摘要

背景:老年股骨近端骨折患者术后早期体育活动可降低死亡率。我们假设活动追踪器可以可靠、客观地监测院内活动,与功能独立性和生活质量相关。方法:在22例患者的三个位置(手腕、脚踝和股骨)记录三种不同类型的跟踪器(Fitbit™flex、Misfit™Shine和Axivity AX3)的步数和信号矢量大小(SVM)。年龄81±8岁,男女平均,ASA评分2.5±0.6。单一协议的活动事件(n = 191)临床分为4个级别,并与监测信号相关。术后2±1天和8±3天,EuroQol-5D和Barthel-20指数补充了这一数据。结果:所有腕部测量(Fitbit, Misfit)的精度都无法接受;然而,在脚踝处使用Misfit,灵敏度和特异性达到90%左右。应用此组合,实际步长与测量步长之间的相关性(R2 = 0.99)与类别判别之间的相关性具有统计学意义(p < 0.002)。判别分析的特点是计算基于支持向量机测量的四个活动水平,使用Axivity跟踪器在股骨。聚类分析显示临床观察和计算的活动水平100%一致。术后各分析时间点活动分钟数或活动量、EuroQol-5D和Barthel-20指数均显著升高。然而,只有Barthel-20与测量的活动水平相关(p < 0.01)。结论:Misfit和Axivity追踪器能可靠地监测老年股骨近端骨折术后患者的活动情况。然而,磨损位置是决定性的。客观测量的活动与功能独立性和生活质量相关。

Validation of Activity Tracking Procedures in Elderly Patients after Operative Treatment of Proximal Femur Fractures.

Background: Early postoperative physical activity in elderly patients suffering from proximal femoral fractures may reduce mortality. We hypothesized that activity trackers can reliably and objectively monitor the in-hospital mobilization, correlating with functional independence and quality of life.

Methods: Three different tracker types (Fitbit™ flex, Misfit™ Shine, and Axivity AX3) at three locations (wrist, ankle, and femur) recorded steps and signal vector magnitudes (SVM) in 22 patients. They were 81 ± 8 years old, were equally distributed between the sexes, and had an ASA score of 2.5 ± 0.6. Single protocoled activity events (n = 191) were clinically categorized into 4 levels and correlated with the monitored signals. Additionally, 2 ± 1 and 8 ± 3 days after the operation, the EuroQol-5D and the Barthel-20 index supplemented this data.

Results: All measurements at the wrist (Fitbit, Misfit) resulted in unacceptable accuracy; however, sensitivity and specificity reached around 90% using the Misfit at the ankle. Applying this combination, the correlation between real and measured steps (R2 = 0.99) and the category discrimination were statistically significant (p < 0.002). A discriminant analysis featured the calculation of four activity levels based on SVM measurements using the Axivity tracker at the femur. A cluster analysis showed a 100% agreement between the clinically observed and the calculated activity levels. The amount of active minutes or periods and both the EuroQol-5D and the Barthel-20 indices significantly increased between the analyzed time points after the operation. However, only the Barthel-20 was associated with the measured activity levels (p < 0.01).

Conclusion: The Misfit and the Axivity trackers can reliably monitor activity in elderly patients after operative treatment of proximal femur fractures. However, the wear location is decisive. Objectively measured activity correlated with functional independence and quality of life.

期刊介绍: Rehabilitation Research and Practice is a peer-reviewed, Open Access journal that publishes original research articles, review articles, and clinical studies in all areas of physical medicine and rehabilitation. The journal focuses on improving and restoring functional ability and quality of life to those with physical impairments or disabilities. In addition, articles looking at techniques to assess and study disabling conditions will be considered.
