Blue Prescription: A single-subject design intervention to enable physical activity for people with stroke

Abstract

Background/Aims: Adherence to long-term physical activity is low in stroke survivors despite evidence supporting the benefits of regular physical activity on health and wellbeing. The aims of this single-subject design study were to: i) determine whether Blue Prescription, a physiotherapy approach to increase physical activity, enabled adults with chronic stroke living in the community to engage in a physical activity of their choice for three months; ii) explore the benefits of the Blue Prescription intervention on self-reported quality of life, physical function and self-efficacy. Methods: A multiple-participant, two-phase (baseline followed by treatment) single-subject design study was repeated with adults (n=5) with chronic stroke. The time of baseline testing, follow-up outcome measurement and Blue Prescription visits were randomly assigned to each participant. Due to randomisation, the baseline phase spanned four to six weeks. The intervention phase had a duration of three months. Engagement in physical activity was recorded in a physical activity diary. Secondary outcome measures used included the European Quality of Life Scale, Stroke Impact Scale and Stroke Self-Efficacy Questionnaire, which were completed at 15 random intervals over four and a half months. Results: All five participants maintained engagement in their chosen activity for three months. Participant 2 mostly showed significant improvements in the secondary outcome measures (p<0.05), while participant 4 showed a significant decline in the European Quality of Life Scale (p<0.05). No other significant results were found, although observable trends in secondary outcome measure scores were present. Conclusions: Blue Prescription appears feasible for engaging chronic stroke survivors in physical activity, although its effects on quality of life, physical function and self-efficacy are variable.
