Brief Summary
This study will explore whether sleep disruption in the sub-acute phase of stroke explains variation in clinical motor outcomes, and whether this relationship is mediated by variation in behavioural measures of overnight consolidation.

Outcome Measures
Primary Outcomes (4)
Sleep fragmentation at 1-month
Assessed using actigraphy (wearable activity monitor) over 7-nights (more fragmentation indicates worse sleep).
1 month post-stroke
Symptoms of insomnia at 1-month
Assessed using the Sleep Condition Indicator, a questionnaire assessing self-reported insomnia symptoms (range 0-32, higher scores indicate fewer symptoms of insomnia)
1 month post-stroke
Upper limb ability
Assessed using the Action Research Arm Test (range 0-57, higher score indicates better upper limb ability)
6 month post-stroke
Behavioural motor consolidation
Assessed as change in motor performance on a sequential button pressing task (movement time, in seconds) from training to retest
1 month post-stroke
Secondary Outcomes (6)
Whole body motor impairment
6 months post-stroke
Hand dexterity
6 months post-stroke
Mobility
6 months post-stroke
Estimated Total Sleep Time
1 and 6 months post-stroke
Wake After Sleep Onset
1 and 6 months post-stroke
- +1 more secondary outcomes
Other Outcomes (7)
Electroencephalography (EEG) Sleep Measures
1 month post-stroke
Mood (Depression)
1 and 6 months post-stroke
Risk of Obstructive Sleep Apnoea
1 month post-stroke
- +4 more other outcomes
Eligibility Criteria

- Aged 18 years or above
- Within 1 month of onset of stroke affecting the upper limb as confirmed by clinical diagnosis
You may not qualify if:
- Other neurological condition affecting movement (such as Parkinson's disease, Multiple Sclerosis)
