Fig. 3From: Fused ultrasound and electromyography-driven neuromuscular model to improve plantarflexion moment prediction across walking speedsSOL muscle thickness tracking results by using UltraTrack at different walking speeds on Participant Sub08. Each subplot represents the tracking results during the recorded 20 s experiments under each walking speed, and the red solid and blue dashed lines represent the results with and without key-frame correction, respectivelyBack to article page
