| Introduction:
Patellfemoral pain syndrome is one of the most common knee joint problems that
affect athletes and non-athletes. Knee brace is often used as a treatment method for patellar realignment.
The aim of the present study was to determine the effects of a patella support
brace on myoelectric activity of selected knee muscles during single leg
landing in healthy females. Materials
and Methods: 19
healthy female students (Mean age: 23.6±1.98 years, height: 163.5±5.88
cm, weight: 62.3±3.6
kg) participated in this study. Myoelectric activity of biceps femoris,
semitendinosus, vastus medialis and vastus lateralis were collected during
single leg landing in with and without using the patella support brace
conditions. Results: Use
of the patella support brace had no significant effect on myoelectric activity
for the semitendinosus (p=0.668), vastus medialis (VM) (p=0.915) and vastus
lateralis (VL) (P=0.134), while myoelectric activity for biceps femoris
(p=0.005) and ratio of VM/VL myoelectric activity significantly increased
(p=0.045). Conclusion: Our
results revealed that biceps femoris activity and vastus medialis/vastus
lateralis ratio increased after using patella support brace during single leg
landing. Further studies on kinematic and kinetic variables are needed to
describe these changes in muscular activity when using the patella support
brace. |
