Initiatives to increase physical activity (PA) are most effective when combined with behavior change strategies (BCS). However, this is not routinely done and perhaps can be attributed to health care professionals' (HCP) lack of confidence and understanding of how to best apply BCS. This review aimed to identify and synthesize the existing literature describing methods used to train HCP to deliver BCS for PA promotion for individuals living with neurological conditions. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Eight databases were searched for articles describing how HCP were trained on BCS targeting PA and/or exercise for neurological pathology. Two researchers independently screened abstracts and used third-party consensus when needed. Studies must have described the planning/implementation of BCS targeting PA in adults with neurological disorders, with interventions delivered by a HCP. A data extraction table based on the study objective and the Cochrane Consumers and Communication Review Group's data extraction template was used. Risk of bias was assessed using the Quality Assessment Tools for Quantitative and Qualitative Studies. Included studies were also evaluated using the Workgroup for Intervention Development and Evaluation Research (WIDER) recommendations for reporting behavior change intervention content. Extraction and evaluation of risk of bias were completed independently by two researchers. Data were synthesized according to a who, what, when, and how approach. The search yielded 2,616 articles after duplicates removed, with 13 articles, representing eight unique interventions in individuals with spinal cord injury, stroke, multiple sclerosis, and Parkinson's disease included. Methodological quality ranged from strong to weak. Methods used to increase HCP knowledge and use of BCS were heterogeneous. Common training features included multiple resources, multiple sessions, expert input, and ongoing support, but a lack of evaluation of training effectiveness. The BCS were based on Social Cognitive Theory in seven interventions. Physiotherapists were the most common HCP trained. There was considerable variety in how HCP were trained to use BCS and a lack of evaluation of training effectiveness. Future work should include more description of the content and structure of HCP training and a direct measure of effectiveness. Researchers should consider implementation strategies during development and reporting of behavior change interventions. This review was not registered with PROSPERO.
