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.

Description:

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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	ASOF scores	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)	1, 6, 8, 12, 14 weeks
Primary	sQOD-NS scores	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.	1, 6, 8, 12, 14 weeks
Secondary	UPSIT-TC	The University of Pennsylvania Smell Identification Test (UPSIT) is widely used internationally and the worldwide standard for olfactory testing. UPSIT is a 40-item "scratch and sniff" multiple choice test to assess how well participants can identify different odors. Patients will be required to identify each of the 40 odors from four alternatives listed for each odor. The number of correct responses provided a test score such that patients could be categorized into one of four categories: mild, moderate, severe, or total loss. The test is scored by the number of odors identified correctly to generate a maximum score of 40.	0, 14 weeks
