- Scientific TitleThe effects of a short-term exergame balance training on postural control and balance recovery reactions of older adults.
- hypothesisFalls are one of the greatest concerns among older adults, because the incidents are high and they lead to severe consequences. The extent of the problem will continue to expand as the number of older people is expected to increase dramatically over the next few decades. An important risk factor for falls in older adults is an impaired postural control, which is defined as the act of maintaining, achieving or restoring a state of balance during any posture or activity. A growing number of studies show the potential of video games incorporating training (exergames) to improve postural control. However, scarce evidence is available that these interventions actually contribute to a decrease in fall risk. In a previous study (METC nr. 2013/271) indicators for improved postural control were identified, by examining age-related differences in postural control and balance recovery reactions in response to a ‘near’ fall. By studying the effects of a short-term exergame balance training (ice-skating game) on these indicators, insight into within subject improvements on postural control and/or balance recovery reactions after playing an exergame will be gained. The results will provide further insights in the prospects and possible effects of a long-term exergame training to prevent fall risk, required before a large clinical (randomized) trial can be conducted to validate the exergame training.
- Healt Condition(s) or Problem(s) studiedBalance, Prevention, Falling, Older adults
- Inclusion criteriaTo qualify adults are aged between 65 and 90 and are able to walk 15 minutes without aids, understand verbal instructions and the ‘written’ informed consent and information letter and have the visual ability to perceive the information presented on the screen
- Exclusion criteriaOlder adults who are not able to walk without aids, with orthopaedic or neurological disorders which prevent them for standing and reaching, have visual or hearing deficiencies that prevent them from perceiving or hearing presented information or/and have cognitive impairments that prevent them from understanding our instructions. Regular skaters (i.e. weekly training) are excluded as well.

- InterventionsThe total exergame training consists of 45 minutes; the first day the game will be played in two blocks of 15 minutes. The second day the participants perform one block of 15 minutes exergame training, to avoid that fatigue would affect the results on the posttest. Depending on the scores, which are based on the speed and the accuracy (avoiding holes in the ice and bending to cross a bridge) of the ice-skater, the difficulty level will increase. Although the game will then become more difficult (number of holes to avoid increases; the distance to skate is longer) the same lateral weight-shifting movements are required to move the avatar on the screen.
As pre- and posttest three balance tests are performed:
- Balance perturbation test:A ‘near fall’ will be simulated by sudden, laterally directed, platform translations, during the performance of multiple reaching tasks.
- Target-directed weight-shifting test:Participants will perform several target-directed weight-shifting movements to targets in different directions, by leaning with their whole body while keeping both feet in place.
- The Narrow Ridge Balance Test: People will stand for 20 seconds with one leg on ridges of decreasing width
- Primary outcome- Study parameters of the balance perturbation test
o Response types: in-place response or stepping response; single step, multiple steps and ‘fall’
o Balance recovery in terms of bodily displacement: step length, step width, presence of an APA (anticipatory postural adjustment), COM displacement, COP displacement and accelerations.
o Balance recovery in terms of reaction times: onset latency (time to initial response), time to foot-off, time to foot-contact
- Study parameters of the target-directed weight-shifting test: accuracy, fluency and speed of the weight-shifting movements based on the CoP trajectory and the duration of the weight-shifting movement[26].
- The Narrow Ridge Balance Test (NRBT) is a test that is sensitive to assess balance performance in older adults. Because the difficulty of the test increases with the balance capacity of the participants ceiling effects are avoided, and each participant is exposed to a maximally challenging task.
- Secondary outcomenot applicable
- TimepointsBefore-after design. The three balance tests are performed as pretest on the first day before the exergame training and as post-test on the second day after the exergame training.

- Brief summaryThe present study consists of a short-term exergame training preceded and followed by three balance tests. One group of 15 older adults will play the exergame and one group of 15 older adults will play a conventional ‘fun’ game (Angry Birds) on the iPad. With this study insights will be gained in within-subject improvements in postural control and balance recovery reactions after a short-term exergame training. Results of this experiment will provide further insights in the prospects and possible effects of a long-term exergame training to prevent fall risk, required before a large clinical (randomized) trial can be conducted to validate the exergame training.
