us to perform this investigation. There is two purpose of the investigation. Main purpose of
the investigation is comparison of peak pressure, average maximal pressure and pressure-time
integral pedobarography parameters on the plantar regions of elite male horon dancers and
sedentary healthy individuals. Generally shoes used in folk dance are sandal type, thin and flat
based shoes. These shoes do not support any part of the feet and it is possible that this kind of
shoes may cause problems in the plantar region. Besides, since horon is played by faster and
sterner by male performers than female performers, this study is conducted in male
individuals. Second purpose of this study is the investigation of possible plantar pressure
differences aroused as a result of horon in the male individuals and determination of the load
per metatarsal and usage of correct shoe and contribute the shoe development studies.
2. Method
18 male (average age; 22,60±3,1) horon playing folk dancers who represents Turkey in
international level and 25 male volunteers (average age; 26,10±2,4) as a control group is
included in the study and the ones who undergo feet and ankle surgery and ones who has a
previous fractures in the area does not included in the study. Required approval is obtained
from T.C. Gazi University Medical Faculty Ethical Board.
Pedobarographic (plantar pressure measurements) analysis is performed on the
volunteers. Pedobarographic analyses are performed on the Gazi University Faculty of
Medicine Orthopedics and Traumatology ABD laboratory by employing EMED-SF (Novel H,
Munich, Germany) plantar pressure analysis system. This system is formed of a platform in
the dimensions of 44.4 x 22.5 cm which includes two sensors with 71 Hz sampling speed and
covered with leather and mounted upon a 7x1 m long wooden platform
Participants are asked to take at least three steps before come upon the pedobarograph
and measurements are taken with bare foot. One static and two dynamic measurements is
performed for each feet.
Plantar is separated 11 different regions named as mask, and peak pressure, maximum
average pressure (N/cm²) and pressure time integral [(N/cm²)*s] is measured and analyzed.

Investigation of the effect of playing horon on plantar pressure distribution on folkdancers

Statistical Assessment
Analysis of the data is performed with SPSS 18 package software. Averages are taken from
the two measurements of the subject and control groups and the presence of a meaningful
difference between them is measured by Mann Whitney U test, the magnitude of the linear
relationship between physical structure and plantar parameters is measured with calculation of
Pearson’s (r) coefficient. In the measurements % 95 confidence interval and P<0.01 – 0.05
limit of significance is accepted.

The differences of age, body weight and BM averages between folk dancers and the
control group is found to be meaningful in the level of P<0.01. Age, height, body weight and
body mass index values of the volunteers are higher than the folk dancers in the subject group.
