AI-extracted from the abstract| Characteristics | Randomized controlled trial protocol Double-blind |

| Sample size | 173 |
| Population | Adults with chronic musculoskeletal pain |
| Interventions | Mindful breathing mindful breathing + direct pointing instruction |
| Duration | Four 30-minute sessions; 3-month follow-up |
| Measures | self-report measures of self-transcendence, electroencephalography (EEG; theta activity), functional near-infrared spectroscopy (fNIRS; default mode network activity), acute pain intensity, pain-related functional interference |
| Key findings | The authors propose that adding direct pointing instruction to traditional mindful breathing may enhance self-transcendence and thereby produce pain relief, and they describe this as the first randomized controlled trial to test whether direct pointing produces analgesia by eliciting self-transcendence. No results are reported; the trial is designed to assess self-transcendence, EEG theta activity, default mode network activity, pain intensity, and pain-related functional interference. |
Abstract
Background: Chronic musculoskeletal pain (CMP) imposes a significant psychological, physical, and emotional burden on millions of adults in the United States. A challenge in treating CMP is its tendency to become enmeshed with a person's sense of self. Mindfulness-based interventions (MBIs) offer a promising approach to help patients disentangle pain from their sense of self. However, rigorous research is needed to determine which styles of mindfulness practice most effectively promote self-transcendence, a candidate mechanism for durable pain relief.
Objective: This study aims to evaluate whether adding direct pointing instruction to traditional mindfulness breathing enhances self-transcendence and pain relief. We will assess the effects of two mindfulness training protocols, mindful breathing and mindful breathing + direct pointing instruction, on subjective and neurophysiological markers of self-transcendence, and on pain-related outcomes.
Methods: In this study, we will conduct a three-arm randomized controlled trial with 173 adults with CMP, assigned to one of the following conditions: 1) four, 30-minute sessions of traditional mindful breathing instruction, 2) four, 30-minute sessions of mindful breathing + direct pointing instruction, or 3) a waitlist control condition. Self-transcendence will be assessed during the first and final intervention sessions using validated self-report measures and psychophysiological indices, including electroencephalography (EEG; theta activity) and functional near-infrared spectroscopy (fNIRS; default mode network [DMN] activity). Primary outcomes include changes in self-transcendence, theta activity, and DMN activity. Secondary outcomes include acute pain intensity and pain-related functional interference, measured at baseline and 3-month follow-up.
Results: Data collection began in October of 2024 and conclude by May of 2027. As this is a protocol paper, no results are yet available. We will report recruitment rates, baseline characteristics, and initial outcome trends in the full trial results paper.
Conclusions: This will be the first randomized controlled trial to examine whether direct pointing instruction produces analgesia by eliciting self-transcendence. Findings may advance understanding of the mechanisms underlying mindfulness-based pain relief and inform the development of more targeted, identity-focused MBIs for chronic pain. Results will be disseminated through peer-reviewed publications, conference presentations, and stakeholder engagement, with potential implications for clinical practice.
