Abstract

Accurate measurement of internal/external rotation joint angle is critical in assessing the shoulder function, especially in the clinical practice as it plays a key role in evaluating activities of daily living and monitoring the rehabilitation progress. This study analyzed the effectiveness of using a marker cluster placed over the proximal epiphysis of the ulna to measure humeral axial rotation with respect to the thorax, comparing it with the traditional method that uses a cluster placed on the upper arm. Data were collected simultaneously using the proposed indirect approach and a conventional marker cluster to analyze three internal/external rotations performed in the Ski-Pose, frontal, and sagittal plane. Linear regressions for time series comparison reported a coefficient of determination R² > 0.9919 in all tasks. The linear coefficients (a₁) were as follows: Ski-Pose (a₁ = 0.64 ± 0.10), frontal plane (a₁ = 0.74 ± 0.05), and sagittal plane (a₁ = 0.73 ± 0.04). Three additional planar tasks were recorded for concurrent validity and RMSE was reported for the main joint angle, obtaining a maximum of 3.87° for the pure flexion/extension task and 1.94° for the abduction/adduction task. A forearm pronation/supination task without axial rotation yielded a maximum error standard deviation of 2.64°. Proximal ulna tracking showed a statistically higher maximum range of motion than humeral tracking in pure axial rotation tasks. This indirect tracking approach is a promising alternative to the traditional cluster technique due to its reduced sensitivity to soft tissue artifacts.

通过近端尺骨标记簇测量肱骨轴向旋转

准确测量内/外旋转关节角度对评估肩关节功能至关重要，特别是在临床实践中，它对评估日常生活活动和监测康复进展起着关键作用。本研究分析了使用放置在尺骨近端骨骺上的标记簇来测量肱骨相对于胸腔的轴向旋转的有效性，并将其与使用放置在上臂的标记簇的传统方法进行了比较。数据采用间接方法和传统标记聚类同时收集，以分析在Ski-Pose、正面和矢状面进行的三种内/外旋转。线性回归对时间序列比较的决定系数R2 >；在所有任务中为0.9919。线性系数a1分别为：Ski-Pose （a1 = 0.64±0.10）、额位面（a1 = 0.74±0.05）、矢状面（a1 = 0.73±0.04）。另外三个平面任务记录了并发效度，报告了主关节角的RMSE，纯屈伸任务的RMSE最大值为3.87°，外展/内收任务的RMSE最大值为1.94°。无轴向旋转的前臂旋前/旋后任务的最大误差标准偏差为2.64°。在纯轴向旋转任务中，近端尺骨跟踪比肱骨跟踪显示统计上更高的最大运动范围。由于对软组织伪影的敏感性降低，这种间接跟踪方法是传统聚类技术的一种有希望的替代方法。
