What this trial studies

This study investigates the effects of open-label placebo (OLP) on acute pain using an experimental model that simulates wound pain through electrical stimulation. Participants will undergo a randomized crossover design where they will receive OLP injections and their pain responses will be measured. The study aims to evaluate the duration and efficacy of OLP analgesia, comparing different administration methods. The research seeks to explore the potential of OLP as a non-deceptive treatment option for managing acute pain.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 to 65 with a BMI between 18 and 25 who can understand the study and provide informed consent.

Not a fit: Patients with chronic pain, neuropathy, or those taking medications that interfere with pain sensation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a novel, non-pharmacological method for managing acute pain without the side effects associated with traditional analgesics.

How similar studies have performed: While the use of open-label placebos is a relatively novel approach, previous studies have shown promising results in various conditions, indicating potential for success in this area.
