A series of pilot studies were conducted to examine the effects of partial body weight (PBW) ambulation in people with chronic stroke.
First, we compared gait characteristics during 3 modes of walking: level ground ambulation; level ground ambulation with PBW; and treadmill ambulation with PBW. Second, we examined the effects of repeated PBW treadmill training during level ground ambulation.
Improved symmetry in stance/swing times and sEMG activity of pre-tibialis and quadriceps muscle groups during PBW either over level ground or on the treadmill occurred in 10 chronic stroke subjects. Increased single limb support and decreased double limb support improved overall gait symmetry during level ground ambulation in 8 subjects following 6--8 weeks repeated PBW treadmill training. Tinetti Balance score also significantly improved. No changes in sEMG were observed.
These results suggest that PBW treadmill may help normalize gait and improve balance in the person with chronic stroke.
开展了一系列试点研究，以检验部分体重（PBW）步行对慢性中风患者的影响。
首先，我们比较了三种步行模式下的步态特征：平地行走；使用PBW的平地行走；以及使用PBW的跑步机行走。其次，我们研究了在平地行走期间重复进行PBW跑步机训练的效果。
10名慢性中风患者在使用PBW进行平地或跑步机行走时，其站立/摆动时间的对称性以及胫前肌和股四头肌肌群的表面肌电图（sEMG）活动均得到改善。在进行6至8周的重复PBW跑步机训练后，8名受试者在平地行走时单腿支撑增加、双腿支撑减少，从而改善了整体步态对称性。Tinetti平衡评分也显著提高。未观察到sEMG有变化。
这些结果表明，PBW跑步机可能有助于使慢性中风患者的步态正常化并改善其平衡能力。
