SUMMARY:

Introduction: Subacromial pain (SAP) is one of the most common shoulder-
related diagnoses, characterized by persistent symptoms that reduce
functionality and quality of life. Transcranial direct current stimulation (tDCS)
has been extensively studied and presented as a promising clinical tool for
modulating pain perception. Objective: To analyze the effects of tDCS on
pain intensity, upper limb function, quality of life, muscle strength, and
shoulder range of motion in individuals with subacromial pain. Methodology:
A randomized, double-blind, controlled clinical trial. Thirty-three individuals
aged 20 to 69 years, of both sexes, with a medical diagnosis of subacromial
pain were randomly assigned to two distinct groups: active tDCS (n=17) and
sham tDCS (n=16). Both groups underwent 20 minutes of stimulation for five
consecutive days. The same procedures were applied to the sham group;
however, the current was interrupted after 30 seconds. The primary outcome
was pain intensity, assessed using the numerical pain rating scale. Secondary
outcomes included range of motion (ROM), muscle strength, upper limb
function (DASH), and quality of life (SF-36). Assessments were repeated at
the end of the intervention and at a one-week follow-up, during which
participants received a shoulder pain management guide. Results: Both
groups showed similar improvements in pain intensity, DASH scores, and
ROM compared to baseline (p<0.05). Muscle strength significantly increased
over time (p<0.05), but only in flexion (active tDCS) and medial rotation (sham
tDCS). Regarding SF-36 domains, significant improvements (p<0.05) were
observed in functional capacity, pain, vitality, limitations (sham tDCS), and
physical aspects (active tDCS). No significant differences were found
between the groups in any of the analyzed variables (p>0.05). Conclusion:
The effects of tDCS were not superior to those of the sham group in any of
the analyzed variables in individuals with SAP. Therefore, the observed
improvements may be attributed to a placebo effect.
