Association of serum vitamin D levels with clinical severity and recovery duration in cervical dizziness.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as an observational study.

Vitamin D deficiency has been linked to musculoskeletal pain, muscle dysfunction, and impaired postural stability; however, its role in CD remains unclear.

Who Took Part

According to the abstract, 210 patients were involved.

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

This prospective observational study included 210 patients diagnosed with CD.

Serum 25-hydroxyvitamin D [25(OH)D] levels were measured at baseline, and participants were categorized into deficiency (< 20 ng/mL), insufficiency (20-29 ng/mL), and sufficiency (≥ 30 ng/mL) groups.

How the Study Was Run

All patients received a standardized multimodal cervical rehabilitation program, with vitamin D supplementation provided to the deficient and insufficient groups.

Clinical outcomes were assessed using the Neck Disability Index (NDI), Dizziness Handicap Inventory (DHI), and Vertigo Dizziness Imbalance questionnaires (VDI-SS and VDI-QOL).

Associations between vitamin D levels, baseline symptom severity, and recovery duration were analyzed using correlation, multivariable regression, receiver operating characteristic (ROC) analysis, and partial least squares discriminant analysis (PLS-DA).

What Was Measured

The subject headings attached to it are Vitamin D, Vitamin D Deficiency, Cervical Dizziness, Recovery of Function, Disability Evaluation and Biomarkers.

Author keywords: Musculoskeletal disorders, Neck pain, Postural stability and Proprioception.
