Approach to Fatigue and Energy Conservation.

Fatigue, a common complaint in individuals with postpolio syndrome (PPS), is defined as an overwhelming sustained feeling of exhaustion and diminished capacity for physical and mental work. A comprehensive medical work-up is needed to rule out all other causes of fatigue. A sleep study should be considered for individuals with PPS who complain of fatigue. Self-reported outcome measures, such as the Fatigue Severity Scale, are reliable and valid tools to measure fatigue in this population. Fatigue management consists of individualized treatment of underlying medical conditions, energy conservation, pacing techniques, and lifestyle modifications.
