Purpose: The purpose of this study is to determine if the
Nintendo Wii Balance Board (WBB) can accurately measure
balance in community-dwelling elderly population using
center of pressure (COP) measurements.
Relevance: The force platform (FP) has been used to measure
sway in static standing postures through using COP data.
The WBB utilizes a similar technology to identify the COP
of the individual standing on the board. The WBB, if valid,
may be an economic alternative to FP in clinical practice and
research.
Participants: Fifteen community-dwelling elderly individuals
over the age of 65 years agreed to participate and signed
an Institutional Review Board approved informed consent.
Participants were included if they were without major health
condition, lower extremity disability, and can stand without
an assistive device for at least 30 seconds.
Methods: The participants were divided into two groups,
with and without balance impairments using the Activities-
Specific Balance Confidence (ABC) scale, and the Berg
Balance scale (BBS). Participants were tested using the WBB
and the FP. Each participant was asked to stand with feet
together eyes opened and eyes closed for 30 seconds on the
WBB and FP in a random order.
Analysis: To determine the test–retest reliability, participants
performed the same stances on WBB and FP three times.
To determine the validity of the WBB, Pearson correlation
coefficients were obtained for WBB, FP and BBS.
Results: Data from 15 participants showed that the mediolateral
COP sway demonstrated significant (p < .005) moderate
correlation between FP eyes opened trials (r = .62) and highly
correlated during the eyes closed condition (r = .91). The
WBB showed significant (p < .05) high correlation between
eyes opened trials (r = .92) and eyes closed trials (r = .96). In
the anterior–posterior sway both FP and WBB showed significant
(p < .005) and high correlations between trials (range
r = .82–.92). The WBB also showed significant (p < .005)
validity and was moderately correlated to the performance
on the FP during the eyes opened on the anterior–posterior
sway (range r = .5–.78) and high correlation during the eyes
closed conditions (range r = .71–.81). Neither the FP nor the
WBB was correlated to the BBS.
Conclusions: The results indicate that the WBB is a valid tool
when measuring COP sway in community-dwelling elderly
individuals. As an emerging tool in the clinical setting, the
WBB is able to provide clinicians with more objective data
to incorporate into the examination and plan of care.
Implications: Therefore, as compared to a FP, the WBB is an
inexpensive and portable instrument that will aid clinicians
in the identification of balance impairments.

Purpose: To evaluate and compare the strength of respiratory
muscles of healthy boys actively participating in swimming,
judo or indoor soccer as well as inactive boys.
Relevance: In the presence of chronic respiratory diseases,
the respiratory muscles are overloaded and there is usually
an indication for a strengthening program for this muscle
group. Several methods of training can be used, and physical
activity is regarded as one method with significant potential.
In children, studies in this area are limited, especially with
regard to the effects of different sports on the strength of
respiratory muscles.
Participants: One hundred and twenty healthy boys,
eutrophic and aged 7–8 years.
Methods: This was a cross-sectional study conducted with
120 healthy boys. They were divided into four groups of 30
boys each: inactive (S); indoor soccer; judo and swimming.
Physical activities were held twice a week. The maximal
respiratory pressures were measured with an aneroid-type
manometer, based on the recommendations by American
Thoracic Society/European Respiratory Society (2002).
Analysis: The comparison between respiratory muscle
strength of the four groups was analyzed by a one-way
ANOVA test, followed by the post-test Tukey Kramer, at the
5% level of significance.
