poly-amide is a thermoplastic material recently introduced to be used as a complete denture material, that provide excellent aesthetics and flexibility.

poly-methyl methacrylate has been commonly used as a material for constructing complete dentures and proved to have high success rate and considered to be gold standard.

Anodal DC stimulation (2 mA, 20 min) will be delivered by a constant direct current electrical stimulator connected to a pair of electrodes: the anode will be placed on the thoracic spinal cord (over the spinal process of the tenth thoracic vertebra) and the cathode (reference) above the right shoulder. Stimulating electrodes will be thick (6 mm), rectangular pieces of saline-soaked synthetic sponge. The sDCS polarity (anodal) will refer to the electrode over the spinal cord.

For sham sDCS (placebo), electrodes will be placed as for active stimulation, but the stimulator will automatically turn off after 10 s.

Spinal Direct Current Stimulation Effects on Pain in Multiple Sclerosis

Spinal Direct Current Stimulation Effects on Pain in Multiple Sclerosis: Clinical and Neurophysiological Assessment and Evaluation of Endocannabinoid System Activity

Spinal DCS (sDCS) has been proven to modulate Nociceptive Withdrawal Reflex (NWR), an objective and sensitive tool to explore pain processing at the Spinal Level and recommended by European Federation of Neurological Society (EFNS) to evaluate the analgesic effect of treatments.

The endocannabinoid system is involved in descending central pain control and can be modulated by other neurostimulation techniques as transcutaneous electrical nerve stimulation. The investigators suppose that one of the major effect of sDCS is to modulate supraspinal central pain control through activation of endocannabinoid system inducing the analgesic effect. Alteration of endocannabinoid system activity is also involved in other pathological aspects of Multiple Sclerosis as spasms, spasticity and incontinence and to acute and chronic neurodegeneration (anti-oxidant activity and inhibition of glutamate release and signalling). Activity of Fatty Acid Amide Hydrolase (FAAH) in platelets will be quantify.

As sDCS reduces NWR area and as it may modulate endocannabinoid system, the investigators could suppose other positive effects of this treatment in Multiple Sclerosis patients as reduction of painful spasms and spasticity. The investigators will evaluate the effect of sDCS on spasticity, if present, investigating its effect on validate ad hoc scales (Ashworth scale) and on neurophysiological acquisitions (H reflex).
