Evaluation of the Transitional Pain Service Specialized Iyengar-Informed Yoga Program for Chronic Post-Surgical Pain: A Pilot Randomized Controlled Trial
Bibliographic record
Abstract
The objective of this randomized controlled trial (RCT) was to evaluate the feasibility and efficacy of a specialized Iyengar-informed yoga intervention for individuals who experience chronic post-surgical pain (CPSP). This prospective, multi-wave pilot RCT was pre-registered at clinicaltrials.gov (NCT03460028) and designed in accordance with the 2010 CONSORT statement. Participants (N = 21) with CPSP were out-patients or community members affiliated with a Toronto hospital. Participants were randomized to an 8-week yoga condition (treatment condition (TC); n = 10) or to a wait-list control condition ((CC); n = 11). The TC participated in an eight-week yoga program (program 1). The CC participated in the same yoga program after their waiting period (program 2). Pain, psychological, and mindfulness measures were collected at two time points for both conditions (before and after yoga program 1) and at a third time point for the CC (after yoga program 2). Of the 19 participants who attended a single yoga class, 100% completed their yoga intervention. There were no adverse events. Participants rated their program satisfaction as 9.73 ± 0.47, on a scale of 0-10, in which higher numbers indicate greater satisfaction. Linear mixed effects growth models were conducted to evaluate main effects of condition at post-intervention, controlling for pre-intervention scores. Post-intervention scores on the primary outcome measure of pain catastrophizing did not differ significantly between the conditions. Pain interference scores were lower (<em>F</em><sub>1, 13</sub> = 5.14, <em>p</em> < 0.05) in the TC compared to the CC. The yoga program for patients with CPSP (1) was feasible, safe, and satisfactory; (2) lacked efficacy in improving the primary study outcome of pain catastrophizing, and (3) demonstrated efficacy in improving pain-interference. This trial points to the merit of a specialized yoga program for CPSP, although further research is needed in this area.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
