Summary

This study tested whether a gentle, noninvasive microcurrent treatment can reduce muscle pain in people who had COVID-19. Forty adults with post-COVID musculoskeletal pain were randomly assigned to receive either real or sham microcurrent therapy for 12 sessions. Researchers measured pain intensity, sleep quality, anxiety, and quality of life to see if the treatment helps.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: microcurrent therapy (noninvasive neuromodulation)
What this could lead to: If it works, this could offer a drug-free way to reduce pain and improve sleep and quality of life for people with lingering post-COVID muscle pain.
What could go wrong: This is a small, early-stage trial with only 40 participants. The sham group may also improve, and results may not apply to everyone with post-COVID pain.
