Why Should We Care?

• 97% of teens play games (in U.S.)– Younger gamers prefer consoles, online play

• 53% of all adults play games (in U.S.)– Older gamers prefer PCs, offline play

• Among gamers (in the U.S)– 25% under age 18– 49% between 18-49– 26% over age 50

• Numbers for Europe, Japan harder to findhttp://www.theesa.com/facts/pdfs/ESA_EF_2009.pdf

Burns

• “Lawsuit Claims Microsoft Xbox Sparked Fire That Killed Baby” (Information Week 2007)

• Xbox power-supply overheating– Device problem, not activity problem– Microsoft issued a recall but didn’t fix design

• PubMed says 8 hits, but mostly burn recovery, or burn-related training

Page 16: Games for Health 2010 - Game Related Illnesses and Injuries

16

Radio Interference

• BMJ 2008: “Wii seems safe with pacemakers” – Wii-mote uses Bluetooth (2.4 GHz RF)– Nintendo advises >9 inches– Pacemaker companies say minimum of 2-9 inches

• American Heart Association warns about headphones but not devices or Bluetooth transmissions– Xbox 360 uses proprietary 2.4 GHz RF– PS3 controllers use Bluetooth

Electromagnetic Interference

• PubMed: iPod pacemaker (5)– 2007 study says avoid < 2 inches– 2008 and 2009 study say no risk

• Headphones seem to be a bigger problem because of the magnets– Int. Heart J: “Electromagnetic interference

with a bipolar pacemaker by an induction heating rice cooker.”

Rashes and Sores

• The “How!” sign– Rubbing controller

against palm

Bruises and Bumps

• Wii manual

• Blogs and websites

• Microsoft (Natal) and Sony (Move) controllers

• “Impact” vests?!

Page 23: Games for Health 2010 - Game Related Illnesses and Injuries

23

Foot Injury

• New England Journal of Medicine “A radiograph showed a small fracture of the base of

the fifth metatarsal. … The fracture probably resulted from the pull of the peroneus brevis muscle during inversion of the ankle.”

• Response (HealthDay) “Robert Gotlin, director of the Sports Rehabilitation

department at Beth Israel Medical Center in New York City, concurred with Eley's sense that while the risk for injury due to Wii gaming is real, it is not a cause for alarm.”

2010

Eley, K. A Wii Fracture. N Engl J Med. 2010 Feb 4;362:473-474. (letter to the editor)

Fall Risk

Most references talk about Wii being used to improve balance and reduce fall risk

Page 25: Games for Health 2010 - Game Related Illnesses and Injuries

25

Eyestrain

• PubMed: eyestrain (759)• PubMed: video game eyestrain (5)

• 1991 Japanese study– Shorter viewing distance while gaming (vs. TV)– More complaints after gaming >120 min.– Games use more rapid eye motion (vs. VDT work)– Clinically, games and word processing are similar

Misawa T, Shigeta S, et al. [Effects of video games on visual function in children] Nippon Eiseigaku Zasshi. 1991 Feb;45(6):1029-34. (in Japanese)

Page 26: Games for Health 2010 - Game Related Illnesses and Injuries

Photosensitive Epilepsy

• Pokemon TV show 1997– Over-reported cases due to media coverage

• Primarily a childhood disorder

• 5.7% of teenage epilepsy in U.K. 1995

• PubMed: photosensitive epilepsy (1519)

Quirk J., Fish D., et al. Incidence of photosensitive epilepsy: a prospective national study. Electroencephalography and Clinical Neurophysiology. 1995;95(4):260-267

Motion Sickness

• Not a new problem– Flight simulators – Since 1950s (Army report)

• Causes?– Sensory conflict theory– Postural instability theory

• Solutions?– Adaptation– No same-day flying– 2%-3% cannot adapt

http://www.hqda.army.mil/ari/pdf/RR%201832.pdf

Page 28: Games for Health 2010 - Game Related Illnesses and Injuries

Physiological Stress

• Cortisol (“stress” hormone)– Increased blood pressure– Cardiovascular activity– Gastric secretion

• Music in games can increase stress

• Wii “Vitality Sensor”– Pulse oximeter– Games for relaxation

Hearing Loss

• Noise-induced hearing loss

• Affects ~10 millions Americans a year

• >85 dB over a period of time (8 hrs)

• Associated with firearm use (veterans)

• 12%-15% of all children

2010

Medical Addiction

• PubMed: video game addiction (71)• PubMed: gambling addiction (2715)• 2009 AMA ruling says not “addiction”• 2008 article in Int J Ment Health Addiction

“The evidence so far suggests that genuinely excessive players are likely to have other underlying problems, and/or have inadequate time management skills. Excessive video game playing is therefore likely to be a symptom and not the cause of their problem.”

Wood, R. Problems with the Concept of Video Game "Addiction": Some Case Study Examples. Int J Ment Health Addiction (2008) 6:169–178.

Page 31: Games for Health 2010 - Game Related Illnesses and Injuries

Addiction vs. Overuse

• AMA notes that “overuse” still problematic

• Treatment programs and support groups

Page 32: Games for Health 2010 - Game Related Illnesses and Injuries

32

Sleep Deprivation

• Teen sleep deprivation a “growing” issue– Studies & reports are growing– Often cite gaming and other technologies

• Self-reported “addicts” suffer more– ~13% self-report rate– Remember, 98% of kids play games– Sleep deprivation a side-effect of overuse

2010

Other Side-effects?

• Google: "carbon monoxide poisoning" "video games“ (30,200)

• Almost all hits refer to a single article “5 incidents in which video games were being

powered [during Hurricane Ike] accounted for 75% (15 of 20) of the pediatric poisonings.”

Fife, C., Smith, L., et al. Dying to Play Video Games: Carbon Monoxide Poisoning From Electrical Generators Used After Hurricane Ike. Pediatrics 2009;123;e1035-e1038.

Summary

• Growing media coverage

• Some scientific literature, but not much

• More people play games than exercise

• Games becoming more like exercise

• Most game injuries caused by overuse– The old complaint used to be inactivity– The emerging problem is overactivity
