Fig. 1. Comparison of ΔO2 rate between experimental and control groups. (A) Difference in post-treatment to pre- treatment states (Δ) in the O2 rate (mL/kg·min) after treadmill training had no significant differences in the parameter during treadmill walking between experimental and control groups. (B) The experimental group did not show a significant improvement in the ΔO2 rate during overground walking.
