Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In the present study, investigators test the hypothesis that a controlled mechanical pressure applied on specific sites of both fore-feet (ES) can reduce the inflammatory state and arterial blood pressure in patients with Parkinson's Disease by increasing the overall parasympathetic activity and reducing vascular sympathetic modulation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Neuroinflammation may contribute to the cascade of events leading to neuronal loss in Parkinson's disease (PD) thus facilitating motor and autonomic impairment. A link between autonomic function and chronic and acute inflammation has been previously described. Specifically, active inflammatory state was associated with an overall increased sympathetic tone, whereas the parasympathetic cholinergic activation seemed to promote a decrease of inflammatory compounds in inflamed tissues. In addition, a functional link between peripheral sensory afferents and autonomic control has been reported. In a recent study it was observed that in PD patients a somatosensory activation by mechanical stimulation of specific sites of the fore-foot (effective stimulus, ES), improved gait, increased cardiac vagal modulation and decreased vascular sympathetic activity at rest. This latter effect was associated with a decline in arterial blood pressure values.

The present study is aimed at:

* Addressing the magnitude of the inflammatory state in PD patients.
* Testing the hypothesis that a change in the autonomic profile of PD patients induced by ES, consistent with cardiovascular increased parasympathetic and decreased sympathetic activities, may promote an overall reduction of the PD inflammatory state.

Study Groups

Foot Mechanical Stimulation

Intervention: Foot Mechanical Stimulation (FMS) will be performed on enrolled patients every 72 hours (total 5 stimulation sessions) by a pressure-controlled mechanical stimulator (Gondola®, European Community (CE) marking n° 0476) .

The sites of the stimulation will be the tip of the hallux and the lower big toe first metatarsal joint plantar surface. The FMS procedure consists in the application of the patient's calibrated pressure for 6 seconds, over the selected sites. Each of the 2 cutaneous sites of both feet will be mechanically stimulated. The procedure will be automatically repeated for 4 times in every subject so that the overall time of stimulation will be approximately 2 minutes.
