BACKGROUND AND PURPOSE: Several years after the acute polio illness, patients may develop new post-polio symptoms. The purpose of the present study was to evaluate patients with post-polio symptoms with regard to perceived fatigue, functional ability, muscle strength, pain and with regard to measured physical fitness and isometric muscle strength. In addition, the relationship between the results of these subjective and objective measurements was investigated. METHOD: This was a prospective cross-sectional study in which 32 patients with post-polio symptoms were included. Main outcome measures were the Fatigue Severity Scale (FSS), the Disability Rating Index (DRI), pain intensity, pain distribution, self-reported and measured muscle strength and oxygen uptake. RESULTS: A marked reduction in isometric muscle strength compared to normal data, high scores in fatigue, widespread pain, low oxygen uptake and difficulties in performing some daily activities were found. Self-reported general muscle strength, pain intensity and pain distribution correlated significantly with patients' perceived fatigue and function at the activity level. There was no significant correlation between self-reported and measured results except for that found between isometric muscle strength in the legs and patients' perceived general muscle strength and oxygen uptake. CONCLUSIONS: Evaluation of pain intensity, pain distribution, perceived muscle strength, fatigue and ability to perform daily tasks reveals important aspects of health status in patients with post-polio symptoms. Reduction in isometric muscle strength was not reflected in those tests or in reported symptoms, and should be monitored independently using a sensitive assessment tool. Accurate screening of isometric muscle strength in isolated muscle groups contributes to therapeutic management in making a functional diagnosis at the level of body function and structure when designing specific training programmes and in motivating patients. An evaluation combining self-reports with sensitive muscle strength measures provide supplementary information and is appropriate for evaluating these patients in physiotherapy practice.
