背景：绝经后妇女随着体质的下降，容易发生跌倒和骨折。桡骨远端骨折（DRF）被认为是原发性脆性骨折，患有这种骨折的女性在通常的定时起身和行走（TUG）测试中表现出较差的结果，表明平衡和体能下降。女性DRF患者的详细身体特征尚未得到广泛研究。研究问题：新型激光TUG系统是否能够检测和分析身体能力有下降趋势的DRF患者的详细步态特征？研究方法：在这项横断面病例对照研究中，对32例接受手术治疗的女性DRF患者在术后2周使用激光TUG系统进行步态特征评估，以分析正常TUG测试期间的详细腿部运动。43名年龄和性别匹配的非骨折妇女作为对照组进行了评价的激光TUG系统。在TUG测量时纠正了生活方式和当前疾病。结果：DRF患者TUG检查速度慢，完成TUG检查的步数多。此外，观察到不对称轨迹和距标记的显著更远距离。意义：激光TUG系统检测DRF患者详细的步态特征。步态的下降和异常可能是连续性脆性骨折的原因之一。为了防止继发性脆性骨折，该系统可用于筛查。
Background: Postmenopausal women are at risk of fall and fracture with the physical decline. Distal radius fracture (DRF) is considered as the primary fragility fracture, and women with this fracture showed poor results in the usual Timed Up-and-Go (TUG) test, indicating a decline in balance and physical ability. The detailed physical characteristics of female DRF patients have not been extensively examined. Research question: Is the novel laser TUG system able to detect and analyze the detailed gait characteristics in patients with DRF whose physical ability has tended to decline?Methods: In this cross-sectional case control study, the gait characteristics of 32 female patients with DRF who had undergone surgery were evaluated at 2 weeks postoperatively with a laser TUG system to analyze the detailed leg motion during normal TUG test. Forty-three age- and sex-matched non-fractured women were evaluated by the laser TUG system as controls. Lifestyle and present illness were corrected at the time of TUG measurement. Detailed data during laser TUG in both groups were compared statistically, and odds ratio and thread shod of the fracture was elucidated through a logistic regression analysis.Results: DRF patients showed slower speed and had to do more steps to complete the TUG test. Furthermore, asymmetric trajectory and signi ficantly further distance from the marker were observed. Thirteen steps to complete the TUG test was the thread shod of DRF.Significance: Detailed gait characteristics of patients with DRF were detected by the laser TUG system. The gait decline and abnormality could be one of the reasons of consecutive fragility fracture. To prevent secondary fragility fractures, this system can be useful for screening.
