背景肩胛肌强化训练用于治疗与肩损伤相关的肩胸功能障碍。考虑到这些患者经常出现肌间和肌内失衡，建议进行促进下腹肌（LT）、中腹肌（MT）和前锯肌（SA）激活的运动，同时尽量减少上腹肌（UT）的活动。假设在12种常用的肌群强化练习中，可以根据低UT/LT、UT/MT或UT/SA肌肉比例进行肌肉平衡康复的选择。研究设计对照实验室研究。方法对45名健康受试者进行12种常用的肩胛骨运动，用表面肌电描记法测定其肩胛骨3个肌部和SA的肌电活动。结果对于每一肌内压比值（UT/LT，UT/MT），选择3种运动恢复肌肉平衡。侧卧位外旋、侧卧位前屈、俯卧位水平外展并外旋和俯卧位伸展运动被认为是最适合肌内正中肌平衡康复的运动。对于UT/SA比率，没有一项运动符合最佳肌间平衡恢复的标准。结论在臀肌失衡的情况下，某些运动优于其他运动，因为它们的UT/LT和UT/MT比值较低。临床相关性在选择康复锻炼时，临床医生应优先选择LT和MT活性高而UT活性低的锻炼。
Background Strengthening exercises for the scapular muscles are used in the treatment of scapulothoracic dysfunction related to shoulder injury. In view of the intermuscular and intramuscular imbalances often established in these patients, exercises promoting lower trapezius (LT), middle trapezius (MT), and serratus anterior (SA) activation with minimal activity in the upper trapezius (UT) are recommended. Hypothesis Of 12 commonly used trapezius strengthening exercises, a selection can be performed for muscle balance rehabilitation, based on a low UT/LT, UT/MT, or UT/SA muscle ratio. Study Design Controlled laboratory study. Methods Electromyographic activity of the 3 trapezius parts and the SA was measured in 45 healthy subjects performing 12 commonly described scapular exercises, using surface electromyography. Results For each intramuscular trapezius ratio (UT/LT, UT/MT), 3 exercises were selected for restoration of muscle balance. The exercises side-lying external rotation, side-lying forward flexion, prone horizontal abduction with external rotation, and prone extension were found to be the most appropriate for intramuscular trapezius muscle balance rehabilitation. For the UT/SA ratio, none of the exercises met the criteria for optimal intermuscular balance restoration. Conclusion In cases of trapezius muscle imbalance, some exercises are preferable over others because of their low UT/LT and UT/MT ratios. Clinical Relevance In the selection of rehabilitation exercises, the clinician should have a preference for exercises with high activation of the LT and MT and low activity of the UT.
