To determine whether the use of a low-cost virtual reality (VR) system used in conjunction with partial body weight-supported treadmill training (BWSTT) was feasible and effective in improving the walking and balance abilities of patients poststroke.
A before-after comparison of a single group with BWSTT intervention.
University research laboratory.
A convenience sample of 7 adults who were within 1 year poststroke and who had completed traditional rehabilitation but still exhibited gait deficits. Six participants completed the study.
Twelve treatment sessions of BWSTT with VR. The VR system generated a virtual environment that showed on a television screen in front of the treadmill to give participants the sensation of walking down a city street. A head-mounted position sensor provided postural feedback.
Functional Gait Assessment (FGA) score, Berg Balance Scale (BBS) score, and overground walking speed.
One subject dropped out of the study. All other participants made significant improvements in their ability to walk. FGA scores increased from mean of 13.8 to 18. BBS scores increased from mean of 43.8 to 48.8, although a ceiling effect was seen for this test. Overground walking speed increased from mean of .49m/s to .68m/s.
A low-cost VR system combined with BWSTT is feasible for improved gait and balance of patients poststroke.

确定使用低成本虚拟现实 (VR) 系统与部分减重支撑跑步机训练 (BWSTT) 结合使用是否可行，并且能否有效提高脑卒中后患者的行走和平衡能力。
一组具有 BWSTT 干预的前后比较。
大学研究实验室。
7 名成年人的便利样本，他们在脑卒中后 1 年内，并且仍表现出步态缺陷，但已完成传统康复。6 名参与者完成了研究。
12 次 BWSTT 与 VR 治疗。VR 系统生成了一个虚拟环境，在跑步机前的电视屏幕上显示，给参与者一种走在城市街道上的感觉。一个头戴式位置传感器提供姿势反馈。
功能性步态评估 (FGA) 评分、伯格平衡量表 (BBS) 评分和地面行走速度。
1 名受试者退出研究。所有其他参与者在行走能力方面都有显著提高。FGA 评分从平均 13.8 分增加到 18 分。BBS 评分从平均 43.8 分增加到 48.8 分，尽管该测试出现了上限效应。地面行走速度从平均.49m/s 增加到.68m/s。
低成本 VR 系统与 BWSTT 相结合，可改善脑卒中后患者的步态和平衡。
