HD-tDCS in Amyotrophic Lateral Sclerosis: A Multicenter Randomized Controlled Trial

High-Definition Transcranial Direct Current Stimulation (HD-tDCS) in Amyotrophic Lateral Sclerosis: A Multicenter Randomized Controlled Trial

Source: ClinicalTrials.gov · Last updated 20 Jul 2026

Brief summary (registry, in English)

Amyotrophic Lateral Sclerosis (ALS) is a nervous system disease that causes muscle weakness and rapidly progresses to the loss of mobility and functionality. Studies suggest that High-Definition Transcranial Direct Current Stimulation (HD-tDCS) is a technique for modulating motor cortical hyperexcitability. However, evidence on the use of HD-tDCS as a neuromodulator of the diaphragmatic motor cortex in people with ALS is inconclusive.
