“…Likewise, patients with chronic aphasia showed long term improvements in communication after transcranial direct current stimulation over the left primary motor cortex combined with language therapy, underlining how the motor system is functionally connected to the language network. 70 This intrinsic link between motor and right-upper limb recovery is also evident in reports of therapies which have targeted the MNS, 69,[71][72][73][74][75][76][77][78][79][80] or made use of music and have shown a benefit for both types of deficit. 59,[81][82][83] For example, observation and repetition training has been used in patients with impaired language function.…”

Stroke is the third leading cause of death in the developed world and the primary cause of adult disability. The most common site of stroke is the middle cerebral artery (MCA), an artery that supplies a range of areas involved in both language and motor function. As a consequence, many stroke patients experience a combination of language and motor deficits. Indeed, those suffering from Broca's aphasia have an 80% chance of also suffering hemiplegia. Despite the prevalence of multifaceted disability in patients, the current trend in both clinical trials and clinical practice is toward compartmentalization of dysfunction. In this article, we review evidence that aphasia and hemiplegia do not just coexist, but that they interact. We review a number of clinical reports describing how therapies for one type of deficit can improve recovery in the other and vice versa. We go on to describe how language deficits should be seen as a warning to clinicians that the patient is likely to experience motor impairment and slower motor recovery, aiding clinicians to optimize their choice of therapy. We explore these findings and offer a tentative link between language and arm function through their shared need for sequential action, which we term fluency. We propose that area BA44 (part of Broca's area) acts as a hub for fluency in both movement and language, both in terms of production and comprehension.

“…The recent identification of a neural network for action observation and imitation of speech (Mashal et al, 2012) provided a theoretical framework for developing new model-based therapies for aphasia, namely IMITATE (Intensive Mouth Imitation and Talking for Aphasia Therapeutic Effects; Lee et al, 2010; Sarasso et al, 2014; Duncan and Small, 2016) and SPEECH ENTRAINMENT (Fridriksson et al, 2012). These interventions aim to improve speech production through action observation and audio-visual feedback via verbal repetition-imitation, which recruits the dorsal and ventral streams in both cerebral hemispheres (Lee et al, 2010; Fridriksson et al, 2012; Sarasso et al, 2014; Chen et al, 2015).…”

Background Performance variability in individuals with aphasia is typically regarded as a nuisance factor complicating assessment and treatment. Objective We present the alternative hypothesis that intra-individual variability represents a fundamental characteristic of an individual’s functioning and an important biomarker for therapeutic selection and prognosis. Methods Nineteen individuals with chronic aphasia participated in a 6-week trial of imitation-based speech therapy. We assessed improvement both on overall language functioning and repetition ability. Further, we determined which pre-treatment variables best predicted improvement on the repetition test. Results Significant gains were made on the Western Aphasia Battery (WAB) Aphasia Quotient, Cortical Quotient, and two subtests, as well as on a separate repetition test. Using stepwise regression, we found that pre-treatment intra-individual variability was the only predictor of improvement in performance on the repetition test, with greater pre-treatment variability predicting greater improvement. Furthermore, the degree of reduction in this variability over the course of treatment was positively correlated with the degree of improvement. Conclusions Intra-individual variability may be indicative of potential for improvement on a given task, with more uniform performance suggesting functioning at or near peak potential.
