Resumen
The present research aimed to determine the
biomechanical conditions of walking on flat
surfaces in people with knee osteoarthritis,
obtaining curves that can be compared with
others, but without knee involvement. 7 Xsens
MTw Awinda inertial sensors located in the
pelvis, quadriceps, tibialis anteriors and feet
were used. Three measurements were made to
each adult and they were classified to establish
average curves, those that presented anomalies
or noise were discarded, for the study three types
of statistical methods were used: RMSE,
Pearson's correlation coefficient and the R2
determination coefficient. This pathology is one
of the most common and frequent in comparison
with other joints of the body, because the knee
joint is a joint that "supports weight", that is, for
every 4 kg of weight that we gain, our knee
supports 18 kg more force when walking. People
who are over 20% overweight have a 10-fold
increase in risk of osteoarthritis [1]. The gait
pattern, in addition to being affected by knee osteoarthritis, can be altered by causes such as
overweight, height, footwear, hormonal
pathologies and fractures and trauma, as a result
of these affectations we have the elderly P2 with
a coefficient of determination of 0.49 % in pelvic
obliqueness, 0.84% in knee flexion and
extension. The results were favorable, reaching
expected results, which in the same way
encourage that more people should be
considered for the study, considering the state in
which their disease is advanced, in order to have
a characteristic curve according to the stage in
which each older adult is.
