Whether kinematic analysis of the trunk can provide useful clinical insight into the relationship between function and various spinal conditions is still under debate. The aim of this study was to develop a clinical protocol and an associated biomechanical model to characterize quantitatively the trunk movements in obese subjects.
Twenty (10 obese, 10 control) female subjects were evaluated with an optoelectronic system and passive markers attached to the spine during forward flexion, lateral bending, and rotation of the trunk.
We found a systematic error due to skin artifacts of less than 5 degrees in both groups. Intra- and inter-subject standard deviation was less than 6 degrees . Obese subjects demonstrated a significantly reduced motion in the thoracic spine associated with an increased pelvic tilt angle as compared to controls.
Our protocol was able to characterize trunk mobility in obese and normal subjects suggesting that kinematics could represent, even in an obese population, a promising method to investigate subclinical spinal disorders and to assess the effectiveness of rehabilitation programs.
躯干的运动学分析能否为功能与各种脊柱疾病之间的关系提供有用的临床见解仍存在争议。本研究的目的是制定一种临床方案和相关的生物力学模型，以定量表征肥胖受试者的躯干运动。
20名女性受试者（10名肥胖者，10名对照者）在躯干前屈、侧屈和旋转过程中，通过光电系统和附着在脊柱上的被动标记物进行评估。
我们发现两组中由于皮肤伪影导致的系统误差均小于5度。受试者内和受试者间的标准差均小于6度。与对照组相比，肥胖受试者胸椎运动明显减少，同时骨盆倾斜角度增加。
我们的方案能够表征肥胖和正常受试者的躯干活动度，这表明即使在肥胖人群中，运动学也可能是一种有前景的方法，用于研究亚临床脊柱疾病和评估康复计划的效果。
