Modulation of the Motor Pathway by Transcranial Pulse Stimulation in People With ALS: a Pilot Randomized Trial
The goal of this clinical trial is to assess the efficacy of TPS of the motor cortex on biomarkers and clinical endpoints in patients with ALS. The main questions it aims to answer are: * Stage 1: Is there a change in the short intracortical inhibition (SICI) of the motor cortex from baseline to week 8? * Stage 2: Is there a change from baseline to month 6 in the ALS functional rating scale-revised (ALSFRS-R) total score? In stage 2, researchers will compare the group receiving the stimulation vs the group receiving a sham stimulation to see if there is a difference in motor cortex activity and in the ALSFRS-R score Participants will receive either: * the TPS treatment * a sham TPS treatment
• Patients with diagnosis of sporadic ALS (definite or clinically probable) as defined by the World Federation of Neurology revised El Escorial criteria
• SVC of 50% or greater of estimated measure and presence of measurable motor evoked potential
• 21 to 80 years old and male or female
