[Polio paralytic. New problems: postpolio syndrome]

Area of Science:

• Neurology
• Rehabilitation Medicine
• Epidemiology

Background:

• Post-polio syndrome (PPS) is a neurological condition affecting polio survivors.
• Characterized by new muscle weakness, fatigue, and pain decades after the initial infection.
• Affects an estimated 20-85% of individuals with a history of polio.

Purpose of the Study:

• To summarize the historical context and clinical features of post-polio syndrome.
• To outline the diagnostic criteria and potential pathogenetic factors.
• To discuss current management strategies for PPS.

Main Methods:

• Literature review of historical descriptions and modern studies on post-polio syndrome.
• Analysis of diagnostic criteria established in 2000.
• Synthesis of proposed pathogenetic mechanisms and treatment approaches.

Main Results:

• PPS emerges 15+ years post-polio, presenting as new weakness, atrophy, and fatigue.
• Diagnostic criteria were established in 2000 to define PPS.
• Pathogenesis remains unclear, potentially involving aging, persistent inflammation, or genetic factors.

Conclusions:

• Post-polio syndrome significantly impacts functional abilities in polio survivors.
• Current treatment is primarily symptomatic and includes moderate muscle training.
• Further research into pathogenesis is needed to develop effective therapies.
