Non-invasive brain stimulation in amyotrophic lateral sclerosis: a systematic review and meta-analysis of transcranial direct current stimulation and transcranial magnetic stimulation.
BACKGROUND Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with limited disease-modifying treatments. Noninvasive brain stimulation techniques have been investigated as potential neuromodulatory interventions targeting cortical hyperexcitability in ALS. OBJECTIVE To systematically eval...
