近年来，体重支持（BWS）系统得到应用，并在大多数步态训练系统中发挥了重要作用。传统的BWS系统通常采用绳滑轮机构，因此步态训练时产生的“钟摆效应”会引起受试者的不适。我们的假设是，在重量支撑系统下行走时，受试者横向和垂直方向的质心 (COM) 参数会发生变化。此外，所开发的新型 BWS 系统将减少行走过程中的“钟摆效应”，并与配重系统相比表现出增强的行为。我们的研究结果表明，在使用新的 BWS 和配重系统的情况下，步宽和中间方向和垂直方向的 COM 幅度明显小于正常行走情况。使用新的 BWS 时获得的 COM 振幅更接近正常步行情况，并且高于配重系统。
In recent years, body weight support (BWS) systems have been applied and have played an important role in most of the gait training systems. Conventional BWS systems commonly use the rope–pulley mechanism such that the “pendulum effect” generated during gait training would cause discomfort to the subject. Our hypothesis was that the center of mass (COM) parameters in the lateral and vertical directions of the subject during walking under a weight support system would be modified. Moreover, the novel BWS system that was developed would reduce the “pendulum effect” during walking and exhibit an enhanced behavior in comparison with the counter weight system. Our findings revealed that the step width and the COM amplitude in the mediolateral and vertical directions in the cases using the new BWS and counter weight systems were significantly smaller than those for the normal walking case. The COM amplitudes obtained when using the new BWS were closer to the normal walking case and higher than the counter weight system.
