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.
Clinical Trial Registration:
www.clinicaltrials.gov identifier is NCT04016272.
