Brief Summary

Objectives: To evaluate the clinical effects of Zero-Time Exercise (ZTEx) for treating insomnia disorder delivered by a training course. Hypothesis: Subjects in the ZTEx training group will have greater improvement in insomnia symptoms and daytime impairment than those in the sleep hygiene education (SHE) group at week 8. Design and subjects: A randomized controlled trial. 32 inactive subjects with insomnia disorder recruited from the community will be randomized to ZTEx training or SHE groups in a 1: 1 ratio. Study instrument: Insomnia Severity Index (ISI) will be used to assess insomnia symptoms and daytime impairment. Interventions: Subjects in the ZTEx training group will attend two training lessons (2-hour each) to learn ZTEx and practice it every night for 8 weeks; subjects in the SHE group will receive sleep hygiene education with the schedule and duration that are same to the ZTEx training group. Main outcome measures: The primary outcome measure is the ISI score. Other measures include sleep parameters by subjective sleep diary and objective actigraphy, Hospital Anxiety and Depression Scale, Multidimensional Fatigue Inventory-20 and Short Form-6 Dimension. Acceptability and compliance of ZTEx will be evaluated. Data Analysis: Differences in the questionnaire scores, subjective and objective sleep parameters will be examined using a mixed-effects model.

Study Arms (2)

Zero Time Exercise training

EXPERIMENTAL

Subjects in this group will attend two 2-hour ZTEx training lessons. Each subject will receive a handout and an exercise log. The handout includes a picture-illustrating ZTEx step-by-step protocol. The exercise log is for them to record their time spending on performing the ZTEx every day during the 8-week study period.

Other: Zero Time Exercise

sleep hygiene education

ACTIVE COMPARATOR

Subjects in this group will receive two 2-hour lessons of sleep hygiene education delivered by a registered nurse.

Other: Sleep hygiene education

Interventions

Zero Time Exercise encourage people to increase physical exercise by simple movements that can be done any time at any places. We offer a 2-session training course to train the subjects to do zero-time exercise.
