    What can you do with a Wii Balance Board?

    The Wii Balance Board accessory was created from the ground up to work with Wii Fit. The Wii Balance Board can read your real-life movements and bring them to life on screen.

    Why does my Wii fit board flashes blue?

    If the blue light is blinking or is not on at all, then there is a synching problem. Try re-syncing the board with your Wii by finding the small red sync button on the Wii (located on the front of the console under the SD card door) and the sync button on the Wii Fit Board (located under the battery door.)

    Is the Wii Balance Board Bluetooth?

    The Wii Balance Board is the bundled input device with the Wii game Wii Fit. It is a wireless device, using standard Bluetooth technology to communicate with the Wii.

    Can two Wii Balance Boards same time?

    Yes, two people can play at the same time – only one Balance Board is needed.

    Can you use 2 Balance Boards same time Wii?

    Wii Fit U does not support the use of multiple balance boards simultaneously. So technically, the wii does have the capability to listen two balance boards, but none of the software supports it, so having more than one is superfluous.

    Why won’t my Wii board connect?

    If you’re experiencing problems with your Wii Balance Board, chances are that it is not properly synchronised with (or in other words, “connected to”) your Wii console. To do this simply insert the Wii Fit Plus disc and start the game. You’ll see the light on the Power Button of the Wii Balance Board flash.

    Can you calibrate a Wii Balance Board?

    The balance board is not calibrated properly. When calibrating your balance board, try using as little weight as possible; you can press down with both your hands or use two handheld weights for instance.

    How do you sync a Wii U balance board?

    Complete these steps

    1. Press the SYNC Button on the front of the Wii U once.
    2. Remove the battery cover from the bottom of the Wii Balance Board to reveal the SYNC Button.
    3. Press the SYNC Button once.
    4. A blue light on the Wii Balance Board Power Button will blink.

    What are the Wii Balance Board foot extensions for?

    A set of foot extensions is available to allow the board to be used on softer surfaces. The extension feet are included with some versions of the Balance Board, but not in European versions. The balance board should be used bare-footed; socks do not properly grip the hard surface, and can create a danger.

    How do you install Wii foot balance board extensions?

    Complete these steps Turn the Wii Balance Board over and remove any dust or dirt from the Balance Sensors. Carefully push the foot extensions straight onto the sensors. Make sure they are pushed on all the way to assure that the board will lay flat and stable. Return the board to the normal operating position.

    How many Wii Fit boards can be used?

    The Wii Balance Board Extension has been successfully tested with up to four balance boards each connected to unique instances of LabChart in the same 24′ x 14′ (7.3 m x 4.3 m) room in the presence of one WLAN.

    Does the Wii board work on carpet?

    User Info: dantez72. Its says in the manual do not use it on thick carpet. The only problem you would have on a carpet is if its that thick its pushing on the under side of the board which would stop the 4 corner legs (which are the sensors) from touching the ground.

    Can you use a balance board on carpet?

    For beginners, the best surface for a balance board is one with thick carpeting. In addition to offering a softer landing if you fall, a thick carpet will give you a slower and more even roll. This will make it easier to stand on your board while you work to stay in control.

    Can you lose weight with the Wii Fit?

    In order to lose weight, you must burn more calories than you take it. The Wii Fit allows you to set a daily goal of calories burned through exercise. At the end of each workout, the game will tell you how many calories each activity burned, making it simple to keep track of the amount of exercise needed.

    Abstract

    Background

    Almost all epidemiological studies over the past 40 years have determined that the incidence of fragility fractures is increasing. Therefore, the assessment of postural stability and monitoring any progress during balance training for geriatric patients to prevent falls are becoming more important. The Nintendo® Wii Fit Balance Board, with its integrated software and scoring system, might be a cheap and easily accessible tool for this purpose.

    Methods

    This prospective study analyzed the diagnostic value of the Wii Fit Balance Board in 41 healthy subjects using two measurements: the yoga task “tree,” which is performed in one-leg stance; and the balance game “table tilt.” Our investigation compared these tasks to two established, regularly used systems, the MFT-S3 Check and the Posturomed, by looking for correlation and agreement, using Bland–Altman plots, as well as for differences to demographic data. All measurement tools were also compared to the Sensory Organization Test—the gold standard for detecting impaired balance.

    Results

    We found a moderate correlation between the yoga exercise “tree” and the Sensory Organization Test (correlation coefficient r = 0.514, p = 0.001) as well as the MFT-S3 Check (r = 0.356–0.472, p = 0.002–0.022) and the Posturomed (r = 0.345, p = 0.027). However, results from the balance game “table tilt” did not show a significant correlation with those of the systems to which we compared it (p = 0.301–0.953).

    Conclusions

    According to the literature, the raw data from the Wii Fit Balance Board are comparable to that obtained by laboratory-grade force platforms. We have found, however, that the yoga pose “tree,” as integrated into the Nintendo® Wii Fit Balance Board with its own scoring system, also correlates with the gold-standard Sensory Organization Test. It also correlates with two frequently used diagnostic and therapeutic devices. We, therefore, conclude that the Wii Fit Balance Board is suitable for the evaluation of postural stability and may be useful in preventing falls among the geriatric population.

    Level of evidence

    2b.

    Background

    With demographic changes leading to an increase in fragility fractures, the need for postural stability training and testing is becoming more important medically, in particular among trauma and orthopedic surgeons. In 2005, there were nearly 2 million fragility fractures in the United States alone, a number expected to rise to more than 3 million by 2025 [1].

    Fragility fractures are associated with major morbidities, loss of independence and increased mortality [2, 3] and lead to a moderate-to-high-risk of further falls [4]. Restoring mobility is, therefore, crucial to enabling elderly people to walk around freely, preserve autonomy and maintain social engagement.

    Rubenstein et al. identified gait or balance disorders as a major cause of falls in elderly adults [5]; Ganz et al. reported that the most consistent predictors of future falls, with a likelihood ratio range of 1.7–2.4, were pre-existing gait and balance disorders [6]. Tactile sensitivity, joint movements, muscle strength, and vision all decrease with age; so does postural stability [7]. Improving postural stability in the elderly, therefore, seems crucial to reducing the likelihood of falls.

    Postural stability is defined as the ability to control one’s body’s center of gravity within a given base of support [8]. Hence, as Hauer et al. showed, intensive balance and muscular strength training can lead to a reduction in falls compared to a control group [9].

    Screening for risk of, and preventing, falls is not easy given the complexity of possible causes, but posturographic analysis is a promising way to identify individuals at risk of falling due to inadequate postural stability. Yet strategies to prevent falls often remain underutilized [10], because systems for measuring postural control are often expensive and time consuming (due to the complexity of analyzing test results) and, therefore, restricted to specialist institutions [11].

    Home-based assessment and training would thus seem more ideal [9]. To this end, the Nintendo® Wii Fit Balance Board (Nintendo, Kyoto, Japan), priced at around $100, might be an inexpensive and readily available tool. It is a sports-and-fitness device consisting of a force platform linked via Bluetooth to a video game console. Its integrated software, “Wii Fit,” contains 48 tasks divided into 4 groups: yoga, strength training, aerobics, and balance games.

    By comparing the Wii Fit Balance Board to a laboratory-grade force platform, Clark et al. have already been able to prove its reliability and validity [12]. However, this was done by extracting raw data from the Wii rather than using the Wii Fit software’s integrated scoring system. Therefore, as a feasibility study, this project aimed at evaluating objectively the possibility of using the Wii Fit Balance Board as a postural stability diagnostic tool with its integrated scoring system, hypothesizing, that the results are comparable to the SOT, the gold standard in equilibrium analysis [13], as well as to certain other, well-established diagnostic and therapeutic devices, namely the MFT-S3 Check and Posturomed within a healthy population. To further evaluate the diagnostic relevance of the tools, we also checked for demographic differences among the study participants that may have affected the results.

    Methods

    All volunteers provided oral and written consent to participate in this study and could discontinue at any time. The procedure for the study was approved by the RWTH Aachen ethics committee (EK 295/12) and conducted in accordance with the Declaration of Helsinki.

    An orthopedic as well as an otorhinolaryngologic medical examination was conducted to confirm whether the subjects were capable of participating in this study, in which we included healthy adults (≥ 18 years of age). Exclusion criteria were: known deformities in or injuries to the spine, pelvis, or lower extremities; a pathological H.I.N.T.S (Head Impulse Test, Nystagmus und Test of Skew); incompliance; and underlying diseases attended by substantial restrictions such as diabetes or rheumatoid arthritis.

    All subjects underwent testing with the Wii Fit Balance Board as well as with the Sensory Organization Test (SOT) (NeuroCom®, Pleasanton, USA), the MFT-S3 Check (TrendSportTrading GmbH, Großhöflein, Austria), and the Posturomed (Haider Bioswing GmbH, Pullenreuth, Germany).

    The Wii Fit Balance Board consists of a force platform with four pressure sensors (FL, FR, BL, and BR) which detect the force applied to the sensors as well as shifts in the center of balance through changes in the vector of the center of pressure (CoP), as depicted in Fig. 1.

    We selected two of the integrated exercises for their high demands on postural stability, as well as for the similarity of testing compared to the MFT-S3 Check and the Posturomed. Our two selected exercises were the yoga-task “tree,” which calls for a one-legged stance, and the balance game “table tilt,” a task that requires great coordination in which the center of pressure must be shifted so as to roll a virtual ball into a pocket on a monitor. Figures 2, 3 show the setup, including the monitor used for visual feedback.

    On the one hand, those two tasks differ in their respective aim: the yoga-task “tree” focuses on maintaining balance, whereas the subject intentionally transfers their center of pressure in the balance game “table tilt”. On the other hand, the scoring system also differs, as the yoga-task “tree” grades the result based on the deflection of the center of pressure (nominal value) and the balance game “table tilt” rewards points for accomplished levels (ordinal value).

    The MFT-S3 Check utilizes an unstable platform connected to a base plate via the horizontal axis. This allows lateral pivoting of up to 12° to either side. The integrated sensors measure stability, sensory-motor regulatory capacity, and functional muscular asymmetry. By measuring the frequency and amplitude of sway, the system calculates a composite index for overall stability and sensory-motor capacity from 1 to 9, with 1 being the best score and 9 being the worst [13].

    The Posturomed consists of an unstable platform suspended from four mountings and thus hanging in mid-air. Measurements are taken with the subject performing a one-legged stance on either leg. The amplitude and frequency of the movements of the platform are monitored, and a total score from 0 to 1000 is calculated [14].

    The SOT utilizes six sensory conditions to evaluate a person’s standing balance. The SOT is administered with a computerized system using a movable dual forceplate and a movable visual screen. The SOT protocol assesses the patient’s ability to make effective use of visual, vestibular, and proprioceptive inputs as well as to suppress inaccurate sensory information. Differences in how much the patient’s body sways under the various sensory conditions determine their measured ability to organize and select the appropriate sensory information they need to maintain postural control [15]. The measurements result in an equilibrium score that ranges from 100 (no body sway) to 0 (fall) [16].

    We conducted all measurements in the same order (SOT, Wii Fit, Posturomed, and MFT S3 Check), and all measurements were performed three times. A laboratory assistant supervised the subjects throughout the testing. The tests were performed with patients not wearing shoes and in a comfortable standing position with arms hanging down. The surroundings during testing were selected so as to be disturbance free.

    Statistical analysis

    Statistical analysis was based on the recommendations of the local department for medical statistics. Given the different scoring systems used in the diagnostic tools under comparison, we converted the given value (x) by defining a maximum value (a) and a minimum value (b) for each measurement and generated a standardized value between “0” (worst score) and “1” (best score) using the following equation:

    $$ {\text{Standardized value}}\, = \,\frac{x - b}{a - b}. $$

    The three results for each diagnostic tool were averaged for statistical analysis, which was conducted with SPSS version 21 (SPSS inc., Chicago, USA) after testing for Gaussian distribution using the Kolmogorov–Smirnov test.

    To analyze the relationship between the measurements, we used Pearson’s correlation. A correlation coefficient of 0.90–1.00 is sign of a very strong correlation; a coefficient of 0.70–0.89 represents a strong correlation; a coefficient of 0.4–0.69 represents a moderate correlation; 0.10–0.39 represents a weak correlation; and a coefficient of 0.00–0.09 represents a negligible correlation [17]. Furthermore, we conducted Bland–Altman plots to check for agreement as well as for possible bias.

    To further characterize the diagnostic tools, we examined potential differences in demographic data. Nutritional status was measured using the body mass index (BMI) and participants were divided into the following groups according to the WHO [18]: catergory 1 (underweight) = BMI (kg/m2) < 19.9 (n = 7); category 2 (normal weight) = BMI 20.0–24.9 (n = 22); category 3 (overweight) = BMI 25.0–29.9 (n = 12).

    Age was divided into groups as well (category 1: < 20 years (n = 9); category 2: 20–29 years (n = 23); category 3: 30–39 years (n = 3); category 4: 40–49 years (n = 2); category 5: > 50 years (n = 4).

    Differences in the subjects’ demographic data were analyzed using paired t tests and ANOVAs.

    The level of significance was set at p < 0.05.

    Results

    A total of 41 subjects (21 females, 20 males) were examined in this study. The average age of the subjects was 27.9 years (SD ± 12.1), the youngest being 18 years of age, the oldest 70. They averaged 1.78 m (SD ± 0.11) and 73.5 kg (SD ± 17.1) in height and weight, thus averaging a BMI of 23.0 kg/m2 (SD ± 17.1).

    Analyzing the relationship between the scores on the Nintendo Wii and the test results from the established systems, we found considerable differences between the two selected tasks on the Wii Fit. Results for the yoga task “tree” significantly correlated with those of the SOT, doing so with a moderate correlation (r = 0.514; p = 0.001); however, there was no significant correlation between those of the SOT and the “table tilt” game (p = 0.301; r = 0.166). This difference also becomes evident when we view the Bland–Altman plots shown in Figs. 4, 5.

    When we compare the Wii Fit’s “tree” yoga pose to the SOT, the Bland–Altman plot shows a certain bias, and furthermore a trend, as the difference between the results decreases with higher mean values. When we compare the Wii Fit’s “table tilt” game with the SOT, we see a bias as well as a linear relationship between the means and the difference; this shows that both results differ significantly.

    Analyzing the relationships between the SOT (as the gold standard) and each of the established systems, we also find a significant correlation for the results of the MFT-S3 Check (sensorimotor index: r = 0.404; p = 0.009, and stability index: r = 0.347; p = 0.011). For the Posturomed, on the other hand, no significant correlation with the SOT could be detected (p = 0.242).

    Examining the relationships between the Nintendo Wii Fit and both the MFT-S3 Check as well as the Posturomed, we found a significant correlation between the yoga task “tree” and both of the other measurement tools as shown in Table 1:

    Furthermore, we assessed gender and demographic differences for each measurement tool.

    As far as gender differences are concerned, we found no significant differences for either Wii Fit Balance Board measurement (p = 0.0368, p = 0.99); nor did we find significant differences for the SOT and Posturomed (p = 0.781 and p = 0.559, respectively). The MFT-S3 Check was the only system for which a difference was found, with women scoring significantly higher (p = 0.004), with a mean value of 0.502 (SD 0.264), than men did, with a mean value of 0.355 (SD 0.236).

    As far as nutritional status is concerned, the MFT-S3 Check was likewise the only diagnostic device to show significant differences (p = 0.001).

    Bonferroni post hoc testing found a significantly higher score for the underweight category 1 group, with a mean value of 0.808 (SD 0.179), than there was for the other groups (p = 0.001–0.004). Directly comparing groups 2 (mean value 0.458; SD 0.249) and 3 (mean value 0.332; SD 0.209) revealed no significant difference (p = 0.246). However, there was a significant (p = 0.000) negative correlation between the results of the MFT-S3 Check and BMI (r = − 0.529).

    The results of the SOT (p = 0.4), Wii Fit Balance Board (p = 0.128; p = 0.320), and Posturomed (p = 0.939) showed no significant differences as to nutritional status.

    As far as the age of the subjects is concerned, only the yoga-task “tree” on the Nintendo Wii showed significant differences between the various age groups (p = 0.017). Post hoc analysis detected significant differences between age groups 1 (mean 0.694; SD 0.191) and 5 (mean 0.393; SD 0.239) p = 0.020; between groups 2 (mean 0.746; SD 0.210) and 5 (p = 0.031); and between groups 3 (mean 0.915; SD 0.072) and 5 (p = 0.021). Pearson’s correlation detected a significant, yet weak negative correlation between the results and the age of the subjects, of r = − 0.35 (p = 0.025).

    The “table tilt” balance game on the Nintendo Wii did not reveal any significant difference between the age groups (p = 0.387). The established systems were likewise unable to measure significant differences in postural stability among the age groups (SOT: p = 0.571; MFT-S3 Check: p = 0.883; Posturomed: p = 0.641).

    Discussion

    In this study of 41 healthy subjects, we showed that the Wii Fit yoga-task “tree” significantly correlates with the established system on direct comparison. There is a weak-to-moderate correlation between all systems and the Wii Fit yoga-task “tree” (r = 0.345–0.514). The reason for the correlation being not greater than weak to moderate could be that even though all devices aim at identifying balance or imbalance, they all have different approaches to measuring it. Furthermore, the scoring system differs between the devices. To properly analyze and compare the measurements, a general score has been calculated, which might lead to a bias.

    The Bland–Altman plots also showed that the methods generally produce different results. But there is an obvious relationship between the respective results nonetheless, and the difference between the results decreases when subjects score highly. This effect can be seen upon comparing the yoga-task “tree” on Wii Fit with the SOT as well as the Posturomed. We, therefore, conclude that the measurement method in combination with the software underlying the yoga-task “tree” can be considered an adequate diagnostic tool.

    The results for the Nintendo Wii Fit’s game “table tilt,” however, do not correlate with the other measurement tools at all. The Bland–Altman plot furthermore showed an obvious trend, with a substantial bias; and “table tilt” should therefore not be considered adequate as a diagnostic device.

    When it comes to demographic differentiations, the results of the Nintendo Wii Fit Balance Board should comply with literature. Here it is stated that the age adversely affects postural stability [19], which is in line with the results of the “tree” pose on Wii Fit, especially showing, that the age group > 50 years scores significantly lower. But the Wii Fit was unable to differentiate between genders or various nutritional states despite the statement by Hue et al. that decreasing postural stability is strongly correlated to increasing body weight [20]. As far as gender differences are concerned, several studies have been unable to identify a significant difference in postural stability [21,22,23].

    Regarding the established systems both SOT and Posturomed could not detect differences regarding gender, age, or nutritional status. Only the MFT-S3 Check was able to detect differences in the nutritional status as well as in gender with women scoring significantly higher.

    Since postural instability is a risk factor for falls, especially in the population aged 65 years of age or older [24, 25], screening for instability is an important step toward preventing the falls associated with fragility fractures. Therefore, the detection of postural instability can either be used as a tool for secondary or tertiary prevention, but can also be used for primary prevention, for example by a general physician. To achieve that, measurement tools should be widely achievable and cost-efficient, which is the case with the Nintendo Wii Fit Balance Board.

    Furthermore, studies have shown that proprioceptive training is effective in older adults at improving postural stability, static and dynamic balance, helping lower the risk of suffering a fall [26]. Additionally, a systematic review has found higher adherence to technology-based programs, such as the Wii Fit, compared to regular exercise programs [27], when it comes to continuing a training program.

    Numerous studies have indicated that the Wii Fit Balance Board could be used to treat the imbalance symptoms of diseases such as Parkinson’s, cerebral palsy, stroke, multiple sclerosis, or vestibular disorders [28, 29]. Further applications of this system include rehabilitation after injury to or surgery on the lower extremities as well as injury prevention in athletes [30,31,32].

    This shows that the Nintendo® Wii Fit Balance Board can be used not only as a diagnostic but also as a therapeutic device. This sets the Wii apart from many other tools, for example the Sensory Organization Test.

    Examining the Wii Fit Balance Board, Chang et al. furthermore showed that it provides highly reliable measurements in the elderly as well as a good intra-class correlation and a high correlation with the results of the Balance Master System® (NeuroCom®, Pleasanton, USA). For their study, however, they obtained and analyzed raw data from the Wii Fit Balance Board using software they designed themselves [33]. Unlike our study, in which we make use of software already integrated into the Nintendo®, that approach contains a limitation on the usefulness of the Wii Fit Balance Board because of the technical difficulty of extracting raw data from the Wii, and because of the question of making a software widely available for analyzing the raw data.

    But since this is the first study providing evidence for the use of Nintendo`s integrated software and scoring system as a tool for assessing postural stability, the limitations of our study must be considered.

    The Nintendo Wii Fit Balance Board can be considered a portable and low-cost posturography system to monitor improvements or a decline in postural stability of one individual. But, further studies are necessary to determine the normative values as well as a cut-off value to detect people with an increased risk of falling.

    Furthermore, we primarily studied young and healthy individuals; and thus, further studies must evaluate the practicability of this technique among a geriatric patient population. While all measurement tools are designed to evaluate postural stability and the sense of equilibrium, each comes with its own approach to measurement, which impedes any direct comparison.

    Conclusions

    With this study, we have been able to show that the Wii Fit Balance Board, specifically its yoga-task “tree”, achieves differentiated results as compared to more established systems and can, therefore, be used as a portable, low-cost posturography system. However, normative values for the Nintendo Wii Fit Balance Board have yet to be determined when it comes to assessing patients’ risk of suffering a fall. Further studies are needed to address this issue.

    Wii Balance Board

    Accessory for the Wii and Wii U

    ‹ The templateInfobox information appliance is being considered for merging. ›

    The Wii Balance Board (Japanese: バランスWiiボード, Hepburn: Baransu Wī Bōdo) is an accessory for the Wii and Wii U video game consoles.[1] Unlike the usual balance board for exercise, it does not rock but instead tracks the user's center of balance. Along with Wii Fit,[2] it was introduced on July 11, 2007 at the Electronic Entertainment Expo.

    Design[edit]

    The top and bottom of the Wii Balance Board, without foot extensions

    The Wii Balance Board is shaped like a household body scale, with a plain white top and light gray bottom. It runs on four AA batteries as a power source, which can power the board for about 60 hours.[3] The board uses Bluetooth technology and contains four pressure sensors that are used to measure the user's center of balance—the location of the intersection between an imaginary line drawn vertically through the center of pressure and the surface of the Balance Board—and weight. In an interview conducted by gaming web site IGN, Shigeru Miyamoto stated that the Balance Board's ability to measure weight is probably more accurate than that of a typical bathroom scale.[4]

    Although the Japanese packaging states that it is designed to support people weighing up to 136 kilograms (300 pounds) and the "Western" Balance Board up to 150 kg (330 pounds), they are actually the same board. The packaging differs due to regulatory differences between Japan and the United States. The sensors on the board can accurately measure up to 150 kg (330 pounds). The actual physical structure of the board can withstand much greater force equivalent to around 300 kg (660 pounds).[5]

    Due to the similarities between the two products, the Wii Balance Board has been compared to the Joyboard, a peripheral released for the Atari VCS in 1982 by Amiga Corporation.[6] The technology in the Joyboard was less advanced than that in the Wii Balance Board, with four directional switches instead of pressure sensors.[6]

    The manual says that the Balance Board should only be used on a hard surface or thin carpet, as thicker or softer surfaces may cause the board to operate incorrectly. A set of foot extensions is available to allow the board to be used on softer surfaces. The extension feet are included with some versions of the Balance Board, but not in European versions.

    The balance board should be used bare-footed; socks do not properly grip the hard surface, and can create a danger. Novelty Wii Fit non-skid socks, which have small rubber pads on the sole that do not slide easily, were provided to members of Club Nintendo.

    Development[edit]

    The balance board's development was tightly coupled with the development of the Wii Fit game. Nintendo initially contacted manufacturers of normal bathroom scales, but ended up building the board without their help in an effort to keep down costs. In early development models, the balance board was a simple scale with one load cell. However, the developers realized that a simple scale was not useful as a game accessory and expanded the number of load cells to two, then four. The idea to use multiple sensors was partly inspired by how sumo wrestlers weigh themselves (using two scales).[7] The shape of the balance board was initially a square, but it was decided that it was too hard to use for the exercises.

    For a large part of the development process, the board was an extension controller to a normal Wii remote.[7] The effects of this are seen in the released balance board, which acts as a Wii remote with the front button mapped to "A" and all load cells on an "extension controller".[8]

    Software[edit]

    Main article: List of games that support Wii Balance Board

    Wii Fit is the first game to have made use of the Wii Balance Board. Shortly after Wii Fit's release, Shigeru Miyamoto noted the potential for other uses, stating that "probably the simplest and most straightforward [idea] would be a snowboarding game".[9] Miyamoto has also stated that Nintendo received "many inquiries" from third parties following the announcement of Wii Fit and the Wii Balance Board,[10] as well as receiving interest from the physical fitness industry.[10]

    We Ski by Bandai Namco Games is the first third-party game to have made use of the Wii Balance Board, in conjunction with the Wii Remote and Nunchuk attachment.[11]

    The Wii Balance Board is officially compatible with both Wii and Wii U. Only one Balance Board can be synchronized with the system at a time and the board uses the fourth player controller connection, replacing any Wii Remotes that are currently bound to that position. Due to these two limitations, there is no ability to use multiple Balance Boards simultaneously[12] and the maximum number of players who can play a non-hotseat multiplayer mode involving it is reduced to 3. Some homebrew developers allowed the board to be unofficially supported by the Linux kernel 3.7.[13]

    Measuring center of pressure displacement[edit]

    A shift of center of pressure (CoP) is an indirect measure of postural sway and thus a measure of a person’s ability to maintain balance. Though originally designed as a video game controller, the Balance Board has become a tool for assessing CoP which has proven to be both valid and reliable. Clark et al. performed a study to prove the validity and test-retest reliability of the use of a Balance Board. The reason to use a Balance Board instead of a force platform is the ability to "create a portable, inexpensive balance assessment system that has widespread availability.” Four standing balance tasks were used in this study including a combination of double stance, single stance, eyes open, and eyes closed. Throughout these tests the center of pressure path length was measured and compared to data from an identical study on a laboratory-grade force platform. The study found Balance Board measurements to be reliable and consistently repeatable.[14]

    Use to improve balance[edit]

    Several studies have been carried out to determine the effects of programs utilizing the Nintendo Wii console and balance board on balance control and functional performance in independently functioning older adults. In a meta-analysis, seven studies were examined, four comparing Wii exercise with no exercise, and three comparing with other exercise programs. It was found that results with the Wii were better than no exercise, and comparable with other programs in improving balance control. However, the analysis concluded that "definitive recommendations as to optimal treatment protocols and the potential of such an intervention as a safe and effective home-based treatment cannot be made at this point".[15]

    Reception[edit]

    The Wii Balance Board sold 32 million units worldwide between its launch and November 2010, and set a new Guinness World Record for "best-selling personal weighing device". By January 2012, it had sold 42 million units.[16]
