Secondary Prevention of Stroke: Study Protocol for a Telehealth-Delivered Physical Activity and Diet Pilot Randomized Trial (ENAbLE-Pilot)

Cerebrovasc Dis. 2021;50(5):605-611. doi: 10.1159/000515689. Epub 2021 Apr 23.


Background: Increasing physical activity (PA) and improving diet quality are opportunities to improve secondary stroke prevention, but access to appropriate services is limited. Interventions co-designed with stroke survivors and delivered by telehealth are a potential solution.

Aim: The aim of this study is to test the feasibility, safety, and potential efficacy of a 6-month, telehealth-delivered PA and/or dietary (DIET) intervention.

Methods: Pilot randomized trial. 80 adults with previous stroke who are living at home with Internet access and able to exercise will be randomized in a 2 × 2 factorial (4-arm) pilot randomized, open-label, blinded outcome assessment trial to receive PA, DIET, PA + DIET, or control interventions via telehealth. The PA intervention aims to support participants to meet the minimum recommended levels of PA (150 min/week moderate exercise), and the DIET intervention aims to support participants to follow the AusMed (Mediterranean-style) diet. The control group receives usual care plus education about PA and healthy eating. The co-primary outcomes are feasibility (proportion and characteristics of eligible participants enrolled and proportion of scheduled intervention sessions attended) and safety (adverse events) at 6 months. The secondary outcomes include recurrent stroke risk factors (blood pressure, physical activity levels, and diet quality), fatigue, mood, and quality of life. Outcomes are measured at 3, 6, and 12 months.

Conclusion: This trial will produce evidence for the feasibility, safety, and potential effect of telehealth-delivered PA and DIET interventions for people with stroke. Results will inform development of an appropriately powered trial to test effectiveness to reduce major risk factors for recurrent stroke.
