Prevalence, etiology, and biopsychosocial risk factors of cervicogenic dizziness in patients with neck pain: A multi-center, cross-sectional study.

OBJECTIVES: This study aims to investigate the prevalence, etiology, and risk factors of cervicogenic dizziness in patients with neck pain. PATIENTS AND METHODS: Between June 2016 and April 2018, a total of 2,361 patients (526 males, 1,835 females; mean age: 45.0±13.3 years; range, 18 to 75 years) who presented with the complaint of neck pain lasting for at least one month were included in this prospective, cross-sectional study. Data including concomitant dizziness, severity, and quality of life (QoL) impact of vertigo (via Numeric Dizziness Scale [NDS]), QoL (via Dizziness Handicap Inventory [DHI]), mobility (via Timed Up-and-Go [TUG] test), balance performance [via Berg Balance Scale [BBS]), and emotional status (via Hospital Anxiety- Depression Scale [HADS]) were recorded. RESULTS: Dizziness was evident in 40.1% of the patients. Myofascial pain syndrome (MPS) was the most common etiology for neck pain (58.5%) and accompanied with cervicogenic dizziness in 59.7% of the patients. Female versus male sex (odds ratio [OR]: 1.641, 95% CI: 1.241 to 2.171, p=0.001), housewifery versus other occupations (OR: 1.285, 95% CI: 1.006 to 1.642, p=0.045), and lower versus higher education (OR: 1.649-2.564, p<0.001) significantly predicted the increased risk of dizziness in neck pain patients. Patient with dizziness due to MPS had lower dizziness severity scores (p=0.034) and milder impact of dizziness on QoL (p=0.005), lower DHI scores (p=0.004), shorter time to complete the TUG test (p=0.001) and higher BBS scores (p=0.001). CONCLUSION: Our findings suggest a significant impact of biopsychosocial factors on the likelihood and severity of dizziness and association of dizziness due to MPS with better clinical status.

Is physical rehabilitation effective for Wernicke-Korsakoff syndrome? A case report.

Wernicke-Korsakoff syndrome is a type of brain disorder caused by the lack of thiamine, most commonly because of chronic alcohol misuse. It consists of two separate conditions including Wernicke's encephalopathy and Korsakoff syndrome. Various levels of cognitive impairments are associated with the severity of the syndrome. Although the effectiveness of thiamine replacement in the early phases of the syndrome is proven, the efficacy of subsequent treatments, which mainly include rehabilitation protocols after the development of Korsakoff syndrome, is not clear. This is the first report showing the positive effects of physical rehabilitation in a 48-year-old male patient with Wernicke-Korsakoff syndrome.
