Mechanically insensitive C-fibers (C-MIAs) are either unresponsive to mechanical stimuli or have a very high mechanical threshold. First, physical changes (joint effusion and tissue edema) alter the resting and movement-induced forces exerted on the joint tissues, and second, inammatory mediators released within the damaged tissue sensitize articular nociceptive afferents by binding to receptors on the nerve endings.
