Kinematic and EMG traces recorded in one adolescent (A) and one adult (B) with Down syndrome. Shadow areas highlight the excursion of the first flexion. BF1-F2 and KF1-F2 are normalized damping and stiffness coefficients for the first extension-flexion cycle after the first fall. The last two rows represent the full wave rectified EMG without (fourth row) and with (fifth row) TKEO signal condition.
