Rekindling the love of books - a pilot project exploring whether e-readers help people to read again after a stroke

Background E-readers may facilitate reading in aphasia through “aphasia-friendly” features such as altering text size and formatting (Worrall et al, 2005), and text-to-speech functions. However, no previous research has examined whether e-readers help people with aphasia to read. Aims This project explored: • whether people with aphasia can learn to use e-readers following a brief period of training • whether e-reader training improves reading comprehension • whether e-readers increase participation in and enjoyment of reading activities Method and procedures In phase one, available e-readers were compared using an expert evaluation against a set of criteria, to identify the model with optimum accessibility features and fewest potential barriers. The Kindle Keyboard 3G TM (Amazon) was selected for trialling in phase two. Four people with self-reported reading difficulties post-stroke participated in phase two. All had mild or mild-moderate aphasia. Four one-hour training sessions aimed to trial accessibility features, identify helpful features, and teach independent operation of these. A repeated measures design was used. Outcome measures assessed reading comprehension (Gray Oral Reading Tests, Bryant & Wiederholt, 2001) and confidence and emotions associated with reading (Reading Confidence and Emotions Questionnaire, Cocks et al., 2013). Matched texts were used to compare reading comprehension using printed texts and the e-reader. Usability evaluations explored independence in e-reader use and acceptability of the technology. Participation in reading activities and reading enjoyment were explored using qualitative exit interviews. Outcomes and results Participants’ reading comprehension on the Kindle, as measured by the GORT-4, did not improve following training and did not exceed comprehension of printed texts. However, reading confidence improved significantly for three of the participants (RCEQ: p<.05, p<.01 and p<.005). Analysis of exit interviews and usability evaluations indicates that three out of four participants preferred reading on the Kindle to printed texts. These participants read more frequently on the Kindle than they had done before the training, and the technology enabled them to access more challenging texts (e.g. novels). They appreciated different features of the Kindle. Two participants experienced difficulties operating the technology, one of whom would have benefited from a longer training period. Conclusions This pilot study suggests that a short block of e-reader training led to improvements in reading confidence, participation and enjoyment. E-readers were not shown to enhance reading comprehension. Larger-scale investigations are warranted to further investigate whether and how e-readers facilitate reading for people with aphasia

A comparison of remote therapy, face to face therapy and an attention control intervention for people with aphasia: A quasi-randomised controlled feasibility study

Objective: To test the feasibility of a Randomised Controlled Trial comparing face to face and remotely delivered word finding therapy for people with aphasia Design: A quasi-randomised controlled feasibility study comparing remote therapy delivered from a University lab, remote therapy delivered from a clinical site, face to face therapy and an attention control condition Setting: A University lab and NHS outpatient service Participants: Twenty-one people with aphasia following left hemisphere stroke Interventions: Eight sessions of word finding therapy, delivered either face to face or remotely, were compared to an attention control condition comprising eight sessions of remotely delivered supported conversation. The remote conditions used mainstream video conferencing technology. Outcome measures: Feasibility was assessed by recruitment and attrition rates, participant observations and interviews, and treatment fidelity checking. Effects of therapy on word retrieval were assessed by tests of picture naming and naming in conversation. Results: Twenty-one participants were recruited over 17 months, with one lost at baseline. Compliance and satisfaction with the intervention was good. Treatment fidelity was high for both remote and face to face delivery (1251/1421 therapist behaviours were compliant with the protocol). Participants who received therapy improved on picture naming significantly more than controls (mean numerical gains: 20.2 (remote from University); 41 (remote from clinical site); 30.8 (face to face); 5.8 (attention control); p <.001). There were no significant differences between groups in the assessment of conversation. Conclusions: Word finding therapy can be delivered via mainstream internet video conferencing. Therapy improved picture naming, but not naming in conversation

Speech and Language

This chapter introduces speech and language from a clinical speech and language therapy perspective. It describes key challenges that can impact upon speech and language with a focus on the needs of individuals with aphasia, an acquired language disorder. The spe-cific impact that aphasia may have upon Web accessibility is dis-cussed with reference to existing work which illuminates what we currently do and do not know about speech, language and Web ac-cessibility. The authors provide guidance for accommodating the needs of users with aphasia within the design of Web interactions and propose future directions for development and research

Using Voice Recognition Software to improve communicative writing and social participation in an individual with severe acquired dysgraphia: an experimental single case therapy study

Background Two previous single-case studies have reported that voice recognition software (VRS) can be a powerful tool for circumventing impaired writing in aphasia (Bruce et al, 2003; Estes & Bloom, 2011). However, these studies report mixed results regarding transfer of skills to functional tasks, such as emailing. Method A single-case therapy study was conducted with “Stephen”, a 63 -year old man with fluent aphasia and severe acquired dysgraphia and dyslexia limiting his social participation and ability to return to work. Treatment consisted of 16 one-hour sessions. Stephen was trained to use Dragon NaturallySpeakingRTM VRS to assist writing and Read+WriteGoldRTM text-to-speech software to assist reading, and to develop computer skills required to use email. Outcome measures evaluated writing efficiency and communicative effectiveness, the functional impact of the intervention, and changes in participation. Results Training produced significant gains in the efficiency and communicative effectiveness of Stephen’s writing, despite his underlying writing impairment remaining unchanged. Gains generalised to everyday functional communication, leading to increased social participation with Stephen undertaking a wider range of social activities and increasing his social network following treatment. Gains were maintained at follow-up assessment. Discussion Results indicate that a relatively short training period with assistive technologies achieved extensive generalisation to independent, functional communicative writing. Indeed, for this case, VRS training may have exceeded the degree of improvement in functional text writing that could have been achieved through impairment therapy, since gains were not limited to treated vocabulary. Some challenges were encountered in training Stephen to use VRS but, through adaptations to the training process, were largely overcome. Importantly, regaining independent writing skills resulted in profound and life-changing improvements to social participation. This may have resulted in Stephen reconnecting with important aspects of his pre-stroke identity, and improving his self-esteem. Conclusion This case adds to a small evidence base indicating that training in the use of VRS, in combination with text-to-speech software, may be an effective way to address writing impairments in chronic aphasia for individuals with relatively well-preserved spoken output. Not only can these technologies improve the efficiency and communicative effectiveness of writing, they can also lead to significant gains in functional communication and social participation. Further research is needed trialing this approach with a larger group of people with aphasia

Treatment fidelity of technology-enhanced reading therapy (CommuniCATE) for people with aphasia

BACKGROUND: Treatment fidelity (TF), that is, the degree to which the treatment delivery has adhered to protocol, is an important aspect of establishing treatment validity and reliability. Research has shown that establishing TF is only done in a small percentage of aphasia treatment studies. AIMS: This project supports the work of the CommuniCATE study, which explored the benefits of technology-enhanced aphasia therapy on participants' reading, writing, speech and conversation skills. It examines the TF of the Reading strand of the CommuniCATE project by assessing whether the therapy adhered to the protocol. The following research questions were asked: Does treatment delivery adhere to treatment protocol? Does the degree of TF vary according to the person delivering the therapy (i.e. student therapist or qualified therapist)? Does the degree of TF vary over time (early treatment sessions compared with later treatment sessions)? Was the checklist tool reliable? METHODS & PROCEDURES: This study assessed the fidelity of 38 retrospective video recordings of therapy. It used a checklist measure of criteria to which the delivery of the sessions should adhere, and against which the sessions were rated. Participants were the people with aphasia receiving therapy, the students and qualified speech and language therapists delivering therapy, and the independent raters assessing the sessions. A sample of sessions was randomly chosen, including sessions delivered by qualified therapists and by students, and sessions from different time points in the treatment process. The fidelity was rated by the first author, and the fidelity rating calculated as a percentage. Comparisons in fidelity scores for the different variables were drawn using Mann-Whitney tests. The reliability of the checklist was assessed through inter and intra-rater reliability testing, and the results were analysed using Kappa statistics. OUTCOMES & RESULTS: High fidelity was found across all therapy conditions with a mean score of 98.2%. Fidelity scores were not affected by the administrator of therapy; sessions delivered by qualified and student therapists were rated equally highly. There was a small but significant effect of time, with later treatment sessions scoring more highly than earlier sessions. However, scores across both periods > 90%. Inter-rater reliability found a high percentage agreement of 93.3% and a Poor Kappa agreement level. Intra-rater agreement found a high percentage agreement of 97.3% and a Fair Kappa agreement level. CONCLUSIONS & IMPLICATIONS: The CommuniCATE reading therapy was implemented as per the protocol across time points, and withstood delegation to students. The high fidelity and good reliability scores have positive implications for the study's validity and reliability, and for the study's replication. WHAT THIS PAPER ADDS: What is already known on the subject TF refers to the degree to which the delivery of core components of a treatment matches the implementation guidelines, that is, the adherence to protocol. Despite the acknowledged importance of TF reporting, this is often neglected in the literature. What this paper adds to existing knowledge This paper shows that the TF assessment of the CommuniCATE study (reading strand) found a 98.2% fidelity score, and that high fidelity was not compromised across treatment conditions. This paper outlines the principles of TF and highlights the need for measures to be in place to establish TF, for example, manuals, training and supervision; and to monitor TF, for example, via the use of checklists. This paper also underlines the scarcity of TF measures and checks in aphasia research. This paper therefore serves as a model of TF practice in aphasia therapy research. What are the potential or actual clinical implications of this work? This study contributes to the findings of the CommuniCATE project (reading strand), and the high fidelity findings enhance the validity of the project and indicate that the therapy manual and training enable accurate implementation of delivery. This paper also contributes to the literature on TF evaluation in aphasia studies, which is presently lacking, and highlights the need for increased focus on the optimum strategies of TF reporting

Technology-Enhanced Reading Therapy for People With Aphasia: Findings From a Quasirandomized Waitlist Controlled Study.

Purpose This study investigated the effects of technology-enhanced reading therapy for people with reading impairments, using mainstream assistive reading technologies alongside reading strategies. Method The study used a quasirandomized waitlist controlled design. Twenty-one people with reading impairments following stroke were randomly assigned to receive 14 hr of therapy immediately or after a 6-week delay. During therapy, participants were trained to use assistive reading technology that offered a range of features to support reading comprehension. They developed skills in using the technology independently and in applying the technology to their personal reading goals. The primary outcome measure assessed reading comprehension, using Gray Oral Reading Test-Fourth Edition (GORT-4). Secondary measures were as follows: Reading Comprehension Battery for Aphasia-Second Edition, Reading Confidence and Emotions Questionnaire, Communication Activities of Daily Living-Second Edition, Visual Analog Mood Scales, and Assessment of Living With Aphasia. Matched texts were used with the GORT-4 to compare technology-assisted and unassisted reading comprehension. Mixed analyses of variance explored change between T1 and T2, when the immediate group had received therapy but the delayed group had not, thus serving as untreated controls. Pretherapy, posttherapy, and follow-up scores on the measures were also examined for all participants. Results GORT-4 results indicated that the immediately treated group improved significantly in technology-assisted reading following therapy, but not in unassisted reading. However, the data were not normally distributed, and secondary nonparametric analysis was not significant. The control group was unstable over the baseline, improving significantly in unassisted reading. The whole-group analysis showed significant gains in assisted (but not unassisted) reading after therapy that were maintained at follow-up. The Reading Confidence and Emotions Questionnaire results improved significantly following therapy, with good maintenance of change. Results on all other secondary measures were not significant. Conclusions Technology-assisted reading comprehension improved following the intervention, with treatment compensating for, rather than remediating, the reading impairment. Participants' confidence and emotions associated with reading also improved. Gains were achieved after 14 therapy sessions, using assistive technologies that are widely available and relatively affordable, meaning that this approach could be implemented in clinical practice

Enhancing communication through gesture and naming therapy

Purpose: This study investigated whether gesture, naming and strategic treatment improved the communication skills of 14 people with severe aphasia. Method: All participants received 15 hours of gesture and naming treatment (reported in a companion paper). Half the group received a further 15 hours of strategic therapy, while the remaining seven participants received no further input. The effects of therapy on communication were assessed with two novel measures. These required participants to convey simple messages and narratives to their communication partner. In both assessments a subset of the stimuli featured items that had been targets in gesture or naming treatment. Results: Performance on the communication measures was stable over two baseline assessments, but improved after gesture and naming treatment. Those who received additional strategic therapy made further gains on the message but not the narrative task. Communication gains were not specific to the stimuli featuring trained items. Conclusions: This study suggests that gesture and naming treatments can benefit interactive communication. The additional benefits of strategic therapy were less clear cut, but did impact on the transmission of simple messages. Gains seem to reflect the development of general communication skills, rather than the use of trained gestures and/or words

An Alternative Ethics? Justice and Care as Guiding Principles for Qualitative Research

The dominant conception of social research ethics is centred on deontological and consequentialist principles. In place of this, some qualitative researchers have proposed a very different approach. This appeals to a range of commitments that transform the goal of research as well as framing how it is pursued. This new ethics demands a participatory form of inquiry, one in which the relationship between researchers and researched is equalized. In this paper we examine this alternative approach, focusing in particular on two of the principles that are central to it: justice and care. We argue that there are some significant defects and dangers associated with this new conception of research ethics

Evaluating the Benefits of Aphasia Intervention Delivered in Virtual Reality: Results of a Quasi-Randomised Study

Introduction This study evaluated an intervention for people with aphasia delivered in a novel virtual reality platform called EVA Park. EVA Park contains a number of functional and fantastic locations and allows for interactive communication between multiple users. Twenty people with aphasia had 5 weeks’ intervention, during which they received daily language stimulation sessions in EVA Park from a support worker. The study employed a quasi randomised design, which compared a group that received immediate intervention with a waitlist control group. Outcome measures explored the effects of intervention on communication and language skills, communicative confidence and feelings of social isolation. Compliance with the intervention was also explored through attrition and usage data. Results There was excellent compliance with the intervention, with no participants lost to follow up and most (18/20) receiving at least 88% of the intended treatment dose. Intervention brought about significant gains on a measure of functional communication. Gains were achieved by both groups of participants, once intervention was received, and were well maintained. Changes on the measures of communicative confidence and feelings of social isolation were not achieved. Results are discussed with reference to previous aphasia therapy findings
