“… 23 , 24 Indeed, both observations of walking and virtual walking produce similar, and even higher, levels of cerebral activation compared to real walking. 25 , 26 These findings suggest that our cognitive training emphasizing virtual movement may activate the same neural systems involved in mobility. In turn, activation of cerebral structures involved in the walking may to the same degree also generate subliminal or even supraliminal muscle contractions/activation, which in turn may affect blood flow to the muscles.…”

We investigated the effects of bed rest (BR) immobilization, with and without computerized cognitive training with virtual spatial navigation task (CCT), on vascular endothelium on older subjects. The effects of 14-day BR immobilization in healthy older males (n=16) of ages 53–65 years on endothelial function were studied using EndoPAT®, a noninvasive and user-independent method. From the group of 16 older men, 8 randomly received CCT during the BR, using virtual navigation tasks in a virtual environment with joystick device. In all the cases, EndoPAT assessments were done at pre- and post-BR immobilization as well as following 28 days of ambulatory recovery. The EndoPAT index increased from 1.53±0.09 (mean ± standard error of the mean) at baseline to 1.61±0.16 following immobilization (P=0.62) in the group with CCT. The EndoPAT index decreased from 2.06±0.13 (mean ± standard error of the mean) at baseline to 1.70±0.09 at the last day of BR study, day 14 (BR14) (P=0.09) in the control group. Additionally, there were no statistically significant differences between BR14 and at 28 days of follow-up (rehabilitation program) (R28). Our results show a trend of immobilization in older persons affecting the vasoconstrictory endothelial response. As the control subjects had a greater increase in EndoPAT index after R28 (+0.018) compared to subjects who had cognitive training (+0.11) (calculated from the first day of BR study), it is possible that cognitive training during BR does not improve endothelial function but rather contributes to slowing down the impairment of endothelial function. Finally, our results also show that EndoPAT may be a useful noninvasive tool to assess the vascular reactivity.

“…At a comfortable walking speed, both walking rate and walking speed tended to increase after the intervention, and cadence increased significantly. In terms of the changes in gait after the intervention, experiencing the VR presentation brings about physiological changes in the cerebrum, which causes optical flow 4) and kinesthetic illusion induced by visual stimulation 2,3,9) . Given that the optic pathway is bilaterally symmetrical within the cerebrum, there may only be a little difference in the optic pathway depending on which hemisphere is damaged.…”

“…VR presentations offer a range of uses, as patients can move freely within the area covered by infrared beams emitted from four points while manipulating a special controller to engage in training, or simply use them to watch videos. The visual stimulation provided by these videos is believed to allow easier induction of physiological changes, such as kinesthetic illusion induced by visual stimulation 2,3) and optical flow 4) .…”

The objective of this study was to provide cerebral stroke patients with virtual reality videos of gait occurring at a faster speed than their actual measured gait speed and ascertain the effect on generating errors of gait. [Participants and Methods] The participants were 12 stroke patients. They were given a 2-minute virtual reality presentation of gait occurring at a speed faster than their actual measured comfortable walking speed. Immediately following the presentation, their 10-m walking speed was measured again to observe the immediate effect of the intervention, after which the time required to walk at maximum gait speed was measured. Stride length, cadence, and walking speed before and after the intervention were compared. In addition, heard an immersive feeling.[Results] At a comfortable walking speed, the cadence improved significantly post-intervention. Walking speed and stride length also tended to increase. At the maximum walking speed, there were no significant differences in any parameter. There was no problem with the immersive feeling. [Conclusion] After watching virtual reality videos of gait at a speed faster than the patients' actual gait speed, their walking speed tended to increase in comfortable walking. It was speculated that this technique could be applied to walking training, depending on the device.
