“…One paper reported on the validation of two screening tests [13], a full version and a short version of the same test, and two tests were evaluated in more than one study [13–18]. Sample sizes ranged from 37 [19] to 194 [16] patients.…”

“…Sample sizes ranged from 37 [19] to 194 [16] patients. Only two studies provided details concerning the type of stroke (i.e., ischemic versus hemorrhagic) [18, 20]. In two papers, information on age and sex of the patient sample was lacking [14, 15], and another three evaluated a rather young cohort (i.e., mean age of 54 [13, 18] and 55 [17] years).…”

“…We included validation studies for nine screening tools: the full and the short version of the Frenchay Aphasia Screening Test (FAST) [13–15], Language Screening Test (LAST) [21], Mississippi Aphasia Screening Test (MAST) [16, 17, 23], the mobile aphasia screening test (also abbreviated as MAST) [18], ScreeLing [20], Sheffield Screening Test for Acquired Language Disorders (SST) [13], Semantic Verbal Fluency (SVF) [22], and Ullevaal Aphasia Screening test (UAS) [19]. Characteristics of the screening tests, including language, subtests, score range, administration time, type of patients, the test was originally designed for, and applicability as a bedside screening tool are given in Table 2.…”

“…In more than half of the studies, patients were not included consecutively [13, 16–18, 21, 22]; and for one study, this information was missing [14]. The diagnostic test that was applied as the gold standard varied from an informal evaluation by an SLT to extensive aphasia test batteries.…”

Screening tests for aphasia in patients with stroke: a systematic review

et al. 2016

Aphasia has a large impact on the quality of life and adds significantly to the costs of stroke care. Early recognition of aphasia in stroke patients is important for prognostication and well-timed treatment planning. We aimed to identify available screening tests for differentiating between aphasic and non-aphasic stroke patients, and to evaluate test accuracy, reliability, and feasibility. We searched PubMed, EMbase, Web of Science, and PsycINFO for published studies on screening tests aimed at assessing aphasia in stroke patients. The reference lists of the selected articles were scanned, and several experts were contacted to detect additional references. Of each screening test, we estimated the sensitivity, specificity, likelihood ratio of a positive test, likelihood ratio of a negative test, and diagnostic odds ratio (DOR), and rated the degree of bias of the validation method. We included ten studies evaluating eight screening tests. There was a large variation across studies regarding sample size, patient characteristics, and reference tests used for validation. Many papers failed to report on the consecutiveness of patient inclusion, time between aphasia onset and administration of the screening test, and blinding. Of the three studies that were rated as having an intermediate or low risk of bias, the DOR was highest for the Language Screening Test and ScreeLing. Several screening tools for aphasia in stroke are available, but many tests have not been verified properly. Methodologically sound validation studies of aphasia screening tests are needed to determine their usefulness in clinical practice.

Speech, communication and language disorders are many and heterogeneous. The modalities of communication affected include spoken understanding and expression, reading, writing and gesture. The three predominant speech and language disorders that can be acquired post-stroke are as follows: AphasiaAphasia is a language disorder affecting understanding of spoken language; the ability to express thoughts verbally, including difficulties with word retrieval (anomia), and sentence production; the ability to read and understand written words and sentences and the ability to write including spelling and structuring written sentences. These difficulties result from damage to the left side of the brain in the majority of people. The extent of impairment to each of the four language domains varies from person to person depending on the locations and extent of neurological damage. Flowers et al. (2013) estimated the incidence of aphasia post-stroke to be 30%. DysarthriaDysarthria is a motor speech disorder resulting from impaired movement of the muscles used for the production of speech. The main parameters of speech are respiration, phonation, resonance, articulation and prosody. One or more of these parameters can be affected leading to reduced speech intelligibility and reduced communication effectiveness. These parameters can be impaired in different ways (for example muscles may be more or less paretic, become hypotonic or hypertonic), and they may each be impaired to different extents. This results in different dysarthria profiles (e.g. Darley et al. 1975). Flowers et al. ( 2013) estimated the incidence of dysarthria post-stroke to be 42%. ApraxiaApraxia of speech (AOS), also known as verbal apraxia or dyspraxia, is also a motor speech disorder. AOS results from a reduction in the ability to co-ordinate the gestures required for speech leading to difficulty producing the right sounds in the right order when speaking. It is characterised by multiple different attempts to articulate words accurately. AOS can occur in isolation, but frequently coincides with expressive aphasia. AOS is acquired with lower frequency following stroke than aphasia or dysarthria.Aphasia, dysarthria and apraxia are not mutually exclusive, and more than one speech and language disorder may need to be treated.Communication impairments affect everyday activity, for example the ability to have conversations, make phone calls, listen to the radio, write letters, construct emails and text messages and read for pleasure, for information or for work. They may also affect the use of sign language for people in the deaf community. In turn, they restrict participation: the ability to carry out pre-stroke employment, loss of roles within the family and community and withdrawal from participating in usual activities both outside of and within the family. These changes affect the wellbeing of both the person with a communication disability and their family/carer with increased frustration, misunderstandings and breakdown/strain on relationships.
