体重支持（BWS）系统已经显示出作为神经损伤个体康复工具的前景。本文综述了基于实验的步态控制系统的研究进展，目的是：(1)研究体重卸载对步态特征的影响；(2)研究在跑步机和地上行走时，BWU对步态特征的影响是否存在差异；(3)研究调节BWU对步态特征的影响是否小于未调节BWU。通过Pubmed、Scopus、Web of Science、b谷歌Scholar等搜索引擎进行系统的文献检索。统计分析量化BWU对步态参数的影响。54项健康和神经受损个体在BWS系统中行走的实验研究被纳入，其中32项被用于统计分析。文献分类使用三个区别：(1)跑步机或地上行走；(2)主体的类型；(3)卸荷力的性质。只有27%的研究是基于神经受损的受试者；考虑到他们是BWS系统的主要用户组，这个数字很低。研究包括5%至100%的BWU条件，其中30%和50% BWU条件的研究最为广泛。参与者的人数从1人到28人不等，平均为12人。结果表明，由于BWU水平的增加，关节力矩、肌肉活动、行走能量消耗和地面反作用力（GRF）与步态时空和关节运动学参数相比有较大的降低。BWU对运动学和时空步态参数的影响似乎仅限于卸载30%。5种步态特征在地面和跑步机上行走时表现出不同的行为响应。其余21种步态特征在地上和跑步机上行走时表现出相似的行为，但变化幅度不同。与未调制卸载相比，调制卸载力与0%状态的差异较小。这篇综述表明，BWU影响所有步态特征，尽管在运动学、时空和动力学特征之间存在重要差异。BWU对步态动力学特性的影响大于对时空参数和运动学特性的影响。结果表明，跑步机和地上步行可以以不同的方式改变BWU的影响。我们的研究结果表明，在BWU水平为30%及以下的情况下，特定任务的步态训练可能是可以实现的。本文的在线版本（10.1186/s12984-018-0380-0）包含补充材料，仅供授权用户使用。
Body weight support (BWS) systems have shown promise as rehabilitation tools for neurologically impaired individuals. This paper reviews the experiment-based research on BWS systems with the aim: (1) To investigate the influence of body weight unloading (BWU) on gait characteristics; (2) To study whether the effects of BWS differ between treadmill and overground walking and (3) To investigate if modulated BWU influences gait characteristics less than unmodulated BWU. A systematic literature search was conducted in the following search engines: Pubmed, Scopus, Web of Science and Google Scholar. Statistical analysis was used to quantify the effects of BWU on gait parameters. 54 studies of experiments with healthy and neurologically impaired individuals walking in a BWS system were included and 32 of these were used for the statistical analysis. Literature was classified using three distinctions: (1) treadmill or overground walking; (2) the type of subjects and (3) the nature of unloading force. Only 27% studies were based on neurologically impaired subjects; a low number considering that they are the primary user group for BWS systems. The studies included BWU from 5% to 100% and the 30% and 50% BWU conditions were the most widely studied. The number of participants varied from 1 to 28, with an average of 12. It was seen that due to the increase in BWU level, joint moments, muscle activity, energy cost of walking and ground reaction forces (GRF) showed higher reduction compared to gait spatio-temporal and joint kinematic parameters. The influence of BWU on kinematic and spatio-temporal gait parameters appeared to be limited up to 30% unloading. 5 gait characteristics presented different behavior in response to BWU for overground and treadmill walking. Remaining 21 gait characteristics showed similar behavior but different magnitude of change for overground and treadmill walking. Modulated unloading force generally led to less difference from the 0% condition than unmodulated unloading. This review has shown that BWU influences all gait characteristics, albeit with important differences between the kinematic, spatio-temporal and kinetic characteristics. BWU showed stronger influence on the kinetic characteristics of gait than on the spatio-temporal parameters and the kinematic characteristics. It was ascertained that treadmill and overground walking can alter the effects of BWU in a different manner. Our results indicate that task-specific gait training is likely to be achievable at a BWU level of 30% and below.
