Reasons for these knowledge gaps from other rehabilitation studies to patients with iSCI or lack of clinical implementation are unclear, but may be due to adherence to traditional rehabilitation theories. One concern is that practicing only stepping tasks reduces attention towards hallmark physical impairments following iSCI, such as loss of strength or postural stability, which are considered primary determinants of decreased mobility. Only a few studies have addressed whether providing only structured stepping training can mitigate these impairments without their explicit practice, but not in the iSCI population. A related concern is that focused stepping training without significant attention towards impairments or gait quality may exaggerate altered movement strategies, which could be reinforced with repeated practice. However, there is little data to suggest "worsening" of abnormal gait patterns following high intensity training. Rather, recent findings suggest patients demonstrate more normal kinematics. If focused task specific (i.e., stepping) training is to be applied clinically, the investigators must delineate its contributions towards improving locomotor function, and their effects on underlying impairments and gait kinematics.
