The purpose of this study is the development and validation of an evidence-based mobile application, based on the core premises of Intensive Language-Action Therapy (ILAT) for aphasia, for the training and improvement of chronic aphasia patients administered at the patient's home. It aims at testing the beneficial effect on the linguistic performance (as assessed by the Barcelona and CAL clinical tests) counteracting learned non-use and the usability of the application as a tool for training once discharged from hospital care.
Acquired brain lesions such as stroke often result in the most common disabling neurological damages. Up to 42% of stroke patients suffer serious language deficits and patients are frequently left with chronic disabilities which adversely impact their quality of life. One of the main challenges in aphasia rehabilitation includes long-term effects. After a certain time (i.e., 3-6mo, chronic phase), the frequency of therapy will decrease or stop, even if the patient has not always reached the expected or desired level of recovery. After this, a body of evidence suggests that the person with aphasia might decrease the use of verbal language given the negative reinforcement when trying to use the deteriorated function and failing to achieve a successful communication. This might lead to relying on other forms of communication (e.g., gestures) and to a vicious cycle of deterioration of verbal skills known as Learned Non-Use principle. Together with the pandemic socioeconomic situation and limited resources at healthcare facilities, this calls for the need of effective and efficient interventions that can be deployed at the house of the patients, in the form of auto-administered therapy. Despite the limited exploration of portable technologies in aphasia recovery, their use has been extensive and successful in other domains such as motor rehabilitation. Importantly, patients with aphasia report that the number 1 topic they would like to know more about is how to keep recovering after therapy ends.
Following recent evidence on experience-dependent plasticity mechanisms for successful stroke recovery and well-established theory-grounded interventions, such as ILAT, the present study aims to study the usability and improvement potential of a mobile-based aphasia rehabilitation app for stroke patients, used at home. A previous collaboration between both centers (SPECS lab and Hospital Joan XIII) used a computer-based setup. In this study by Grechuta et al. (2019), the Rehabilitation Gaming System for aphasia (RGSa) shows positive significant results on language (P= 0.001) and communication (P<0.05) compared to conventional therapy in the long term (16 weeks). This study will assess the usability, risks, and clinical outcome of the same principles applied to a mobile application that is prescribed to be used at home for two twenty-minutes session per day during two weeks.

| Mobile evidence-based aphasia therapy | Behavioral | Use of mobile application to practice language for 2 weeks with a recommendation of 2 sessions per day of 20 minutes. The Android application, which is a Unity-based 2D game, will be installed on the patient's own phone, and they will play individually with the support of a family member if needed. The patients are free to start and stop using the application at any time. The application is safe to use, and it consists of therapeutic training methods such as object-matching, word search, writing, and manual voice recordings. |

| Within-group changes of language function | Clinical scale for language (Barcelona Test) will be assessed at baseline T0 (prior to the use of the application) and T1 (after two weeks of use) for the experimental group. Scale from 0 (minimum) to 365 (maximum) where higher scores indicate a better outcome. | This will be assessed one day before starting the treatment and at the end of the treatment protocol (after two weeks) |
| Within-group changes of communication | Clinical scale for communication (Communicative Activity Log; Pulvermüller et al., 2001b) will be assessed at baseline T0 (prior to the use of the application) and T1 (after two weeks of use) for the experimental group.

Participants are assigned to either an experimental group or a control group. In the experimental group the participants will receive mobile-based aphasia therapy for two weeks. In the control group participants will receive no additional therapy apart from the conventional aphasia therapy that they are already receiving.
