Objective measurement of cough in otherwise healthy volunteers with acute cough

This study examined objective and subjective measures of cough over two 24-hour periods in 54 otherwise healthy volunteers with acute cough (duration of <3 weeks). Subjective measures of cough included visual analog scales for cough frequency (0 [no cough] to 100 [worst cough]), cough severity (0 [no cough] to 100 [severe cough]) and difficulty falling asleep because of cough (0 [not at all] to 100 [couldn’t sleep]). Objective cough frequency was assessed using the Vitalograph VitaloJAK cough monitor.
