What this trial studies

This study investigates the effectiveness of transcranial direct current stimulation (tDCS) combined with a Cognitive-Behavioral intervention (CBI) in reducing postoperative pain for veterans undergoing total knee or hip arthroplasty. A total of 132 participants will be randomly assigned to one of four groups to receive either real or sham tDCS and either a real or education-only CBI. The study aims to assess pain levels and opioid usage during the hospital stay and at follow-up intervals of 1, 3, and 6 months post-surgery. The goal is to determine if this combined approach can lead to better pain management outcomes without the need for additional medication.

Who should consider this trial

Good fit: Ideal candidates are veterans scheduled for unilateral total knee or hip arthroplasty who can understand and follow instructions.

Not a fit: Patients with implanted medical devices above the waist, pregnant individuals, or those with a history of seizures may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative pain and opioid use for veterans after knee or hip surgeries.

How similar studies have performed: While the combination of tDCS and CBI is a novel approach, previous studies have shown promise in using tDCS for pain management.
