表面肌电图（EMG）信号检测从喉区的7个正常和7发声功能亢进的扬声器在休息，两个阻力演习，元音生产，并连接语音。元音基频，绝对和相对周期扰动，喉触诊评级，以及粗糙度评级。两组在所有EMG测量上差异显著，除了与阻力动作、元音EMG与静息EMG比率和言语EMG与静息EMG比率相关的那些。选择的临床指标和言语EMG值之间存在明显的中高相关性。
Surface electromyographic (EMG) signals were detected from the laryngeal area of 7 normal and 7 vocally hyperfunctional speakers during rest, two resisted-force maneuvers, vowel production, and connected speech. Vowel fundamental frequency, absolute and relative period perturbation, laryngeal-palpation ratings, and harshness ratings were acquired as well. The two groups differed significantly on all EMG measures except those associated with the resisted-force maneuvers, the vowel EMG-to-rest EMG ratio, and the speech EMG-to-rest EMG ratio. Moderately high correlations were evident between selected clinical measures and speech EMG values.
