To determine the intra-rater reliability of modified-modified Schober's test for measuring lumbar flexion and extension in patients of lumbar radiculopathy.
The case-control reliability study was conducted at the University of Lahore Teaching Hospital, Lahore, Pakistan, from March to September 2020, and comprised lumbar radiculopathy patients of either gender aged 35-60 years in group A and healthy controls in group B. Lumbar flexion and extension were measured by the same examiner on three different occasions. A non-stretching measuring tape was used in which the first two measurements were taken using the modified-modified Schober's test on the same day with a difference of 5 minutes, and the third measurement was taken three days later to assess reliability. To assess the test-retest reliability, intraclass correlation coefficient was calculated through two-way random analysis of variance. Standard error of measurement and minimal detectable change were also calculated. Data was analysed using SPSS 25.
Of the 40 subjects, 20(50%) were in group A with a mean age of 45.00±6.72 years, and 20(50%) were in group B with a mean age of 49.60±6.65 years. Overall, there were 16(40%) male and 24(60%) female subjects. Within-day lumbar flexion and extension measurements were highly reliable in controls (intraclass correlation coefficient 0.93 for flexion and 0.96 for extension) as well as in patients (intraclass correlation coefficient 0.94 for flexion and 0.95 for extension). The high values of intraclass correlation coefficient 0.91 for flexion and 0.94 for extension in the controls and 0.83 for flexion and 0.92 for extension in the patients showed high reliability also for between-days measurements.
The modified-modified Schober's test appeared to be a highly reliable technique for the measurement of lumbar flexion and extension in patients of lumbar radiculopathy as well as in healthy controls.
确定改良改良 Schober 试验测量腰椎前屈和后伸的组内信度,用于腰椎神经根病患者。
本病例对照可靠性研究于 2020 年 3 月至 9 月在巴基斯坦拉合尔大学教学医院进行,包括 A 组的男女腰椎神经根病患者(年龄 35-60 岁)和 B 组的健康对照者。由同一位检查者在三次不同时间测量腰椎前屈和后伸。使用非拉伸测量带,前两次测量在同一天使用改良改良 Schober 试验进行,间隔 5 分钟,第三次测量在三天后进行,以评估可靠性。为评估测试-再测试信度,通过双向随机方差分析计算组内相关系数。还计算了测量误差和最小可检测变化。使用 SPSS 25 进行数据分析。
40 名受试者中,20 名(50%)为 A 组,平均年龄为 45.00±6.72 岁,20 名(50%)为 B 组,平均年龄为 49.60±6.65 岁。总体上,有 16 名(40%)男性和 24 名(60%)女性受试者。在对照组中,当日的腰椎前屈和后伸测量高度可靠(前屈时组内相关系数为 0.93,后伸时组内相关系数为 0.96),患者组中也高度可靠(前屈时组内相关系数为 0.94,后伸时组内相关系数为 0.95)。对照组中 0.91 的高度组内相关系数用于前屈和 0.94 用于后伸,患者中 0.83 的高度组内相关系数用于前屈和 0.92 的高度组内相关系数用于后伸也表明了日间测量的高度可靠性。
改良改良 Schober 试验似乎是一种高度可靠的技术,可用于测量腰椎神经根病患者和健康对照者的腰椎前屈和后伸。
