AbstractThe purpose of this study was to explore health
benefits in somatosensory video games, Xbox 360 Kinect, on
institutionalized older adults with wheelchairs. A total of 53
participants were recruited and divided into an experimental
group (n = 22, 78.55 6.70 years old) and a control group (n =
31, 79.97 7.00 years old). The experimental group
voluntarily agreed to complete Xbox 360 Kinect trainings three
times per week, for 30 minute each session. The Vienna Test
System and the Soda Pop test were used to measure the simple
reaction and the eye-hand coordination of their visual
performance skills. A Mann-Whitney nonparametric test for
two independent samples was used to evaluate training effects.
Results showed that the interventions significantly improved
their visual performance skills and the elderly in the
experimental group improved significantly on the reaction test
(p< 0.001) and eye-hand coordination (p< 0.001). The study
concluded that Xbox 360 Kinect is a potential tool to improve
visual performance skills for the institutionalized elderly with
wheelchairs.

I. INTRODUCTION
With the trends of global aging, medical advances andlongevity, the quality of life and health care for older adultshas been dramatically noticed as one of the most significant
global issues. Aging mechanism decreases attention abilityand increases the risk of all [1]. From Physio-psychologicalperspective, the loss of brain tissue in aging process makesthe degeneration of cognition and may cause a variety ofillnesses (e.g., dementia), which negatively impact on theirdaily living skills and independent functions. Moreover, italso increases the national and individual expenses of long-term cares and medical costs economically [2] [3].
Although aging is an irreversible trend, current studiesfound that appropriate training programs may have
preventive benefits on promoting cognitive abilities andalleviating the degeneration of aging brains [4-10]. Physicalexercises and sport participations are commonly used topromote their health and maintain their brain and bodyfunction. For example, the Jensens study pointed out thatphysical activities and body movements can create positivevalues on promoting cognitive abilities [11]. In addition tophysical activities, recent studies stated that challenges anddifficulties in computer games are also able to active nervefunctions effectively [12]. Therefore, somatosensory videogames that combine computer games and physical activitiesmay be an innovation of providing alternative leisureopportunities for older adults.
Traditional video games that reply on joysticks or relatedcontrollers to receive players feedback and signals havebeen criticized as harmful products to health because theyare contributions of a sedentary lifestyle. However, with theadvances of technology, somatosensory video games werereleased and made the revolution of video games happened.Compared with traditional video games, somatosensoryvideo games abandon traditional joystick-like controllers butsense users gestures and body movements to interact withthe video games. Originated from pilots training programs,virtual-reality interaction technology began to been used asan entertainment since 1980s but Nintendo Wii primaryleaded the new generation in the video game industry in2006. The Wii video games have transformed into health
toys and have been endorsed by the department of Health inthe U.K. [13]. In 2010, Microsoft released Xbox 360 andSony also published Play Station Eye to join thesomatosensory video game markets.
Institutionalized older adults with wheelchairs who havehistories in stroke, fall and other accidental injuries alwayshave very limited mobility and sedentary lifestyles. Withrelatively fragile body conditions, those older adults need tohave physical/leisure activities that are able to promote theirhealth and prevent the negative impacts of aging anddisabilities. According to previous studies, digital games

have significant benefits on cognition improvement for olderadults because the sounds and lights of digital games thatemploy figures, voices, charts and visual stimulations tointeract with users can facilitate a variety of activities toalleviate the degeneration of the brain, to promote visualperformance skills and to improve emotional well-being[14][15]. Among all kinds of somatosensory video games,
Xbox 360 Kinect that does not need to hold any remotecontrollers is friendly for the elderly with wheelchairs.Therefore, the purpose of this study is to use this video gameon this population and to understand if it can enhance theirvisual performance skills.
II. R ESEARCH METHODOLOGY
A. Inclusion and Exclusion Criteria
The study was conducted at a nursing home which have335 residents in Changhua city, Taiwan. In the nursinghome, the study was advertised as training sessions for aSomatosensory Video Games in 2011. Oral introductionsand video demonstration with PowerPoint presentation were
provided during 1-week recruitment. In order to perform inthis game, participants were required to have verbalcommunication ability and basic physical functions toparticipate and approved by head nurses who knows theirhealth conditions.
B. Participants
In order to respect personal rights in making decisions oftheir own daily life schedules, non-random purposivesampling were utilized in this study to comply withInstitutional Review Board (IRB) regulation. A total of 53participants were recruited in this study. All institutionalizedolder adults with wheelchairs participated in the study werepre-approved by the medical/managing staff and signedinformed consent forms approved by the human subjects
committee at the Taipei Physical College (ApprovalReference No. 20110023, 8/23/2011) before participating inthe study.
C. SVG programs
A quasi-experimental design was used in this study.Experimental group voluntarily agreed to complete SVGtrainings three times per week, for 30 minute each sessionwhich included 5-minute warm up, 20-minute interactivegaming, and 5-minute cool down. Control group did notreceive any additional training but maintained regular dailyschedules and programs that were provided by the nursinghome. In the study, Xbox-360 Kinect was selected to bethe interventional modality. Mouse mayhem, follow the
arrow and matchmaker are three games which areappropriate to older adults with wheelchair inDr.Kawashima's Body and Brain Exercises and wereselected by the investigators who have long termprofessional working experiences the population. Table Ishowed the training progress notes in this study.

3) Mouse mayhem (Fig. 3) Total time of the game isone minute. The task in the game is to touch mice that
pop out from four different pines which are located at four
different corners on the screen. There are three kinds of
mice in the game. Regular green and gold mice are allowed
to touch and contribute to get points. Then, gold mice with
hedgehog hair shall be avoid to touch or points would be
deducted.

D. Measurement
In order to understand their improvement of visualperformance skills, Vienna Test System and computersoftware, S9 (Simple reaction-yellow, measurement ofreaction time only), are used in this study. In addition, eye-hand coordination was tested by using Soda Pop test.
1) Reactions: Vienna Test System (Simple reaction-
yellow, measurement of reaction time only)a) Testing time:3 minutes
b) Reliability The Cronbachs Alpha of the recreationtime is 0.963 [16].
2) Eye-hand coordination:Soda Pop test three soda pop
cans (355ml) are placed in every other circle (8.26cm)
starting from the side of the hand being tested. When the test
began, participants were asked to use their dominant hands to
grasp the first can and turn upside down into the adjacent
circle No.2 within the drawn line and No. 3 can to the No. 4
circle and No. 5 to the No.6 circle. The participant then
returns to the first can turned, replaces it in the original
position and proceeds with the other two cans. This whole
process is repeated twice [17]. Every participants wasrequested to complete the test twice and the higher scores
were used for the data analysisFig. 4.

E. Data Collection and Analysis
SPSS 18.0 was used to analyze the data. A Mann-Whitney nonparametric test for two independent sampleswas used to evaluate training differences in the experimentaland control groups for changes in reactions and eye-handsCoordination.
III. R ESULTS
The data set of 19 females and 3 males in theexperimental group and 18 females and 13 males in thecontrol group participated in this study. In the post-testperiod, 4 participants rejected to complete the test due to thebody discomfort and 1 participant only completed eye-handcoordination test and could not complete the reaction time
test due to the eye discomfort in control group. Accordingto the results of statistics, except the gender, there are nosignificant differences in their age, body weight and Mini-Mental Status Examination (MMSE) between the groups.Table II shows the demographic information of theparticipants.

IV. DISCUSSION
According to the findings, one-month Xbox 360 Kinectvideo game training (three times per week, for 30 minuteeach session) can successfully improved visual performanceskills (recreation time and eye-hand coordination) oninstitutionalized older adults with wheelchair.
Because aging process leads the degradation of thenervous system which will make the central nervous systemconduction have lower accuracy and the endocrine/nervoussystem become weakened, the reaction time of older adultstend to getting slow [19]. In addition, a variety of age-related illnesses also speed up the degradation process [20].However, reaction time plays an important key onmaintaining their activities of daily living (ADL). Forexample, the reaction time can help the elderly to interact
with daily living and help to solve sudden emergencies, suchas falls. In this study, the differences between the groupswere 106.45 ms in the pretest but have bigger difference (p
