“…Although research into treatment duration does offer some insight into the highly heterogeneous content of conventional arm physiotherapy (PT) and occupational therapy (OT) after stroke, duration alone is inadequate in determining treatment dose and composition (Ballinger et al, 1999). Therefore, more knowledge about the content of PT and OT during treatment sessions (relating to, e.g., goals and activities, treatment time, detailed schedule, and intensity) is necessary in order to replicate interventions (Hoffmann et al, 2014), to provide insight into the specific types of interventions (Hunter, Crome, Sim, Donaldson, & Pomeroy, 2006;Jarvis & Reid, 2014) and their characteristics that influence treatment success (Ballinger et al, 1999;Parry, Lincoln, Appleyard, & Words, 1999;Tyson & Selley, 2004;DeJong, Horn, Conroy, Nichols, & Healton, 2005). Further, treatment type and dose are considered potential sources of variability to be included in predictive models (Stinear, 2010).…”
