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

Description

Yaser Said Cetin and Semra Agirbas ran a 2026 study linking vitamin D levels to the severity of cervical dizziness, a balance disorder tied to faulty posture signals from the neck. They recruited 210 patients, checked blood vitamin D at entry, and sorted patients into deficient, insufficient, and sufficient groups. All got the same multimodal neck rehabilitation programme, with supplements for those low in the vitamin, while disability and dizziness questionnaires tracked symptoms and recovery time.

Patients with lower vitamin D showed clearly worse neck disability, dizziness handicap, and quality-of-life scores at the start. Vitamin D level also tracked recovery length strongly: the lower the level, the longer recovery took. A threshold near 17 nanograms per millilitre marked slower recoveries with high accuracy in early analysis. The authors suggest checking vitamin D when judging how severe cases are and planning rehabilitation for these patients.
