Introduction.
Physiopathological aspects related to growth, aging process and
osteoarticular pathology, corelated with the overtraining
process in sport, are of most interest for the health care.
Awareness of these problems can help the developpment of new methods of
evaluation and rehabilitation in human movement,
with clinical applications, leading to
limitations of social and economical costs in healthcare but
also with impact in increasing performance in sport activities. At the
present time, different methods in approaching and
evaluation of movement are presented in the
literature, but the choices are unilateral, without a
common approach based on interdisciplinary researches which
would help in obtaining of better and quicker
results. For this reason, the present paper intends to
present a new and complex system of aquisition and
analysis of motion data with direct applications in
sport and rehabilitation, utilised within the
research programme CEEX-M-C2-2358/2006 entitled
“Individualized management of mobility recovery of patients
with neurological and orthopedic pathology using new
methodologies for interdisciplinary research –
MANMOBREC” coordinated by the University of
Craiova.
Material
and methods. The present study wishes
to present the use and interpretation of plantar pressure measurement
using the RSscan footscan systems. For this purpose
we will briefly present the characteristics of this system,
as a new and recent method in sport and rehabilitation. A
metaanalysis of present studies regarding the relationships
between gait biomechanics and prospective studies of trauma risk
factors for the lower limb will be followed by presentation of our own
results in using this device. We involved 20 patients (age range 5-10
years) suffering different neurological pathologies (PF
group) and a control group of 10 healthy persons (same age) with no
complaints and
no pathology during examination (C group).
The diagnosis of neurological pathologies was made by history
and physical examination. Measurements were made on a 0,5 m
footscan plate and calculations were made using the gait scientific
software. Examinees were asked to walk barefoot at a
self-selected speed along a 8 m walkway. A Footscan pressure plate
(RSscan International, Belgium, 0,5 m x 0,4 m) was mounted in the
middle of the walkway. Distribution of pressure between the medial and
lateral part of the forefoot was evaluated. Balance between the medial
and lateral part of the forefoot was calculated using formula
((M1+M2)-(M3+M4+M5)). M is pressure under metatarsal joint 1 to
5. The mean value of stance phase and balance for both groups
were calculated. Measurement were carried before and after
rehabilitation or surgical treatment.
Results. This is a
pilot study and it is planned to evaluate the treatment effect on
walking in neurological pathologies by using the data measured by
RSscan platform as an evaluation method of the progress. Also
the study contributes in gaining datas for this new method, as many
universities work for that issue, available data in the literature
being still a few. Extension of the research
results were made by elaboration a data base available for
all potential users. Correction in some cases will be made by using the
Foot Advisor software.
Conclusions.
As walking Is a complex movement, the purpose of our study
was to evaluate the lower limb biomechanics
providing a reliable and representative reference
dataset for plantar pressures measured at a 350
Hz frequenty of data acquisition
underneath weight-bearing anatomical areas
for barefoot walking, offering a systematic method of
collecting the information. We conclude that we attained this goal
by using a semi-automat procedure, baised on the geometry of
the food and a qualitative interpretation of pressure distribution on
the footprint, which allows a reliable and repeatable matching of
sub-areas underneath the sole to anatomical structures of the foot.
