Patients with post-polio sequelae experience significant fatigue that peaks in the late morning or early afternoon, suggesting a role for energy conservation and frequent rest periods.

May inform timed rest strategies in post-polio fatigue; Level 4 data leaves open prospective validation before practice change.
Fatigue was studied in 12 subjects with post-polio sequelae (PPS). Results of the Fatigue Severity Scale (FSS) demonstrated a mean score of 4.8 +/- 1.6 (non-disabled scores = 2.3 +/- 0.7). The Human Activity Profile (HAP) was not sensitive enough to measure fatigue. Fifty percent of subjects scored below the first percentile based on age and sex matched norms. The Activity Record (ACTRE) results revealed that subjects spent 5% of their time resting and 1% in planning or preparation activities. Fatigue peaked in the late morning or early afternoon and was relieved by rest periods. Use of energy conservation and work simplification skills along with frequent rest periods was suggested as a possible method for managing PPS fatigue.
