Year: 2008
Type: article
Study designs: Randomized Controlled Trial, Clinical Trial
Abstract: STUDY OBJECTIVES: To determine the efficacy of a novel behavioral intervention, Tai Chi Chih, to promote sleep quality in older adults with moderate sleep complaints. DESIGN: Randomized controlled trial with 16 weeks of teaching followed by practice and assessment 9 weeks later. The main outcome measure was sleep quality, as assessed by the Pittsburgh Sleep Quality Index (PSQI). SETTING: General community at 2 sites in the US between 2001 and 2005. PARTICIPANTS: Volunteer sample of 112 healthy older adults, aged 59 to 86 years. INTERVENTION: Random allocation to Tai Chi Chih or health education for 25 weeks. RESULTS: Among adults with moderate sleep complaints, as defined by PSQI global score of 5 or greater, subjects in the Tai Chi Chih condition were more likely to achieve a treatment response, as defined by PSQI less than 5, compared to those in health education (P < 0.05). Subjects in the Tai Chi Chih condition with poor sleep quality also showed significant improvements in PSQI global score (P < 0.001) as well as in the sleep parameters of rated sleep quality (P < 0.05), habitual sleep efficiency (P < 0.05), sleep duration (P < 0.01), and sleep disturbance (P < 0.01). CONCLUSIONS: Tai Chi Chih can be considered a useful nonpharmacologic approach to improve sleep quality in older adults with moderate complaints and, thereby, has the potential to ameliorate sleep complaints possibly before syndromal insomnia develops.
