Upper crossed syndrome (UCS) refers to specific altered muscle activation and changed movement patterns along with some postural deviations in the upper quarter of the body. This syndrome might contribute to the dysfunction of the cervicothoracic and glenohumeral joints. The present study will aim to investigate the effectiveness of a comprehensive corrective exercises program (CCEP) and subsequent detraining on alignment, muscle activation and movement pattern in men with UCS. This is a parallel-group randomized controlled trial. Participants will be 22 men aged 18 to 28 years who are suffering from UCS. Participants in the intervention group will conduct CCEP (three times a week for 8 weeks), followed by 4 weeks of detraining. The control group will do their daily activities. Participants will be randomized (1:1) into the intervention or the control group. The primary outcome will be upper trapezius activations. Secondary outcomes consist of electromyography of middle and lower trapezius and serratus anterior muscles, scapular dyskinesis test, forward head and shoulder angles, thoracic kyphosis angle, and neck flexion pattern test. We propose to evaluate the effectiveness of a randomized controlled trial of a CCEP in men with UCS on their alignment, selected muscle activations, and relevant movement patterns. Results from our trial may provide new insights into the effects of exercise not only on the alignment but also on muscle activation and movement patterns that are important outcomes for people with postural malalignments and, if successful, could assist therapists in evidence-based clinical decision-making.

一项综合矫正运动计划的有效性以及随后对上交叉综合症男性的对准，肌肉激活和运动方式的限制：一项平行组随机对照试验的方案

上交叉综合症（UCS）是指特定的肌肉激活改变和运动方式改变以及身体上四分之一体位的某些偏差。该综合征可能导致颈胸腔和盂肱关节功能障碍。本研究的目的是调查综合矫正锻炼计划（CCEP）的有效性，以及随后对UCS男性在对准，肌肉激活和运动方式方面的训练。这是平行组随机对照试验。参加者将是22名18至28岁的患有UCS的男性。干预组的参与者将进行CCEP（每周3次，共8周），然后进行4周的训练。对照组将进行日常活动。参与者将被随机分配（1：1）分为干预组或对照组。主要结果将是上斜方肌的激活。次要结果包括中斜方肌和下斜肌及前锯肌的肌电图，肩骨运动障碍试验，头肩前倾角，胸椎后凸角和颈部屈曲模式试验。我们建议评估CCEP对UCS男性患者的对准，选定的肌肉激活和相关运动方式的随机对照试验的有效性。我们的试验结果不仅可以为运动带来的影响提供新的见解，不仅可以对运动产生影响，而且可以对肌肉活动和运动方式产生影响，这对于姿势异常的人而言是重要的结果，如果成功，则可以帮助治疗师进行循证的临床决策，制造。伊朗临床试验注册处 IRCT20181004041232N1。2018年10月26日注册。
