“…The inclusion of people with severe aphasia should be noted. Unlike the current study, the majority of participants (33/55) in a recent systematic review of SFA studies were fluent and had mostly mild aphasias (Conduction and Anomic), and only 5/55 participants had severe aphasia (Efstratiadou et al, 2018). In contrast, in our study 19/38 (50%) of participants had severe aphasia.…”

“…This is an important finding that adds to current knowledge on maintenance of gains after SFA. In a recent systematic review of SFA studies (Efstratiadou et al, 2018), maintenance was reported for 58.18% of participants, but most of the included studies assessed maintenance in the short term, with only 2/21 studies assessing maintenance at 3 months or longer post therapy and only 1/4 participants in these two studies showing a positive effect (Davis & Stanton, 2005;Kristensson, Behrns & Saldert, 2015). Lastly, significant others perceived an improvement on participants' functional communicational skills at the follow-up assessment.…”

“…According to the spreading activation theory of semantic processing (Collins & Loftus, 1975), activating the semantic network surrounding the target should activate the target itself, thus facilitating retrieval of the word. Evidence from two systematic reviews and metaanalyses suggests that SFA leads to positive outcomes on naming despite variability in treatment procedures, dosage, and duration; with limited generalization to untrained items and connected speech (Efstratiadou, Papathanasiou, Holland, Archonti & Hilari, 2018;Oh, Eom, Park & Sung, 2016). None of the included studies in these meta-analyses were controlled trials.…”

Background:Word finding difficulty is one of the most common features of aphasia. Semantic Features Analysis (SFA) directly aims to improve word finding in people with aphasia. Evidence from systematic reviews suggests that SFA leads to positive outcomes, yet the evidence comprises single case studies and case series. There is a need to evaluate the efficacy of SFA in controlled group studies/trials. Aims:To evaluate the efficacy of Elaborated Semantic Feature Analysis (ESFA) for word finding in people with aphasia. We investigated: (a) the efficacy of ESFA versus a delayed therapy/control, (b) the efficacy of two therapy approaches-individual versus a combination of individual and group therapy. Methods and procedures:We ran a multi-centre, quasi-randomised controlled trial, nested in a larger study (Thales-Aphasia). Participants were recruited from community settings. They had to be people with aphasia due to stroke at least four months postonset. Participants were randomized to individual vs combination vs delayed therapy/control groups. Both therapy groups had three hours of ESFA per week for 12 weeks. Delayed therapy/control group had no intervention for 12 weeks and were then randomized to either individual or combination therapy. The primary outcome was confrontation naming. Secondary outcomes were the Boston Naming Test, Discourse, the Functional Assessment of Communication Skills for adults (ASHA-FACS), the Stroke and Aphasia Quality of Life scale (SAQOL-39g), the General Health Questionnaire-12 item, and the EQ-5D. Outcomes and Results:Of the 72 participants of the Thales-Aphasia project, 58 met eligibility criteria for speech-language therapy and 39 were allocated to ESFA. The critical p-value was adjusted for multiple comparisons (.005). For the therapy versus control comparison, there was a significant main effect of time on the primary outcome (p<.001, η 2 p=.42) and a significant interaction effect (p=.003, η 2 p=.21). An interaction effect for the SAQOL-39g (p=.015, η 2 p=.11) and its psychosocial domain (p=.013, η 2 p=.12) did not remain significant after Bonferroni adjustment. For the individual versus combination ESFA comparison, there were significant main effects of time on the primary outcome (p<.001, η 2 p=.49), the BNT (p<.001, η 2 p=.29) and the ASHA-FACS (p=.001, η 2 p=.18). Interaction and group effects were not significant. Conclusion: Though underpowered, this study provides evidence on the efficacy of ESFA to improve word finding in aphasia, with gains similar in the two therapy approaches.Trial registration: ISRCTN71455409, https://doi.

“…As well as the qualitative reviews discussed above, three systematic reviews of verb treatments have been conducted since 2013 (Efstratiadou, Papathanasiou, Holland, Archonti, & Hilari, 2018;Maddy, Capilouto & McComas, 2014;Rose, Raymer, Lanyon & Attard, 2013) and all of these contribute to our understanding of the effectiveness of verb treatments. However, none of these encompassed all researched treatments for verbs or included an evaluation of treatment fidelity.…”

“…However, none of these encompassed all researched treatments for verbs or included an evaluation of treatment fidelity. Maddy et al (2014) and Efstratiadou et al (2018) both conducted systematic reviews restricted to Semantic Feature Analysis (SFA) treatment, including studies that used SFA to treat nouns or discourse, as well as those which targeted verbs. The methodological quality of the reviewed studies was evaluated using the Single Case Experimental Design (SCED) Scale (Tate et al, 2008) and effect sizes were calculated (using Cohen's d and benchmarks specified by Beeson and Robey (2006)) to evaluate the effectiveness of SFA.…”

Purpose Aphasia research demonstrates increasing interest in the treatment of verb retrieval deficits. This systematically conducted scoping review reports on the level and fidelity of the current evidence for verb treatments; on its effectiveness regarding the production of trained and untrained verbs, functional communication, sentences, and discourse; and on the potential active ingredients. Recommendations to guide clinical decision making and future research are made. Method The computerized database search included studies from January 1980 to September 2018. The level of evidence of each study was documented, as was fidelity in terms of treatment delivery, enactment, and receipt. Studies were also categorized according to the treatment methods used. Results Thirty-seven studies were accepted into the review, and all but 1 constituted a low level of evidence. Thirty-three studies (89%) described treatment in sufficient detail to allow replication, dosage was poorly reported, and the fidelity of treatment was rarely assessed. The most commonly reported treatment techniques were phonological and semantic cueing in 25 (67.5%) and 20 (54%) studies, respectively. Retrieval of trained verbs improved for 80% of participants, and improvements generalized to untrained verbs for 15% of participants. There was not sufficient detail to evaluate the impact of treatment on sentence production, functional communication, and discourse. Conclusions The evidence for verb treatments is predominantly of a low level. There are encouraging findings in terms of treatments being replicable; however, this is tempered by poor monitoring of treatment fidelity. The quality of verb treatment research would be improved by researchers reaching consensus regarding outcome measures (including generalization to, e.g., sentences and discourse) by manualizing treatment to facilitate implementation and exploring the opinions of participants. Finally, while treatment is largely effective in improving production of trained verbs, lack of generalization to untrained items leads to the recommendation that personally relevant verbs are prioritized.

Neurologic manifestations associated with a coronavirus disease 2019 (COVID‐19) diagnosis are common and often occur in severe and critically ill patients. In these patients, the neurologic symptoms are confounded by critical care conditions, such as acute respiratory distress syndrome (ARDS). Patients with dual diagnoses of COVID‐19 and neurologic changes such as myopathy, polyneuropathy, and stroke are likely at a higher risk of experiencing deficits with swallowing, communication, and/or cognition. Speech‐language pathologists are an integral part of both the critical care and neurologic disorders multi‐disciplinary teams, offering valuable contributions in the evaluation, treatment, and management of these areas. Patients in intensive care units (ICUs) who require mechanical ventilation often experience difficulty with communication and benefit from early speech‐language pathology intervention to identify the most efficient communication methods with the medical team and caregivers. Moreover, patients with neurologic manifestations may present with cognitive‐linguistic impairments such as aphasia, thereby increasing the need for communication‐based interventions. Difficulties with voice and swallowing after extubation are common, often requiring frequent treatment sessions, possibly persisting beyond ICU discharge. After leaving the ICU, patients with COVID‐19 often experience physical, cognitive, and mental health impairments collectively called post‐intensive care syndrome. This is often a lengthy road as they progress toward full recovery, requiring continued speech‐language pathology treatment after hospital discharge, capitalizing on the principles of neuroplasticity.
