Abstract
Objective: Establish between-day test-retest reliability metrics for 2-dimensional frontal plane projection angles (FPPAs) during the lateral step-down (LSD), single-limb squat (SLS), single-limb landing (SLL), and drop vertical jump (DVJ).
Design: Test-retest reliability study
Setting: University laboratory
Participants: 20 healthy adults (12 female, age = 23.60±1.93 years old, body mass index = 24.26±2.54 kg/m2) were tested on 2 separate occasions 7-14 days apart.
Main Outcome Measures: Intraclass correlation coefficients (ICC), standard errors of the measurement (SEM), and minimal detectable change (MDC) values across the LSD, SLS, SLL, and DVJ for the following body region variables: trunk, trunk on pelvis, pelvis, hip, thigh to vertical, knee, and shank to vertical.
Results: There was moderate-to-substantial between-day test-retest reliability for nearly all body regions across all tasks (ICC = 0.65-0.96). SEM values varied across body regions and tasks (0.9-3.5 degrees). MDCs were variable (2.3-9.8 degrees). Of the body regions, MDCs were largest for the knee and hip. By task, MDCs were lowest for the LSD.
Conclusions: This study identified between-day test-retest reliability metrics for 2-dimensional FPPAs across a variety of body regions during commonly assessed clinical tasks. These data allow clinicians and researchers to more confidently assess true change between assessments or over time.
