Aims: To examine characteristics of fatigued and non-fatigued post-polio patients and, to define potential subgroups across the fatigue continuum. Design: Multi-center study. Subjects: 143 post-polio patients were, by using the Multi Fatigue Inventory 20 General fatigue ratings, subdivided on the basis of percentile distribution into a fatigue, reference, and non-fatigue group. Methods: Data on background, quality of life, fatigue and pain were collected. Descriptive statistics and correlations in each group and Analysis of Variance and Chi2 for group comparisons were performed. To evaluate differences in the strength of associations between physical and mental fatigue, on the one hand, and vitality on the other, non-linear regressions were employed. Results: The fatigued group was younger, had shorter polio duration, more pain, higher Body Mass Index, lower quality of life and were more physically and mentally fatigued. More had contracted polio after 1956 and were under 65 years of age. Mental fatigue had a relatively higher explanatory value than physical fatigue for differences in vitality in the fatigued group, reversed patterns were seen in the other groups. Conclusions: It may be clamed that the fatigued PPS patients may be considered as a subgroup.
