A randomised, blinded clinical trial from 2021 once again demonstrates the efficacy of microcurrent in treating pain and functional disorders.

 

The study examined its use in post-operative shoulder pain:

 

“The experimental group, which underwent microcurrent stimulation, showed a significant effect on pain, shoulder function and grip strength compared with the control group, which underwent sham microcurrent stimulation (t = -2.17, -2.22 and 2.213; p = 0.039, 0.035 and 0.036). Conclusions: This study confirms that microcurrent stimulation is effective in the treatment of patients who have undergone rotator cuff repair.” (Yi et al., 2021)

 

Twenty-eight patients took part in the study and were divided into two groups to achieve single-blinded conditions. Thus, n = 14 were in the microcurrent group and n = 14 in the control group.
