Effect of electrical stimulation on quadriceps muscle after total knee replacement
Martina Đorđijevski
Abstract
Abstract
Introduction: The implantation of total knee
endoprosthesis is today an increasingly frequent
lyrical surgery aimed at eliminating pain and improving
function in people with osteoarthritis and other
conditions that require a change of joint (rheumatoid
arthritis). Although muscle weakness is a common
finding in the postoperative process, due to the longevity
of muscle recovery, the greatest attention is directed to
m. quadriceps along the posterior lodge of the thigh
muscles, due to its responsibility to carry out normal
functional activities such as walking and climbing stairs.
Aim: To determine the strength of m. quadriceps,
thigh circumference and mobility of the knee joint of
patients with implanted total knee endoprosthesis
who performed classic static and dynamic exercises
for m. quadriceps and in patients who, in addition to
classical exercises, performed electrical stimulation for
m. quadriceps.
Materials and methods: A convenience sample was
used (N=60). A manual muscle test was used to
assess muscle strength, and the circumference of the
quadriceps was monitored, measured at two levels. The
mobility of the knee was measured with a protractor and
the movement of flexion and extension of the lower leg
was measured.
Results: The analysis of the first and second
measurements in the experimental group showed a
statistically significant difference in the measurements
of extension, flexion and manual muscle test, while
there was no statistically significant difference in the
measurements of the circumference of the upper leg
at the level of 15 and 10 centimeters. The analysis
of the first and second measurements in the control
group showed a statistically significant increase in
the values in knee flexion and extension movements
and in the manual muscle test, while there was no
statistically significant difference in the circumference
measurements at 15 and 10 centimeters. By comparing
the obtained final results between both groups, no
statistically significant difference was obtained in any of
the tested areas.
Conclusion: After the therapy, a positive shift is visible in
all tested areas compared
