The intrafascial circulation loop unfolds as a sequence from mechanical input to fluid response. It starts with tissue manipulation, the direct physical stimulus. That manipulation activates mechanoreceptors in the tissue, specifically interstitial receptors and Ruffini endings, converting the mechanical input into neural signals. Those signals engage the autonomic nervous system, producing an autonomic response that modulates local tissue function. The final stage is changes in local dynamic fluid, reflecting shifts in interstitial fluid movement and microcirculation within the fascia. A palpable tissue response is not a separate stage of the loop; it’s an observable outcome that can accompany the process but does not constitute a distinct step. Therefore, the sequence including tissue manipulation, mechanoreceptor stimulation, autonomic nervous system stimulation, and changes in local dynamic fluid represents the complete list.
