Neurophysiologic Study on Effects of Sativex® on Spasticity in Progressive Multiple Sclerosis

Aim of this randomized, double-blind, placebo-controlled, cross-over study is to investigate cannabinoid-induced changes in neurophysiological parameters in a group of 40 patients with secondary or primary progressive Multiple Sclerosis (MS).

primary outcomes

primary measures

H/M reflex ratio

Time frame: week 0, 4

To evaluate differences in the H/M ratio scores within subjects affected by progressive MS at baseline and week 4.

secondary outcomes

secondary 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

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);
