[Moxibustion on mental disorder in close contacts of coronavirus disease 2019: a randomized controlled trial]

To observe the effect of moxibustion combined with Daiwenjiu plaster on mental disorder and self rating symptoms in close contacts of coronavirus disease 2019 (COVID-19) during quarantine.

A total of 240 close contacts of COVID-19 were randomized into an observation group (120 cases, 18 cases dropped off) and a control group (120 cases, 58 cases dropped off). Conventional observation was adopted in the control group. Moxibustion combined with Daiwenjiu plaster was given in the observation group, moxibustion was applied at Zusanli (ST 36), Hegu (LI 4) and Shenque (CV 8), 10 min each acupoint, once a day; Daiwenjiu plaster was applied at Dazhui (GV 14) and Feishu (BL 13) for 3 to 6 h each time, once every 2 days, the treatment was required for 2 weeks. Before and after treatment and in the follow-up of 2 weeks after treatment, self-reporting questionnaire 20 (SRQ-20), self-rating anxiety scale (SAS) scores and self rating symptoms were evaluated in the two groups.

In the follow-up, SRQ-20 score was decreased compared before treatment (P<0.01), SAS score was decreased compared before and after treatment (P<0.01, P<0.05) in the observation group. After treatment and in the follow-up, SRQ-20 scores in the observation group were lower than those in the control group (P<0.05, P<0.01). After treatment, the case proportion of fatigue in the observation group was higher than that in the control group (P<0.05). In the follow-up, the case proportion of tension was lower than that in the control group (P<0.05).

Moxibustion combined with Daiwenjiu plaster can effectively improve the mental disorder in close contacts of COVID-19.
