Post-stroke fatigue is highly prevalent and disabling. However, its causes and consequences in the chronic phase are not fully understood. The aim of this cross-sectional study is to explore functional correlates of post-stroke fatigue in the chronic phase.

RECRUITINGFatigue Severity Scale (FSS)
9-item fatigue scale (Score/7) Minimum value = 1, Maximum value = 7 An average score greater than or equal to four signifies pathological fatigue
Time frame: assessment during 1 day study visit
Pittsburgh Sleep quality index
Sleep assessment. The score of seven components are summed to provide a global score from 0 to 21. A global score greater than five is indicative of poor sleep
Time frame: assessment during 1 day study visit
ACTIVLIM specific to patients with stroke
Rasch-validated activity assessment. Self-report 20-item questionnaire based on the International Classification of Functioning, Disability and Health and includes activities related to self-care, transfer, mobility, manual ability and balance. Participants have to evaluate the perceived difficulty of performing each activity if realised without technical or human assistance. Each item has three response possibilities (impossible, difficult, easy)
Time frame: assessment during 1 day study visit
Hospital Anxiety and Depression Scale (HADS)
Mood assessment. Self-report questionnaire with anxiety and depression subscales, each consisting of 7 questions. Score each item from 0 (no symptoms) to 3 points (maximum impairment) The cutoff for a pathological score is ≥ 7 for each subscale
Time frame: assessment during 1 day study visit
6-minute walk test
Speed decrement (distance first minute - distance last minute). The distance walked each minute and the total distance walked were measured. Performance fatigability was assessed by the difference of distance walked during the first and sixth minutes.

Neuromuscular Fatigability Index
Decrement in isometric strength of knee extensors during fatiguing task The NMFI is calculated by the difference between the putative torque-versus-time curve if the subject had maintained the maximal torque recorded during the first 5 seconds for 45 seconds, considered as a score of 100 arbitrary units, and the actual area under the torque-versus-time curve. A higher NMFI score indicates higher fatigability
