OBJECTIVES To test a new neurological sign, the "abductor sign," which can distinguish between organic and non-organic leg paresis using synergic movements of the bilateral hip abductors. METHODS The subjects were 33 patients presenting with paresis of one leg, 17 of organic origin and 16 of non-organic origin (hysteria). To test the abductor sign, the examiner told the patient to abduct each...

OBJECTIVES/HYPOTHESIS The diagnosis of paresis in patients with vocal fold motion impairment remains a challenge. More than 27 clinical parameters have been cited that may signify paresis. We hypothesize that some features are more significant than others. STUDY DESIGN Prospective case series. METHODS Two laryngologists rated laryngoscopy findings in 19 patients suspected of paresis. The di...

OBJECTIVES The purpose of this study was to determine whether the videostroboscopic finding of vibratory asymmetry in mobile vocal folds is a reliable predictor of vocal fold paresis. In addition, the ability of experienced reviewers to predict the distribution (left/right/bilateral) of the paresis was investigated. METHODS This is a retrospective chart review of all patients who presented to...

OBJECTIVES/HYPOTHESIS Vocal fold paresis and paralysis are common conditions. Treatment options include augmentation laryngoplasty and voice therapy. The optimal management for this condition is unclear. The objective of this study was to assess possible neuromuscular compensation mechanisms that could potentially be used in the treatment of vocal fold paresis and paralysis. STUDY DESIGN In v...

Dr. Nelson has no financial or proprietary interest in the materials presented herein. doi: 10.3928/01913913-20121008-01 Acute fourth nerve paresis is probably the most frequent cause of acquired vertical diplopia. In this issue, Khaier et al. found that many cases of acute fourth nerve paresis have a benign etiology and clinical course. Although the most common cause of vertical diplopia relat...

BACKGROUND The existence of a prenuclear abduction paresis is still debated. METHODS In a retrospective design, we identified 22 patients with isolated unilateral (n = 20) or bilateral (n = 2) abduction paresis and electrophysiologic abnormalities indicating rostral pontine and/or mesencephalic lesions. Another 11 patients had unilateral abduction paresis with additional ocular motor abnormal...
