OCS
Read full descriptionHide full description
OCS-Plus provides health professionals with a brief cognitive assessment focussed on memory and executive attention. OCS-Plus was developed by the Translational Neuropsychology Research Group at the University of Oxford. The tool has been standardised, normed and validated (Demeyere et al 2021). The tool is currently undergoing further research for validity of use in specific clinical groups. The tool is not for self-assessment. Instead, a health professional assessor administers the screen to respondents to investigate domain-general cognitive impairments, with a specific focus on memory and executive attention. The tool contains multiple easy to administer tests and instructions are provided for each test. Normative data is provided for three age groups : under 60, between 60 and 70, and older than 70 and respondent performance is automatically compared to established normative cut offs. In order to activate the app for use, registration is required. There is no cost for the standard app version where data is not uploaded. Where data upload is required, an administration fee, as well as a collaboration agreement and datasharing agreement is required to be put in place.

Integrated Feedback - Complete reading tests and see your own progress. iReadMore Research Summary: - iReadMore therapy has been tested in two clinical trials. It was shown to improve reading ability in people with pure alexia (Woodhead et al., 2013) and central alexia (Woodhead et al., 2018) - In the clinical trial of iReadMore for central alexia (the most common form of acquired reading disorder), the average improvement in reading accuracy was 8.7% for trained words. Three months after finishing the therapy, users still had significantly better reading ability than before they started. - Anonymised results from the app will be collected to test how effective the app is and to improve our understanding of reading rehabilitation.
