Brief Summary

In this study, a 16-week randomized, sham-controlled, double-blinded clinical trial will be conducted to to investigate the efficacy and safety of electro-acupuncture compared to sham acupuncture for treatment of long covid neuropsychiatric symptoms.

Detailed Description

This is a prospective, randomized, sham-controlled, double-blinded and multiple center trial on electro-acupuncture for treating neuropsychiatric symptoms in long covid patients. A total of 150 participants will be randomly assigned to the electro-acupuncture and the sham-control group with 1:1 ratio. Both groups will receive 32 sessions of interventions during 16-week treatment duration (2 session per week), and will be followed up for 8 weeks.

Electro-acupuncture groupAcupunctureThe electro-acupuncture intervention will be conducted for 2 session per week during 16-week treatment duration, and will be followed up for 8 weeks. In this study, 7 acupoints are chosen:GV20(Baihui), EX-HN1(Sishencong), EX-HN3(Yintang), SP6(Sanyinjiao), ST36(Zusanli), ST40(Fenglong), and LR3(Taichong). The puncture is made in accordance with the standards of traditional Chinese medicine, to a depth of 1 to 3 cm depending on the thickness of the local tissues. The acupoints are subjected to 2-5 Hz electroacupuncture from an electroacupuncture device at an intensity (5 to 10 mA) that can produce a muscle twitch acceptable to the participant.
Sham-acupuncture groupSham-acupunctureFor subjects assigned to the sham control group, Streitberger's non-invasive acupuncture needles (Gauge 8 x 1.2/ 0.30 x 30mm) will be applied to serve as a sham control at the corresponding non-acupoints, leave 0.5 cun from the corresponding acupoints, with the same stimulation modality. Addtionally, the stimulation will be a "pseudo stimulation", which will be given by connecting the needle to the incorrect output socket of the electrical acupuncture stimulation instrument. The credibility and validity of this system have been well demonstrated. .
Primary Outcome Measures
NameTimeMethod
Cognitive score on the Chinese version of the Mini-Mental State Examination (MMSE) scaleAt baseline (before intervention), at 4, 8, 12, 16 weeks (the end of intervention) and 2 months after intervention (the end of follow-up).

The MMSE can evaluate of five different domains of cognitive functions: (1) Orientation, with a maximum of 10 points, (2) Memory, with a maximum of 6 points, (3) Attention and calculation, with a maximum of 5 points, (4) Language, with a maximum of 8 points, and (5) Design copying, with a maximum of 1 point. It has a maximum score of 30, with MMSE score denotes severity of cognitive impairment as follows; mild: MMSE 21 to 24, moderate: MMSE 10 to 20, severe: MMSE less than 10.

Depression on the Chinese Beck Depression Inventory (CBDI)At baseline (before intervention), at 4, 8, 12, 16 weeks (the end of intervention) and 2 months after intervention (the end of follow-up).

The scale has a total of 21 questions, with an overall score of 63, 14-19 being mild depression, 20-28 being moderate depression, and above 29 being severe depression.

Secondary Outcome Measures
NameTimeMethod
Score of the Short Form 12 (SF12)At baseline (before intervention), at 4, 8, 12, 16 weeks (the end of intervention) and 2 months after intervention (the end of follow-up).

The SF-12V2 is a widely used generic HRQoL instrument, and its Chinese version has been validated and normed in the general Chinese population in Hong Kong. It consists of 12 questions measuring eight domains of health, including physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional and mental health. The scores are generated using an algorithm to generate a combined physical and mental health score for comparison with normative data. In the normative data: 1) the mean score was set to 50; 2) a score \> 50 indicated better physical or mental health than the mean; 3) a score \< 50 indicated worse physical or mental health than the mean.

Score of Insomnia Severity Index (ISI)At baseline (before intervention), at 4, 8, 12, 16 weeks (the end of intervention) and 2 months after intervention (the end of follow-up).

The Insomnia Severity Index in Chinese includes 5 questions to assess the severity and impact of insomnia, on an 0 to 4 scale, with the higher score reflecting worse insomnia symptoms.

Score of Brief Fatigue Inventory-Taiwanese (BFI-T) FormAt baseline (before intervention), at 4, 8, 12, 16 weeks (the end of intervention) and 2 months after intervention (the end of follow-up).

BFI-T form is to assess the severity of fatigue and the impact of fatigue on daily functioning. Scoring Respondents rate each item on a 0-10 numeric scale, with 0 meaning "no fatigue" and 10 meaning "fatigue as bad as you can imagine." Scores are categorized as Mild (1-3), Moderate (4-6), and Severe (7-10).
