“…However, in the context of age-related or acquired losses, the term dual sensory impairment (DSI) has been more commonly used (Wittich, Southall, Sikora, Watanabe, & Gagne, 2013). The population prevalence of DSI is estimated to be around 0.74 to 5 per cent (Dawes et al, 2014; Kwon, Kim, Kim, Kwon, & Yu, 2015; Swenor, Ramulu, Willis, Friedman, & Lin, 2013), and dramatically increases up to 20–37 per cent when examining sub-populations of older adults (e.g., Cimarolli & Jopp, 2014; Roets-Merken, Zuidema, Vernooij-Dassen, & Kempen, 2014; Yamada et al, 2015). Among individuals who access rehabilitation services for DSI, between 69 and 85 per cent are over the age of 65 (Dammeyer, 2013; Wittich, Watanabe, & Gagne, 2012).…”
