Effects of Exercise and Acupuncture on Chronic Insomnia: a Randomized Control Trial

Change from baseline anxiety to 12 weeks

时间窗: baseline, week 12

Prior sleep state anxiety will be assessed with the State-Trait Anxiety Inventory-STAI,25 the Portuguese version of which was validated by Gorenstein and Andrade.26 This scale encompasses 20 items and provides a one-dimensional measurement of anxiety. The volunteers were instructed to answer it 30 minutes before going to sleep at baseline and at the post-exercise evaluation.

Change from baseline quality of life to 12 weeks

时间窗: baseline, week 12

The SF-36 is a multidimensional questionnaire that covers eight components: physical functioning, role limitations due to physical health problems, role limitations due to emotional health problems, social functioning, vitality, general health perception, body pain, and mental health. All scores ranged from 0 to 100, with a higher score indicating better quality of life

Change from baseline mood to 12 weeks

时间窗: 12 weeks

The POMS questionnaire is an instrument to evaluate the acute profile of mood. It has 65 items and 6 domains: tension-anxiety, depression, anger-hostility, vigour-activity, fatigue, and confusion- bewilderment. The total mood disturbance score is derived by subtracting the vigour-activity score from the the sum of scores from the other subscales

Change from baseline insomnia to 12 weeks

Insomnia Severity Index (ISI) was administrated at baseline and post treatment to assess insomnia-related complaints. It is a short and easy self-applied scale with 7 items scored from 0 to 4, with a total score varying from 0 to 28. The total score is interpreted as follows: absence of insomnia (0-7); sub-threshold insomnia (8-14); moderate insomnia (15-21); and severe insomnia

Change from baseline sleep diary to 12 weeks

时间窗: baseline, week 12

The sleep diary was used to evaluate the subjective perceptions of sleep. Participants were instructed to complete the diary every morning after waking for 1 week. The parameters evaluated were sleep onset latency, wake after sleep onset, total time in bed, number of arousals, sleep quality, feeling rested in the morning, and sleep efficiency (calculated retrospectively by the researchers as the ratio of reported total sleep time and reported total time in bed multiplied by 100 \[9\]). These data were averaged for each volunteer for pre- and post-treatment assessment weeks.

Change from baseline polysomnography to 12 weeks

时间窗: baseline, week 12

Polysomnographic recording included an electroencephalogram, an electrooculogram, an electromyogram, and an electrocardiogram. Measurements of air flow (oral and nasal), respiratory effort (thoracic and abdominal), body movement, and oxygen saturation were also taken. The measured variables included total sleep time, sleep efficiency (ratio between total sleep time and total recorded time multiplied by 100), sleep onset latency, wake after sleep onset, arousals, sleep stages (N1, N2 and N3 non-rapid eye movement \[non-REM\] sleep and REM sleep), latencies for each sleep stage. Two researchers who were blinded to the study design performed the staging and analysed the polysomnographic events using international criteria

Change from baseline sleep quality to 12 weeks

时间窗: baseline, 12 weeks

The PSQI assesses sleep quality over a 1-month period. The questionnaire consists of 19 self-rated questions and 5 questions that should be answered by bedmates or roommates. The latter questions are used only for clinical information. The 19 questions are categorized into 7 components, graded on a score that ranges from 0 to 3. The PSQI components are as follows: subjective sleep quality (C1), sleep latency (C2), sleep duration (C3), habitual sleep efficiency (C4), sleep disturbances (C5), use of sleeping medication (C6) and daytime dysfunction (C7). The sum of scores for these 7 components yields one global score, which ranges from 0 to 21, where the highest score indicates worst sleep quality. A global PSQI score greater than 5 indicates major difficulties in at least 2 components or moderate difficulties in more than 3 components.
