- Brief Summary
Given the evolving uses of technology in rehabilitation, the investigators aimed to measure the change in aphasia severity using PCT App, a digital therapeutic adapted from Constant Therapy (CT), a dynamic, personalized therapy program for people with cognitive, speech, or language disorders.
The entire study, including recruitment, enrollment, assessment and treatment were conducted remotely.
The proposed pilot study seeks to compare performance of PCT therapy vs. conventional workbook intervention for stroke patients. The investigators hypothesize that the experimental (PCT) group will experience greater gains on the WAB-AQ at follow-up compared to baseline compared to a control (workbook) group.
Subjects were prospectively assigned to an experimental or active control group in a random order with both groups balanced for their baseline level of speech, language and/or cognitive ability:
1. Experimental Group: Participants were instructed to use PCT for at least 30 minutes/day, 5 days/week. Performance and usage data were automatically reported by the PCT software to the treating clinician and was used to modify task assignment over time and monitor participant adherence to the treatment program.
2. Active Control Group: Participants were provided with a standard regime of paper workbooks (e.g. Workbook for Aphasia; Brubaker, 2006) that are typically used by clinicians with persons with aphasia (PWA) for at least 30 minutes/day, 5 days/week. Notably, the control procedure employed here is similar to a large-scale study examining technology as a treatment option by Palmer and colleagues (2015).
The treatment period was 10 weeks. All participants received a bimonthly check-in through video-chat with a member of the research staff during the treatment period.

Group Intervention Description Experimental Group PCT At the start of the study, subjects will be provided with a tablet with videoconferencing software and the PCT app pre-installed. Research staff will remotely setup a PCT account for the subjects, and provide instructions for logging into the PCT application. During the treatment period, patients will be instructed to use PCT for at least 30 minutes a day and at least 5 days a week. Performance data (accuracy and latency) will be reported by the PCT software to the treating clinician and will be used to modify task assignment over time. PCT tracks usage of the program so that research staff can access automated reporting of subject use to monitor participant adherence to the treatment program. Control Group 1 [Conventional Workbook Therapy] Workbooks At the start of the study, subjects will be provided with a tablet with videoconferencing software and the PCT app pre-installed. Subjects in the control group will be told they will have access to 3-months of PCT after their participation in the study has concluded. Subjects in this group will be provided with a standard regime of paper workbooks and instructions to complete approximately 30 minutes a day at least 5 days a week.
- Primary Outcome Measures
Name Time Method Western Aphasia Battery Revised, Aphasia Quotient (WAB-AQ) Follow-up assessment 10-12 weeks post baseline The WAB-R is a standardized tool that assesses language and cognitive skills and provides scores quantifying the impact of a stroke on those skills. The Aphasia Quotient from the WAB-R includes segments from Part 1 of the assessment, evaluating spontaneous speech including fluency and information content, auditory comprehension, naming, and repetition.
- Secondary Outcome Measures
Name Time Method Western Aphasia Battery Revised, Language Quotient (WAB-LQ) Follow-up assessment 10-12 weeks post baseline The Language Quotient as obtained from the WAB-R Parts 1 and 2 was utilized as secondary outcome measures. Part 2 of the WAB-R informing the Language Quotients includes reading and writing sections.
Western Aphasia Battery Revised, Cortical Quotient (WAB-CQ) Follow-up assessment 10-12 weeks post baseline The Cortical Quotient as obtained from the WAB-R Parts 1 and 2 was utilized as secondary outcome measures. Part 2 of the WAB-R includes reading, writing, apraxia, constructional, visuospatial, and calculation sections.
Stroke and Aphasia Quality of Life Scale 39 (SAQOL-39) Follow-up assessment 10-12 weeks post baseline The SAQOL-39 is a structured quality of life questionnaire administered to either a patient or a caregiver. It assesses the impact of a stroke on daily activities, communication, emotions, and family and social life by asking patients or caregivers to complete a 5 point rating scale in response to specific questions focusing on the past week alone.
Brief Test of Adult Cognition by Telephone (BTACT) Follow-up assessment 10-12 weeks post baseline The BTACT is a brief, remote, cognitive assessment that evaluates memory for and judgments about words and numbers. It includes tasks such as recall tasks, both immediate and short term, category fluency, and number reasoning and manipulation tasks.
