This study aims to evaluate safety and efficacy of tSMS in ALS patients and to obtain preliminary data about the effects of tSMS on cortical excitability.
To this purpose, 40 ALS patients will be recruited and randomized to real or sham tSMS. After at least 3 months follow-up, they will undergo tSMS, daily for 120 min, at home, for 6 consecutive months.
Clinical status will be tested before, during and after the stimulation period. Moreover, cortical excitability will be tested by transcranial magnetic stimulation (TMS) before and after the stimulation period.

Experimental: real tSMS
tSMS will be delivered by a magnet applied to M1, bilaterally (120 min daily, for 6 months). Magnet will be kept in position by a plastic helmet.
tSMS delivered on bilateral motor cortex
Sham Comparator: sham tSMS
A non-magnetic steel cylinder, with same size, weight and appearance of the magnet, will be used for sham stimulation.
Device: sham tSMS

- Disease progression [ Time Frame: 9 months ]Comparison between the ALSFRS-R (Revised Amyotrophic Lateral Sclerosis Functional Rating Scale) decline over the period of at least three months before the treatment and the period of six months during the treatment. The ALSFRS-R is 12-items scale ranking from 0 (worse) to 48 (better) points.
- Safety and tolerability [ Time Frame: 6 months ]Incidence of adverse events during the stimulation period
- Compliance [ Time Frame: 6 months ]Number of stimulation sessions actually completed by each patient
- Effect on resting motor threshold (RMT) and active motor threshold (AMT) [ Time Frame: 6 months ]Change in TMS-derived cortical excitability parameters (RMT and AMT) before and after stimulation period.
- Effect on motor evoked potentials (MEP) size [ Time Frame: 6 months ]Change in TMS-derived cortical excitability parameters (MEP size) before and after stimulation period.
