Web-based physical activity intervention for people with progressive multiple sclerosis: application of consensus-based intervention development guidance

Objectives People with progressive multiple sclerosis (PwPMS) report that they recognise the benefits of activity on their physical and psychological health but need support to achieve goals. We aimed systematically develop a theoretically informed intervention would enable PwPMS more readily engage in regular activity. Design used an mapping approach inform development. Setting conducted semistructured interviews families/carers physiotherapists recruited from secondary care settings. Participants Fourteen Expanded Disability Status Scale score between 6 8 7 13 1 physiotherapy technician participated. Results Interview data suggested development supportive coaching relationships could promote ability desirable achievable plan. These interview prototype ‘Lifestyle Exercise Activity Package for Multiple Sclerosis’ (LEAP-MS) consisting secure multiuser web-based platform (with education suite, interactive components enabling selection exercises, goal setting logging), up six flexible face-to-face or sessions remote via embedded messaging function all together draw specific theory-based methods behaviour change, namely active learning, reinforcement, modelling, feedback, facilitation, guided practice. Implementation is within accessible participants, trained researchers. Conclusions have followed inclusive, systematic transparent process LEAP-MS enables detailed description components, context guiding principles ongoing evaluation. Importantly, expressed autonomy developing plans. This has been achieved through embedding self-management design delivery intervention.
