Cerebellar Brain Stimulation Plus Language Therapy for People at Risk of Poor Aphasia Recovery After Stroke
Sponsor: Johns Hopkins University
Summary
This pilot study tests whether a mild form of brain stimulation to the cerebellum, combined with computer-based language therapy, helps people recover language after a stroke when a poor natural recovery is predicted. People already taking part in a Johns Hopkins study of stroke and language recovery, whose early data suggest the aphasia is unlikely to resolve without treatment, are invited about 3 months after the stroke. Half begin 15 treatment sessions right away and half begin about 3 months later. Each session pairs 25 minutes of transcranial direct current stimulation (tDCS) over the right cerebellum with 45 to 60 minutes of language exercises, with a speech-language pathologist present. The main question is whether language ability, measured with the Western Aphasia Battery-Revised Aphasia Quotient, improves more by 6 months after stroke in the group treated first than in the group still waiting. The study also checks how accurately a machine learning model, built from data collected in the first days after stroke, predicted each person's language ability 12 months after stroke.

Interventions
Cathodal cerebellar transcranial direct current stimulation
Cathode (saline-soaked sponge electrode) over the right cerebellum, 1 cm below the inion and 4 cm lateral; anode over the right deltoid. Constant current of 2 mA for 25 minutes, ramped up over the first 15 seconds, from a battery-powered Soterix Medical 1x1 stimulator with pre-programmed parameters. Delivered during the first 25 minutes of each language therapy session.
Computerized language therapy
Computer-delivered language exercises on a tablet, targeting spoken and written picture naming, auditory comprehension, reading and spelling, 45 to 60 minutes per session, with difficulty adjusted to performance and a speech-language pathologist present. Each participant uses the same delivery platform for all sessions.
