The aim of this study was to assess static balance in patients with lumbar spinal canal stenosis who qualified for surgical decompression of associated neural structures and compare them with asymptomatic participants.
This case-controlled study evaluated a sample of 50 patients with spinal canal stenosis (stenosis group) and 48 participants with no history of clinical symptoms of back pain. Static balance was assessed by conducting quantitative analysis of balance reaction parameters in quiet standing with the eyes closed.
Higher values were observed in total length of center of pressure (COP) path, length of COP path in the anterior-posterior plane, mean amplitude of COP projection in the anterior-posterior plane, maximal amplitude between the 2 most distant points in the anterior-posterior plane, mean COP velocity, and sway area marked by the moving COP in the stenosis group compared with the asymptomatic group.
This study showed statistically significant differences in static balance parameters between patients with spinal canal stenosis compared with the asymptomatic group.
本研究旨在评估符合相关神经结构手术减压条件的腰椎管狭窄症患者的静态平衡，并将其与无症状参与者进行比较。
本病例对照研究评估了50例椎管狭窄患者（狭窄组）和48例无背痛临床症状史的参与者样本。通过对闭眼安静站立时平衡反应参数进行定量分析来评估静态平衡。
与无症状组相比，狭窄组的压力中心（COP）路径总长度、前后平面COP路径长度、前后平面COP投影平均幅度、前后平面两个最远点之间的最大幅度、平均COP速度以及移动COP标记的摆动面积的值更高。
本研究表明，与无症状组相比，椎管狭窄患者的静态平衡参数存在统计学上的显著差异。
