Week 15

Question 1

Virtual reality is

Answer 1

Three dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment

Question 2

How did the Nintendo Wii improve people with parkinsons (research)

Answer 2

Improved sensorimotor performance

Increase stride length and gait speed

Reduction in motor impairment

Less rigidity and more flexibility of lower limbs

Greater functional independance

Question 3

What is CAREN system

Answer 3

Computer assisted rehabilitation environment

Question 4

What is CAREN

Answer 4

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

Question 5

What can CAREN system be used for

Answer 5

Parkinson disease

Stroke

Concussion

Older fallers

Amputees

Question 6

What were the effects of virtual reality training on gait biomechanics of post stroke people

Answer 6

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

Question 7

Did VR games improve mobility skills and balance in older adults

Answer 7

Positive clinical effects of VR games for balance and mobility improvements

Question 8

Why does VR improve gait and movement biomechanics in individuals with balance disorders or post injury

Answer 8

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

Question 9

What is EEG

Answer 9

Electroencephalogram

Small electrodes placed on scalp

Tracks and records brain wave patterns

Question 10

What is a Lokomat

Answer 10

Exoskeleton that helps power the limbs

Used in stroke and other rehab

Question 11

Did VR improve movement pattern in patients after ACL reconstruction

Answer 11

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

Question 12

Virtual reality summary

Answer 12

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

Question 13

Virtual reality is very expensive and relatively cost-prohibitive for most rehabilitation clinics, in any form

Answer 13

False

Question 14

The video from Neuroscience Research Australia used the Nintendo Wii as a form of rehabilitation for which condition

Answer 14

Stroke

Question 15

Research on using the Nintendo Wii for Parkinson’s rehabilitation found which gait variables were improved after Wii-based therapy

Answer 15

Stride length and walking velocity

Question 16

What is the CAREN system

Answer 16

An immersive virtual reality system that incorporates a treadmill, hydraulics, and motion capture for rehabilitation and biomechanics research

Question 17

Post-stroke, participants were able to generate greater power at which joint with virtual reality training, compared to the non-virtual reality training group

Answer 17

Ankle

Question 18

EEG research suggested that using virtual reality during rehabilitation may improve functional biomechanical outcomes compared to non-VR training because

Answer 18

VR training increases activity of brain areas associated with motor planning and learning

Question 19

Virtual reality training did not significantly improve biomechanics for patients recovering from an ACL reconstruction

Answer 19

False
