Evaluation of a Theoretical and Experiential Training Programme for Allied Healthcare Providers to Prescribe Exercise Among Persons with Multiple Sclerosis: A Co-Designed Effectiveness-Implementation Study

<b>Background:</b> Multiple sclerosis (MS) is the most prevalent neurological disorder in young adults, characterised by physical, psychological and cognitive dysfunction. Exercise training is a safe management strategy. Healthcare providers (HCPs) acknowledge deficiencies in awareness, counselling strategies, and resources that prevent them from promoting and prescribing this effective treatment. We implemented an online evidence-based educational programme and evaluated the effect, acceptability, appropriateness, and feasibility of the programme in improving HCP confidence, knowledge, and attitudes towards remote exercise prescription to persons with MS. <b>Methods</b>: Physiotherapists and exercise physiologists were recruited and received the educational programme (online theory and 16-week experience of prescribing to persons with MS). Participants' confidence, knowledge and attitudes towards exercise prescription, as well as their professional quality of life, were our primary outcomes-baseline (T1), immediately post-online theoretical learning (T2), post-application with clients (T3; approximately 16 weeks after T2), and at 12-month follow-up (T4). We gathered participants' acceptability, appropriateness, and feasibility evaluation at T2, T3 and T4. We analysed the effect on primary outcomes using generalised linear mixed models, with secondary and evaluative outcomes analysed as counts and qualitative themes. <b>Results</b>: Of 40 participants who provided baseline data, 24 completed the theoretical programme, and 16 completed the experiential programme. Self-confidence improved significantly (|βs| ≥ 1.27, SEs ≤ 0.31, |zs| ≥ 5.28, ps < 0.001), with large effect sizes (percentage change: 256.8-479.4%). Some theoretical domains framework-based domains have improved, such as beliefs about skills to prescribe evidence-based principles. Participants expressed high satisfaction with the programme and showed increased delivery of implementation behaviour change strategies. <b>Conclusions</b>: An online evidence-based education programme for MS care improved HCPs' self-confidence, perceived skills and delivery of evidence-based exercise behaviour-based prescription.
