由于最低水平的步态障碍（例如肌肉骨骼障碍、周围神经病和神经根病）或中间水平的障碍（例如偏瘫、截瘫和肌张力障碍）导致的身体节段的异常运动影响行走期间的重心（CG）的运动。CG的平移可以通过肌肉相对于地面所做的功（WExt）来研究。步态机制的有效性可以通过重力势能和动能之间的能量转移（恢复）来量化。在水平行走过程中，对最低和中等水平步态障碍的WExt和恢复进行了研究。最低程度步态障碍患者与正常受试者之间无统计学显著差异。然而，中度步态障碍患者的WExt增加，恢复下降高达20%。测量CG的机械能变化可能是病理步态力学的综合指标。(C)2000 Elsevier Science B.V.保留所有权利。
Abnormal movements of the body segments due to lowest level gait disorders such as musculoskeletal disorders, peripheral neuropathies and radiculopathies or middle-level disorders such as hemiplegia, paraplegia and dystonia influence the motion of the centre of gravity (CG) during walking. The translation of the CG can be studied by the work done by muscles (WExt) with respect to the ground. The efficacy of gait's mechanism can be quantified by the energy transferred between gravitational potential and kinetic energies (recovery). WExt and recovery were investigated in lowest and middle-level gait disorders during level walking. No statistical significant difference was observed between patients with lowest-level gait disorders and normal subjects. However, WExt was increased for the patients with middle-level gait disorders and recovery decreased up to 20%. The measurement of changes in mechanical energy of the CG might be a summary indicator for the mechanics of pathological gait. (C) 2000 Elsevier Science B.V. All rights reserved.
