Due to the high percentage of musicians who suffer from musculoskeletal disorders, there is a need for more research in the field of music and medicine. The purpose of this study was to analyze the possible relationship between anxiety, muscle activation, and muscle fatigue in undergraduate trumpet players. Assessment tools included surface electromyography (sEMG) data, State Trait Anxiety Inventory (STAI), and Visual Analogue Scales (VAS) of perceived anxiety. Data were collected from 27 undergraduate music students across five universities (22 males, 5 females) aged 18 to 24 years. The three muscles targeted by the sEMG were the upper trapezius, sternocleidomastoid, and masseter muscles. Participants were randomly divided into two single-blinded groups: (1) anxiety-induction and (2) control. The anxiety-induction group was instructed to play as accurately as possible and informed that mistakes were being counted and evaluated, while the control group was instructed to play without any concern for possible mistakes. The anxiety-induction group was shown to have more masseter muscle activation than the control; the anxiety-induction group also displayed a higher fatigue rate in all three muscles versus the controls. Subjects with high perceived-anxiety (as measured by VAS) displayed higher masseter activation and higher fatigue rates in the upper trapezius and sternocleidomastoid than non-anxious participants. Despite these notable trends, there was no statistical significance for any of the muscle groups for muscle activation or fatigue.
由于患有肌肉骨骼疾病的音乐家比例很高，因此需要在音乐与医学领域开展更多研究。本研究的目的是分析本科小号演奏者焦虑、肌肉激活和肌肉疲劳之间的可能关系。评估工具包括表面肌电图（sEMG）数据、状态特质焦虑量表（STAI）和感知焦虑视觉模拟量表（VAS）。数据收集自五所大学的27名本科音乐专业学生（22名男性，5名女性），年龄在18至24岁之间。sEMG针对的三块肌肉是上斜方肌、胸锁乳突肌和咬肌。参与者被随机分为两个单盲组：（1）焦虑诱导组和（2）对照组。焦虑诱导组被要求尽可能准确地演奏，并被告知错误正在被计数和评估，而对照组被要求在演奏时无需担心可能出现的错误。结果显示，焦虑诱导组的咬肌激活程度高于对照组；与对照组相比，焦虑诱导组的三块肌肉疲劳率也更高。高感知焦虑受试者（通过VAS测量）的咬肌激活程度更高，上斜方肌和胸锁乳突肌的疲劳率也高于非焦虑参与者。尽管有这些明显趋势，但任何肌肉组在肌肉激活或疲劳方面均无统计学意义。
