Effects of Acupressure on Sleep Quality and Psychological Distress in Nursing Home Residents: A Randomized Controlled Trial.

OBJECTIVE

To compare the efficacy of acupressure with sham acupressure in older-adult nursing home residents presenting with poor sleep quality and psychological distress.

DESIGN

Prospective, randomized, double-blind, sham-controlled trial.

SETTING AND PARTICIPANTS

Sixty-two nursing home residents with poor sleep quality and psychological distress participated in this study. Participants were randomly assigned to an experimental group (n = 31) receiving acupressure at true acupoints (Baihui, Juque, Neiguan, Tianzhu, and Yongchung) or control group (n = 31) receiving acupressure at sham points. All participants received 20 minutes of acupressure before sleeping 3 times a week for 8 weeks. All participants were blinded to group allocation.

MEASURES

Sleep quality and psychological distress were measured using the Pittsburgh Sleep Quality Index and the Kessler Psychological Distress scale, respectively. Both groups' outcomes were assessed by assessors blinded to group allocation at the baseline, the end of the intervention, and 1 month after the intervention.

RESULTS

The experimental group demonstrated significantly more improvement in sleep quality than did the control group at the end of the intervention (10.5 vs 13.3) and 1 month after the intervention (8.3 vs 14.2; both P ≤ .001). Moreover, the experimental group had lower psychological distress levels than did the control group at 1 month after the intervention (14.6 vs 17.9, P = .05). Furthermore, significant differences in mean sleep quality (F = 60.8, P < .001) and psychological distress (F = 24.6, P < .001) were observed in the experimental group between the measurements at baseline and after the intervention.

CONCLUSIONS

Acupressure at true acupoints improves sleep quality, reduces psychological distress, and provides more clinically beneficial effects compared with that at sham points. Future studies should examine whether these effects are maintained in the long term.
