Abstract

Objective: To investigate the effects of music on pain and vital signs during electromyographic examination(EMG)- electrodiagnosis. Method: Before the EMG-electrodiagnosis, we measured blood pressure, pulse rate, and respiration rate of 60 subjects. During the EMG-electrodiagnosis, peaceful and slow-rhythm music was delivered to 30 subjects in music group and a sham music to 30 subjects in control group. After EMG-electrodiagnosis, intensity of pain was assessed by Visual Analogue Scale (VAS) and Pain Rating Index (PRI) of McGill Pain Questionaire and blood pressure, pulse rate, and respiration rate were checked. Results: The VAS score and PRI were significantly lower in music group than control group (p<0.05). The respiration rate was also significantly lower in music group (p<0.05). Conclusion: The application of music during EMG-electrodiagnosis decreases the intensity of pain and change of vital signs.
