Primary Outcome Measures:
  • H/M reflex ratio [ Time Frame: week 0, 4 ] [ Designated as safety issue: No ]
    To evaluate differences in the H/M ratio scores within subjects affected by progressive MS at baseline and week 4.


Secondary Outcome Measures:
  • Neurophysiology ·H/M ratio ·Transcranial Magnetic Stimulation a) MEP Motor threshold, upper limb b) MEPs amplitudes c) Intracortical facilitation/inhibition (ICI/ICF), upper limb [ Time Frame: week 0, 4, 6 and 10 ] [ Designated as safety issue: No ]

    Neurophysiology

    • H/M ratio: To evaluate differences in the H/M ratio scores within subjects affected by progressive MS at weeks 6 and 10
    • Transcranial Magnetic Stimulation

      1. Motor threshold to obtain MEPs to the upper limb (time 0-4; 6-10 weeks);
      2. MEPs amplitudes at 15% above motor threshold, measured as MEP/M ratio to APB (abductor pollicis brevis) and abductor of hallucis, in which M is the compound muscle potential in response to peripheral stimulation (time 0-4; 6-10 weeks);
      3. Intracortical facilitation/inhibition (ICI/ICF) to the upper limb (time 0-4; 6-10 weeks);

  • Adverse Events recording [ Time Frame: week 0, 4, 6 and 10 ] [ Designated as safety issue: Yes ]
  • Spasticity: ·0-10 11-point numerical spasticity rating scale (NRS) ·Mean modified Ashworth scale (MAS) [ Time Frame: week 0, 4, 6, 10 ] [ Designated as safety issue: No ]

    Mean spasticity score recorded using a 0-10 11-point numerical spasticity rating scale (NRS) at baseline (pre-treatment) and week 4, 6 and 10

    · Mean modified Ashworth (MAS) score at baseline (pre-treatment), week 4, 6, 10


  • Function: ·Timed 25 feet and 10 meters walk ·Hand dexterity measured with 9-HPT [ Time Frame: week 0, 4, 6, 10 ] [ Designated as safety issue: No ]

    Function:

    • Mean Timed 25 feet and 10 meters walk recorded at baseline (pre-treatment) and week 4, 6, 10
    • Mean Hand dexterity measured with 9-HPT recorded at baseline (pre-treatment) and week 4, 6, 10

  • Other MS Symptoms: ·Sleep Quality NRS ·Pain NRS and Spasm frequency ·Fatigue Severity Scale (FSS) [ Time Frame: week 0, 4, 6, 10 ] [ Designated as safety issue: No ]

    Other MS Symptoms:

    • Mean Sleep Quality NRS recorded at baseline (pre-treatment) and week 4, 6, 10
    • Pain NRS and Spasm frequency recorded at baseline (pre-treatment) and week 4, 6, 10
    • Fatigue measured with the Fatigue Severity Scale (FSS) recorded at baseline (pre-treatment) and week 4, 6, 10
