Digital health technologies (DHTs) are increasingly used in physical stroke rehabilitation to support individuals to successfully engage with the frequent, intensive, and lengthy activities required to optimise recovery. Despite this, little is known about behaviour change within these interventions. This scoping review aimed to identify if, and how behaviour change approaches (i.e., theories, models and frameworks, and techniques to influence behaviour) are incorporated within physical stroke rehabilitation interventions that include a DHT. 
This scoping review found that despite most DHTs being assumed to promote engagement in rehabilitation, very few studies of DHT-based physical stroke rehabilitation overtly utilised any form of behaviour change approach. From those studies that did consider behaviour change, most did not report robust underpinning theory. Future development and research of DHT-based rehabilitation needs to explicitly articulate how using DHTs may support the behaviour change required for optimal engagement in physical rehabilitation as well as establish their effectiveness. This understanding is likely to support the realisation of the transformative potential of DHTs in rehabilitation.
