Treating number transcoding difficulties in a chronic aphasic patient

Benefits of a targeted rehabilitation of number transcoding in secondary acalculia: A single‐case experimental design

“…More recently, Ardila and Rosselli (2019) identified only three publications on the subject of acalculia rehabilitation. To date, only three of the publications identified in these two reviews deal with transcoding rehabilitation in the context of acquired brain injury (Ablinger et al, 2006;Deloche et al, 1989Deloche et al, , 1992. They demonstrate a positive effect of their interventions.…”

“…The three published studies describing rehabilitation of number transcoding disorders (Ablinger et al, 2006;Deloche et al, 1989Deloche et al, , 1992) are restorative, intensive, all refer to the asemantic transcoding model (Deloche & Seron, 1982, 1987) and aim at re-teaching impaired and lost knowledge (Ablinger et al, 2006) or re-automating these processes. This restorative perspective is directly related to the specificities of verbal and Arabic numerals.…”

“…The only available information is that the interventions are divided into five periods. Ablinger et al (2006) report an intervention lasting 8 weeks, with five sessions of 45 min per week. The definition of the intensive nature of these treatments therefore varies according to the studies.…”

“…In total, 616 items were reviewed during part A of the intervention, and 480 items during part B. In Ablinger et al (2006), between 20 and 30 items were trained at each session, depending on the patient's abilities.…”

“…The second study also relies on colours and visual aids. Ablinger et al (2006) use visual (colours and tables) but also phonemic, verbal automatisms and repetition to help the patient. The systematic use of colours in each of the interventions is explained by the privileged neuroanatomical link between colours and the representation of quantities (Domahs et al, 2004).…”
