肩胛骨凹陷的位置会使上斜方肌区域保持拉长的位置，导致过度紧张。这种压力可能会导致受影响区域的周围伤害性神经敏感，从而改变压痛阈值 (PPT)。因此，与肩胛骨垂直位置正常的受试者相比，肩胛骨凹陷对齐错误的人在上斜方肌区域的 PPT 水平可能较低。这项双盲研究的目的是评估年轻健康人群中肩胛骨位置对斜方肌上部区域 PPT 的影响。巴西米纳斯吉拉斯天主教大学 - PUC-米纳斯的 52 名物理治疗学生自愿参加这项研究，他们的肩部正常（NS 组，n = 26，6 名男性和 20 名女性）或肩部凹陷（DS 组，n = 26，6 名男性和 20 名女性）。使用电子压力计测量上斜方肌区域的 PPT。结果显示组间存在显着差异，DS 组 (19.0 +/- 9.0 N/cm(2)) 的平均 PPT 值低于 NS 组 (26.1 +/- 19.6 N/cm(2)) (p < 0.01)。我们的结果表明，与肩胛骨位置正常的受试者相比，肩胛骨位置凹陷的健康年轻受试者的上斜方肌 PPT 值显着较低。 (c) 2007 年国际疼痛研究协会欧洲分会联合会。由爱思唯尔有限公司出版。保留所有权利。
A position of scapula depression will maintain the upper trapezius muscle region in a lengthened position, causing excessive strain. This strain could lead to peripheral nociceptive nerves sensitization in the affected area, changing the pressure pain threshold (PPT). Thus, people with a faulty alignment of scapular depression may have lower PPT levels in the upper trapezius region when compared to subjects with normal vertical scapular position. The purpose of this double-blind study was to assess the influence of scapular position on the PPT of the upper trapezius region in a young healthy population. Fifty two physical therapy students of the Catholic University of Minas Gerais - PUC-Minas, Brazil, with normal shoulder (NS group, n = 26, 6 men and 20 women) or depressed shoulder (DS group, n = 26, 6 men and 20 women) volunteered to participate in this study. An electronic pressure algometer was used to measure the PPT on the upper trapezius muscle region. The results showed a significant difference between groups, with the DS group (19.0 +/- 9.0 N/cm(2)) demonstrated lower mean PPT values when compared to NS group (26.1 +/- 19.6 N/cm(2)) (p < 0.01). Our results showed that healthy young subjects with depressed scapula position had significant lower upper trapezius PPT values when compared to subjects with normal scapula position.
