• Ongoing denervation compensated by reinnervation
• Failing capacity to maintain large motor units ie failing capacity to compensate denervation by reinnervation
• Uncompensated denervation leads to decrease of muscle strength

Summary
§ Postpolio patients have an increase of cytokines in the CSF indicating an inflammation in the CNS
§ The inflammation is down treatment with intravenous gammaglobulin
§ Clinically, the downmodulated inflammation leads to an increased muscle strength and a better quality of life, mainly for the general health and vitality domains, as well as for pain and fatigue
§ Recent studies suggest that there are specific biomarkers for PPS in CSF and blood
