Abstrakt: Introduction: Photogrammetry represents an advancement in the flexibility evaluation, and although it was highly explored for postural assessment, there is a scarcity of studies analyzing lower limb angular measurements using it. The purpose of this study is to verify the reliability of intrarater and interrarater photogrammetry in assessing lower limb flexibility.
Methods: This was a randomized cross-sectional observational study with test-retest design and a two-day interval. Thirty healthy, physically active adults were included. Three novice raters assessed the participants through flexibility tests of iliopsoas, hamstring, quadriceps and gastrocnemius on two occasions, and independently analyzed the captured images to establish reliability. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC) were calculated.
Results: Intrarater reliability was excellent for iliopsoas (ICC = 0.96; SEM = 1.4; MDC = 3.8), hamstring (ICC = 0.99; SEM = 1.1; MDC = 3.1), quadriceps (ICC = 0.99; SEM = 0.8; MDC = 2.3) and gastrocnemius (ICC = 0.98; SEM = 0.9; MDC = 2.5). Interrater reliability was excellent for iliopsoas (ICC = 0.94; SEM = 1.7; MDC = 4.6) and gastrocnemius (ICC = 0.91; SEM = 2.1; MDC = 5.8), but good for hamstring (ICC = 0.90; SEM = 2.8; MDC = 7.9) and quadriceps (ICC = 0.85; SEM = 3.0; MDC = 8.3).
Conclusions: The excellent intrarater and good to excellent interrater reliability suggest that photogrammetry assessment of lower limb flexibility by novice raters is reliable. However, clinicians should consider the higher threshold of range of motion change necessary to outweigh measurement error due to interrater variability.
