Laryngeal electromyography can provide prognostic information when evaluating patients with vocal cord dysfunction. Twenty-four patients were studied to determine the predictive capacity of this test. Six patients had bilateral vocal cord paralysis, constituting a total of 30 vocal cords examined. Sixteen of these cords had decreased or absent motor unit potentials, fibrillations, or positive waves. None of these patients recovered function. Fourteen cords demonstrated either normal motor unit or polyphasic potentials. Return of mobility was evident in 11 of these cords. The combined total was 27 of 30 cords correctly predicted, demonstrating a 90% accuracy rate.
在评估声带功能障碍患者时，喉肌电图可提供预后信息。对24例患者进行研究以确定该检查的预测能力。6例患者出现双侧声带麻痹，共检查了30条声带。其中16条声带运动单位电位降低或缺失、出现纤颤或正波。这些患者均未恢复功能。14条声带显示运动单位电位正常或呈多相波。其中11条声带恢复了活动能力。30条声带中共有27条预测正确，准确率达90%。
