From: The objective assessment of cough frequency: accuracy of the LR102 device
Screen shot of the off line analysis program that allows automated measurement of the cough episodes. The LR102 is based on the combined analysis of EMG signals from intercostal muscles and auditory signals. A cough episode is identified when two events occur simultaneously: 1) there is a contraction (EMG burst) of the intercostals muscles, and 2) There is a sound of predetermined intensity. Thresholds for the intensities of the EMG and audio signals can be configured.
