To investigate if there is a difference in muscle activity patterns during high load plyometric shoulder exercises between overhead athletes with and without shoulder pain.
Controlled laboratory EMG study.
University EMG Laboratory.
Sixty overhead athletes, 30 with shoulder pain and 30 healthy controls were included.
The EMG activity of Upper Trapezius (UT), Middle Trapezius (MT), Lower Trapezius (LT), Serratus Anterior (SA), Latissimus Dorsi (LD) and Pectoralis Major (PM) on the tested side and bilateral on Abdominal Obliques Externus (OE) muscles was registered with wireless surface EMG during 3 rotational plyometric shoulder exercises in 3 positions, prone, sidelying and standing.
A significant higher muscle activity was found in the shoulder pain group for MT together with an overall significant higher activity in the thoraco-humeral and abdominal muscles compared to healthy controls.
When rehabilitating the overhead athlete with shoulder pain, shoulder muscles together with both thoraco-humeral and abdominal muscles need to be engaged.
研究在进行高负荷的增强式肩部练习时，患有肩部疼痛和无肩部疼痛的 overhead 运动员之间肩部肌肉活动模式是否存在差异。
对照实验室肌电图研究。
大学肌电图实验室。
共纳入 60 名 overhead 运动员，其中 30 名患有肩部疼痛，30 名健康对照。
在 3 种体位（俯卧位、侧卧位和站立位）下，使用无线表面肌电图记录了 3 种旋转增强式肩部练习时测试侧和双侧腹外斜肌（OE）的上斜方肌（UT）、中斜方肌（MT）、下斜方肌（LT）、前锯肌（SA）、背阔肌（LD）和胸大肌（PM）的肌电活动。
肩部疼痛组的 MT 肌肉活动明显更高，与健康对照组相比，胸肩和腹部肌肉的整体活动明显更高。
在对患有肩部疼痛的 overhead 运动员进行康复时，需要同时锻炼肩部肌肉以及胸肩和腹部肌肉。
