Effects of Short-Term Training of Community-Dwelling Elderly with Modular Interactive Tiles

Efficacy of interactive video gaming in older adults with memory complaints: A cluster-randomized exercise intervention

Purpose

The effects of aging on physical and mental health may be ameliorated by regular participation in physical activity (PA). There is also evidence for the benefits of various training modalities on cognition and functional ability in older adults. The aim of this study was to compare effects of a 12-week active video gaming intervention (X Box Kinect Sports) to conventional multimodal supervised exercise on fitness, functional ability and cognitive performance in older adults with memory complaints.

Methods

Participants (n = 45, 72±5 yrs.) were recruited from 6 retirement homes and cluster-randomized into the Interactive Video Gaming (IVG) group (N = 23) or Conventional Multimodal (CM) group (N = 22), meeting 2 x 1 hour sessions, weekly for 12 weeks. Pre-post measures included: 6 min walk, timed up and go, dynamic balance, functional reach, Mini-Mental State Examination, N-back Task and the Modified Stroop task.

Results

The IVG group demonstrated significant improvement in the total number correct responses on the Stroop task (P = 0.028) and for average reaction time of correct colour-words (P = 0.024), compared to the CM group. Functional ability improved significantly in the IVG group, including the 6-min walk (P = 0.017), dynamic balance (P = 0.03), timed up and go (P<0.001) and functional reach (P<0.0010).

Conclusion

An active interactive video gaming intervention was more effective than conventional multimodal exercise in improving executive and global cognitive performance and functional capacity in older adults with subjective memory complaints.

Effects of Kinect exergames on balance training among community older adults: A randomized controlled trial

BACKGROUND

Recent years have witnessed wide applications of exergames to balance training among the older adults. However, research concerning balance training with the use of Kinect for Xbox has remained scarce. While previous studies have shown the positive effects of exergames on improving balance and preventing falling among the older adults, there has been a paucity of empirical evidence supporting the superiority of Kinect exercise to conventional exercise over balance training among the older adults. Therefore, this study aimed to compare the feasibility, safety, and effectiveness of Kinect exercise against conventional exercise over balance training among the community older adults.

METHOD

A total of 20 participants were randomly assigned to the Kinect Exercise Group (N = 10) or the Conventional Exercise Group (N = 10) for a 5-week balance training (45 minutes a time, 2 times a week). Assessor blinding was employed to assess the participants' performance before and after the treatment, including 30-Second Chair Stand Test (30-sec CST), Timed Up and Go (TUG), Functional Reach Test (FRT), and One-Leg Stance Test (OLST) respectively with eyes open and closed. Subjective feeling of the intensity of pain and side effects were recorded throughout the investigation period. Nonparametric statistics was used for data analysis.

RESULTS

Within-group comparison between the pre-test and post-test indicated that significant differences existed in all of the 5 tests (30-sec CST, TUG, FRT, OLST with eyes open, and OLST with eyes closed) in the Kinect exercise group. To the Conventional exercise group, however, significant differences were only observed in 30-sec CST, FRT and OLST with eyes open. With regard to between-group comparison, significant differences were only found in FRT.

CONCLUSION

Such results indicated that both treatments were helpful in improving the participants' balance performance, that Kinect exercise was more effective in terms of overall balance ability, and that Kinect exercise was particularly beneficial to functional reach enhancement in comparison with traditional exercise. Kinect exercise could be a feasible, safe, and effective alternative for dynamic balance training among older adults.

Static and Dynamic Balance in Adults Undergoing Lumbar Spine Surgery: Screening and Prediction of Postsurgical Outcomes

INTRODUCTION

Balance and fall risk before and after lumbar surgery was assessed to determine whether balance at baseline predicts long-term postsurgical outcomes.

METHODS

Forty-three patients in the United States and Israel performed the single-leg stance (SLS) test, four square step test (FSST), and 8-foot up-and-go (8FUG) test before and 2 to 4 months after lumbar spine surgery. They completed the Oswestry Disability Index (ODI) and pain rating before and 12 months after lumbar surgery.

RESULTS

From baseline to follow-up, the SLS time was 3.74 seconds longer (P = 0.01), the FSST time was 1.94 seconds faster (P < 0.001), and the 8FUG time was 1.55 seconds faster (P = 0.02). Before surgery, 26% of the patients were considered high fall risk according to the FSST and 51% according to the 8FUG. Postsurgery, all patients could complete the physical tests, but 26% remained at high fall risk according to the 8FUG and 7.5% according to the FSST. The three physical measures together explained 30% of the variance in postsurgical ODI scores (P = 0.02). Age was not correlated with performance.

DISCUSSION

Risk of falling is higher than surgeons suspect. Balance tests (ie, SLS, FSST, and 8FUG) are quick and easy to administer. The findings support the importance of screening for balance and fall risk in adults undergoing lumbar spine surgery.

Effects of Playful Exercise of Older Adults on Balance and Physical Activity: a Randomized Controlled Trial

There is evidence that one of the most important approaches to improving the healthy ageing of older adults is for them to carry out daily physical activity. However, motivation to engage in physical activity is often low in old age. This study investigated the potential of engaging older adults in playful exercise to increase physical activity and balance. A randomised control trial (RCT) was performed with 26 independently living older adults (initially 38, but 12 were lost to illness or death during the course of the project), mean age 83.54 (SD: 7.12), 19 women. Participants were randomly allocated to intervention (n = 16) or control (n = 12) (originally 19 in each group). The intervention consisted of playful exercise on Moto tiles 6 * 2 min twice a week over 10 weeks, while control group participants engaged in normal daily activities.

The intervention group participants improved functional balance (Berg’s Balance Score) by an average of 5.02 points, and the control group by 2.58 points (p = 0.11). No between-group difference was observed in physical activities outside exercise sessions (p = 0.82). The difference in gain of balance as measured by BBS was below statistical significance, as a result of the sample size being too small. However, trial results suggest that older pre-frail and frail adults who engage in a moderate playful exercise programme over at least 10 weeks may potentially experience a modest gain in balance. Moreover, the playful exercise created a joyous social atmosphere among the participants who spontaneously remarked that the play sessions were much more fun than their standard light exercise programme of one hour twice a week. This motivational outcome is important for adherence to any exercise programme and indeed for general well-being.

Contrasting performance between physically active and sedentary older people playing exergames

The increase in life expectancy associated with the increase in chronological age and less active people helps in the appearance of chronic and degenerative diseases. The encouragement of physical exercises contributes to older people abandoning sedentarism and preventing such diseases. Exergame is a promising alternative, for making exercise a pleasurable activity.In this study, we compared the performance of physically active older people with sedentary older people in exergames.Participants were 83 older adults over 65 years of age, of both sexes, divided into 2 physically active older people (AG) and sedentary older people (CG) groups. The participants performed a task through an exergame called "MoviLetrando" that uses the score, number of hits, number of omissions, and an average time of hits as an evaluation. A characterization questionnaire was applied, with information about sex, age, marital status, economic class, self-rated health, time of use of electronic games, a questionnaire on the practice of physical activity, and the Brunel Mood Scale.There was a higher exergame score in AG than in CG (P = .003), in the number of correct answers (P = .012). The number of omissions was lower in AG than in CG (P = .023). The mean time of correct answers was lower in AG than in CG (P = .013). The regression analysis revealed a significant finding F (3, 82) = 11.06, P < .001 and showed a prediction ability of 26.9% (r = .269). Three variables remained significantly associated with the score: physical activity was marginally significant (β = .19, P = .06), age (β = -.403, P < .001), depression (β = -.212, P = .028).Physically active older people perform better when compared with the sedentary older people. Age, depression, and physical activity influence the performance in exergame.

Study protocol: effect of playful training on functional abilities of older adults - a randomized controlled trial

Background

Loss of functional capabilities due to inactivity is one of the most common reasons for fall accidents, and it has been well established that loss of capabilities can be effectively reduced by physical activity. Pilot studies indicate a possible improvement in functional abilities of community dwelling elderly as a result of short-term playing with an exergame system in the form of interactive modular tiles. Such playful training may be motivational to perform and viewed by the subjects to offer life-fulfilling quality, while providing improvement in physical abilities, e.g. related to prevent fall accidents. The RCT will test for a variety of health parameters of community-dwelling elderly playing on interactive modular tiles.

Methods

The study will be a single blinded, randomized controlled trial with 60 community-dwelling adults 70+ years. The trial will consist an intervention group of 30 participants training with the interactive modular tiles, and a control group of 30 participants that will receive the usual care provided to non-patient elderly. The intervention period will be 12 weeks. The intervention group will perform group training (4–5 individuals for 1 h training session with each participant receiving 13 min training) on the interactive tiles twice a week. Follow-up tests include 6-min Walk Test (6MWT), the 8-ft Timed Up & Go Test (TUG), and the Chair-Stand Test (CS) from the Senior Fitness Test, along with balancing tests (static test on Wii Board and Line Walk test). Secondary outcomes related to adherence, motivation and acceptability will be investigated through semi-structured interviews. Data will be collected from pre- and post-tests. Data will be analyzed for statistically significant differences by checking that there is a Gaussian distribution and then using paired t-test, otherwise using Wilcoxon signed-rank test. “Intention to treat” analysis will be done.

Discussion

The trial tests for increased mobility, agility, balancing and general fitness of community-dwelling elderly as a result of playing, in this case on modular interactive tiles. A positive outcome may help preventing loss of functional capabilities due to inactivity.

Serious Games for Health: The Potential of Metadata

OBJECTIVE

Numerous serious games and health games exist, either as commercial products (typically with a focus on entertaining a broad user group) or smaller games and game prototypes, often resulting from research projects (typically tailored to a smaller user group with a specific health characteristic). A major drawback of existing health games is that they are not very well described and attributed with (machine-readable, quantitative, and qualitative) metadata such as the characterizing goal of the game, the target user group, or expected health effects well proven in scientific studies. This makes it difficult or even impossible for end users to find and select the most appropriate game for a specific situation (e.g., health needs). Therefore, the aim of this article was to motivate the need and potential/benefit of metadata for the description and retrieval of health games and to describe a descriptive model for the qualitative description of games for health. It was not the aim of the article to describe a stable, running system (portal) for health games. This will be addressed in future work.

METHODS

Building on previous work toward a metadata format for serious games, a descriptive model for the formal description of games for health is introduced. For the conceptualization of this model, classification schemata of different existing health game repositories are considered. The classification schema consists of three levels: a core set of mandatory descriptive fields relevant for all games for health application areas, a detailed level with more comprehensive, optional information about the games, and so-called extension as level three with specific descriptive elements relevant for dedicated health games application areas, for example, cardio training.

CONCLUSION

A metadata format provides a technical framework to describe, find, and select appropriate health games matching the needs of the end user. Future steps to improve, apply, and promote the metadata format in the health games market are discussed.

Exercise and rehabilitation delivered through exergames in older adults: An integrative review of technologies, safety and efficacy

BACKGROUND

There has been a rapid increase in research on the use of virtual reality (VR) and gaming technology as a complementary tool in exercise and rehabilitation in the elderly population. Although a few recent studies have evaluated their efficacy, there is currently no in-depth description and discussion of different game technologies, physical functions targeted, and safety issues related to older adults playing exergames.

OBJECTIVES

This integrative review provides an overview of the technologies and games used, progression, safety measurements and associated adverse events, adherence to exergaming, outcome measures used, and their effect on physical function.

METHODS

We undertook systematic searches of SCOPUS and PubMed databases. Key search terms included "game", "exercise", and "aged", and were adapted to each database. To be included, studies had to involve older adults aged 65 years or above, have a pre-post training or intervention design, include ICT-implemented games with weight-bearing exercises, and have outcome measures that included physical activity variables and/or clinical tests of physical function.

RESULTS

Sixty studies fulfilled the inclusion criteria. The studies had a broad range of aims and intervention designs and mostly focused on community-dwelling healthy older adults. The majority of the studies used commercially available gaming technologies that targeted a number of different physical functions. Most studies reported that they had used some form of safety measure during intervention. None of the studies reported serious adverse events. However, only 21 studies (35%) reported on whether adverse events occurred. Twenty-four studies reported on adherence, but only seven studies (12%) compared adherence to exergaming with other forms of exercise. Clinical measures of balance were the most frequently used outcome measures. PEDro scores indicated that most studies had several methodological problems, with only 4 studies fulfilling 6 or more criteria out of 10. Several studies found positive effects of exergaming on balance and gait, while none reported negative effects.

CONCLUSION

Exergames show promise as an intervention to improve physical function in older adults, with few reported adverse events. As there is large variability between studies in terms of intervention protocols and outcome measures, as well as several methodological limitations, recommendations for both practice and further research are provided in order to successfully establish exergames as an exercise and rehabilitation tool for older adults.
