Values are presented mean±standard error. Group 1: IC for 2 weeks and sham MT for 2 weeks after CR; Group 2: IC for 2 weeks and MT (25 μA for 2 weeks after CR; Group 3: IC for 2 weeks and MT (5,000 μAfor 2 weeks after CR; IC: immobilization by cast; MT: microcurrent therapy; CR: cast removal; CMAP: compound muscle action potential; GCM: gastrocnemius muscle; US: ultrasound; a), b), c: Any two means in the same row with different letters represent a significant difference at P<0.05, One Way ANOVA, post-hoc Tukey test.
