In order to classify and analyze the parameters of upper body posture, a baseline in the form of standard values is demanded. To this date, standard values have only been published for healthy men aged 18-35 and 41-50 years. Data for male adults aged between 31 and 40 years are lacking.
The postural parameters of 101 symptom-free male volunteers aged 31-40 (35.58 ± 2.88) years were studied. The mean height of the men was 179.89 ± 7.38 cm, with a mean body weight of 86.36 ± 11.58 kg and an average BMI of 26.70 ± 3.35 kg/m. By means of video rasterstereography, a 3-dimensional scan of the upper back surface was measured in a habitual standing position. The means or medians, confidence interval, tolerance range, and group comparisons and correlations of BMI and physical activity were calculated for all parameters.
The habitual standing position was found to be almost symmetrical and the axis aligned in the spine, pelvis, and shoulder region, while the spine position was marginally inclined ventrally. The kyphosis angle of the thoracic spine was greater than the lordosis angle of the lumbar spine. All deviations fell under the measurement error margin of 1 mm/1°. The greater the BMI, the greater was the pelvic and scapular distance. The lower the BMI, the further caudally positioned was the right shoulder. The pelvic and scapular distances were also lower with the increasing athleticism of the participants.
The upper body posture of men between the ages of 31 and 40 years was found to be almost symmetrical and axis-conforming, with the kyphosis angle, pelvic distance, and shoulder distance enlarging with increasing BMI. Consequently, postural parameters presented in this survey allow for comparisons with other studies, as well as the evaluation of clinical diagnostics and applications.
为了对上身姿势参数进行分类和分析，需要有标准值形式的基线。迄今为止，仅为 18-35 岁和 41-50 岁的健康男性发布了标准值。缺乏 31-40 岁男性成年人的数据。
研究了 101 名无症状男性志愿者（35.58 ± 2.88）岁的姿势参数。男性的平均身高为 179.89 ± 7.38 厘米，平均体重为 86.36 ± 11.58 千克，平均 BMI 为 26.70 ± 3.35 千克/平方米。通过视频光栅立体摄影术，在习惯性站立位置对上身背面的 3 维扫描进行了测量。计算了所有参数的 BMI 和体力活动的平均值或中位数、置信区间、容差范围以及组间比较和相关性。
发现习惯性站立姿势几乎是对称的，脊柱、骨盆和肩部区域的轴对齐，而脊柱位置略微向腹侧倾斜。胸椎的后凸角大于腰椎的前凸角。所有偏差均在 1 毫米/1°的测量误差范围内。BMI 越大，骨盆和肩胛距离越大。BMI 越低，右肩的尾侧位置越低。随着参与者运动能力的提高，骨盆和肩胛距离也越低。
31-40 岁男性的上身姿势几乎是对称的，符合轴向，后凸角、骨盆距离和肩距随着 BMI 的增加而增大。因此，本研究中提出的姿势参数可与其他研究进行比较，也可用于临床诊断和应用的评估。
