Schuell's Stimulation Approach to Rehabilitation (Expressive Language)
Summary: More of a school of thought in aphasia rehabilitation than a specific therapy, Schuell’s Stimulation Approach highlights the central importance of auditory processing for all aspects of language ability and targets this in order to promote reorganisation of the brain (Coelho et al., 2008). It encompasses a wide variety of tasks that provide intensive auditory stimulation e.g. following directions, spoken word to picture matching and word repetition, as well as many tasks that also require additional processes (e.g. word retrieval, sentence formulation, reading and writing). Tasks are manipulated so as to vary the processing load, e.g. progressively longer commands, increased number of pictures in spoken word to picture matching tasks. A range of other therapy approaches discussed in this app could also be considered stimulation approaches, e.g. Melodic Intonation Therapy and Visual Action Therapy (Helm-Estabrooks & Albert, 2004).
Example:
The following are examples of tasks that, in addition to auditory processing, target word retrieval or sentence formulation. Therapy tasks that more specifically stimulate spoken language comprehension, reading or writing skills are also available (see links at bottom of this page).
As noted in Coelho et al. (2008), the therapist should start with tasks that the client is able to engage with but experiences some difficulty (i.e. 60-80% accurate responses prior to treatment). As clients become more accurate at a given task (i.e. when the client is 90% accurate), the therapist should gradually increase the processing load on the client by varying factors such as (e.g. increasing the complexity of sentence structure the client is prompted to repeat). Schuell et al. (1964) advise eliciting as many responses as possible during a session and state that incorrect responses should be responded to with increased auditory stimulation (e.g. additional cues from the therapist) rather than corrections. Many of these tasks can be made more/less demanding by varying the speed of delivery and the number of phonological, semantic and visual cues provided to the client. Tasks should involve repetitive presentation of stimuli and each stimulus should prompt a response (Coelho et al., 2008).

Evidence Base: Given the widespread and varied use of Schuell’s Stimulation Approach, it is challenging to give an accurate summary of studies into its effectiveness. Detailed below are some examples of studies that have used this approach.
Basso et al. (1979) investigated the effects of a stimulation approach for 281 participants with aphasia (162 treated, 119 control) over at least six months of therapy (at least 3 sessions per week), finding that it had a positive effect on language rehabilitation outcomes across all modalities. Factors such as the length of time since onset and severity of aphasia negatively influenced outcomes.
Wertz et al. (1989) delivered wide-ranging, personalised stimulation therapy to 121 participants with a range of aphasia types for 12 weeks. This study found that participants who received therapist-led stimulation therapy made significantly more progress on language measures than untreated participants.
Poeck et al., (1989) provided an intensive stimulation approach (9 hours weekly for 6-8 weeks) to 68 participants with aphasia and contrasted their gains with control participants from an earlier study (so as to determine whether gains were likely to be related to therapy or spontaneous recovery). This approach led to significant improvements in the performance of participants in the early stages of aphasia (i.e. 1-4 months post stroke) on the Token Test and a repetition task.
