The intrinsic laryngeal muscle potential was recorded with electromyography. Vocal cord movements were observed by a video stroboscope. Laryngeal paralysis is divided into mild, moderate, and severe degrees based on the potentials of intrinsic laryngeal muscles and on the status of vocal cord movements. In the past 11 years (from 1983 to 1993) 1211 cases were diagnosed as having mild, moderate, and severe laryngeal paralysis. Among them, there were 11 cases with laryngospasm including 3 mild, 2 moderate, and 6 severe cases. The findings obtained from careful observation on these 11 cases of laryngospasm demonstrated that there were certain relationships between laryngeal paralysis and laryngospasm. During the course of exacerbation or restoration of paralysis, the laryngospasm may occur.
采用肌电图记录喉内肌电位。通过频闪喉镜观察声带运动。根据喉内肌电位和声带运动状态，将喉麻痹分为轻、中、重三度。在过去11年（1983年至1993年）中，1211例被诊断为患有轻、中、重度喉麻痹。其中，有11例喉痉挛患者，包括3例轻度、2例中度和6例重度。对这11例喉痉挛患者进行仔细观察的结果表明，喉麻痹与喉痉挛之间存在一定关系。在麻痹加重或恢复过程中，可能会发生喉痉挛。
