Plain English Summary
Background and study aims
A stroke is a serious condition where the blood supply to a part of the brain is cut off, usually by a blood clot blocking blood flow (ischemia) or a bleed in the brain (intracerebral haemorrhage). The majority of strokes are ischemic strokes, in which the arteries that supply the brain with oxygen (carotid arteries) become narrowed or blocked. Intracerebral haemorrhages (ICH) are much less common than ischemic strokes, and occur when a diseased blood vessel in the brain bursts, causing bleeding which causes a sudden increase of pressure on the brain. One of the most common complications of a stroke is weakness on one side of the body (hemiparesis). This can involve weakness in the arms and/or legs, as well as loss of control over the torso (trunk deficit). Previous studies have shown that in individuals with poor trunk control, such as the ability to sit unsupported (poor sitting balance), are less likely to regain their mobility at six months. Despite this, physiotherapy that specifically targets trunk performance is often neglected during early rehabilitation. It is well recognized that more extensive physical rehabilitation following stroke significantly improves a person’s chance of regaining their mobility. Given that trunk function is a good predictor of future mobility, including specific trunk training in early physiotherapy could play an important role. The aim of this study is to look at the effects of providing additional trunk training during early rehabilitation after stroke in order to find out whether a large-scale study would be possible.
Who can participate?
Adults who have suffered a stroke three to seven days previously who are experiencing hemiparesis in the arm and leg and are unable to sit unsupported for 30 seconds (severe trunk deficit). Adults who have suffered a stroke three to seven days previously who are experiencing hemiparesis in the arm and leg and are unable to sit unsupported for 30 seconds and are unable to make their own decisions (lacking mental capacity).
What does the study involve?
All participants undergo 16 additional hours of trunk training over a period of six to eight weeks as well as standard physiotherapy. This involves functional exercises, such as moving in bed, sitting up and standing, as well as exercises designed to strengthen muscles. At the start of the study, and then again after the trunk training programme and six months later, participants complete a number of questionnaires and movement tests in order to find out whether their condition has improved. The amount of participants who could be recruited to take part is also recorded to find out if it is feasible to conduct a larger study. In a sub-study, ten participants who lack the mental capacity (ability to make decisions) to decide if they want to take part who meet the other inclusion criteria also complete the same training program and follow up assessments, to see if there is any difference.
What are the possible benefits and risks of participating?
Participants benefit from receiving additional therapy sessions which could help to improve their recovery. There are no notable risks of participating, although the extra exercise sessions could make participants feel tired.

Condition
Topic: Stroke; Subtopic: Rehabilitation; Disease: Therapy type
Intervention
The patient will receive a minimum of 16 hours of additional trunk training over a 6-8 week period, focussing on strengthening and functional exercises. Specific trunk strength training exercises will be prescribed following an initial assessment of muscle strength. The functional training element will consist of practising functional movements such as bed mobility, lying to sitting, independent sitting, standing and transitions. Sessions will take place daily (as far as possible) and will last for approximately 30 minutes. The training will be in addition to the patient’s usual physiotherapy and take place on the stroke ward, in the hospital gym or in the patient’s place of residence if discharged from acute care before the training is completed.
Participants will be followed up post intervention and at six months.
Sub-study:
Ten participants meeting the main study inclusion/exclusion criteria as detailed above, but who do not have mental capacity to give informed consent will be recruited to participate in this sub-study. Participants will be assessed for capacity by the research nurse as detailed below to comply with the Mental Capacity Act, 2005. If a participant does not have capacity to consent, a personal or nominated consultee will be sought to make a decision on their behalf in their interest.
All other aspects of the study will be identical to the main study.

Primary outcome measure
Feasibility measures of recruitment, retention and attrition will be determined through screening and completion data to measure the number of admitted patients that fulfil the study inclusion/exclusion criteria; consent to take part in the study; complete the trunk training intervention; and complete baseline, post intervention and 6 month follow up assessments of the secondary outcome measures.
Secondary outcome measures
1. Trunk impairment is measured using the Trunk Impairment Scale at baseline, post intervention and at 6 months follow-up
2. Mobility is measured using the Modified Rivermead Mobility Index at baseline, post intervention and at 6 months follow-up
3. Quality of life is measured using the Stroke Specific Quality of Life Scale and SF-6D at baseline, post intervention and at 6 months follow-up
4. Quality of life and health costs (QALYs) are measured using the EQ5D-5L at baseline, post intervention and at 6 months follow-up
