ARTICLE HIGHLIGHTS
Research background

Patients with systemic autoimmune rheumatic disease (SARDs) with post- coronavirus disease 2019 (COVID-19) syndrome experience aggravated symptoms.

Research motivation

Given this context, it is essential to establish strategies that can reduce chronic pain and fatigue, and improve equality of life.

Research objectives

To assess the efficacy of transcranial direct current stimulation in treatment of fatigue and pain associated with post-COVID-19 syndrome in patients with SARDs.

Research methods

This is a quantitative pilot study that included nine patients with different SARDs. All patients had reverse transcription-polymerase chain reaction test confirmed COVID-19 as well as significant, persistent fatigue and pain that began to worsen after infection. Anodal transcranial direct current stimulation (tDCS) was administered in five daily sessions (2mA, 20 min). Concomitantly, patients were involved in aerobic exercise program.

Research results

The sample was composed of eight women and one man with a mean age of 48.7 ± 9.6 years. After the tDCS protocol, the pain and fatigue significantly improved as shown by a visual analog scale (P < 0.05). The physical function also improved 9.5 ± 2.7 vs. 6.8 ± 0.8 (P = 0.001) for timed-up-go-test and 10.3 ± 3.7 vs 15.1 ± 4.0 (P = 0.037) for sit-to-stand test. No patient experienced adverse events.

Research conclusions

tDCS may be an effective strategy to treat fatigue and pain due to COVID-19 in patients with SARDs and improve the physical function.

Research perspectives

The present study contributes to new treatment options to treat pain and fatigue in patients with SARDs.
