The Effect of Acupressure on Sleep Quality of Older People in Australian Residential Aged Care Facilities: A Pilot Randomized Controlled Trial. This study investigated the effects of acupressure on sleep quality, anxiety, depression, and quality of life among older people in Australia. Acupressure improved overall subjective sleep quality and anxiety but no differences in depression and quality of life. Future studies with larger sample sizes are required to generate good evidence.
