研究概览
简要总结
This study will analyze and compare scapular kinematics and muscle activation patterns between upper string musicians with and without neck pain during arm elevation and playing tasks (open strings, scales, musical pieces), providing insights for performance training and rehabilitation programs to reduce playing-related musculoskeletal disorders.
详细描述
The study participants will be right-handed upper string musicians (violinists and violists) aged 18 years and older. Participants must have at least 5 years of playing experience and practice more than 6 hours per week.
Neck pain group: non-specific neck pain (between superior nuchal line and T1) lasting at least 2 weeks with NRS ≥3.
Healthy control group: no neck/shoulder pain history in the past year, matched for age, gender, handedness, playing experience (>5 years), and practice hours (>6 hours/week).
The study involves arm elevation (0°, 30°, 60°, 90°, 120°); open string playing (at 60-120 bpm); A major scale (at 60-120 bpm); E major scale (at 60-120 bpm); and Vittorio Monti Csárdás.

入选标准
- •Age ≥ 18 years old.
- •Having at least 5 years of string instrument playing experience and practicing for more than 6 hours per week.
- •For the neck pain group: Experiencing non-specific neck pain for at least 2 weeks, with pain located between the superior nuchal line and the T1 spinous process, and a pain intensity of at least 3 on the Numeric Rating Scale (NRS ≥ 3).
- •For the healthy control group: Having no history of neck or shoulder pain within the past year (matched with the neck pain group by age, gender, and handedness).
排除标准
- •History of any neck or shoulder surgery or fracture.
- •Experiencing pain below the elbow with an intensity of at least 3 (NRS ≥ 3).
- •Diagnosed history of any structural cervical spine issues, such as herniation of intervertebral disc (HIVD), cervical spine spondylosis, or spondylolisthesis.
- •Positive response on any of the following 5 cervical spine screening tests: cervical distraction test, Spurling's test, Valsalva test, rotational alar ligament stress test, or Sharp-Purser test.
- •Any neurological disorders.
- •Pregnancy during the study period.

结局指标
主要结局
Scapular muscles activation during arm elevation and dynamic instrument-playing tasks.
时间窗: Through study completion, an average of 1 hour
Muscle activation levels of the upper trapezius, lower trapezius, and serratus anterior will be measured using surface electromyography (sEMG) during arm elevation (0°, 30°, 60°, 90°, 120°) and dynamic instrument-playing tasks. Data will be normalized to maximum voluntary isometric contraction (%MVIC) and expressed as root mean square (RMS) amplitude.
Scapular kinematics during arm elevation and dynamic instrument-playing tasks
时间窗: Through study completion, an average of 1 hour
Three-dimensional scapular orientation (upward/downward rotation, internal/external rotation, anterior/posterior tilt) will be measured using an electromagnetic tracking system during arm elevation (0°, 30°, 60°, 90°, 120°) and dynamic instrument-playing tasks. Data will be expressed in degrees.
次要结局
- Cervical muscles activation during arm elevation and dynamic instrument-playing tasks(: Through study completion, an average of 1 hour)
- Cervical kinematic during arm elevation and dynamic instrument-playing tasks(Through study completion, an average of 1 hour)
- Shoulder muscle strength(Immediately during the experiment)
- Cervical and Shoulder mobility(Immediately during the experiment)
- Shoulder muscle length test(Immediately during the experiment)
- Postural Angles (CVA and FSA)(Immediately during the experiment)
