This scoping review systematically maps how graded motor imagery and its individual components have been prescribed in clinical trials for chronic pain using a structured reporting framework. It shows that while full graded motor imagery interventions largely follow the original protocol, trials of individual components display substantial variation in dose, sequencing and delivery, often with incomplete reporting. These findings clarify sources of heterogeneity in the literature and support more consistent intervention reporting and design to strengthen future synthesis and clinical translation.
