本研究旨在通过加速度计阐明全膝关节置换术（TKA）对膝关节骨性关节炎患者躯干波动和步态规律的影响。参与者包括18名接受TKA的膝关节骨关节炎患者。通过连接在颈部和腰椎区域的三轴加速度计评估tka前后舒适速度下的步态。术后4周进行tka后测量。主干波动由加速度的均方根（RMS）和均方根比（各方向均方根与总均方根的比值）估计。利用自相关函数估计步态的规律性。结果表明，TKA显著降低了颈腰椎区域中外侧加速的RMS比，降低了步态的规律性。TKA似乎通过改善膝关节功能来减少躯干代偿运动。使用加速度计评估躯干波动对tka前后膝关节骨性关节炎患者的临床评估是有用的。
This study aimed to clarify the effect of total knee arthroplasty (TKA) on trunk fluctuation and regularity of gait in patients with knee osteoarthritis by an accelerometer. The participants included 18 patients with knee osteoarthritis undergoing TKA. The gait at a comfortable velocity was assessed pre- and post-TKA by a triaxial accelerometer attached to the neck and lumbar regions. Measurement post-TKA was performed 4 weeks after surgery. Trunk fluctuation was estimated by the root mean square (RMS) of acceleration and RMS ratio (the ratio of RMS in each direction to the total RMS). Regularity of gait was estimated using the autocorrelation function. The results showed that TKA significantly decreased the RMS ratio in mediolateral acceleration of the neck and lumbar regions and reduced gait regularity. TKA appears to reduce compensatory trunk motion through the improvement of knee function. An assessment of trunk fluctuation using an accelerometer is useful for the clinical assessment of patients with knee osteoarthritis pre- and post-TKA.
