简要总结
Mental fatigue is a major problem for stroke survivors and sometimes remains present years after the event. It is often rated as the most persisting and frustrating symptom. For many, mental fatigue has a significant negative effect on rehabilitation, and patients report difficulties with returning to previous levels of participation in their meaningful everyday activities whether at home, work or in the community.
The development of effective evidence based interventions have been limited by our understanding of post stroke fatigue. This may be attributed to the fact that the underlying mechanisms for post stroke mental fatigue are unknown. Evolving theories suggest that mental fatigue may be associated with a dysfunction in the cognitive domain of attention.
An impairment in the domain of attention may result in previously effortless activities of daily living that require sustained attention to become exhausting. Specific knowledge on the influence of background noise and other distractions on a person's ability to sustain attention after stroke is lacking. This research project will contribute to new and important knowledge in this area.
A total of 30 adults will be reviewed at least 2 months after stroke on tasks that require sustained attention. The investigators plan to observe the influence background distraction has on the ability to do these tasks and whether wearing earphones will assist with concentration levels, and reduce fatiguing situations.
This project provides a unique opportunity to investigate how a dysfunction in the cognitive domain of attention may be related to the experience of mental fatigue after stroke. The investigators will use a reaction time based test, fatigue questionnaires, alongside the wearing of earphones when examining associations. This knowledge may help to determine who is at risk of developing symptoms of mental fatigue. Furthermore, it may shed a light on possible prevention strategies, and provide more suitable guidance to those affected by mental fatigue.
详细描述
Fatigue is reported by stroke survivors as a highly problematic and persisting experience with many rating it as their most severe amongst all post - stroke sequelae. Given the negative impact of fatigue on participation, an investigation into the possible underlying mechanisms mediating fatigue after stroke has clinical implications.
Recent studies indicate that an impairment in the domain of attention is related to the experience of higher fatigue levels. However, the complexity of this mechanism, presentation and measurement have made the findings unclear. In studies, testing methods to identify a dysfunction in the domain of attention can be mentally fatiguing. Moreover, it is not clear whether the impact of contextual factors on concentration levels, such as background noise and distraction, has been considered.
Primary Objective:
Among people with stroke engaging in a task requiring sustained attention, to what extent does the use of noise-cancelling earphones impact on mental fatigue? Fatigue will be assessed using two measures: 1) The Continuous Performance Test, a reaction time based assessment completed on a computer tablet and 2) A Visual Analog Scale for Fatigue, which is paper based.
Design: A cross - over repeated exposure randomised design will be used. Study participants will be randomised to do tasks of sustained attention, followed by a reaction time based assessment on a tablet, first with and then without earphones or first without and then with earphones. The two assessment sessions will be done one week apart to allow for a washout period. Participants will be invited to rank their fatigue levels on a visual analog scale, pre - post these assessments.

主要结局
The Continuous Performance Task
时间窗: 12 minutes
The Continuous Performance Task (CPT) is a computerised reaction time test and is one of the most frequently used, objective tools to measure sustained attention over time. This assessment takes 12 minutes. Sustained attention will be assessed based on changes on performance over time. The task will be completed twice (once with, once without earphones) over the two assessment days.
Change in baseline fatigue at 2 hours - Visual Analog Scale for fatigue
时间窗: 4 x across 2 testing days (1 week apart). Day 1: Before (baseline) and after reaction time assessment (2hours). Day 2: Before (baseline) and after reaction time assessment (2hours)
A VAS consisting of a 10cm vertical line from 1 (no fatigue) to 10 (worst possible fatigue) will be used to obtain the momentary fatigue associated with completing the task of sustained attention. Participants will rank their mental fatigue at the beginning and the end of each reaction time task (on the CPT) performed.
