VR

definition of virtual reality

Computer generated environment drawing on three primary senses → primarily vision

Continuum of fimmersion from most to least

head mounted display (complete)→ cave→ glasses that render a 2d image 3d (semi)

what is immersion based on

the hardware

what is presence based on

Psychological experience, how a person feels

examples of serious games (non-custom systems for rehab)

Wii, kinect

key concepts of serious games

goal motivation, reward, challenge, narrative structure

findings of virtual reality post stroke from Cochrane review

favorable for UE rehab when >15 hrs

general protocol for custom VR system for UE

pre and post testing, Intervention at home 12 weeks, Instructed to perform at least

twenty minutes of practice every day, 4 simulations based on level of

motor control and goals, 2 in-person visits during the first month, transitioned to 5 remote support visits weeks 5-12

examples of lab based custom for rehab serious games

lan, IREX, play station II

effects of VR training on gait speed based on cochrane review

no statistically significant difference- consider lack of data

effects of VR training on balance based on cochrane review

significant improvement

range of intensity for activity that people post-stroke can achieve compared to able-bodies (METs)

reduced

how can active video games be helpful vs standard therapy

can promote increased repetitions, more engagement, similar intensity to walking→ consider patient preference

examples of interventions during telehealth

imagery for balance confidence, stair negotiation, LE strengthening, stationary cycling, non-custom video games (use whatever is available at home)

how are games selected when using VR

to target a specific motion or activity, patient preference

companies that superimpose activities from the real world into the virtual world

augmented reality
