Cyclic sighing in the clinic waiting room may decrease pain: results from a pilot randomized controlled trial

Pain is a common medical experience, and patient access to pain management could be improved with novel intervention formats. Emerging evidence indicates brief, asynchronous, single-session interventions delivered in the clinic waiting room can improve patient outcomes, but only a few treatment modalities have been investigated to date. Breathwork is a promising approach to managing acute clinical pain that could be delivered asynchronously in the clinic waiting room. However, the direct impact of a breathwork intervention (e.g., brief cyclic sighing) on patients' pain and psychological distress (e.g., anxiety and depression symptoms) while waiting in the clinic waiting room remains unexamined. This single-site, pilot, randomized controlled trial examined the impact of a 4-minute, asynchronous, cyclic sighing intervention on participants' acute clinical symptoms in the x-ray waiting room of a walk-in orthopedic clinic relative to a time- and attention-matched injury management control condition. Pain unpleasantness, pain intensity, anxiety symptoms, and depression symptoms were measured in the study. Participants receiving the cyclic sighing intervention reported significantly less pain unpleasantness and pain intensity while waiting for an x-ray relative to controls. Anxiety symptoms and depression symptoms were not found to differ by condition. Results from this RCT indicate a brief, asynchronous, cyclic sighing intervention may be capable of quickly decreasing pain in the waiting room. Continued investigation is now needed to determine if embedding brief, asynchronous, cyclic sighing interventions in clinic waiting rooms has the potential to help people experiencing acute pain feel better faster.
