Evaluation of the within- and between-day intra-tester and inter-tester reliability of positioning subjects into neutral and lordotic sitting postures

Purpose: To assess the reliability of postural positioning in two different sitting postures (SP), within- and between-days, as well as intra-tester and inter-tester. Methods: Twenty six individuals were facilitated into lordotic (LSP) and neutral (NSP) SP on two different days by four physiotherapi...

Description
Summary:Purpose: To assess the reliability of postural positioning in two different sitting postures (SP), within- and between-days, as well as intra-tester and inter-tester. Methods: Twenty six individuals were facilitated into lordotic (LSP) and neutral (NSP) SP on two different days by four physiotherapists, while kinematic data were collected. Intra-tester and inter-tester reliability were assessed using measures of relative reliability (intra-class correlation coefficients, ICC) and absolute reliability (standard error of measurement-SEM; minimal detectable change; mean difference; limits of agreement). Results: Substantial or almost perfect relative reliability (ICC >0.67), with very good absolute reliability (SEM
