Karartı, C., Investigation of the Relationship Between Foot-Ankle Characteristics
and Lumbopelvic Control, Balance and Physical Performance in Healthy Young
Adults. Hacettepe University, Institute of Health Sciences, Neurology
Physiotherapy Program Master Thesis, Ankara, 2018. This study was designed to
investigate of the relationship between foot-ankle characteristics and lumbopelvic
control, balance and physical performance in healthy young adults. A total of 64
young adults, 26 females and 38 males between 18 and 25 years old, were included
in study. Foot-ankle characteristics were assessed by navicular height test, navicular
drop test, foot posture index, plantar pressure analysis and isokinetic strength
dynamometer after the sociodemographic characteristics of the individuals were
recorded. Ultrasonographic imaging method and spesific endurance tests were used
for assessment of lumbopelvic control of individuals. Balance was assessed by Biodex
Balance System and single leg stance test and physical performance was assessed by
vertical jump test, side step test and shuttle running test. It has been found that
increased pressure in medial part of foot and low medial longitudinal arch formed by
increased rearfoot pronation affected m. transversus abdominis and m. lumbar
multifidus muscle thickness, static and dynamic balance as well as physical
performance negatively (p <0.05). As the rearfoot pronation increased, especially
decrease in plantar flexion muscle strength affected lumbopelvic stability negatively
(p <0.05). It was found that lumbopelvic control had a effect especially on overall
stability and anteroposterior stability indexes in terms of static and dynamic
parameters in Biodex Balance System. As the muscle thickness of m. transversus
abdominis and m. lumbar multifidus decreased, the index points increased and the
balance deteriorated (p <0.05). It has been determined that in addition to the
deterioration in the foot posture, weaknesses in m. transversus abdominis and m.
lumbar multifidus have important effect in balance disorders according to results of
our study (p<0.05). Weaknesses in m. transversus abdominis and m. lumbar
multifidus, which are important muscles in lumbopelvic stability, affected the
physical activities of individuals such as running and leaping negatively (p <0.05).
While anomalies in the foot posture affect physical performance adversely (p <0.05),
physical performance becomes worse as the stability of muscles that provide
lumbopelvic control decreases (p <0.05). The results of our study showed that the
biomechanical and musculoskeletal structure of the distal foot-ankle affected
lumbopelvic stability. Protective programs of lumbopelvic stability are important in
terms of prevention of postural disorders or injuries that may occur in the foot and
the other upper alignment. We believe that the addition of applications related to
lumbopelvic control, balance and physical performance to the treatment programs
planned for the individual with any foot posture problem is important for functional
recovery.
