[Randomized Controlled Clinical Trials of Eye-acupuncture Therapy for Patients with Post-stroke Insomnia].

Objective: To observe the therapeutic effect of eye-acupuncture therapy for post-stroke insomnia.

Methods: Sixty patients (45-70 years in age) with post-stroke insomnia were randomized into eye-acupuncture group and routine acupuncture (body acupuncture) group (30 cases in each). Patients of the eye-acupuncture group were treated by acupuncture stimulation of bilateral Shangjiao (Upper-energizer) and Xin (Heart) regions and those of the routine acupuncture group treated by acupuncture stimulation of Baihui (GV 20), Sishencong (EX-HN 1), Anmian (EX-HN 16), etc. After , the filiform needles were retained for 20 min, and the treatment in both groups was conducted once a day, with 15 days being one therapeutic course and 2 courses altogether. The Pittsburgh Sleep Quality Index (PSQI) including the subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, daytime dysfunction, and total PSQI score was used to evaluate the overall sleep quality. The clinical efficacy was assessed according to the "Guiding Principles of Clinical Trials for New Drugs of Traditional Chinese Medicine" formulated by Chinese Ministry of Health.

Results: Following the treatment, of the two 30 cases in the eye-and routine acupuncture groups, 21 and 9 experienced a marked improvement in their symptoms, 8 and 17 were effective, and 1 and 4 invalid, with the effective rate being 96.7% and 86.7%, respectively. The PSQI scores of the subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, daytime dysfunction, and the total PSQI score were all significantly decreased in comparison with pre-treatment in each group (<0.01). The therapeutic effect of the eye-acupuncture was markedly superior to those of routine acupuncture in reducing sleep latency, sleep disturbances and daytime dysfunction (<0.05), but without significant differences between the two groups in the effective rate, sleep quality, sleep duration, sleep efficiency and total PSQI score (>0.05).

Conclusions: Both eye-acupuncture and routine acupunture are effective in the treatment of post-stroke insomnia, and the eye-acupuncture is better than routine acupuncture in reducing sleep latency, improving sleep disturbances and daytime dysfunction.
