ABSTRACT Many neurological disorders, diseases, and traumatic brain injuries result in impairments of volitional movements of the upper limbs, making everyday activities difficult or even impossible for patients. Given the brain’s capacity for neuroplasticity, it seems absolutely imperative that experimental and therapeutic avenues of investigation closely inform one another in the development of treatments. Information from a variety of sources and forms of research can be considered with the aim of developing the most efficacious therapies and rehabilitative treatments possible. The present review focuses on some of the experimental findings from research into the planning and production of bimanual actions. A model of conceptual unifying representations is then presented to encompass a range of findings in the literature. Issues illuminated by the findings and model, particularly those which seem of relevance to therapeutic developments, are emphasised. The overarching aim of this review is to increase communication across domains, with the hope of improving existing therapies and promoting the development of new ones.
