In this episode, we unpack the Interstitial Inflammatory Stasis (IIS) hypothesis introduced by Tuckey et al. (2021) in Frontiers in Pain Research. The authors propose that after injury or immune activation, inflammation can become “trapped” within the body’s microscopic fluid channels creating a self-perpetuating loop of congestion, fascial tension, and pain. You’ll learn how this model integrates existing pain theories into one fascia-based framework. We’ll also explore how these ideas align with occupational therapy practice: restoring interstitial flow through movement, breath, manual therapy, and autonomic regulation.
