Aim:
To re-validate the accuracy of the Volume-Viscosity Swallow Test (V-VST) for Clinical Assessment by using a new thickening agent with an exclusive formula (ThickenUp® Clear) on 120 patients with oropharyngeal dysphagia associated with age and neurological pathology.
Results:
The study showed the V-VST using ThickenUp® Clear has high sensitivity in detecting patients with swallowing difficulty
- Sensitivity of 0.94 and specificity of 0.88 in detecting oropharyngeal dysphagia
- Sensitivity of 0.79 and specificity of 0.75 in detecting impaired efficacy
- Sensitivity of 0.87 and specificity of 0.81 in detecting impaired safety
- Sensitivity of 0.91 and specificity of 0.28 in detecting aspirations

Conclusion
The V-VST is a validated method of Clinical Assessment of dysphagia, a sequence of 3 sizes of bolus of 3 different viscosities thickened with ThickenUp® Clear, is reliable in detecting and guiding management of patients with oropharyngeal dysphagia.
