Subjects in the placebo acupuncture group will receive non-insertive acupuncture using the sham needle supported by the Park device. This needle has a retractable shaft and a blunt tip, they could not penetrate the skin. We gently placed the sham needle and Park device on the skin. The sham needle is then no longer manipulated to minimize any physiological effects. The selected acupoints and needle retention time were the same as for the acupuncture group. Since oblique insertion is required for acupuncture points on the head, the fixed acupuncture body of the Park device could not be used. Therefore, blunt needles are used to stimulate the head points to reduce the amount of stimulation produced by acupuncture. At the end of the treatment, the acupuncturist also used a dry cotton swab to press the acupoints so that patients could feel the withdrawal of 'real' needles.

Respond to the severity of fatigue from different angles through 14 questions.The Fatigue Scale-14 is composed of 14 items, and the 14 items are divided into two categories. One category reflects physical fatigue, including 1 to 8 items; the other reflects mental fatigue, including 9 to 14 in total 6 items. The highest score for physical fatigue is 8, the highest score for mental fatigue is 6, and the highest total score is 14. The higher the score, the more severe the fatigue.

The epworth sleepiness scale is applied to assess excessive daytime sleepiness. The clinical significance of this table is: sleepiness can be semi-objectively assessed by the epworth sleepiness scale. Any sleep disorder caused by sleep deprivation may lead to change of this scale. This scale has 24 points. A score greater than 6 indicates drowsiness, a score greater than 11 indicates excessive sleepiness, and a score greater than 16 indicates dangerous drowsiness.

SAS is called anxiety self-rating scale, which is a standard for anxiety assessment and a psychological scale used to measure the degree of anxiety state and its changes during treatment. The SAS scale has 100 points in total, and the cut-off value is 50 points, of which 50-59 points are mild anxiety, 60-69 points are moderate anxiety, and more than 70 points are severe anxiety.

Polysomnography refers to the continuous and synchronous acquisition, recording and analysis of EEG, electrooculogram, electromyogram, oronasal airflow, respiratory effort, and saturation of oxygen levels, body position and other physiological and pathological parameters during sleep by sleep technicians all night through computer software in the sleep laboratory. This technology for the diagnosis of sleep disorders is the gold standard for the diagnosis and treatment of sleep disorders.

Heart rate variability (HRV) refers to the fluctuations in the interval between successive heartbeats. It is commonly used to evaluate the regulatory role of the autonomic nervous system on cardiac activity. It is an important noninvasive indicator for evaluating autonomic nervous activity, and is also one of the important indicators for evaluating autonomic nervous changes during sleep.
