Tablet-Assisted Speech and Language Therapy for Acute Post-Stroke Aphasia: A Randomized Clinical Trial (LEXI Study).

Area of Science:

• Neurology
• Rehabilitation Medicine
• Digital Health

Background:

• Aphasia following acute stroke significantly impacts communication and quality of life.
• Investigating novel therapeutic approaches is crucial for improving patient outcomes.
• Tablet-assisted interventions offer a potential avenue for enhanced rehabilitation.

Purpose of the Study:

• To compare the efficacy of tablet-assisted Speech and Language Therapy (SLT) using the Neolexon application against standard SLT for acute stroke patients.
• To evaluate the impact of digital SLT on communication recovery and patient engagement.

Main Methods:

• A prospective, open-label, randomized controlled trial involving 104 acute post-stroke aphasia patients in Germany.
• Participants received either tablet-assisted SLT or standard SLT (30 min/day) during inpatient and rehabilitation phases.
• The primary outcome was the change in Bielefelder Aphasia Screening (BIAS) percentile rank at 90 days.

Main Results:

• No significant overall difference in BIAS change was observed between the groups at 90 days; the trial was stopped early for futility.
• Patients in the tablet-assisted SLT group engaged in more frequent and longer self-directed training.
• Subgroup analyses indicated potential benefits for patients with mild to moderate aphasia and lower NIH Stroke Scale scores.

Conclusions:

• Tablet-assisted SLT, while not superior overall, shows promise for specific patient subgroups in the acute stroke phase.
• Further research may be warranted to optimize digital interventions for targeted patient populations.
• The findings highlight the need for personalized approaches in post-stroke aphasia rehabilitation.
