BACKGROUND
The purpose of this study was to use at-home, portable, continuous monitoring technologies to record arm motion and activity preoperatively and postoperatively after reverse total shoulder arthroplasty (RTSA).
METHODS
Thirty-three patients indicated for RTSA were monitored preoperatively and 3 and 12 months postoperatively. Inertial measurement units were placed on the sternum and upper arm of the operative limb, recording humeral motion relative to the torso for the duration of a waking day. Elevation events per hour (EE/h) > 90°, time spent at >90°, and activity intensity were calculated and compared between time points. Patient-reported outcome measures were also collected at all time points.
RESULTS
At 3 (P = .040) and 12 (P = .010) months after RTSA, patients demonstrated a significantly greater number of EE/h > 90° compared with preoperatively. There were no significant differences (P ≥ .242) in the amount of time spent at different elevation angles at any time point or in arm activity intensity. Overall, 95% of the day was spent at elevation angles < 60°, and 90% of the day was spent in a low- or moderate-intensity state. Pearson correlations demonstrated relationships between forward elevation and the number of EE/h (r = 0.395, P = .001) and the number of EE/h > 90° (r = 0.493, P < .001).
CONCLUSION
After RTSA, patients significantly increase the frequency of arm elevation to higher angles. However, we found no differences in the amount of time spent at different elevation angles. Overall, after RTSA, >95% of the day was spent at elevation angles < 60° and <1% of the day was spent at >90° of elevation.
背景
本研究的目的是使用家庭便携式连续监测技术记录全肩关节置换术（RTSA）术前和术后的手臂运动及活动情况。
方法
对33例拟行RTSA的患者进行术前、术后3个月和12个月的监测。将惯性测量单元放置在手术侧肢体的胸骨和上臂上，记录清醒一天中肱骨相对于躯干的运动情况。计算并比较各时间点每小时抬高事件（EE/h）>90°的次数、在>90°角度停留的时间以及活动强度。同时在所有时间点收集患者报告的结局指标。
结果
RTSA术后3个月（P = 0.040）和12个月（P = 0.010）时，患者每小时EE/h>90°的次数较术前显著增加。在任何时间点，不同抬高角度的停留时间或手臂活动强度均无显著差异（P≥0.242）。总体而言，一天中95%的时间处于<60°的抬高角度，90%的时间处于低强度或中等强度状态。Pearson相关性分析显示前屈抬高与EE/h次数（r = 0.395，P = 0.001）以及EE/h>90°的次数（r = 0.493，P<0.001）之间存在关联。
结论
RTSA术后，患者将手臂抬高到更高角度的频率显著增加，但我们发现不同抬高角度的停留时间并无差异。总体而言，RTSA术后，一天中>95% 的时间处于<60°的抬高角度，<1% 的时间处于>90°的抬高角度。
