To test the usefulness of a novel performance test, the tally counter test (counter test), which uses a hand tally counter to objectively assess the severity of cervical myelopathy.
Eighty-three patients with compressive cervical myelopathy (mean age 64 ± 13 years) who were undergoing cervical laminoplasty and 280 healthy control subjects (aged 20-89 years) were tested. The subjects were instructed to push the button of a tally counter as many times as possible in 10 s. The average of the right- and left-sided values in each patient was used for analysis. In the patient group, counter test values were compared with Japanese Orthopaedic Association (JOA) and Japanese version of the 36-Item Short Form Health Survey scores preoperatively and 12 months postoperatively.
The average counter test value was significantly lower in patients with myelopathy than age- and gender-matched controls (32.9 ± 10.9 vs. 46.9 ± 8.5, P < 0.0001). The counter test value was significantly higher at 2 weeks postoperatively than preoperatively (P = 0.0014). Counter test values showed a moderate correlation with JOA scores and a weak to moderate correlation with SF-36 physical functioning, role functioning, and role-emotional scores both pre- and postoperatively. The intraclass correlation coefficient of counter test values was high both pre- and postoperatively.
The tally counter test is objective and quantitative assessment method for patients with cervical myelopathy. The test is simple, reliable, and capable of detecting small functional changes.
测试一种新型的计步器测试（计步器测试）的有效性，该测试使用手动计步器客观评估颈椎脊髓病的严重程度。
对 83 例接受颈椎板成形术的压迫性颈椎脊髓病患者（平均年龄 64±13 岁）和 280 名健康对照者（年龄 20-89 岁）进行测试。要求受试者在 10 秒内尽可能多地按下计步器按钮。每位患者的右侧和左侧值的平均值用于分析。在患者组中，术前和术后 12 个月，将计步器测试值与日本矫形协会（JOA）和日本版 36 项简短健康调查问卷评分进行比较。
脊髓病患者的平均计步器测试值明显低于年龄和性别匹配的对照组（32.9±10.9 与 46.9±8.5，P<0.0001）。术后 2 周的计步器测试值明显高于术前（P=0.0014）。计步器测试值与 JOA 评分呈中度相关，与术前和术后 SF-36 身体机能、角色功能和角色情感评分呈弱至中度相关。术前和术后计步器测试值的组内相关系数均较高。
计步器测试是一种客观、定量的颈椎脊髓病患者评估方法。该测试简单、可靠，能够检测到较小的功能变化。
