Abstract
During the coronavirus disease 2019 epidemic, acupressure has been widely used as a complementary treatment for coronavirus disease 2019 in China, but its safety and effectiveness have not been determined until now. This was a prospectively observational study containing 400 cases of mild infection of Omicron who were admitted to Chongming Flower Expo Makeshift Hospital from April 1, 2022 to May 1, 2022. Patients were assigned to receive basic treatment or a combination with acupressure treatment (5 minutes per acupoint, at least twice daily), from admission to discharge. The conversion time of viral RNA assay, the recovery time of symptoms and the clinical cure rate at day 7 were compared in 2 groups. All cases were included in the final analysis. The time to conversion of viral RNA assay (6 vs 7 days, P < .001) and time to symptom recovery (2 vs 4 days, P < .001) were markedly shortened in the acupressure treatment group compared to controls. The time to recovery from individual symptoms of coughing, a sore throat, a fever, fatigue, poor appetite, and insomnia were shorter in the treatment group compared to the control (all P < .05), but there was no statistical difference in reducing the recovery time from headache, muscle ache, anxiety, loss of taste between 2 groups (all P > .05). In addition, acupressure therapy also revealed a higher clinical cure rate at day 7 than basic treatment alone (91% vs 65%, P < .001) and reported no serious adverse events. This study provided evidence for acupressure therapy in treatment of Omicron infection concerning the viral load disappearance and the clinical symptoms improvements. Findings were expected to help guide efforts to position acupressure therapy as a therapeutic option for patients with Omicron variant.
