Objectives:
Reaction time (RT) is a measure of processing speed in
the central nervous system and has been reported to predict falls
in older adults. We therefore developed a custom software, which
utilizes the portable and low-cost standard Nintendo Wii board
(NWB) to record RT. The aim of the study was: (1) to explore if
our RT test could differentiate between older and younger adults,
(2) to study learning effects between sessions, and (3) to examine
reproducibility of our RT test.
Methods:
A young (age 20–35 years) and an older study-population
(age ≥65 years) were enrolled in this within- and between-
day reproducibility study of RT. A mixed effect model was used
to explore systematic differences associated with extremities,
age, and session. Reproducibility was expressed by Intraclass
Correlation Coefficients (ICC), Coefficient of Variance (CV), and
Typical Error (TE).
Results:
The RT tests was able to differentiate older adults
from younger adults in both the upper extremity test [p
<
0.001;
−170.7ms (95% CI −209.4, −132.0)] and the lower extremity test
(p
<
0.001; −224.3ms (95% CI −274.6, −173.9)]. Moreover, no learning
effect was found between sessions with exception of the lower
extremity test between session one and three. An excellent within-
and between-day reproducibility was achieved for both the upper
and lower extremity test.
Conclusions:
A low-cost and portable reaction test utilizing a NWB
showed excellent reproducibility, no or little systematic learning
effects, and could easily differentiate between younger and older
adults in both upper and lower extremities.

Objectives:
The utility of commonly used clinical and physical-
functional tests as predictors for injurious falls in geriatric patients
needs to be examined. The aims of this study are to (1) examine
the cut-off score for the predictive value of “30-second sit to
stand test” with regard to injurious falls to improve sensitivity,
and (2) investigate any association between the cut-off score and
injurious falls when adjusted for other risk factors.
Methods:
Community-dwelling 70+ years old adults were
examined at a geriatric clinic. They were consecutively enrolled
and received a comprehensive geriatric assessment, which included
the “30-second sit to stand test”. Data on prospective injurious
falls within 12 months registered at the Emergency Department
will be recorded. The currently recommended cut-off score of less
than nine repetitions by the “30-seconds sit to stand test”, for
predicting reduced physical independence, was used. When all data
are available, sensitivity and specificity will be calculated to find
the optimal cut-off score for predicting injurious falls. A logistic
regression analysis will be performed to show any association
between the most optimal cut-off score and injurious falls when
adjusted for age, sex, and previous injurious falls.
Results:
In total 320 patients were examined at the geriatric clinic.
Mean age was 81.8 years (
±
7.2) (range 70–95). Seventy-two percent
of the examined were women. Results for optimal cut-off score of
the “30-second sit to stand test” and association with injurious falls
will be available at EUGMS 2015.

Objectives:
Exercise videogames (exergames) have gained in
popularity as a tool for improving balance ability. We developed
an exergame, enabling community dwelling older adults to train
balance in their home environment without supervision, using
affordable technology. The objective of the present study was to
assess the effects of the exergame on balance control.
Methods:
Ten healthy older adults (75.9
±
7.2 years) played a newly
developed ice-skating exergame for six weeks at home without
supervision. During gaming the speed and direction of a virtual
ice-skater are controlled by making lateral weight-shifts that are
captured by a Kinect. Before, after 2 and 4 weeks of training and
after the intervention, postural control was measured during 45
sec. of standing on a pressure mat system in eyes open (EO),
eyes closed (EC) and dual task (DT) conditions. From the center of
pressure signals sway characteristics in time and frequency domain
were calculated. Multilevel modeling with a two-level hierarchical
model was applied to examine changes in balance.
Results:
Participants played on average 631 (
±
124) minutes and no
participants dropped out. Improved sway characteristics in time and
frequency domain (P
<
0.05) were observed in EO and EC condition
after 4 and 6 weeks of training. The rate of balance improvement
showed differences (P
<
0.05) between participants, not related to
total playtime.
Discussion:
A 6-week balance training based on unsupervised
home-based exergaming improves balance ability in healthy older
adults. However, participants did not benefit equally from the
intervention, thereby emphasizing the need for a personalized
training program.

Objective:
The aim of this study was to assess the effectiveness of
a cardiac rehabilitation programme for patients with heart failure
and chronic diseases in Primary Care.
Methods:
The participants in this 6-month prospective study
were 172 consecutive patients with low-risk myocardial infarction
referred to their primary care center for follow-up care (60–89
years, 66% male). Of these patients, 97 were referred to a
mixed primary and specialized care program that included
exercise training, cardiovascular risk control, an antismoking
program, patient education and psychological evaluation (lifestyle
modification). We analyzed the results after 3 months and 6 months
of follow-up.
