: Frozen shoulder is a common shoulder disorder that often places limitations on the range of motion of the shoulder. The disease may induce neck pain due to overuse of the neck muscle in an attempt to compensate for lack of shoulder movement. In clinical practice, swelling and inflammation of the scalene and levator scapulae may be detected via sonography in patients with frozen shoulder. The aim of this study was, therefore, to determine whether the involvement of the scalene complex or levator scapulae could compensate for the limited motion of the shoulder in patients with frozen shoulder. : We retrospectively reviewed the medical records of 362 patients with unilateral frozen shoulder. These patients were divided into four groups depending on the involvement of the scalene complex or levator scapulae muscle. The range of motion of the shoulder-encompassing flexion, abduction, and external rotation-was measured with a goniometer. We also performed an ultrasound scan on each shoulder. The involvement of the scalene complex and levator scapulae muscle was also assessed via musculoskeletal ultrasound. : The range of motion of the shoulder in terms of flexion, abduction, external rotation, and total range of motion differed significantly between the four groups ( < 0.05). Patients in whom the scalene complex or levator scapulae muscle was involved demonstrated a significantly wider range of motion in different shoulder directions than patients without the involvement of those muscles ( < 0.05). : A greater range of motion in the shoulder can be obtained through the activation of the scalene complex or levator scapulae muscle, which act to compensate for the lack of shoulder movement in patients with frozen shoulder. These two muscles showed thickening and hypoechoic changes upon sonography.
肩周炎是一种常见的肩部疾病，常常限制肩部的活动范围。该疾病可能会因颈部肌肉过度使用以试图补偿肩部活动受限而诱发颈部疼痛。在临床实践中，通过超声检查可在肩周炎患者中检测到斜角肌和肩胛提肌的肿胀和炎症。因此，本研究的目的是确定斜角肌复合体或肩胛提肌的受累是否可以补偿肩周炎患者肩部的活动受限。
我们回顾性分析了362例单侧肩周炎患者的病历。根据斜角肌复合体或肩胛提肌的受累情况，将这些患者分为四组。使用量角器测量包括前屈、外展和外旋的肩部活动范围。我们还对每个肩部进行了超声扫描。通过肌肉骨骼超声评估斜角肌复合体和肩胛提肌的受累情况。
四组之间在肩部前屈、外展、外旋和总活动范围方面存在显著差异（<0.05）。与未累及这些肌肉的患者相比，累及斜角肌复合体或肩胛提肌的患者在不同肩部方向上的活动范围明显更宽（<0.05）。
通过激活斜角肌复合体或肩胛提肌可以获得更大的肩部活动范围，这两块肌肉可代偿肩周炎患者肩部活动的不足。超声检查显示这两块肌肉出现增厚和低回声改变。
