Description

Design

The present study will be a controlled trial without randomisation. This is considered appropriate by the research team given the potential for participants of the exercise group to experience improved health outcomes compared with those assigned to a control group (receiving usual clinical care, who elect not to attend exercise classes). Accordingly, all individuals diagnosed with stroke from Hampshire Hospitals NHS Foundation Trust, who meet inclusion criteria (i.e. eligible to engage in a stroke rehabilitation programme) will be presented with an equal opportunity to attend low-cost, community-based exercise classes. Health-related quality of life, with researchers considering participation against various measures of physical and psycho-social health outcomes will be assessed at baseline, post-intervention (following possible engagement in 12 weeks of exercise classes) and at 6-month follow-up. Attendance to exercise classes will be optional but will be monitored to assess exercise adherence. Participants electing not to attend exercise classes will form a control group, providing evidence of the usual care pathway, and will also be asked to attend the post-intervention and 6-month follow-up assessment.

Exercise classes will be provided through the Health Enhancing Lifestyle Programme (HELP) Hampshire Stoke Clinic. The HELP clinic is a community-based initiative that signposts and provides individuals who have experienced stroke and/or TIA to various accessible and affordable exercise and educational opportunities and is led by the University of Winchester in collaboration with the Hampshire Hospitals NHS Foundation Trust (HHFT) and Hobbs Rehabilitation, a specialist, independent, neuro-physiotherapy provider. As the HELP Hampshire Stroke Clinic provides a service to the stroke community alongside the usual care pathway, some individuals referred to the clinic may choose to participate in the exercise classes but not to participate in the study. This is a fundamental right of the individual. Such individuals will not be disadvantaged in anyway as it will not impact the opportunity for them to access the exercise classes, nor will it affect the nature of the exercises or any other part of the service provided by the HELP Hampshire Stoke Clinic.

The research team have discussed the design of the present study with the clinical team at HHFT, including stoke consultants, occupational therapists and physiotherapists, and neuro-physiotherapists from Hobbs Rehabilitation. The study has also been discussed at a Patient and Public Involvement (PPI) meeting, and with people who are currently engaging in the HELP Hampshire Stroke Clinic. The project has been discussed with Prof Maria Stokes and Dr Danielle Lambrick from the School of Health Sciences at the University of Southampton.

Recruitment

Potential participants will initially be identified by the healthcare team at Hampshire Hospitals NHS Trust(i.e. stroke consultants, occupational therapists, physiotherapists), according to study inclusion/exclusion criteria. The clinical team will gain written consent from potential participants for their contact details to be provided to the research team at the University of Winchester (Dr James Faulkner) who will then contact patients directly to discuss their potential participation.

As described above (Design), the research team will make every effort to provide all participants a fair and equal opportunity to participate in all available exercise classes so as to avoid the introduction of any bias relating to potential demographic or socioeconomic differences.

Informed Consent:

Participants will be provided with a study information sheet which outlines their possible involvement and will have opportunities to discuss the study with the research team prior to making a decision as to whether to participate or not. Each patient will have had sufficient time (>24-hours) to read the information sheet and discuss their options with significant others, and will be able to ask questions to the research team both by phone prior to attending their first assessment visit and upon arrival to the Physiology Laboratory at the University of Winchester before providing voluntary written consent for participation in this study. Participants will be reminded that attendance to each assessment visit is compulsory but that attendance to any of the exercise classes is optional and that they can withdraw from the study at any time and without repercussion of any kind.

The research team have met with Speech and Language therapists at HHFT to discuss potential issues concerning consent in patients with aphasia. Patients who are not able to fully comprehend the nature of the study and involvement in the HELP Hampshire Stroke Clinic will be excluded from participation.

Risks, burdens and benefits:

Participants may experience mild discomfort while providing a fingertip blood sample and during analysis of blood pressure (measured at the upper-left arm) during the baseline, post-intervention and 6-month follow-up assessment. Participants will be fully briefed about both tests and will have likely experienced both procedures during usual clinical care.

Baseline and 12- and 36 week follow-up assessments Participants will complete an online baseline assessment whereby they will complete a general health history questionnaire and a series of quality of life, physical activity and psycho-social questionnaires (see outcome measures for further information). Participant demographics (height, weight) will be recorded, while participants will also complete a sit-to-stand test (see outcome measures for further information). All measures will be repeated at the 12 and 36 week follow-up assessment.

On completion of the baseline assessment, participants will be able to attend the exercise classes.

Exercise classes During the exercise classes, individuals will be required to exercise in bouts of intensities up to their self-selected maximum which may result in discomfort including fatigue and nausea. To minimise this risk, periods of rest will be scheduled, and plain water will be available ad libitum during all functional trials and exercise classes. Researchers who are first aid trained will be in attendance for all sessions and will have access to an automated external defibrillator and mobile phone for emergency use.

As part of the study, participants will be invited to attend low-cost, community-based exercise clinics led by specialist Physiotherapists, and will continue to have access to these classes after their participation in the research study has ended. Exercise classes will be delivered in person (face-to-face) or online. All exercise classes will last 60 minutes, with a minimum of one face-to-face and one online exercise class available to participants each week. Both face-to-face and online exercise classes will include a range of seated and standing resistance and aerobic exercises (e.g., sit-to-stand, step-ups, bicep curls, walking).

Costs: Although the HELP Hampshire Stroke Clinic is a not-profit project, attendees pay £5 per exercise class to allow us to cover the costs of practitioner hire and venue hire. Participants incur no costs for the baseline, post-intervention and 6-month follow-up assessments.
