Week 15 Flashcards
Virtual reality is
Three dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment
How did the Nintendo Wii improve people with parkinsons (research)
Improved sensorimotor performance
Increase stride length and gait speed
Reduction in motor impairment
Less rigidity and more flexibility of lower limbs
Greater functional independance
What is CAREN system
Computer assisted rehabilitation environment
What is CAREN
Multi sensory system for clinical analysis, rehab, evals and registration of the human balance system
Combines virtual reality and motion capture to provide immersive training environments and feedback
What can CAREN system be used for
Parkinson disease
Stroke
Concussion
Older fallers
Amputees
What were the effects of virtual reality training on gait biomechanics of post stroke people
Increase in ankle power generation at push off
Greater ankle ROM post training
Significant difference in Knee ROM on affected side during stance and swing - greater change in VR group
Did VR games improve mobility skills and balance in older adults
Positive clinical effects of VR games for balance and mobility improvements
Why does VR improve gait and movement biomechanics in individuals with balance disorders or post injury
EEG studies suggest that VR combined with robotic based rehab improves gait and balance
Use of VR may entrain several brain areas involved in motor planning and learning
Leading to enhanced motor performance
What is EEG
Electroencephalogram
Small electrodes placed on scalp
Tracks and records brain wave patterns
What is a Lokomat
Exoskeleton that helps power the limbs
Used in stroke and other rehab
Did VR improve movement pattern in patients after ACL reconstruction
Significnatly improved:
Knee flexion excursion
Vertical ground reaction force
Knee moment
Knee angle at peak VGRF
The VR distracts patients after ACLR from conscious motor control
Virtual reality summary
Virtual reality allows clinican to place patients in environments otherwise not possible
Is believe that VR during rehab may improve motor planning and learning
VR improves mechanical outcomes for specific rehabs
Virtual reality is very expensive and relatively cost-prohibitive for most rehabilitation clinics, in any form
False
The video from Neuroscience Research Australia used the Nintendo Wii as a form of rehabilitation for which condition
Stroke
Research on using the Nintendo Wii for Parkinson’s rehabilitation found which gait variables were improved after Wii-based therapy
Stride length and walking velocity
What is the CAREN system
An immersive virtual reality system that incorporates a treadmill, hydraulics, and motion capture for rehabilitation and biomechanics research
Post-stroke, participants were able to generate greater power at which joint with virtual reality training, compared to the non-virtual reality training group
Ankle
EEG research suggested that using virtual reality during rehabilitation may improve functional biomechanical outcomes compared to non-VR training because
VR training increases activity of brain areas associated with motor planning and learning
Virtual reality training did not significantly improve biomechanics for patients recovering from an ACL reconstruction
False
