[Purpose] The aim of this study was to evaluate the changes in reaching function during a reaching task in cervical spondylosis (CS) patients before and after surgery. [Participants and Methods] Nine patients participated in the study. Wrist acceleration peaks were monitored pre- and postoperatively using a tri-axial accelerometer, and the Japanese Orthopedic Association (JOA) score was recorded preoperatively. Additional upper extremity function tests were performed pre- and postoperatively. Multiple stepwise regression analysis was used to investigate the contribution of wrist acceleration peak to the severity of clinical symptoms. Moreover, we compared the acceleration peaks produced during the reaching task before and after surgery. [Results] Multiple regression analysis showed that wrist acceleration peak, grip strength and pinch strength were associated with the upper extremity function of the JOA score, explaining 61.0% of the variance. There was a significant improvement in x-axis acceleration peak after surgery. [Conclusion] Our results suggested that quantitative assessments of reaching function are useful to objectively evaluate the changes in reaching function in patients undergoing cervical decompression surgery.
[目的] 本研究旨在评估颈椎病（CS）患者手术前后在伸手任务中伸手功能的变化。[参与者与方法] 9名患者参与了本研究。术前和术后使用三轴加速度计监测腕部加速度峰值，并记录术前日本骨科协会（JOA）评分。术前和术后还进行了额外的上肢功能测试。采用多元逐步回归分析来研究腕部加速度峰值对临床症状严重程度的影响。此外，我们比较了手术前后伸手任务期间产生的加速度峰值。[结果] 多元回归分析表明，腕部加速度峰值、握力和捏力与JOA评分的上肢功能相关，解释了6方差的1.0%。术后x轴加速度峰值有显著改善。[结论] 我们的结果表明，对伸手功能进行定量评估有助于客观地评估接受颈椎减压手术患者伸手功能的变化。
