Speed, asymmetry and muscle coordination during walking Slow walking speed and asymmetric movement patterns are commonly observed in individuals with gait impairments and reflect an underlying alteration in muscle coordination patterns compared to healthy adults walking at self-selected speeds. Experimental and simulation studies have been used to investigate the effect of walking speed and asymmetry on kinematics, kinetics and energetics. Preliminary results and the implications for individuals with stroke and osteoarthritis will be discussed in this seminar.
