The aims of this study were to explore muscle activity levels during different violin repertoires, quantify the general levels bilaterally in upper extremity muscles, and evaluate associations between muscle activity and anthropometrics characteristics. In 18 skilled violin players surface EMG was recorded bilaterally from trapezius (UT), flexor digitorum superficialis (FDS), extensor carpi ulnaris (ECU), extensor digitorum cummunis (EDC), and extensor carpi radialis (ECR) during A and E major scales played in three octaves and Mozart’s Violin Concerto no. 5. To compare side differences the static, median and peak levels of muscle activity were calculated from an amplitude probability distribution function (APDF). This study demonstrated that scales played as standardized tasks can be used to estimate the average muscle activity during violin playing. Comparing results from scales and the music piece revealed a similar muscle activity across all muscles in the music piece and E major scales. The static, median and peak EMG levels were higher in left than in right forearm muscles with left ECU presenting the highest peak load of 30 %MVE. Females demonstrated a higher muscle activity than males, but this was in accordance with differences in anthropometric measures.

这项研究的目的是探究不同小提琴曲目中的肌肉活动水平，量化上肢两侧双侧的总体水平，并评估肌肉活动与人体测量学特征之间的关联。在18位熟练的小提琴演奏者中，分别在A和E大尺度上从斜方肌（UT），趾浅屈肌（FDS），尺伸腕（ECU），趾伸腕（EDC）和radial腕腕（ECR）双向记录了表面肌电图演奏三个八度和莫扎特的小提琴协奏曲。5.为了比较侧差，根据幅度概率分布函数（APDF）计算了肌肉活动的静态，中位和峰值水平。这项研究表明，作为标准任务使用的音阶可以用来估计小提琴演奏期间的平均肌肉活动。通过对音阶和音乐作品的结果进行比较，可以发现音乐作品和E大音阶中所有肌肉的肌肉活动都相似。左前ECU的静态，中值和峰值肌电图水平高于右前臂肌肉，其中左ECU的最高峰值负荷为30％MVE。女性表现出比男性更高的肌肉活动，但这与人体测量学方法的差异一致。
