The vibration quantitation scale (VQS): a simple, reproducible bedside measure of sensory function in multiple sclerosis.
OBJECTIVES: To assess the utility of a bedside measure of sensation (the Vibration Quantitation Scale (VQS)) in patients with multiple sclerosis (MS) and in normal controls. To correlate the VQS with the Kurtzke Expanded Disability Severity Score (EDSS) and sensory abnormalities in these patients.
METHODS: We developed the VQS and tested its performance in patients with MS of various ages, MS types, and EDSS scores. We compared this with controls (normal volunteers or patients with other neurological diseases) who did not have sensory symptoms. In a subgroup, two examiners measured VQS independently at the same patient visit. A standard C-128 tuning fork was used for the VQS measurement.
RESULTS: The VQS had a good inter-observer reproducibility (r=0.920, p
CONCLUSIONS: The VQS provides a continuous sensory scale applicable in most patients with MS, which is measurable with standard bedside equipment, and which may avoid some of the pitfalls of sensory scoring in MS.
