Abstract
Question
Is ultra-short-wave diathermy (USWD) safe and effective in coronavirus disease 2019 (COVID-19) ?
Design
Single-centre, evaluator-blinded, two-arm, parallel design, randomized controlled clinical trial.
Participants
Moderate and severe COVID-19 patients with acute respiratory syndrome.
Intervention
USWD for 10 minutes twice daily for 12 consecutive days along with standard medical treatment (USWD group, n = 25), versus standard medical treatment alone (control group, n = 25).
Outcome measures
The primary outcomes were the duration of recovery and negative conversion rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on days 7, 14, 21, and 28. Secondary outcomes included clinical status (seven-category ordinal and systemic inflammatory response syndrome (SIRS) scores), computed tomography (CT), routine blood tests, and adverse events.
Results
Time to clinical recovery (USWD 36.84±9.93 vs. control 43.56±12.15, P = 0.037) was significantly shortened with a between-group difference of 6.72 days. Clinical status was improved with significant between-group differences on day 28 (SIRS, P = 0.011; seven-category scale, P = 0.003). The rate of RNA negative conversion at days 7 (P = 0.066), 14 (P = 0.239), 21 (P = 0.269), and 28 (P = 0.490) was statistically insignificant. Moreover, insignificant differences were observed in the artificial intelligence-assisted CT analysis. No treatment-associated adverse events or worsening of pulmonary fibrosis were observed.
Conclusion
USWD, as adjunctive therapy, shortened the recovery course and improved clinical status of patients with COVID-19 without aggravating pulmonary fibrosis. the findings are limited due to the small sample size and early termination.

Blinding This was an assessor-blinded controlled study, due to the nature of the interventions, the study could not be therapist or patient blinded; however, a well-trained health care team consisting of two evaluators, two statisticians, and two data collectors were blinded to the groups/treatment allocation. Power Analysis 17 We estimated that with an 80% power, 5% two-sided type I error rate, and an effect size of 0.72, the enrolment of 62 participants would be enough to detect a statistically significant between-group difference of 6.6 days in the length of recovery from symptom. Sex as a biological variable The exclusion criteria were (1) Positive tests for other pathogens such as Tuberculosis, Mycoplasma, (2) People with metal implants or pacemakers, (3) Patients with respiratory failure or requiring mechanical ventilation, (4) Patients with multiple organ failure who need ICU monitoring and treatment, (5) Those having a bleeding tendency or active bleeding in the lungs, (6) Those with shock, (7) Cancer patients and those with severe underlying diseases, (8) Patients with severe cognitive impairment,(9) Pregnant or lactating women, (10) Those without signed informed consent, (11) Those with other contraindications to short wave diathermy.
