Acupressure and quality of sleep in patients with end-stage renal disease--a randomized controlled trial

[[abstract]]The purpose of the study is to test the effectiveness of acupressure on sleep quality of end-stage renal disease patients. The study was a randomized controlled trial; qualified patients in the dialysis centers of four major hospitals were randomly assigned into an acupressure group, a sham acupressure group, and a control group. A total of 98 participants were included in the study. The main outcomes measured were the Pittsburgh sleep quality index (PSQI) and the sleep log. Data were collected at pretreatment and following treatment. Primary statistical analysis was by means of Analysis of Covariance, the Kruskal-Wallis Test and repeated measure ANOVA. The results indicated that PSQI scores of the acupressure group have a significantly greater improvement (p0.05). Subscales of PSQI were further analyzed. Results demonstrated significant differences between the acupressure group and the control group in subjective sleep quality (p=0.009), sleep duration (p=0.004), habitual sleep efficiency (p=0.001), and sleep sufficiency (p=0.004). Significant differences in the subscale of subjective sleep quality (p=0.003) between the sham acupressure group and the control group were also observed. Sleep log data showed that the acupressure group significantly decreased awake time and improved quality of sleep over time more than the control group (p
