What this trial studies

This study investigates the efficacy of transcranial direct-current stimulation (tDCS) as a treatment for refractory cancer pain in palliative care patients. Participants will receive 20 minutes of tDCS daily for five consecutive days, with one group receiving active stimulation and another receiving sham stimulation, ensuring blinding for both patients and investigators. The goal is to improve patients' quality of life and daily functioning, allowing them to return home under better conditions. The study aims to provide a new, bedside-appropriate treatment option for patients who often experience severe pain that is inadequately managed by traditional opioid therapies.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and over with confirmed cancer at a palliative stage experiencing daily pain intensity of 4/10 or greater.

Not a fit: Patients with uncontrolled epilepsy, major depression, or those unable to self-assess pain will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve pain management and quality of life for patients with refractory cancer pain.

How similar studies have performed: While tDCS is a relatively novel approach in this context, preliminary studies have shown promise in using tDCS for pain management, suggesting potential for success.
