简要总结
In this a 12-week, single blinded, randomized sham controlled, and cross-over clinical trial. It will be conducted to explore the safety and efficacy of acupuncture for olfactory dysfunction in infected COVID-19 patients in Hong Kong.
详细描述
This is a single blinded, randomized sham controlled, and cross-over clinical trial. 40 Post COVID-19 patients presenting to olfactory dysfunction will be recruited. 40 patients will be randomly assigned into 2 groups, the acupuncture group (AC) and the sham acupuncture group (SAC) with 1:1 ratio, for 4-week treatment and 2-week follow-up. After the follow-up, the sham group will be conducted with real acupuncture for another 4 weeks and the real acupuncture group will be conducted with the 4-week sham acupuncture.

盲法说明
Subjects of both groups will be randomly assigned into 2 groups, the acupuncture group or the control (sham) acupuncture group with 1:1 ratio. For randomization, simple, complete non-sequential random numbers will be generated in advance by a computer program in a block of four, and kept by the principal investigator. After a patient's eligibility is confirmed, a randomization number which corresponds to the group allocation will be provided to the acupuncturist by the PI. This arrangement will ensure that the clinical assessor and participants are blinded to the allocation.

研究组 & 干预措施
acupuncture group
Subject will be scheduled for a total of 8 sessions of acupuncture treatment, to be done by the 30 minutes for each session, twice per week over a 4-week period.
Body acupuncture will choose eight acupoints as Yingxiang (LI20),Shangxing (GV23), BiTong, Yintang, Hegu. Disposable acupuncture needle (0.25 mm in diameter and 25-30mm in length) are inserted at a depth of 10-25 mm obliquely into scalp acupuncture points (ShangXing, YinTang) and straightly into face/body acupuncture points (Yingxiang, BiTong, Hegu).
We will also deliver electro-acupuncture will be applied to the face points at fast and dispersed waves through electric needle stimulator which is provided by Chinese Medicine Clinic (ES-160 6-Channel Programmable electro-acupuncture) for 30 minutes.

sham-acupuncture group
For subjects assigned to control group, Streitberger's non-invasive acupuncture needles (Gauge 8 x 1.2" / 0.30 x 30 mm) will be applied to serve as sham control at the same acupoints with the same stimulation modality, except that the needles are only adhered to the skin instead of insertion. Its validity and credibility have been well demonstrated.

结局指标
主要结局
ASOF scores
时间窗: 1, 6, 8, 12, 14 weeks
The Assessment of Self-reported Olfactory Functioning and olfaction related quality of life (ASOF) is a 12-item validated questionnaire, it can be subdivided into three domains: the one-item subjective olfactory capability scale (SOC), the five-item self-reported capability of perceiving specific odors scale (SRP), and the six-item olfactory-related quality of life (ORQ) scale. We proceeded to calculate cutoff scores for the three scales. Patients will be considered to have abnormal olfactory capabilities if the SOC score was equal to or less than 3. Scale from 10 (best possible) to 0 (worst possible-unable to smell). Patients were considered to have problems smelling odors if the SRP score was equal to or less than 2.9 (Scale from 0 to 5) Patients were considered to have smell-related problems in quality of life if the ORQ score was equal to or less than 3.7 (Scale from 0 to 6)
sQOD-NS scores
时间窗: 1, 6, 8, 12, 14 weeks
The Short version of the Questionnaire of Olfactory Disorders-Negative Statements (sQOD-NS) is a 7-item patient-reported outcome questionnaire. Patients rated the item proposition from 0 (agree) to 3 (disagree) with total score ranging from 0 (significant impact of olfactory dysfunction on quality of life) to 21 (no impact on quality of life). The sQOD-NS is composed of seven questions including social, eating, annoyance, and anxiety and assessed using a 4-point Likert scale (0-3). A higher score means better olfactory specific quality of life.
