复合感觉测试在慢性腰痛人群中的信度研究

Reliability of sensory test in individuals with chronic low back pain

目的:评估两点辨别测试(TPD)、点对点测试(PTP)和两点距离估算(TPE)三种测试在正常人和慢性腰痛人群(CLBP)中的重测信度和测试者间信度。方法:筛选30例正常人和30例CLBP患者,由两名物理治疗师分别对60例受试者进行TPD、PTP和TPE三种测试评估,测试者间测试间隔时间为10min,其中一人在24h后重复上述测试,通过组内相关系数(ICC)评估重测信度和测试者间信度。结果:正常组中,TPD、PTP和TPE三种测试左右两侧的重测信度(ICC:0.78—0.90)和测试者间信度(ICC:0.75—0.87)均良好。腰痛组中,TPD、PTP和TPE三种测试疼痛侧与非疼痛侧的重测信度(ICC:0.75—0.90)良好,测试者间信度(ICC:0.72—0.87)中等到良好。结论:三种评估方法在正常人和慢性腰痛人群中的信度可靠,足以在未来评估两种人群的触觉敏锐度。

Objective:To assess the intra-and inter-tester reliability of two-point discrimination(TPD),point-to-point test(PTP)and two-point estimation(TPE)in healthy subjects and subjects with chronic low back pain(CLBP)respectively.Method:Thirty healthy people and 30 patients were recruited with CLBP and divided into a healthy group and a CLBP group,equally.Subjects were assessed by two testers within the same day(10 min interval),and one of the testers repeated the assessment program 24 h later.The intraclass correlation coefficient(ICC)was used to assess the reliability.Result:In the healthy group,the intra-tester reliability of three measurements on both sides of L5 was good(ICC:0.78—0.90),while the inter-tester reliability of three measurements on both sides of L5 was good(ICC:0.75—0.87).In the CLBP group,the intra-tester reliability of three measurements on the pain and non-pain sides was good(ICC:0.75—0.90),while the inter-tester reliability of three measurements on the pain and nonpain sides was moderate to good(ICC:0.72—0.87).Conclusion:The reliability of the three assessment methods in healthy people and patients with CLBP is reliable enough to assess the tactile acuity of both groups in the future.
