Post-stroke fatigue: a treatment protocol that is being evaluated

Abstract

This series of articles for rehabilitation in practice aims to cover a knowledge element of the rehabilitation medicine curriculum. Nevertheless they are intended to be of interest to a multidisciplinary audience. The competency addressed in this article is the neuropsychologist. Purpose: Post-stroke fatigue is a common and debilitating complaint, which has only recently received attention in clinical rehabilitation. Until now, no evidence-based treatments have been available for the condition. Therefore, a new treatment was designed to reduce post-stroke fatigue complaints: Cognitive and Graded Activity Training (COGRAT). Rationale: Following the premise that post-stroke fatigue is primarily caused by brain damage, the treatment aims to prevent fatigue and to manage existing fatigue symptoms. The purpose of the added graded activity programme is to reduce fatigue by changing cognitions and enhancing physical fitness. Theory into practice: COGRAT consists of a cognitive treatment and graded activity programme in small groups over 12 weeks. In the cognitive treatment, patients receive education on post-stroke fatigue and register their activities and fatigue to gain insight into their daily agenda and fatigability. Patients are then taught several compensation strategies. Cognitive behavioural therapy is used to diminish anxiety, facilitate behavioural change and manage fatigue symptoms. The graded activity programme consists of walking on a treadmill, strength training and home work assignments. Maximum heart rate and strength are increased from 40% at the beginning of the training to a maximum of 70%. Considerations for future improvements: COGRAT is currently being evaluated in outpatients with severe post-stroke fatigue in a multicentre randomized controlled trial. Preliminary data suggest both positive short- and long-term effects. Adaptations for other neurological patient groups suffering from fatigue are suggested.
