Those who participate in sports or other physical activity
know that after a workout could come with some physiological discomfort. Such a
concept could be entering the realm of videogames, in a new condition dubbed “wiiitis.”
Michael P. Nett, Mark S. Collins and John W. Sperling of Mayo
Clinic have a journal
article titled “Magnetic resonance imaging of acute ‘wiiitis’ of the upper
extremity” published in the May edition of Skeletal
Radiology.
“We present the first reported case of acute ‘wiiitis’
documented clinically and by imaging, of the upper extremity, caused by
prolonged participation in a physically interactive virtual video-game,” read
the article’s abstract.
The article presented the case of a 22-year old male who
reported shoulder soreness after playing Wii Sports Bowling. From the abstract,
“Unenhanced magnetic resonance imaging (MRI) demonstrated marked T2-weighted
signal abnormality within several muscles of the shoulder and upper arm,
without evidence of macroscopic partial- or full-thickness tearing of the
muscle or of intramuscular hematoma.”
The diagnosis made by the doctors differed in several ways
from a person who experienced discomfort after playing a real-world game of
bowling. The journal article explained, quoted by GameCritics,
“[L]ittle resistance is offered by the light 200 g handheld controller to the
aggressive maneuvers made by the participant, which may lead to awkward
deceleration forces being applied to the upper extremity ... It is likely that,
during the deceleration phase of swinging the Wii controller, there is
significant eccentric loading on the participant’s muscle groups, causing the
ultrastructural damage, as demonstrated in this case.”
Nintendo has already remedied various
safety concerns with its introduction of Wii Remote additions such as
improved wrist
straps and rubber
jackets. While it’s unlikely that Nintendo will introduce added weights to
its controllers, don’t be surprised to see stretching instructions and new
disclaimers at the beginning of every game.
