Musculoskeletal Pain as a Risk Factor for Poor Dizziness Outcomes: A Longitudinal Study Among Patients With...

Area of Science:

• Neurology
• Psychology
• Pain Management

Background:

• Persistent dizziness is often accompanied by musculoskeletal pain and psychological distress.
• The influence of comorbid pain on dizziness outcomes remains poorly understood.

Purpose of the Study:

• To investigate the impact of musculoskeletal pain on the outcomes of persistent dizziness.
• To explore the potential modifying role of psychological distress in this relationship.

Main Methods:

• A longitudinal study involving 150 patients with persistent dizziness.
• Assessment of dizziness symptoms (Vertigo Symptom Scale - short form, Dizziness Handicap Inventory), pain (number of sites, intensity), and psychological distress (Hospital Anxiety and Depression Scale) at baseline, 6, and 12 months.
• Statistical analysis using linear mixed effects models and interaction analysis to determine the association between pain and dizziness and the effect of psychological distress.

Main Results:

• Patients with psychological distress reported higher dizziness scores, more pain sites, and greater pain intensity.
• A significant positive association was found between the number of pain sites/intensity and dizziness severity, which was amplified by psychological distress.
• Baseline pain (≥4 sites or intensity ≥4/10) predicted severe dizziness and moderate disability at 12 months.

Conclusions:

• Musculoskeletal pain is a significant risk factor for poor outcomes in persistent dizziness, especially when psychological distress is present.
• Clinicians should consider musculoskeletal pain, particularly with multiple pain sites or high intensity, as a critical factor in dizziness management.
• Addressing comorbid pain and psychological distress is essential for improving recovery and preventing long-term dizziness issues.
