Cross-sectional clinical measurement study.
Inferior mobilizations are used to treat patients with shoulder dysfunctions. Common positions recommended for promoting an inferior glide include: (1) an open-packed position (OPP) in which the shoulder is in 55° of abduction, 30° of horizontal adduction, and no rotation; (2) neutral position (NP) of the shoulder; and (3) position of 90° of shoulder abduction (ABDP). Studies comparing the impact of position on inferior mobilization are lacking.
To determine the effect of shoulder position on humeral movement and mobilization force during inferior mobilizations.
Twenty-three subjects were tested bilaterally. Subjects were placed in the OPP, and an ultrasound transducer placed over the superior glenohumeral joint. As inferior mobilization forces were applied through a dynamometer, ultrasound images were taken at rest and during 3 grades of inferior mobilization. This process was repeated in the NP and the ABDP.
In the NP, movements during grade 1, 2, and 3 mobilizations were 1.8, 3.8, and 4.5 mm, respectively. Movements measured in the OPP (1.0, 2.4, and 3.6 mm, respectively) and in the ABDP (1.0, 2.2, and 2.3 mm, respectively) were less. Forces were higher in the NP during grade 1, 2, and 3 mobilizations (51.8, 138.7, and 202.1 N, respectively) than in the OPP (37.2, 91.2, and 139.9 N, respectively) and the ABPD (42.5, 115.3, and 165.5 N, respectively).
Mobilization position altered the movement and force during inferior mobilizations.
Shoulder position should be considered when utilizing inferior mobilizations.

横截面临床测量研究。
下向松动术用于治疗肩部功能障碍患者。促进下向滑动的常见推荐位置包括：（1）张开位（OPP），肩部外展 55°，水平内收 30°，无旋转；（2）肩部中立位（NP）；（3）肩部外展 90°（ABDP）。比较位置对下向松动影响的研究尚缺乏。
确定肩部位置对下向松动时肱骨运动和松动力的影响。
对 23 名受试者进行双侧测试。受试者置于 OPP 位置，在肩峰上关节上方放置超声换能器。当通过测力计施加下向松动力时，在休息时和 3 级下向松动时拍摄超声图像。在 NP 和 ABDP 中重复此过程。
在 NP 中，在 1 级、2 级和 3 级松动时的运动分别为 1.8、3.8 和 4.5 毫米。在 OPP（分别为 1.0、2.4 和 3.6 毫米）和 ABDP（分别为 1.0、2.2 和 2.3 毫米）测量的运动较小。在 NP 中，在 1 级、2 级和 3 级松动时的力分别为 51.8、138.7 和 202.1 N，高于 OPP（分别为 37.2、91.2 和 139.9 N）和 ABDP（分别为 42.5、115.3 和 165.5 N）。
松动位置改变了下向松动时的运动和力。
在使用下向松动术时应考虑肩部位置。
