User profiles and digital engagement patterns in app based aphasia rehabilitation in a multilingual low resource setting

Background The rapid integration of digital health interventions into neurorehabilitation has introduced new paradigms in aphasia therapy, particularly in regions with limited access to traditional clinical services. While numerous studies confirm the clinical efficacy of app-based rehabilitation tools, less is known about how individuals engage with such tools in real-world contexts, especially in multilingual, low-resource settings such as India.Aim This study investigates digital engagement profiles among 18 individuals with aphasia who utilized the Constant Therapy Hindi application on Android phones.Methods & Procedures By applying a pattern identification approach, user subgroups were identified based on literacy, technological familiarity, caregiver support, and cognitive-linguistic characteristics.Results & Conclusions The pattern identification yielded three primary user profiles that reflect diverse engagement patterns and support needs. Each group exhibited distinct engagement behaviors, including variations in cue usage and task compliance. The findings suggest that engagement with digital therapy is influenced more by external support and cognitive-linguistic factors than by educational level or ability to independently use smartphones alone. These results highlight the need for context-sensitive and flexible digital rehabilitation approaches in multilingual, low-resource settings.
