Abstract 
Background 
Early rehabilitation in the intensive care unit (ICU) improves patients' physical function. Despite reports of using commercially available interactive video game systems for rehabilitation, there are few data evaluating feasibility and safety as part of routine in-patient rehabilitation, particularly in the ICU.

Methods
We conducted an observational study from September 1, 2009, to August 31, 2010, of adults admitted to a 16-bed medical ICU receiving video games as part of routine physical therapy (PT), evaluating use and indications and occurrence of 14 prospectively monitored safety events.

Results 
Of 410 patients receiving PT in the medical ICU, 22 (5% of all patients; male, 64%; median age, 52 years) had 42 PT treatments with video games (median [interquartile range] per patient, 1.0 [1.0-2.0]). Main indications for video game therapy included balance (52%) and endurance (45%), and the most common activities included boxing (38%), bowling (24%), and balance board (21%). Of 42 treatments, 69% occurred while standing and 45% while mechanically ventilated. During 35 hours of PT treatment, 0 safety events occurred (95% upper confidence limit for safety event rate, 8.4%).

Conclusions 
Novel use of interactive video games as part of routine PT in critically ill patients is feasible and appears safe in our case series. Video game therapy may complement existing rehabilitation techniques for ICU patients.

Objective 
To determine the relative effect of interactive digital exercise that features player movement (ie, exergames) on energy expenditure among children of various body mass indexes (BMIs; calculated as weight in kilograms divided by height in meters squared).

Design Comparison study.
Setting GoKids Boston, a youth fitness research and training center located at University of Massachusetts, Boston.

Participants 
Thirty-nine boys and girls (mean [SD] age, 11.5 [2.0] years) recruited from local schools and after-school programs.

Main Exposure
Six forms of exergaming as well as treadmill walking.

Main Outcome Measures 
In addition to treadmill walking at 3 miles per hour (to convert miles to kilometers, multiply by 1.6), energy expenditure of the following exergames were examined: Dance Dance Revolution, LightSpace (Bug Invasion), Nintendo Wii (Boxing), Cybex Trazer (Goalie Wars), Sportwall, and Xavix (J-Mat). Energy expenditure was measured using the CosMed K4B2 portable metabolic cart.

Results
All forms of interactive gaming evaluated in our study increased energy expenditure above rest, with no between-group differences among normal (BMI < 85th percentile) and "at-risk" or overweight (BMI 85th percentile) children (P .05). Walking at 3 miles per hour resulted in a mean (SD) metabolic equivalent task value of 4.9 (0.7), whereas the intensity of exergaming resulted in mean (SD) metabolic equivalent task values of 4.2 (1.6) for Wii, 5.4 (1.8) for Dance Dance Revolution, 6.4 (1.6) for LightSpace, 7.0 (1.8) for Xavix, 5.9 (1.5) for Cybex Trazer, and 7.1 (1.7) for Sportwall. Enjoyment of the games was generally high but was highest for children with BMIs in the highest percentiles.

Conclusion 
All games used in our study elevated energy expenditure to moderate or vigorous intensity. Exergaming has the potential to increase physical activity and have a favorable influence on energy balance, and may be a viable alternative to traditional fitness activities for children of various BMI levels.

Abstract 
The purpose of this study was to examine changes in physical activity and fitness variables in members of 8 volunteer families after 3 months of home use of the Wii Fit(TM) interactive video game. Pre and postintervention measurements were obtained from 21 subjects relative to physical activity (5 days of accelerometry), aerobic fitness (graded treadmill test), muscular fitness (push-ups), flexibility (sit-and-reach test), balance (composite equilibrium score), and body composition (body mass index and % body fat). Use characteristics of the Wii Fit(TM) device were also determined. A series of 2 (age group) x 2 (time) repeated measures analyses of variance were conducted to assess changes over time and between adults and children. Three months of home Wii Fit(TM) use revealed no significant age group x time interactions or main effects of group or time for daily physical activity, muscular fitness, flexibility, balance, or body composition. An age group x time interaction (p = 0.04) was observed in peak [latin capital V with dot above]O2 (ml[middle dot]kg-1[middle dot]min-1) with children displaying a significant (p = 0.03) increase after 3 months of Wii Fit(TM) use, whereas adults showed no significant (p = 0.50) change. Daily Wii Fit(TM) use per household declined by 82% (p < 0.01) from 21.5 +/- 9.0 min[middle dot]d-1 during the first 6 weeks to 3.9 +/- 4.0 min[middle dot]d-1 during the second 6 weeks. Most measures of health-related fitness in this exploratory study remained unchanged after 3 months of home use of the popular Wii Fit(TM) whole-body movement interactive video game. Modest daily Wii Fit(TM) use may have provided insufficient stimulus for fitness changes.

METs in Adults While Playing Active Video Games: A Metabolic Chamber Study

Medicine & Science in Sports & Exercise: June 2010 - Volume 42 - Issue 6 - pp 1149-1153 MIYACHI, MOTOHIKO; YAMAMOTO, KENTA; OHKAWARA, KAZUNORI; TANAKA, SHIGEHO +/- Click for more/less

Abstract Purpose: Active video game systems controlled through arm gestures and motions (Nintendo Wii Sports) and video games controlled through force plate (Wii Fit Plus) are becoming increasingly popular. This study was performed to determine the energy expenditure (EE) during Wii Fit Plus and Wii Sports game activities. Methods: Twelve adult men and women performed all the activities of Wii Sports (five activities: golf, bowling, tennis, baseball, and boxing) and Wii Fit Plus (63 activities classified as yoga, resistance, balance, and aerobic exercises). Each activity was continued for at least 8 min to obtain a steady-state EE. Because EE was assessed in an open-circuit indirect metabolic chamber consisting of an airtight room (20,000 or 15,000 L), subjects were freed of apparatus to collect expired gas while playing the games. MET value was calculated from resting EE and steady-state EE during activity. Results: The mean MET values of all 68 activities were distributed over a wide range from 1.3 METs (Lotus Focus) to 5.6 METs (single-arm stand). The mean MET values in yoga, balance, resistance, and aerobic exercise of Wii Fit Plus and Wii Sports were 2.1, 2.0, 3.2, 3.4, and 3.0 METs, respectively. Forty-six activities (67%) were classified as light intensity (<3 METs), and 22 activities (33%) were classified as moderate intensity (3.0-6.0 METs). There were no vigorous-intensity activities (>6.0 METs). Conclusions: Time spent playing one-third of the activities supplied by motion- and gesture-controlled video games can count toward the daily amount of exercise required according to the guidelines provided by the American College of Sports Medicine and the American Heart Association, which focus on 30 min of moderate-intensity daily physical activity 5 d·wk−1.

Abstract:

Objective: The aim of this preliminary study was to determine the effectiveness of the Nintendo Wii Fit as an occupation to promote weight loss in undergraduate students.

Participants: Five first-year female students living on campus at a northeastern university in the United States were recruited to participate in this study.

Method: An A-B single subject design was created where participants were separated into three groups: a typical activity group and two Wii conditions (Wii Fit individually and Wii Fit with another participant). In all conditions, participants recorded their daily food intake and daily number of steps using a pedometer. Body mass index (BMI) and weight were recorded at baseline, at 6 weeks and at 12 weeks (the conclusion of the intervention). At baseline and 12 weeks, motivation and activity level were measured.

Results: There was a significant change in BMI, weight and motivation for participants in the singles group.

Conclusion: Although the sample size was very small, the results of this preliminary study suggest that the Wii Fit should be considered by occupational therapists as a potential occupation of weight control in undergraduate students when performed individually.

ABSTRACT:

BACKGROUND:

Stroke is one of the leading causes of long-term disability in modern western countries. Stroke survivors often have functional limitations which might lead to a vicious circle of reduced physical activity, deconditioning and further physical deterioration. Current evidence suggests that routine moderate- or vigorous-intensity physical activity is essential for maintenance and improvement of health among stroke survivors. Nevertheless, long-term participation in physical activities is low among people with disabilities. Active video games, such as Nintendo Wii Sports, might maintain interest and improve long-term participation in physical activities; however, the intensity of physical activity among chronic stroke patients while playing Wii Sports is unknown. We investigated the energy expenditure of chronic stroke patients while playing Wii Sports tennis and boxing.

METHODS:

Ten chronic (≥ 6 months) stroke patients comprising a convenience sample, who were able to walk independently on level ground, were recruited from a rehabilitation centre. They were instructed to play Wii Sports tennis and boxing in random order for 15 minutes each, with a 10-minute break between games. A portable gas analyzer was used to measure oxygen uptake (VO2) during sitting and during Wii Sports game play. Energy expenditure was expressed in metabolic equivalents (METs), calculated as VO2 during Wii Sports divided by VO2 during sitting. We classified physical activity as moderate (3-6 METs) or vigorous (> 6 METs) according to the American College of Sports Medicine and the American Heart Association Guidelines.

RESULTS:

Among the 10 chronic stroke patients, 3 were unable to play tennis because they had problems with timing of hitting the ball, and 2 were excluded from the boxing group because of a technical problem with the portable gas analyzer. The mean (± SD) energy expenditure during Wii Sports game play was 3.7 (± 0.6) METs for tennis and 4.1 (± 0.7) METs for boxing. All 8 participants who played boxing and 6 of the 7 who played tennis attained energy expenditures > 3 METs.

CONCLUSIONS:

With the exception of one patient in the tennis group, chronic stroke patients played Wii Sports tennis and boxing at moderate-intensity, sufficient for maintaining and improving health in this population.

Abstract

Fatigue and physical deconditioning are common, difficult to treat conditions among patients with systemic lupus erythematosus (SLE). The aim of this pilot study was to evaluate the effectiveness of a home-based exercise program using the Wii Fit system in patients with SLE. Fifteen sedentary African American women with SLE experiencing moderate to severe fatigue participated in a home exercise program using the Wii Fit 3 days a week for 30 minutes each for 10 weeks. A one-group pretest-post test design was used to evaluate the effectiveness of this program. Primary outcome measure was severity of fatigue. Secondary outcome measures were body weight, waist circumference, fatigue-related symptoms of distress, activity level, and physical fitness. At the completion of the 10-week Wii Fit exercise program, participants perceived fatigue severity as measured by the Fatigue Severity Scale to be significantly decreased (p= 0.002), and body weight and waist circumference were significantly reduced (pp= 0.01). In addition, anxiety level, as measured by Hospital Anxiety and Depression Scale, and overall intensity of total pain experience, as measured by Short-form of the McGill Pain Questionnaire, were also significantly reduced (p < 0.05). Findings provide preliminary evidence that the Wii Fit motivates this population to exercise, which leads to alleviation of fatigue and reduced body weight, waist circumference, anxiety level, and overall intensity of total pain experience.

Abstract

-The Wii Fit™ is a form of interactive gaming designed to elicit health and fitness benefits to replace sedentary gaming.
This study was designed to determine the effectiveness of Wii Fit™ fitness games. The purpose of the study was to determine the %&OV0312;O2max and energy expenditure from different Wii Fit™ games at different levels including the step and hula games. Eight healthy young women completed a preliminary trial to determine &OV0312;O2max and later played the Wii Fit™ during 2 separate counterbalanced trials. During each session, subjects played levels of Wii Fit™ games for 10 minutes each level. One session involved beginning and intermediate hula, and the other session involved beginning and intermediate steps. The &OV0312;O2 was measured continuously via metabolic cart, and rating of perceived exertion (RPE) was assessed at the end of each game level. The lowest %&OV0312;O2max, kcal·min, and RPE occurred during the beginning step game and the highest values occurred during the intermediate hula game. Respiratory exchange ratio was significantly higher in the intermediate hula than beginning hula game but was not significantly different between step game levels. The intermediate hula and step games produced the greatest energy expenditure with an equivalent effect of a walking speed of >5.63 km·h (>3.5 miles·h). This is the first study to determine the percentage of &OV0312;O2max and caloric expenditure elicited by different Wii Fit™ video games at different game levels in adults. Findings suggest that the Wii Fit™ can be used as an effective activity for promoting physical health in this population.

Abstract
Issue addressed: Enhancing opportunities for all older people to be physically and mentally active is an imperative in our ageing society. Lessons learned from the use of the Nintendo Wii within Queensland agedcare and disability services were assembled through eliciting staff perceptions regarding the usefulness of Wii technology within their centres.

Methods: Telephone interviews were conducted with direct care staff in 53 centres that had been using the Wii technology for at least three months. Content analysis of interview data identified the major response patterns raised by staff.

Results: Staff noted that Wii activities were easy to master for more able clients and that there was minimal risk to clients. Staff reported that these activities provided health promoting physical benefits (mobility, range of motion, dexterity, coordination, distraction from pain) and psychosocial gains (social engagement, self-esteem, mastery, ability to pacify challenging behaviours) and were a useful adjunct to other care practices within these aged-care and disabilities services.

Conclusions: Staff believed that Wii activities provided purposeful and meaningful opportunities to promote wellbeing for aged and disabled clients within an aged-care and disability service. However, Wii activities were less successful with clients who had significant cognitive and/or physical disabilities.

Abstract
The purpose of this study was to: (1) determine energy expenditure (EE) during a range of active video games (AVGs) and (2) determine whether EE during AVGs is influenced by gaming experience or fitness. Twenty-six boys (11.4+/-0.8 years) participated and performed a range of sedentary activities (resting, watching television and sedentary gaming), playing AVGs (Nintendo((R)) Wii Bowling, Boxing, Tennis, and Wii Fit Skiing and Step), walking and running including a maximal fitness test. During all activities, oxygen uptake, heart rate and EE were determined. The AVGs resulted in a significantly higher EE compared to rest (63-190%, p/=0.001) and sedentary screen-time activities (56-184%, p/=0.001). No significant differences in EE were found between the most active video games and walking. There was no evidence to suggest that gaming experience or aerobic fitness influenced EE when playing AVGs. In conclusion, boys expended more energy during active gaming compared to sedentary activities. Whilst EE during AVG is game-specific, AVGs are not intense enough to contribute towards the 60min of daily moderate-to-vigorous physical activity that is currently recommended for children.
