parallel groups in a pre-and post-test study. Study participants will be older people living in residential aged care facilities. They will be assigned to intervention and control groups using computer-generated random numbers. The intervention group will receive 12-min acupressure three times per week for four consecutive weeks, applied on three acupoints: HT7, PC6, and SP6. The control group will receive only routine care. The primary outcome measure is sleep quality, and secondary outcomes include anxiety, depression, and quality of life. Data will be collected before the intervention, immediately after the end of the intervention, and 2 weeks after the intervention. Discussion: This study targets a poorly met healthcare need of older people who are experiencing sleep disturbance and its negative consequences. To the researchers' knowledge, this is the first study evaluating acupressure in an Australian aged care context, using specific acupoints and a standardised acupressure protocol. If the results show positive outcomes, acupressure could be used to manage sleep disturbances for older people in the Australian context as well as in the global ageing population. This will contribute to reducing negative consequences of sleep disturbance and use of sleep medications.
