Abstract
Introduction: There is still no standard approach to applying the Romberg test in clinical neurology and the criteria for and interpretation of an abnormal result continue to be debated.
Methods: Detailed clinical examination of 50 consecutive patients of cervical myelopathy was performed prospectively. For the walking Romberg sign, patients were asked to walk five metres with their eyes open. This was repeated with their eyes closed. Swaying or inability to complete the walk with eyes closed was interpreted as a positive walking Romberg sign. This test was compared to common clinical signs to evaluate its relevance.
Results: Whilst the Hoffman’s reflex (79%) was the most prevalent sign, the walking Romberg sign was present in 74.5% of the cases. The proprioceptive deficit was evident by only using the walking Romberg in 21 out of 38 patients that had a positive Romberg sign. Though not statistically significant, the mean 30 metre walking times were slower in patients with standing Romberg test than in those with positive walking Romberg test and fastest in those with neither of these tests positive. The combination of either Hoffman’s reflex and/or Walking Romberg was positive in 96% of patients.
Conclusion: The walking Romberg sign is more useful than the standing Romberg test as it shows evidence of a proprioceptive gait deficit in significantly more patients with cervical myelopathy than is found on conventional neurological examination. The combination of Hoffman’s reflex and walking Romberg sign has a potential as useful screening tests to detect clinically significant cervical myelopathy.
