Vitamin D Supplementation in Patients with Chronic Low Back Pain: An Open Label, Single Arm Clinical Trial.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in the context of chronic pain: fibromyalgia & crps in this clinical trial publication.

The study is aimed to assess the impact of vitamin-D supplementation on pain intensity, functional disability, and vitamin-D levels in patients with CLBP.

Why It Was Studied

Vitamin-D deficiency may possibly be related to chronic low back pain (CLBP).

Who Took Part

PubMed indexes the participants as adults and middle-aged adults, both men and women.

Outpatient pain clinic of a tertiary care hospital.

Sixty-eight eligible patients (CLBP for = 3 months, pain score = 50 on visual analogue scale (VAS) and plasma 25-Hydroxyvitamin D3 levels < 30 ng/mL) were enrolled.

How the Study Was Run

In design terms this was an open-label study.

Nothing was hidden in this open-label Vitamin D, K2, Magnesium and Zinc study: the participants and staff both knew the treatment.

Plasma 25(OH) D3 levels were measured at baseline and 8 weeks.

What Was Measured

The subject headings attached to it are Calcifediol, Cholecalciferol, Dietary Supplements, Low Back Pain, Pain Management and Vitamin D Deficiency.
