Abstract
AIM
The study compared responders and nonresponders to transcranial direct current stimulation (tDCS) regarding clinical pain outcomes in knee osteoarthritis (OA) patients.
PATIENTS AND METHODS/MATERIALS
Sixty participants received home-based active tDCS, and clinical pain outcomes were compared between responders and nonresponders.
RESULTS
Latent class growth analyses classified 41 participants as responders and 19 as nonresponders. Responders showed significantly greater decreases in pain intensity from baseline to post intervention than nonresponders (p < .001). Participants with higher BMI (p = .02) and weight (p = .005) were more likely to respond, while no significant sociodemographic differences were found.
CONCLUSIONS
Identifying characteristics of nonresponsive tDCS subgroups can tailor treatments for each group.
