Prospective study.
To examine the changes in body sway using stabilometry in patients who underwent cervical laminoplasty for cervical myelopathy.
Although the patients of cervical myelopathy complain body sway there are few report to examine body sway objectively.
Patients who received treatment for cervical myelopathy between October 2010 and February 2013 were included. Twenty-one patients underwent cervical laminoplasty (myelopathy group). Body sway was assessed using stabilometry, wherein patients stood on a stabilometer with their eyes closed for 30 seconds. The Romberg ratio, outer peripheral area (OPA) with eyes closed (cm2), and total locus length per unit area (L/A) with eyes closed (/cm) were examined. Examinations were performed preoperatively (at baseline) and at 8 weeks postoperatively. Examination results of patients in the myelopathy group were compared with those of 17 healthy individuals (control group). Clinical symptoms were evaluated using the Japanese Orthopaedic Association scale score (JOA score) and the timed up and go (TUG) test.
In the myelopathy and control groups, the mean baseline Romberg ratio, OPA, and L/A were 2.3±1.2, 8.9±5.5 cm, and 14.2±5.3/cm and 1.4±1.0, 4.3±2.8 cm, and 23.7±10.1/cm, respectively. Eight weeks after laminoplasty, only L/A showed significant improvement from baseline in the myelopathy group (23.2±10.1 to 16.8±7.9; =0.03). The Romberg ratio and OPA showed improvement in the myelopathy group, but the changes were not statistically significant. JOA scores and TUG test results in this group significantly improved from baseline to 8 weeks after laminoplasty (12.7 to 13.4 and 10.8 to 8.0 seconds, respectively; both <0.05).
L/A is a useful parameter for measuring body sway to assess the recovery of body sway after laminoplasty.
前瞻性研究。
运用稳定测量法检查因脊髓型颈椎病接受颈椎椎板成形术患者的身体摆动变化情况。
尽管脊髓型颈椎病患者主诉身体摆动，但客观检查身体摆动的报告较少。
纳入2010年10月至2013年2月间接受脊髓型颈椎病治疗的患者。21例患者接受了颈椎椎板成形术（脊髓病组）。使用稳定测量法评估身体摆动，即患者闭眼站在稳定测量仪上30秒。检测闭眼时的罗姆伯格比率、外周面积（OPA，单位：平方厘米）以及单位面积轨迹总长度（L/A，单位：每平方厘米）。术前（基线时）和术后8周进行检测。将脊髓病组患者的检测结果与17名健康个体（对照组）的结果进行比较。使用日本骨科协会量表评分（JOA评分）和计时起立行走测试（TUG测试）评估临床症状。
脊髓病组和对照组的平均基线罗姆伯格比率、OPA和L/A分别为2.3±1.2、8.9±5.5平方厘米和14.2±5.3每平方厘米，以及1.4±1.0、4.3±2.8平方厘米和23.7±10.1每平方厘米。椎板成形术后8周，脊髓病组仅L/A较基线有显著改善（从23.2±10.1降至16.8±7.9；P = 0.03）。脊髓病组的罗姆伯格比率和OPA有所改善，但变化无统计学意义。该组的JOA评分和TUG测试结果从基线到椎板成形术后8周有显著改善（分别从12.7提高到13.4以及从10.8秒缩短到8.0秒；均P < 0.05）。
L/A是测量身体摆动以评估椎板成形术后身体摆动恢复情况的有用参数。
