Abstract
This study investigated the effect of acupuncture on emotional stress in subjects with phonotraumatic injuries. This study used a prospective randomized, placebo-controlled group design. The independent variable included the types of acupuncture (genuine vs sham) and the sampling time points (two pre-needling, one in the midway of needling, and two post-needling measurements). The dependent variable was the concentration of cortisol obtained from subjects' saliva samples. Eighteen female subjects with phonotraumatic injuries were randomized to receive either genuine or sham acupuncture at the same acupoints during a 30-minute session. Saliva samples were collected from each subject at 10 minutes pre-needling, immediately pre-needling, mid-needling, immediately postneedling, and 10 minutes post-needling time points. The findings suggested that the subjects' salivary cortisol concentration did not reduce after acupuncture, and thus, acupuncture may not be able to reduce the emotional stress level in female dysphonic speakers.
