Jaffe et al., 2004 [28]20 chronic stroke patients; mean age = 60.7 years; mean years after stroke = 3.8 Experimental  
VR-based treadmill training (stepping over virtual objects while walking on treadmill)
Control  
Stepping over real foam objects on a 10 m walkway
6 sessions of 60 min/session, 3x/week for 2 weeksGait velocity and stride length: walking test; balance: balance test; ability to step over obstacles: obstacle test; walking endurance: 6 min talk test. Baseline, end of treatment, and 2-week retentionGreater improvement in experimental group in gait velocity during the fast walk test ( ). Subjects in both groups improved in stride length, walking endurance, and obstacle clearance capacity.

Baseline, end of treatment Greater improvement in experimental group in the FAC and MMAS ( ). Also, the LI of the SMC area of the VR group increased significantly, compared to the control.
