- The aim of this study was to investigate the writing process, using a keystroke logging program, in narratives written by patients with LGG and to compare the patients’ writing processes and products three months after tumour resection with their pre-operative performance. Twenty consecutive patients scheduled for tumour resection at Sahlgrenska University Hospital wrote to a picture-elicited narrative before and at three months follow-up using the keystroke logging program, ScriptLog (Frid, J., Johansson, V., Johansson, R., Wengelin, Å., & Johansson, M., 2014). After surgery there was a significant decline in production rate, i.e. words produced per minute. An analysis of pause distribution in different micro contexts revealed a significant increase of pauses before initiating the typing of a word. The decline in production rate suggests an increase in cognitive effort in narrative writing for patients who have undergone surgical treatment for LGG. The analysis of pause distribution indicates lexical retrieval difficulties. Investigation of the writing process can give information about subtle changes in language and cognitive processing for patients undergoing tumour resection.

- © 2018 Royal College of Speech and Language Therapists. Background: Low-grade glioma (LGG) is a type of brain tumour often situated in or near areas involved in language, sensory or motor functions. Depending on localization and tumour characteristics, language or cognitive impairments due to tumour growth and/or surgical resection are obvious risks. One task that may be at risk is writing, both because it requires intact language and memory function and because it is a very complex and cognitively demanding task. The most commonly reported language deficit in LGG patients is oral lexical-retrieval difficulties, and poor lexical retrieval would be expected to affect writing fluency. Aims: To explore whether writing fluency is affected in LGG patients before and after surgery and whether it is related to performance on tasks of oral lexical retrieval. Methods & Procedures: Twenty consecutive patients with presumed LGG wrote a narrative and performed a copy task before undergoing surgery and at 3-month follow-up using keystroke-logging software. The same tasks were performed by a reference group (N = 31). The patients were also tested using the Boston Naming Test (BNT) and word-fluency tests before and after surgery. Writing fluency was compared between the patients and the reference group, and between the patients before and after surgery. Relationships between performance on tests of oral lexical retrieval and writing fluency were investigated both before and after surgery. Outcome & Results: Different aspects of writing fluency were affected in the LGG patients both before and after surgery. However, when controlling for the effect of typing speed, the LGG group differed significantly from the reference group only in the proportion of pauses within words. After surgery, a significant decline was seen in production rate and typing speed in the narrative task, and a significant increase was seen in pauses before words. Strong positive relationships were found between oral lexical retrieval and writing fluency both before and after surgery. Conclusions & Implications: Although aspects of writing fluency were affected both before and after surgery, the results indicate that typing speed is an important factor behind the pre-surgery differences. However, the decline in overall productivity and the increase in pauses before words after surgery could be related to a lexical deficit. This is supported by the finding that oral lexical-retrieval scores were strongly correlated with writing fluency. However, further exploration is needed to identify the language and cognitive abilities affecting writing processes in LGG patients.

Konferensbidrag (refereegranskat)abstract
- Background: Early research in aphasiology seemed to view writing as written speech, implying that the symptoms would be the same in written and spoken output. However, different patterns for how difficulties are manifested in written versus spoken language have since been observed. The impressions from untrained readers add an important perspective to clinicians in how patients are able to participate in everyday life outside the clinical setting. Aim: The aim of the present study was to explore how a personal narrative told by a group of persons with aphasia differed between written and spoken language, and to compare this with findings from narratives told by participants in a reference group. Method: Eight participants with aphasia and ten participants with no neurological disorder were asked to take part in the project. The participants produced a free narration entitled ‘I have never been so afraid’, first in a written version and then also in a spoken version. The stories were analysed through holistic assessments made by 60 participants without earlier experience of aphasia and through measurement of lexical and syntactic variables. Results: The untrained readers and listeners rated the stories told by the referencegroup higher than the stories told by the participants with aphasia. The written stories made by the persons with aphasia were however rated as easier to understand, more interesting and more coherent than their spoken versions. Regression analysis revealed that the length of the stories (number of words) and word-level errors were to some extent predicting factors of the ratings, but interestingly enough not necessarily in the sense that longer and more correctly spelled stories were always rated higher. Discussion: The results showed that the impression of a written text is probably due to a very complicated network of variables. For persons suffering from aphasia it is important that they are offered language rehabilitation that includes written language. However, results also indicates that the goals for writing training have to be set individually and that more factors except spelling has to be considered when planning therapy.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Background: Persons with post-stroke aphasia have reported improvement in writing ability many years after onset of illness (Kjellén, Laakso and Henriksson, 2017). Even though studies have shown an improvement of writing ability years post stroke (most often by using dictation tasks), no longitudinal studies have continuously investigated writing ability in text production. The aim of the study was to investigate writing ability over a two year period for a person with post-stroke aphasia. Method: A 63 year old right handed man with 25 years of formal education, suffered a left hemisphere cerebri media insult. He was diagnosed with Broca’s aphasia, apraxia of speech and experienced a considerable writing impairment. The participant enrolled in the study 8 months post stroke. He had mild chronic aphasia with pertaining writing difficulties. Over a two year period he was tested three times using dictation tasks, testing both spelling of real words and non-words and a reading task. He also wrote two narratives, one picture-elicited and one free narrative. The narrative texts were collected by means of keystroke logging, which enables analysis of the writing process as well as the final text. Results: Whereas results from dictation of real words showed the greatest improvement during the first year, results from non-word dictation and the reading test showed continued improvement. Analysis of the writing process gives evidence of clear improvement in all aspects of the writing process throughout the two year period. Most strikingly, the production rate (measured as number of written words per minute) were 4,5 times faster in the free narrative between the first and the last data collection. Conclusion: Results revealed that after an improvement of spelling to dictation plateaued, measures from the writing process showed an ongoing improvement of writing ability in text production. The results further emphasize the importance of investigating text production when measuring writing ability for persons with aphasia.
