Frozen shoulder (FS) is one of the most common shoulder conditions characterized by pain, restricted range of motion and high morbidity. Though FS is known as adhesive capsulitis, presence of capsular adhesions has been rebutted and the nomenclature adhesive capsulitis is debated. It has been proposed that FS is a condition of cytokine driven capsular, ligamentous fibrosis and contracture. Despite extensive research on it, still it is unclear that how far the capsular contracture contribute to range of motion restriction in FS. Evidence also suggested that myofascial trigger points play a role in restricted range of motion.
To find an association between subscapularis trigger point and frozen shoulder.
Cross-sectional study.
143 Patients were screened for inclusion and exclusion criteria, out of which 100 patients, were selected for the study. Manual palpation was performed to look for subscapularis muscle trigger points via axillary approach on both the affected and unaffected side. Trigger point diagnosing criteria was used to diagnose subscapularis trigger points.
Results have shown that there was an association between subscapularis trigger point and frozen shoulder (X 2 = 32.151 P < 0.0001) on the affected side. We used Phi coefficient to measure the degree of association which denotes (Phi = 0.567 P < 0.0001) strong association between frozen shoulder and subscapularis trigger point on the affected side compared to unaffected side (X 2 9.157; P < 0.002: Phi:0.303: P < 0.002).
This study concluded that there appears to be a strong association between subscapularis trigger point and frozen shoulder.
冻结肩（FS）是最常见的肩部疾病之一，其特征为疼痛、活动范围受限和高发病率。尽管 FS 被称为粘连性肩关节囊炎，但囊粘连的存在已被反驳，粘连性肩关节囊炎的命名也存在争议。有人提出 FS 是一种由细胞因子驱动的囊、韧带纤维化和挛缩的疾病。尽管对其进行了广泛的研究，但仍然不清楚囊挛缩对 FS 活动范围受限的影响程度。有证据表明，肌筋膜触发点在活动范围受限中起作用。
探讨肩胛下肌触发点与冻结肩的关系。
横断面研究。
对 143 例患者进行筛选，纳入和排除标准，其中 100 例患者被纳入研究。通过腋路对双侧肩胛下肌进行触诊，寻找肩胛下肌触发点。采用触发点诊断标准诊断肩胛下肌触发点。
结果表明，冻结肩与肩胛下肌触发点之间存在关联（X 2 = 32.151，P < 0.0001）。我们使用 Phi 系数来衡量关联程度，结果显示在患侧，冻结肩与肩胛下肌触发点之间存在强烈关联（Phi = 0.567，P < 0.0001），而在健侧，两者之间的关联较弱（X 2 = 9.157，P < 0.002；Phi = 0.303，P < 0.002）。
本研究表明，肩胛下肌触发点与冻结肩之间似乎存在强烈关联。
