RecruitingClinical trialA Randomized Controlled Trial to Assess the Impact of Live and Recorded Music-Based Interventions on Pre-operative Stress, Mood, Pain and Biomarkers, in Neurosurgical Patients (Music-STAR Trial)The study plans to enroll a total of 132 patients. The goal of this study is to measure pre-and post-music intervention changes in patients' vital signs, serum- and plasma-level biomarkers by broad-spectrum proteomics analysis, metabolic analysis, and perceived pain, anxiety, and mood states as measured by validated questionnaires (STAI-S, POMS-SF, and VASP). We will collect demographic information on each participant. Participants will also complete the Brief Musical Experience Questionnaire (BMEQ) to investigate potential links between susceptibility to music-induced anxiolysis and prior musical training, preference and exposure.
