Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Objective: aim of the study is to verify whether neuromuscular magnetic stimulation can improve muscle function in spinal-onset Amyotrophic Lateral Sclerosis (ALS) patients. We will study if neuromuscular magnetic stimulation can counteract muscle atrophy by promoting the modulation of factors associated with muscle catabolism and/or increasing the efficacy of nicotinic acetylcholine receptors.
Methods: At the baseline visit, ALS patients will be randomized in two groups to receive daily real neuromuscular magnetic stimulation in one arm and sham neuromuscular magnetic stimulation in the opposite arm for two weeks. All patients will undergo median nerve conduction study and a clinical examination, including handgrip strength test and evaluation of upper limbs muscle strength by Medical Research Council Muscle Scale. At the end of the stimulation procedures, a needle muscle biopsy will be performed bilaterally from flexor carpi radialis muscle. Muscle samples will be used to perform histomorphometric and molecular analysis and electrophysiological recordings of acetylcholine evoked currents.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Right-real NMMS Group
It will receive a real stimulation (rNMMS) of the right arm and a sham stimulation (sNMMS) of the left arm
Neuromuscular magnetic stimulation (NMMS)
It is a non-invasive, stimulation technique that does not induce high-intensity cutaneous electric fields and does not activate skin nociceptors, thus resulting in a painless and better-tolerated procedure. rNMMS is delivered through a high-frequency magnetic stimulator connected to a conventional circular cooled coil. Magnetic stimulator is placed above the flexor muscles of the forearm. rNMMS is delivered at a 5-Hz frequency and with a 100% stimulation intensity of 100% of the maximum intensity in 140 trains of 50 stimuli. sNMMS is delivered with a sham coil producing similar acoustic sensations and mechanical skin perceptions.
Left-real NMMS Group
It will receive a rNMMS of the left arm and a sNMMS of the right arm
