PURPOSE/BACKGROUND: The sleeper stretch is a common intervention prescribed for individuals with decreased glenohumeral internal rotation. Passive glenohumeral internal rotation (GHIR) when quantified in sidelying has been suggested to be a more reliable measure as compared to measurments performed in supine with the humerus abducted to 908. Recently, the sidelying position has also been proposed as an evaluative measure to quantify GHIR. Minimal work however has described mean GHIR values in sidelying. Therefore, the objective of this study was to establish preliminary mean passive GHIR values in sidelying for a healthy, college-age population. Secondary purposes were to ascertain if mean values were affected by upper extremity dominance or sex.
Using a standardized protocol, passive GHIR was measured using a digital inclinometer on the dominant and non-dominant shoulders of 60 healthy, college-age participants (32 female [20.66±1.15 years, 170.70±14.38 cm, 63.34±7.51 kg] and 28 male [21.50±1.40 years, 183.81±13.17 cm, 90.04±17.91 kg]).
The sidelying passive GHIR grand mean for all participants bilaterally was 50.4 ± 11.78. Mean passive GHIR values on the non-dominant side (52.7 ± 10.28) were greater than those on the dominant side (48.0 ± 12.58) (p = 0.002). There was no difference when GHIR values were compared by sex (p = 0.327) and a significant interaction between UE dominance and sex was not apparent (p = 0.693).
In a healthy college age population, these preliminary data suggest GHIR values are statistically greater on the non-dominant side and that sex does not significantly affect GHIR measures in a sidelying position.

目的/背景：睡眠者拉伸是针对盂肱关节内旋减少的个体所规定的常见干预措施。与在仰卧位将肱骨外展至90°时进行的测量相比，在侧卧位对被动盂肱关节内旋（GHIR）进行量化被认为是一种更可靠的测量方法。最近，侧卧位也被提议作为量化GHIR的一种评估措施。然而，很少有研究描述侧卧位时的平均GHIR值。因此，本研究的目的是为健康的大学生群体确定侧卧位时的初步被动GHIR平均值。次要目的是确定平均值是否受上肢优势或性别的影响。
采用标准化方案，使用数字倾角仪对60名健康的大学生参与者（32名女性[20.66±1.15岁，170.70±14.38厘米，63.34±7.51千克]和28名男性[21.50±1.40岁，183.81±13.17厘米，90.04±17.91千克]）的优势肩和非优势肩进行被动GHIR测量。
所有参与者双侧的侧卧位被动GHIR总体平均值为50.4±11.78。非优势侧的平均被动GHIR值（52.7±10.28）大于优势侧（48.0±12.58）（p = 0.002）。按性别比较GHIR值时无差异（p = 0.327），上肢优势和性别之间无明显的显著交互作用（p = 0.693）。
在健康的大学生群体中，这些初步数据表明非优势侧的GHIR值在统计学上更高，并且性别在侧卧位时不会显著影响GHIR测量值。
