Computed gastrocnemius muscle moment arm based on wrapping objects derived from 3D ultrasound: Exploring the impact of ankle position and predictability of anthropometrics.

The objective of this study was to evaluate the effectiveness of subject-specific wrapping objects (SS.WOs) derived from 3D ultrasound measurements in calculating the musculotendon moment arm, particularly the lateral gastrocnemius muscle moment arm at the knee (Gas.lat KMA).
