Investigation of unilateral sensory or motor symptoms: frequency of neurological pathology depends on side of symptoms.

The records of 82 patients who had undergone inpatient neurological investigation for unilateral motor symptoms, sensory symptoms, or both, without definite neurological signs, were reviewed. Diagnosis of a physical disorder was more frequent if symptoms were on the right side rather than on the left (odds ratio (OR) = 7.7, 95% confidence interval (95% CI) 2.6-23), and in males than in females (OR = 3.0, 95% CI 1.1-8.3).
