Summary
The standing ankle dorsiflexion screen (SADS) reliably measures ankle range of motion, offering a quick alternative for assessing limited dorsiflexion linked to injuries.
Area of Science:
- Biomechanics
- Sports Medicine
- Kinesiology
Background:
- Limited ankle dorsiflexion (DF) is a risk factor for lower extremity injuries.
- Traditional ankle DF measurements are time-consuming in athletic settings.
Purpose of the Study:
- To evaluate the reliability and discriminant validity of the novel standing ankle dorsiflexion screen (SADS).
Main Methods:
- A reliability and validity study involving 37 healthy subjects.
- Two measurement methods were used: a modified lunge with an inclinometer and the SADS.
- Intraclass correlation coefficients (ICC) and kappa coefficients assessed interrater reliability.
Main Results:
- The SADS demonstrated excellent interrater reliability (ICC=0.95) and high kappa values (0.61-0.81).
- High percent agreement (86-94%) was observed between raters.
- Significant differences in ankle DF ROM were found between SADS categories ('behind' vs. 'beyond').
Conclusions:
- The SADS exhibits excellent reliability and discriminant validity for assessing closed-chain ankle DF ROM.
- It serves as an efficient screening tool for identifying limited ankle dorsiflexion.
