Changes in Sleep With Auricular Point Acupressure for Chronic Low Back Pain

Area of Science:

• Integrative and Complementary Medicine
• Pain Management
• Sleep Science

Background:

• Chronic low back pain (CLBP) significantly impacts patient well-being, often leading to poor sleep quality.
• Sleep disturbances are prevalent in individuals with CLBP, exacerbating pain and functional limitations.

Purpose of the Study:

• To evaluate the effect of auricular point acupressure (APA) on sleep quality in patients with CLBP.
• To determine the relationship between pain intensity and sleep quality following APA intervention.
• To compare sleep outcomes between APA and sham-APA groups.

Main Methods:

• A randomized controlled trial involving 61 participants with CLBP.
• Participants were assigned to either the auricular point acupressure (APA) group (n=30) or a sham-APA group (n=31).
• Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) at baseline, end of intervention (EOI), and 1-month follow-up.

Main Results:

• At baseline, 87% of participants reported poor sleep quality.
• The APA group demonstrated significant improvements in global PSQI scores and reduced daytime disturbances compared to the sham-APA group at EOI and follow-up.
• In the APA group, sleep duration and wake after sleep onset showed gradual daily decreases during the 4-week intervention.

Conclusions:

• Four weeks of auricular point acupressure is effective in improving sleep quality for individuals with chronic low back pain.
• APA offers a potential non-pharmacological approach to manage sleep disturbances associated with chronic pain conditions.
• Further research is warranted to explore the mechanisms underlying APA's effects on sleep and pain.
