On a cellular level, functional restoration refers to the recovery of normal activity and communication within nerve, muscle and immune cells that are involved in pain.
Chronic pain is often linked to maladaptive cellular changes: overactive nociceptors, hyperexcitable spinal cord neurons and glial cells that release pro-inflammatory cytokines. These changes lower pain thresholds and keep the system in a “sensitized” state.
Functional restoration at this microscopic scale means reversing or balancing these maladaptive processes. For example:
Neurons regain stable firing patterns and more normal thresholds for activation.
Glial cells shift from releasing pro-inflammatory to anti-inflammatory mediators.
Muscle cells rebuild metabolic efficiency and strength after disuse.
Immune cells re-establish a balance between tissue repair and inflammation.
Interventions such as exercise and pulsed radiofrequency) can influence these cellular processes. Over time, this cellular “reset” contributes to a decrease of inflammation and restored functions.
