Fatigue is a symptom, defined as "a subjective lack of physical and/or mental energy that is perceived by the individual or caregiver to interfere with usual or desired activities." In contrast, fatigability is an attribute reflecting an individual's capacity to meet an exertional demand. Fatigability enhances the interpretability of functional assessments and adds important information to fatigue symptom reports. This symposium provides an overview of the conceptualization and measurement of fatigability as elaborated in the context of the ICF Framework, presents empirical data that distinguishes approaches to measuring fatigability, and traces the implications for research and rehabilitation practice.
