Abstract: | Purpose] To evaluate the effects of balance training after arthroscopic anterior
cruciate ligament reconstruction. Subjects and Methods] Sixteen patients (mean 33 ±
8 years old) who underwent anterior cruciate ligament reconstruction three months prior to
participating in a one-month rehabilitation program. The control group included 15 people
aged 34 ± 4 years. Patients’ functional level was evaluated according to the Lysholm knee
score, and balance quality was ascertained by static and dynamic tests. A balance platform
was used to measure the center of foot pressure deflection. Two dynamic balance tests
evaluated time of task execution. Results] Lysholm knee score improved significantly
after rehabilitation. Balance in the sagittal plane with eyes closed improved
significantly after rehabilitation. The average velocity of center of foot pressure swing
in both the frontal and sagittal planes with eyes closed differed significantly from those
of controls. Execution time required for the two dynamic tests decreased significantly
after rehabilitation and were significantly better than those in the controls.
Conclusion] Maintaining static balance with eyes closed is very challenging after
anterior cruciate ligament reconstruction. Maintaining balance in the sagittal plane is
particularly difficult. A one-month rehabilitation program partially improves static and
dynamic balance.Key words: Balance training, Anterior cruciate ligament, Reconstruction |
