Inter-rater and Intra-rater reliability between experience and non-experienced examiners on 90-90 active knee extension test using Goniometer among healthy college students

Abstract

Purpose: Intra-rater reliability refers to the consistency of measurements demonstrated in similar assessment situation at two different times by the same examiner which also refers to test-retest. Interrater reliability test denotes the consistency of assessments performed by two different examiners. The objective of the study was to determine the inter-rater and intra-rater reliability between experienced and non-experienced physiotherapist on 90-90 active knee extension test using goniometer among healthy college students. Methodology: This study method is a reliability design in determining hamstring flexibility among 42 young healthy college students
