Application of musculoskeletal ultrasound in quantitative assessment and rehabilitation of lower leg muscles in stroke patients.

Favorable outcomes were associated with greater tibialis anterior and medial gastrocnemius muscle architectural parameters ( P < 0.05).

The combined logistic model improved prediction (AUC = 0.801).

Hierarchical analysis demonstrated that adding MSUS parameters to baseline functional scores increased predictive performance (AUC from 0.721 to 0.833).
