Abstract

Background

Fracture determinants are falls, bone fragility, imbalance, and decreased lower limb strength. The timed up and go (TUG) test assesses most of the fracture determinants.

Aim

To assess the relationship between mobility status using TUG test, bone mineral density (BMD), and different fracture risks predicted by different tools.

Methods

A case (TUG time > 20 seconds)–control (TUG ≤ 20 seconds) study comprised 66 patients and 72 controls. Participants were assessed for falls, fracture history, and BMD using dual energy X-ray absorptiometry; the estimated 10-year fracture risk was also calculated using both the World Health Organization fracture risk assessment tool and Garvan fracture risk calculator.

Results

Patients had a lower femoral BMD (p = 0.009), T score (p = 0.003), and Z score (p = 0.001). Femur neck osteoporosis had a higher number of patients (p < 0.001). Patients also had lower lumbar BMD (p = 0.02), T-score (p = 0.02), and Z-score (p = 0.005). The estimated 10-year fracture risk for hip and other osteoporotic fractures were higher among the patients using both fracture risk assessment tool and Garvan calculators.

Conclusion

Poor TUG test results are associated with lower BMD and higher estimated 10 year fracture risk.

超越行动能力评估：定时测试及其与骨质疏松症和骨折风险的关系

骨折的决定因素是跌倒、骨骼脆弱、失衡和下肢力量下降。定时即用（TUG）测试评估了大多数骨折的决定因素。目的通过TUG测试评估活动状态、骨密度（BMD）和不同工具预测的不同骨折风险之间的关系。方法一项病例（TUG时间＞20秒）-对照（TUG≤20秒）研究包括66名患者和72名对照。使用双能X射线吸收仪评估参与者的跌倒、骨折史和BMD；还使用世界卫生组织骨折风险评估工具和Garvan骨折风险计算器计算了估计的10年骨折风险。结果患者股骨骨密度（p=0.009）、T评分（p=0.003）和Z评分（p=0.001）较低。股骨颈骨质疏松症患者数量较多（p<；0.001）。患者腰椎骨密度（p=0.02）、T分数（p=0.02）也较低，和Z评分（p=0.005）。在使用骨折风险评估工具和Garvan计算器的患者中，髋关节和其他骨质疏松性骨折的估计10年骨折风险更高。结论TUG测试结果不佳与骨密度较低和10年骨折风险较高有关。
