Introduction

Wii Fit Intervention

• Purpose of the Wii Fit is to improve balance,
  strength, flexibility, fitness, and general
  well-being (Nitz, Kuys, Isles, Fu, 2009)
  
  
• Improves balance in persons compromised by stroke
  (Brown, Sugarman, Burstin, 2009 Deutsch,
  Robbins, Morrison, Bowlby, 2009)

An Approach to Improving Balance using a Virtual
Reality Intervention

• 9 sessions, 2 sessions/week

5
Purpose Statement

• To investigate the effect of 9 sessions of Wii
  Fit Balance training on static and dynamic
  balance of three boys with DCD aged 9-11 years.

Data Analysis
Pre- and post-intervention
Intervention measures measures
AMTI force plate protocol MABC Single subject design
Sway area AP sway ML sway path length possible anterior sway (PAS) possible posterior sway (PPS) - Total balance score (TBS) Scoring 2 or 3 stars (depending on game) for 3/5 trials 2 sessions in a row continue playing the same games
9
ResultsSingle Subject

• Participant 3 performing Soccer Header and
  Penguin Slide

10
Force plate Participant 3
Post-intervention balance space task
Pre-intervention balance space task
11
PAS PPS for dynamic balance

• Post-intervention increases in sway were measured
  with percent gains in balance space task
• Anterior sway 8.43
• Posterior sway 262

12
Discussion

• Wii Fit Balance Training
• Increased level, trend, and implied reaction and
  movement time
  
  
• Force Plate
• Increased sway in static balance tasks ?
  increased tolerance of sway
  
  
• Largest gain ? participant 1 (262) in posterior
  sway

13
MABC
Participant Pre-intervention TBS Post-intervention TBS
1 lt5 gt15
2 gt15 gt15
3 5 lt5

• Participant 3 made highest level of improvement
  with the Wii Fit, but obtained a worse TBS score
  post-intervention
• Suggests that the Wii Fit is more of a
  motivational tool than the static and dynamic
  balance tests of the MABC

14
Conclusion

• Motivator to practice balance games to
  
• React more quickly,
  
• Develop balance and problem-solving strategies
  
• Participants 2 and 3 were so engaged they
  purchased a Wii Fit
  
  
• Potential for balance training
  
• More research needed
