Abstract:Existing research about patients with chronic fatigue syndrome (CFS) suggests that physical activity plays an important role in the progress and maintenance of the disease. The aim of the present study was to further investigate the influence of objective physical activity on CFS patients. To gain better insights into the factors influencing physical activity patients have been examined according to the accuracy of their estimates about their physical activity and their fatigue level. During the experiment 23 participants were provided with an ambulant feedback system. This feedback was either based on the average behavior of healthy people or on one’s own average physical activity. The patient’s objective activity level was measured by a tri-axial piezoelectric accelerometer. Their subjective activity and fatigue level were measured by self-reported scores. In the course of the experiment an increased positive correlation between objective- and subjective activity level was found. During the first week, the baseline level (without feedback) was measured, which revealed significantly a moderate negative correlation between objective activity level and fatigue. No significant differences have been found between the two feedback comparison groups. Consequently, CFS patients do accurately estimate their physical activity. The two feedback groups had no different influence on the patients regarding subjective and objective activity and fatigue. Overall, participants felt more tired as their physical activity level increased
