Sažetak
Background: Electromyography (EMG) and nerve conduction studies (NCS) are an unpleasant and sometimes painful
examinations. Pain can reduce patient’s compliance and have a negative effect on the examination results. Different studies rep ort
that music affects pain perception by acting as a distractor, by inducing positive emotional valence or through the concept of
convergence of different sensory modalities. The aim of this study was to explore the effect of music and different environment al and
sociodemographic factors on pain perception during EMG and NCS.
Subjects and methods: Sixty patients with suspected neuromuscular disease were randomized into music and control group.
Specific questionnaire assessed sociodemographic characteristics, medical history, examination waiting time, examination extent
and biometeorological forecast. The numerical rating scale was used for the evaluation of pain. The examiner evaluated patient’ s
compliance after the examination.
Results: NCS was less painful for patients in the music group (p=0.03), as well as for more cooperative patients (p=0.011). For
patients who previously underwent EMG/NCS, present NCS was more painful (p=0.001), regardless of the music intervention
(p=0.019). EMG was more painful for older patients (p=0.041). Patients with lower level of education reported lower pain during
NCS (p=0.026). Gender, financial satisfaction, biometeorological forecast, diabetes, depression or malignant disease, use and
dosing of analgesics or antidepressants, symptoms, examination waiting time and the examination extent had no effect on pain
perception.
Conclusions: Music significantly decreased the perception of pain associated with NCS, but not the EMG portion of the
examination. During EMG pain level was not significantly reduced, but the median of pain was still lower. Generally, the pain l evel
during NCS, unlike the one during EMG, was affected by patients' compliance, level of education and painful predetermination. W e
propose using music during EMG/NCS because it can make the examination more comfortable for the patient and thus contribute to
better quality of this examination.
