Fig. 1From: Visual biofeedback training reduces quantitative drugs index scores associated with fall riskScatterplot of the change in QDI scores for both the treadmill walking only participants (open squares) and treadmill gait training +VFB participants (open triangles), as a function of age. The horizontal line (score of zero), represents no change between the post- and pre- intervention QDI scores. The graph contains replicate change in QDI scores for several specific ages, in both treadmill walking only and treadmill gait training +VFB groups. These replicates may result in each icon representing more than a single responseBack to article page
