About

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: 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. 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.

36 participants in 2 patient groups

Experimental Group
Experimental group
Description:
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.
Treatment:
Other: PCT
Control Group 1 [Conventional Workbook Therapy]
Active Comparator group
Description:
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.
