Massed sentence repetition training can augment and speed up recovery of speech production deficits in patients with chronic conduction aphasia receiving donepezil treatment

The links between short-term/working memory functioning and language in aphasia are generally acknowledged. These strongly indicate the need to incorporate assessment of short-term/working memory functioning for people with aphasia. While the supportive evidence for treatment is growing and appears to highlight the benefits of including short-term/working memory in aphasia treatment, the quality of the evidence in its current state is poor. However, because of the clinical needs of people with aphasia and the prevalence of short-term/working memory impairments, incorporating related treatments through practice-based evidence is advocated.

“…In this situation, it may be difficult to find suitable, laboratory measures for establishing the specificity of WM training. A way to circumvent these difficulties is to use control treatments instead of control tasks, as has been done by Berthier et al (2014). This strategy is optimal for patients in which the WM deficit is the only remaining deficit as only the WM treatment should lead to improved WM performance.…”

“…A final study used a verbal repetition treatment procedure for treating repetition and verbal WM impairment in conjunction with pharmacological treatment in three patients with conduction aphasia (Berthier et al, 2014). Importantly, this study is one of the few studies comparing the target treatment to a control treatment which consisted in distributed multi-level speech language therapy.…”

“…This moderate evidence for control treatment effects is partially driven by studies that targeted training of executive and attentional aspects of WM which led to an aggregated mean control treatment effect size of 1.14 (range: 0.00-3.45) versus 0.73 (range: −0.7-5.66) for the other intervention strategies. Treatment effects on control measures were also driven by the control treatment in the study by Berthier et al (2014) which targeted many different language components and processes at the same time and which already led to relatively large treatment effects on verbal WM and sentence repetition measures before implementation of the WM treatment.…”

A B S T R A C TWorking memory (WM) is a frequent and long-lasting deficit in patients with aphasia. Progress has been made in our understanding of the nature of WM impairment, by considering deficits at the level of maintenance of item and serial order information (short-term memory), deficits at the level of attentional control, and their complex interactions with language impairment. However, WM treatment studies in aphasic patients remain scarce. This theoretical and quantitative review of 15 single-case treatment studies (24 patients) reveals that WM treatment in aphasic patients is associated with robust near transfer effects and smaller far transfer effects. WM treatment can also raise verbal WM capacity to normal range performance levels. The specificity of WM treatment is more difficult to establish as control tasks/treatments are associated with treatment effects of comparable size as far transfer effects. Existing treatments cover phonological maintenance and control of attention components of WM but do not target difficulties at the level of item interference or serial order processing. In order to improve the specificity of WM treatments, future studies should define WM impairment and treatment targets in a more precise and theoretically informed manner. Also, although the vast majority of reviewed studies meet minimal methodological requirements for single case experimental designs, the use of a larger number of baseline, treatment and control measures is recommended. Finally, publication of treatment studies with negative outcomes should be encouraged as it is currently difficult to estimate the impact of publication bias on observed treatment effects.

“…In a case series study, Berthier et al (2014) compare the benefit provided by two therapies (conventional speech language therapy versus massed sentence repetition therapy) in three stroke patients with chronic conduction aphasia receiving donepezil treatment. They found that both interventions significantly improved speech production deficits relative to baselines assessments, but outcomes after massed sentence repetition therapy were better than the conventional regime.…”
