Abstract
Abstract
Introduction: Osteoarthritis of the knee belongs to
the diseases with the greatest disability. The changes
caused by osteoarthritis seriously affect the stability
of the knee joint. Joint stability is affected by muscle
strength, proprioception and ligament laxity. The
importance of the use of proprioceptive exercises in
therapy in persons with osteoarthritis of the knee has
been recognized. Nevertheless, there is currently no
widely accepted measure of clinical outcome aimed at
neuromuscular control of patients with osteoarthritis of
the knee.
Aim: The aim of this study was to evaluate the reliability
of the Y-balance test as a reliable indicator for measuring
dynamic stability in people with osteoarthritis of the
knee and to determine the impact of therapeutic
proprioception exercises on increasing dynamic stability
in people with osteoarthritis of the knee.
Materials and methods: The study was conducted on a
group of 19 subjects, patients with osteoarthritis of the
knee. A Y-balance test modeled on the SEBT test was
used in the study. Measurement by Y-balance test was
performed 3 times. The first and second measurements
calculated the reliability of the Y-balance test by
the Test-retest method, while the second and third
measurements assessed the impact of therapeutic
proprioception exercises on dynamic stability in
people with osteoarthritis of the knee. Respondents
were divided into two groups in the second and third
measurements. The experimental group of subjects
had a 10-day physical therapy that included standard
therapeutic exercises and proprioceptive exercises,
while the control group had a standard exercise program
for knee osteoarthritis. In both groups of subjects, TENS
therapy was applied to both knees for 15 minutes.
Results: The result of the Pearson correlation coefficient
for the composite score of the left foot is 0.93 and
the right 0.97. The correlation is positive, very high
and statistically significant with a risk of less than 1%
(p <0.01). The combined program of standard and
proprioceptive exercises had a statistically significant
effect on increasing the dynamic stability measured by
the Y-balance test with a risk of less than 1% (p <0.01).
The standard exercise program had a statistically
significant effect on increasing the dynamic stability
measured by the Y-balance test with a risk of less than
5% (p <0.05). Comparing the control and experimental
groups, the results of the Y-balance test did not show
a significant difference between the groups (p <0.05).
Conclusion: The Y-balance test modeled on SEBT
can be reliably used as a good indicator of dynamic
stability in a composite measurement result in persons with osteoarthritis of the knee. Although there is no
statistically significant difference in improvement
between the groups, the experimental group showed
a slightly higher percentage of results than the control
group. If the research was conducted on a larger
group of subjects and after several days of therapeutic
treatment, it is possible that the results would be
statistically significantly higher in the subjects of the
experimental group.
