The effect of vitamin D replacement on spinal inhibitory pathways in women with chronic widespread pain.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc in the context of chronic pain: fibromyalgia & crps, published as a clinical trial.

Cutaneous silent period (CSP) is the electrophysiologic analog of the spinal inhibitory pathways and an objective method to document their involvement.

Why It Was Studied

But the current literature lack studies that investigate its mechanism.

This study aims to show if vitamin D replacement has an effect on the spinal inhibitory pathways through CSP parameters.

Who Took Part

According to the abstract, 51 patients were involved.

PubMed indexes the participants as teenagers, young adults, adults, middle-aged adults and older adults, women only.

Female patients who have CWP with vitamin D deficiency were included.

Patients' pain were evaluated using the visual analog scale (VAS) and Leeds assessment of neuropathic symptoms and signs pain scale (LANSS).

How the Study Was Run

A total of 51 patients were included in the final analyses.

What Was Measured

The subject headings attached to it are Central Nervous System Sensitization, Chronic Pain, Hormone Replacement Therapy, Inhibitory Postsynaptic Potentials, Neural Pathways, Neuralgia and Pain Management.

Author keywords: Central sensitization, Chronic widespread pain, Cutaneous silent period and Vitamin D.
